  • How can I set my TP-Link TL-WR1043ND to extend my router - modem range?

    - by Pitto
    I'd like to extend my WiFi coverage, so I've bought the TP-Link TL-WR1043ND and updated its firmware to the latest (wr1043nv1_en_3_13_4_up(110429)) but I can't find how to use its WDS function. Reading further on Super User I understand that both the modem-router (Pirelli Alice Gate) and the TL-WR1043ND should support WDS. Are there any tricks to achieve the same result - extending my WiFi range - even changing the firmware to DD-WRT or Tomato etc?

  • Wireless connected but internet not working, modem is fine because I'm typing over wifi on my android

    - by Sandro Livaja
    I can't connect to the Internet in 11.10. I tried switching my wifi card to another USB slot but nothing changed. Is it possible that the card is able to connect while not being able to receive packages? $ ifconfig eth0 Link encap:Ethernet HWaddr 40:61:86:35:11:b0 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:43 Base address:0x6000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) wlan0 Link encap:Ethernet HWaddr 74:ea:3a:8c:d5:5c inet addr:192.168.2.5 Bcast:192.168.2.255 Mask:255.255.255.0 inet6 addr: fe80::76ea:3aff:fe8c:d55c/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:12 errors:0 dropped:0 overruns:0 frame:0 TX packets:102 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1209 (1.2 KB) TX bytes:15329 (15.3 KB)

  • VPN to Buffalo WHR-HP-G300N produces a Connection Error 807

    - by Darius
    My friend has modem/router from Clear and I have sent him Buffalo router to put it between his Clear device and the Network. I walked him thru establishing VPN in DD-WRT but when I try to VPN I get a VPN Connection Error 807. I am out of ideas how to solve this. Any suggestion? Clear Modem WAN: xx.xx.xx.xx Clearn Modem NAT's to: 192.168.15.XXX Clear Modem DHCP: 192.168.15.2 - 192.168.15.2 (range is limited to that of ONE ip address) Clear Modem DMZ: 192.168.15.2 the LAN of the clear modem is 192.168.15.XXX The DD-WRT IP: 192.168.4.1 Port FWD: 1723 to 192.168.4.1 PPTP server listens on 192.168.4.1 Where is the problem with this setup?

  • Selecting primary Internet connection in Windows XP

    - by Mariusz
    There is a computer that has access to the Internet both via the local network and by a GSM modem. As far as I know, when both connections are active, the modem connection is the primary one and all data is transmitted by the modem. Because of the fact that the slow modem connection is supposed to be used as a backup connection, I want Windows to use it only when the connection via LAN is unavailable. At the same time I want the GSM modem connection to be active constantly. Is it possible to make Windows not use modem connection when there is a working LAN Internet connection? Thanks for your help in advance, Mariusz.

  • Wireless WAN (WWAN) on a Lenovo T500 - built-in or do I need a WWAN modem?

    - by Justin Grant
    I use a Lenovo ThinkPad 2055-3AU at work and I want to get a Wireless WAN data plan with a local mobile telecom provider. I've read conflicting reports online about whether my system is "WWAN-ready" or not. How can I find out which wireless WAN providers (if any) my system can support without buying a separate modem? I looked through Device Manager for anything resembling a WWAN device and didn't see anything, but I also wiped the machine when I bought it and clean-installed Windows 7 with only out-of-the-box Windows and Windows-Update drivers, so it's possible that the device is there but the drivers aren't installed. FWIW, the support page at http://www-307.ibm.com/pc/support/site.wss/quickPath.do?quickPathEntry=20553AU does not specfically list anything about Wireless WAN.

  • Establish connection with an IP camera behind a modem-router assigned with a private IP by Internet Service Provider?

    - by silvernightstar
    Most solutions out there require the modem-router to have been assigned a public IP by the ISP. After which, one can access the IP camera via a portforward setting on the router. However, my ISP only provides private IPs internal to their system (they probably have a limited pool of public IPs). So I am unable to view my IP cameras in the way described. I'm wondering if there's a way to work around this problem without having to need a public IP. Since, after all, two users on Yahoo Messenger or Facebook Chat are able to find one another and exchange data despite both sides being within the internal networks of their respective ISPs. Given that I only plan to view my IP cameras via iOS or Android running on a smartphone or tablet, any ready-to-use solutions out there?

  • Is it possible to access internet on smart-phone through usb (no wi-fi) using Laptop as the modem?

    - by Prahlad Yeri
    One of my relatives has a nokia 5235 smartphone. It is good, but the only limitation is - there is no wifi. bluetooth & usb are the only connectivity options. His laptop has an unlimited broadband but no support for bluetooth, so basically usb is the only method by which he can connect the mobile with laptop. Now, he can do a file-transfer between these two devices, but by any chance, is there a way by which we can share the Laptop's internet connection through usb to the smart-phone? So, bascially its like this: Broadband-modem = Laptop =usb= smart-phone -(want to use internet here) Are there any software or utilities available to achieve this ?

  • Advice needed: ADSL and VPN for a small company

    - by Saajid Ismail
    Hi. I need advice on purchasing an ADSL modem/router for a small company. At the moment, we are using the iBurst Wireless service for internet connectivity. I have the iBurst desktop modem, which connects to my Netgear WNR2000 router via ethernet. I am using the Netgear WNR2000 to deploy a wireless network as well. I have also set up a VPN using Windows Server 2003, and enabled the VPN Passthrough settings on the Netgear router. I am able to connect to the office network remotely without difficulty. However the problem that I've read is that the Netgear WNR2000 only supports VPN passthrough for a single session. This is simply not good enough. I need to be able to support at least 3 concurrent VPN connections immediately, and up to 5 in the near future. Now I am cancelling my iBurst Wireless service and have just got my ADSL line installed. I have to purchase an ADSL modem, and now is a good time to think of future proofing my investment. I need a good ADSL modem, that will allow me to support at least 5 concurrent VPN connections, or more, without breaking the bank. My budget is about 150-200 USD. I believe that my current Netgear WNR2000 router will be useless, except maybe to extend my wireless network in the future by a bit. Is there a solution where I can still use my Netgear WNR2000 for WiFi, for e.g., by connecting a cheaper non-WiFi ADSL modem to the Netgear router? If not, then which WiFi-enabled ADSL modem/router that supports at least 5 VPN passthroughs can you recommend? To sum it up, I need an ADSL modem/router that is: ADSL & ADSL2+ compatible has built-in 802.11n 270/300mbps WiFi (if having this feature doesn't push the price up too much) supports at least 5 VPN connections using VPN passthrough EDIT: Answer 2.10 in the following FAQ has me a bit worried - What is VPN/multiple VPN Pass-through?

  • Wifi network stopped being visible (and usable) (Linksys wag320n)

    - by s427
    Basically, my wifi network simply stopped working for no apparent reason. It doesn't appear in the list of the available networks anymore. I can see all my neighbors' networks, but not mine. It's as if it doesn't exist anymore. The internet connection (non-wifi), which goes through the same modem/router, is fine though. I already had a similar problem about one year ago (see here: Wifi network SSID not visible ), just after buying this very modem. I finally got it to work after performing two factory resets and getting rid of the Cisco "Magic" software; but this time it's not working. I use a linksys router-modem (WAG320N) which is directly connected (via network cable) to my desktop computer (Windows 7). I have (mainly) two devices that use the wifi network: my phone (Samsung Galaxy Nexus) and an Asus tablet (TF201, aka Transformer Prime). I also resurrected an old laptop computer (Dell, running Windows XP) to test that, and it doesn't see anything either (apart from the 20 other wifi networks, of course ^^). This wifi network was working just fine and has been for about a year. I haven't touched the modem settings so I have no idea what's causing the problem. I tried: making my phone "forget" about my network, hoping it would see it again after that: no luck. re-entering the network informations (SSID/password) manually on my phone: still no luck (says it's not in range) exporting the modem configuration, resetting the modem (factory reset, via modem admin), restarting it, importing the configuration: nope. factory reset, turning it off for 15 minutes, restarting, re-factory reset, and entering the configuration manually: still nothing. Has anybody experienced something similar before? Have you any suggestion to fix that? Thanks in advance. PS: to clear things up, here are the settings of my modem regarding wifi: Basic wireless settings: Configuration: manual Radio Band: 2.4GHz Wireless Network Mode: B/G/N-Mixed SSID: s427 Channel Bandwidth: Wide - 40 MHz Channel Wide Channel: 9 - 2.452GHz Standard Channel: 11 - 2.462GHz SSID Broadcast: Enable Advanced Wireless Settings AP Isolation: Disable Authentication Type: Auto Basic Rate: Default Transmission Rate: Auto N Transmission Rate: Auto CTS Protection Mode: Disable Beacon Interval: 100 DTIM Interval: 1 Fragmentation Threshold: 2346 RTS Threshold: 2346

  • Bluetooth DUN Tethering fails

    - by tacone
    I have an HTC Desire HD, with Android Froyo (2.2) and PDANet installed. I am using Ubuntu 10.10. I cannot tether it over Bluetooth either with Network Manager or BlueMan. (note, I installed Blueman only after failing with NetWork manager, and I even tried the last version from the PPA). With both my device is discovered, paired, setup. But connecting always fail. Network manager says it cannot get the details of my device Blueman says Connection Refused (111) Here are some relevant entries from syslog.

  • Using 3G/UMTS in Mauritius

    After some conversation, threads in online forum and mailing lists I thought about writing this article on how to setup, configure and use 3G/UMTS connections on Linux here in Mauritius. Personally, I can only share my experience with Emtel Ltd. but try to give some clues about how to configure Orange as well. Emtel 3G/UMTS surf stick Emtel provides different surf sticks from Huawei. Back in 2007, I started with an E220 that wouldn't run on Windows Vista either. Nowadays, you just plug in the surf stick (ie. E169) and usually the Network Manager will detect the new broadband modem. Nothing to worry about. The Linux Network Manager even provides a connection profile for Emtel here in Mauritius and establishing the Internet connection is done in less than 2 minutes... even quicker. Using wvdial Old-fashioned Linux users might not take Network Manager into consideration but feel comfortable with wvdial. Although that wvdial is primarily used with serial port attached modems, it can operate on USB ports as well. Following is my configuration from /etc/wvdial.conf: [Dialer Defaults]Phone = *99#Username = emtelPassword = emtelNew PPPD = yesStupid Mode = 1Dial Command = ATDT[Dialer emtel]Modem = /dev/ttyUSB0Baud = 3774000Init2 = ATZInit3 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0Init4 = AT+cgdcont=1,"ip","web"ISDN = 0Modem Type = Analog Modem The values of user name and password are optional and can be configured as you like. In case that your SIM card is protected by a pin - which is highly advised, you might another dialer section in your configuration file like so: [Dialer pin]Modem = /dev/ttyUSB0Init1 = AT+CPIN=0000 This way you can "daisy-chain" your command to establish your Internet connection like so: wvdial pin emtel And it works auto-magically. Depending on your group assignments (dialout), you might have to sudo the wvdial statement like so: sudo wvdial pin emtel Orange parameters As far as I could figure out without really testing it myself, it is also necessary to set the Access Point (AP) manually with Orange. Well, although it is pretty obvious a lot of people seem to struggle. The AP value is "orange". [Dialer orange]Modem = /dev/ttyUSB0Baud = 3774000Init2 = ATZInit3 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0Init4 = AT+cgdcont=1,"ip","orange"ISDN = 0Modem Type = Analog Modem And you are done. Official Linux support from providers It's just simple: Forget it! The people at the Emtel call center are completely focused on the hardware and Mobile Connect software application provided by Huawei and are totally lost in case that you confront them with other constellations. For example, my wife's netbook has an integrated 3G/UMTS modem from Ericsson. Therefore, no need to use the Huawei surf stick at all and of course we use the existing software named Wireless Manager instead of. Now, imagine to mention at the help desk: "Ehm, sorry but what's Mobile Connect?" And Linux after all might give the call operator sleepless nights... Who knows? Anyways, I hope that my article and configuration could give you a helping hand and that you will be able to connect your Linux box with 3G/UMTS surf sticks here in Mauritius.

  • What Keeps You from Changing Your Public IP Address and Wreaking Havoc on the Internet?

    - by Jason Fitzpatrick
    What exactly is preventing you (or anyone else) from changing their IP address and causing all sorts of headaches for ISPs and other Internet users? Today’s Question & Answer session comes to us courtesy of SuperUser—a subdivision of Stack Exchange, a community-driven grouping of Q&A web sites. The Question SuperUser reader Whitemage is curious about what’s preventing him from wantonly changing his IP address and causing trouble: An interesting question was asked of me and I did not know what to answer. So I’ll ask here. Let’s say I subscribed to an ISP and I’m using cable internet access. The ISP gives me a public IP address of 60.61.62.63. What keeps me from changing this IP address to, let’s say, 60.61.62.75, and messing with another consumer’s internet access? For the sake of this argument, let’s say that this other IP address is also owned by the same ISP. Also, let’s assume that it’s possible for me to go into the cable modem settings and manually change the IP address. Under a business contract where you are allocated static addresses, you are also assigned a default gateway, a network address and a broadcast address. So that’s 3 addresses the ISP “loses” to you. That seems very wasteful for dynamically assigned IP addresses, which the majority of customers are. Could they simply be using static arps? ACLs? Other simple mechanisms? Two things to investigate here, why can’t we just go around changing our addresses, and is the assignment process as wasteful as it seems? The Answer SuperUser contributor Moses offers some insight: Cable modems aren’t like your home router (ie. they don’t have a web interface with simple point-and-click buttons that any kid can “hack” into). Cable modems are “looked up” and located by their MAC address by the ISP, and are typically accessed by technicians using proprietary software that only they have access to, that only runs on their servers, and therefore can’t really be stolen. Cable modems also authenticate and cross-check settings with the ISPs servers. The server has to tell the modem whether it’s settings (and location on the cable network) are valid, and simply sets it to what the ISP has it set it for (bandwidth, DHCP allocations, etc). For instance, when you tell your ISP “I would like a static IP, please.”, they allocate one to the modem through their servers, and the modem allows you to use that IP. Same with bandwidth changes, for instance. To do what you are suggesting, you would likely have to break into the servers at the ISP and change what it has set up for your modem. Could they simply be using static arps? ACLs? Other simple mechanisms? Every ISP is different, both in practice and how close they are with the larger network that is providing service to them. Depending on those factors, they could be using a combination of ACL and static ARP. It also depends on the technology in the cable network itself. The ISP I worked for used some form of ACL, but that knowledge was a little beyond my paygrade. I only got to work with the technician’s interface and do routine maintenance and service changes. What keeps me from changing this IP address to, let’s say, 60.61.62.75 and mess with another consumer’s internet access? Given the above, what keeps you from changing your IP to one that your ISP hasn’t specifically given to you is a server that is instructing your modem what it can and can’t do. Even if you somehow broke into the modem, if 60.61.62.75 is already allocated to another customer, then the server will simply tell your modem that it can’t have it. David Schwartz offers some additional insight with a link to a white paper for the really curious: Most modern ISPs (last 13 years or so) will not accept traffic from a customer connection with a source IP address they would not route to that customer were it the destination IP address. This is called “reverse path forwarding”. See BCP 38. Have something to add to the explanation? Sound off in the the comments.

  • Setting primary internet connection and network on notebook

    I have installed Ubuntu on a notebook that I have configured to connect to the internet using an Iburst USB modem. This works 100% after a bit of configuring. I now have a desktop pc that I have installed ubuntu on, and would like to connect the two with a router. I bought a router with wifi, and would like to connect my notebook to the other computer using wifi, while still keeping the internet working with the usb modem. The problem is that as soon as the wifi connect, the internet connection dies. Is there a way to force ubuntu to get internet access through the usb modem, but use wifi to connect to the network? I am pretty new to ubuntu so any help would be appreciated. I also have a samsung galaxy tab that I would like to connect to the internet through usb modem via the wifi, so is there also a way to share that internet connection with the other computers on the network? Thanks in advance.....

  • Will disabling NAT on my wireless router cause a performance hit on my DSL router?

    - by user117313
    I have a Thomson TG508v2 router/modem and a brand new AirPort Extreme connected to it. At first, I set the AirPort Extreme to "share a public IP", which enables DHCP/NAT. Everything works great but I was having the Double NAT error. So I set the AirPort Extreme as bridge mode, which disables DHCP/NAT and let my crappy modem handle my internal network IPs. Will this cause any performance hit in my network? I'm worried because I'll outsource this job from AirPort Extreme (premium hardware) to the crappy modem. Before you suggest, I tried setting my modem as a bridge and configuring PPPoE on the AirPort Extreme, however it wouldn't connect to the internet, so I just dismissed leaving the modem as bridge.

  • Two routers on the same network

    - by qroberts
    My ISP has supplied me with a modem/router all in one and it isn't very good. It loses its settings and dies frequently. So I have another router in my apartment (Linksys wrt310n) that is connected to the modem via LAN-LAN port connections. I want to give my Linksys router the DHCP role and also have the ISP modem DMZ everything to the Linksys router. I want to be able to have all computers connected to both routers on the same network as well. I have been able to make it so that the Linksys has a DMZ to it from the ISP modem, but ISP modem LAN port - Linksys WAN port, so they were on different networks. Is there a way to have it so that both of them are on the same network but the Linksys router handles DHCP and port forwarding?

  • Why can't I install apps on Windows 8 using specific dial-up modem connections?

    - by Vincent of Earth
    This problem has persisted since I first tried out Windows 8 Consumer Preview, and also affects Windows 8, Windows 8.1 Preview, and Windows 8.1. Specifically, the problem occurs when I try to install apps from the Windows Store on a Globe Tattoo Broadband or Smart Bro dial-up connection (two common ways of connecting to the internet in the Philippines). I can confirm that this isn't a problem with my copy of Windows or my Microsoft account because I was able to install any app on other connections like public WiFi. This problem has persisted on three different dongles and two different computers. So why can't I install apps on those two specific types of connections?

  • T38modem manuals?

    - by Brian Postow
    Are there any T38modem users here? I'm trying to figure out how to call T38modem with SIP. I've got everything except the --route option for receiving. I know my own phone number, but I am not sure how to set it up. Currently, I have: --route "modem:0.*"="sip:<dn>@64.136.174.30" --route "modem:1.*=sip:[email protected]" I've also tried: --route "modem:*.*"="sip:<dn>@64.136.174.30" --route"sip:*@74.94.184.154"="modem:<dn>@127.0.0.1" what amI doing wrong? And where (other than t38modem --help) can I find some documentation on how to use it? thanks.

  • Access internal IP using public IP

    - by willvv
    Hi, I have a DSL modem with a public IP address (201.206.x.x), and I have a web server in my internal network (192.168.0.50). I set up the modem to forward requests to port 80 to my web server, so, if I access 201.206.x.x from outside my network, it shows my web page, the same happens if I access 192.168.0.50 from a computer inside my network. Now, the problem is when I try to access 201.206.x.x from my internal network, the browser tries to connect to the DSL modem configuration, instead of redirecting my request to my Web server. Which settings do I have to change in the modem to set up this redirection? Thanks!

  • configure pppoe on wrt54gl(openwrt)

    - by sunny
    Hi, I have home DSL connection from my ISP with a beetel modem at my end. I want to make my network wireless, so i bought a linksys wrt54gl and installed open-wrt on it. My ISP provides dynamic IP's with me connecting via pppoe. My question is how do I configure openwrt to work with this. Please suggest what option should I go with, or any other you recommend. DSL cable--Beetel Modem-- Wrt54gl in bridge mode with beetel modem doing the pppoe and having a DHCP server. DSL cable--Wrt54gl with wrt54gl handling the pppoe. Is option 2 possible, can I have a setup without bringing the beetel modem in the picture at all?

  • Connection Issue

    - by Karl Schneider
    Desktop computer, connected directly into a Comcast modem. Every so often, at seemingly random intervals, my connection will drop. This could be while in the middle of browsing, or when I'm not even at the computer. When the connection drops, the modem still shows 4 green lights. The modem is connected to a splitter (cable and internet in same room), and then directly to the wall. To recover from the problem, I am forced to restart my computer, at which point everything works fine again. I have tried an ipconfig/release and renew, it tells me that it is unable to contact the DHCP server, and thus can't renew. I have updated the NICs driver, no luck. I have changed the ethernet cord, no luck. I have had Comcast replace the modem, no luck. The only thing I can think of that hasn't been replaced is the cords connecting the modem to the wall and the splitter. Can anyone think of anything else I may be able to do to isolate what's causing the issue?
