• Is there a PC equivalent for the Android 'Wifi Analyzer' App?

  - by Connor W

  I'm using the Wifi Analyzer app on my phone a lot at the moment as I need to set up and test some wireless networks. For people unfamiliar with the app, i've posted some screenshots of the app that I found on the internet. I'm looking for some software that will do the same or similar thing, but on a PC. I've looked on Google, but could not find anything of use. Thanks in advance for any information.

• Can't ping other machines in my network

  - by judahgabriel

  I've got 3 machines on my network, all running Windows 7. None of them can ping each other, can't see each other on the network, can't see shares, can't remote desktop, can't see any homegroups. They are all on the same workgroup. They are all connected to the same wireless, WPA2 secured network. They all worked together nicely until I added a password to my wireless network. After that, and after reconnecting all the machines to the password-protected network, they can't see each other. Any ideas what could be wrong?

• Ubuntu: disable udev's persistent-net-generator.rules

  - by Luke404

  I'm using Ubuntu 12.04 LTS server edition and I am modifying /etc/udev/rules.d/70-persistent-net.rules to define my own mappings of ethernet interfaces to MAC addresses; that file is initially generated by rules in /lib/udev/rules.d/75-persistent-net-generator.rules at system installation time (or at the first boot, I actually don't know and it doesn't matter here). How can I be sure that my edited version will never ever be overwritten by anything? Removing the persistent-net-generator, as suggested on some websites, is not the Right Thing™ to do as told by comments in the file itself: it will be overwritten by any update of the udev package. I'm looking for a more formally correct way to disable it. Is it enough to just make sure that /etc/udev/rules.d/70-persistent-net.rules does exist? Maybe there are other events that could trigger its regeneration? (eg. adding or removing ethernet interfaces to the system?)

• Can I set up a 2nd home wireless router, with router2 connecting to the internet through a desktop which is wirelessly connected to router1?

  - by gil b.

  Hi, I apologize for the crudeness of my MSPaint drawing, but please view my diagram of what I'd like to accomplish: Proposed home network architecture Currently, all devices are connected to 1 wireless router. I would like to make my own subnet, with a box in-between my subnet and the shared wireless router, so that I can learn about IDS, traffic analysis, etc. I was also given a cisco PIX firewall to play around with, and it'd be an added bonus if I could incorporate that into my network. The reason for this proposed architecture is so that I can monitor all MY traffic, without seeing anything going on with my roommates' traffic. my MAIN Question is, is it possible to have my desktop connect to the wireless router with internet via wireless card AND share that connection via the ethernet card, hooked to wireless router 2? cable modem - wireless router - desktop pc connected wirelessly - wireless router 2 getting internet from wired connection to desktop pc - laptops connected wirelessly The PIX can be left out for now, but I'm wondering if it could eventually be incorporated? THANKS!

• network user isolation

  - by seaquest

  My question is for a network with a Linux iptables router gateway. How can it be possible to prevent inter-network traffic of those users. Think this case as a public network, IPs are distributed through linux gw and users are authenticated thru the gateway. We want to protect public users from public users. Network is not wireless and I can not use Wireless AP user isolation. Actually I have a simple method. Subnet the network into /30 mask. Give minimum IP of each subnet to the gateay and ditribute those /30 IPs from the subnet. But this is pretty costly for such an aim. I want to ask for other methods Thanks.

• Resolving loss of internet bandwidth in home network

  - by Caspar

  Recently, I've decided to connect my laptop at home to my modem/router through Ethernet cables built into my apartment. As these built-in Ethernet cables are usable via plugs built into the walls (called powerline adapters), I use some additional cabling (STP CAT6 cables) from my laptop/router to the plugs. In addition, I don't know any technical details about these built-in cables (as they're not visible), only the maximal bandwidth (1 GBit = Cat6?) that they're supporting. The built-in cables are Cat. 5e Ethernet cables. The problem is now that when I set up the connection, I cannot use the full bandwidth that my internet connection is actually offering (100 Mbit/s), only about 85 Mbit/s between 85 - 88 Mbit/s, despite the fact that all cables involved should support the maximal bandwidth. I know from other tests with one of the Ethernet cables in use that I can use almost 99 Mbit/s when I connect my laptop directly to the router/modem using only this one cable. In addition, it is very unlikely that the length of the resulting cable connection from my laptop to my router involving the built-in cables exceeds 100 m. So, what possible reasons for this loss of bandwidth exist? And how I can fix this issue? I hope this might help resolve the issue: The built-in cables appear to be Cat. 5e Ethernet cables. So, is there any problem when I connect Cat6 Ethernet cables directly to Cat5e Ethernet cables via the plugs?

• Accessing Windows from Linux/Mac by name using TCP/IP

  - by stevekuo

  What are some solutions to access Windows by its computer name from Linux and Mac using TCP/IP. That is, from terminal I want to be able to ping my Windows PCs using its host name. My setup is: Various machines running Ubuntu, Windows XP and OS X. Networked using a consumer grade wireless router which provides DHCP. The only DNS is the ISP's, which resolves Internet names and not local host names. The Windows machines can ping each other by name. The Ubuntu and OS X machines can only ping Windows by IP address (name doesn't work).

• Audio and video streaming using Network Simulator in Linux

  - by Parth_90

  I am working on a project which is to show the simulation of streaming of audio and video data in wireless networks. I want to show the simulation that involves a base station, with few wireless stations. The base station should start sending data once it computes a certain value . On receiving the data, each wireless must begin communicating with the base station. I have gone through basic NS-2 tutorials from over here but I am not getting how to go about integrating it with my project. Can anyone tell me how to do it using NS2 or any other network simulator?

• Linux wireless disconnect every 20 minutes

  - by james

  My laptop uses CentOS 6.3 with kernel 2.6.32-279.el6.x86_64. My wireless adaptor is Intel Corporation Centrino Wireless-N 1000. My wireless connection always get off after about 20 minutes. The network applet shows the connection is still on with good signal strength, but I just cannot load any web pages even the configuration page of the wireless router. The problem will continue until I disable and reconnect the wireless. Other devices like my cell phone uses the same wireless network without the problem. Even yesterday I'm using the same laptop with Fedora 17 without this problem. I also searched the internet and someone said running services NetworkManager and network simultaneously may be a problem. But I cannot stop any one of them because: if I stop network and start NetworkManager, the network service will start automatically; if I stop NetworkManager and run network, it says "Device does not seem to be present, delaying initialization." when trying to bringing on the wireless. What shall I do to get rid of the problem? Thank you very much!

• Recommending simple appliance for DansGuardian, iptables, snort inline

  - by SRobertJames

  I'm currently using a Linksys E2000 with dd-wrt. I'd like to add DansGuardian for Content Filtering and snort-inline for IPS; but those require a more powerful box (mainly, more storage). Can you recommend a good device to use? I'm open to both overwrite-the-firmware (like dd-wrt) and designed-to-be-customized boxes. Requirements: 1. 5+ Ethernet ports, pref. GigE 2. small form factor 3. No noise (office environment) 4. low power 5. Not sure about 802.11 wireless Budget < $400, pref. less.

• Need advice to choose correct wi-fi drivers for Dell Vostro 3560

  - by overdriven

  I'm having problems with my Dell notebook's Wi-Fi, it can't see some of the available access points, despite they are close and I used to be connected to them yesterday. Other notebooks and my phone can see them. I believe it's a driver issue, since after installing system I haven't downloaded any network drivers. I went to Dell's website to search for them but I have no idea which should I choose. For my Dell Vostro 3560 and system Windows 8.1 64bit these are available: Intel Smart Connect Technology Application APP_iSCT_W8.1_A00_Setup-TJW84_ZPE.exe (23 MB) Vostro-3560_Network_Application_TJW84_WN_4.2.40.2418_A00.EXE (29 MB) Dell Wireless 1704 WLAN 802.11b/g/n (2.4GHz), Bluetooth v4.0+HS Driver DW1704_W8.1_A00_Setup-K1HGN_ZPE.exe (239 MB) Network_Driver_K1HGN_WN_6.30.223.143_A00.EXE (247 MB) Dell Wireless1703 802.11 b/g/n, BT4.0 + HS Driver Dell Wireless1901 802.11a/b/g/n (2.4GHz and 5GHz), Bluetooth v4.0+HS Driver DW1703_DW1901_Win8.1_A00_Setup-7FPWR_ZPE.exe (265 MB) Network_Driver_7FPWR_WN_10.0.0.263_A00.EXE (272 MB) Realtek RTL8105E/RTL8111E Ethernet Controller Driver LOM_Realtek_W8.1_A00_Setup-0XCVW_ZPE.exe (6 MB) Network_Driver_0XCVW_WN_8.018.0621.2013_A00.EXE (12 MB) Intel® Centrino® Wireless-N 2230 Bluetooth Driver BT_Intel_W8.14_A00_Setup-XR83W_ZPE.exe (31 MB) Network_Application_XR83W_WN_3.1.1307.0362_A00.EXE (37 MB)

• Setting up dual wireless routers

  - by JasCav

  I have two wireless routers (one is the router supplied by Verizon - MI424-WR ActionTek and the other is DD-WRT Buffalo router). I want to set them up so that I have the second router (Buffalo) on its own subnet and two SSIDs so I can put different devices on different routers and so I can put my web server on the first router and put most of my other computers behind the second router for a little extra protection in case of a compromise. From my understanding, I have to hook the two routers together so that the LAN from the Verizon router plugs into the WAN port of the Buffalo router. This is where I get stuck. What settings do I need to look for to setup the Buffalo on its own subnet? Do I need to do anything with the Verizon router, or are the configuration changes done to the Buffalo?

• How to tell if you are connected to Wireless B, G or N?

  - by Raheel Khan

  I am using Windows 7 on all wired desktops and wireless laptops in my home network. I recently upgraded my Ethernet switch to Gigabit and instantly noticed an increase in throughput in wired devices. I also bought a Wireless-N WAP but with degredation in wireless file transfer speeds. I have been told that a number of reasons could affect wireless speeds including which WAP is used, how many wireless devices are connected, which security mode is used, etc. However, that remains irrelevant to my question. Each of my laptops claim to support Wireless-N but I cannot seem to figure out how to determine if the laptops are truly running Wireless-N or are connected to the WAP through some sort of mixed-mode. I do not have control of the WAP device so cannot tell what mode it is running in. Is there a way to tell which mode is being used and what the throughput is for each connected device without having access to the WAP interface?

• What's the fastest way to store/access large files?

  - by philfreo

  I do a lot of video editing on my Mac and need a way to store very large (30 GB) files, and don't have room on my HD. A USB/Firewire external hard drive would work, but it seems way too slow for consistently working with such large files. I've also considered buying another computer, with a large hard drive, and putting it on the same network with a shared folder. What's the fastest / most efficient way to do this? Please consider USB 2.0 speeds, hard drive read times, ethernet speeds, etc. Are there other options I should consider?

• How can I hide my network connections in the task bar when I'm not connected?

  - by CodeSlave

  How can I hide my network connections (the PC with the red X icon on the task bar) when I'm not using a that connection. Typically, I switch back and forth between wireless and wide connections depending on my location, so I don't want to just simply disable the network device.

• After connecting wlan0 to bridge interface (and then removing it), can't connect to AP

  - by gmonk

  I'm on a laptop running Debian Jessie with kernel 3.13-1-amd64; lspci shows that my wireless NIC + driver is 04:00.0 Network controller: Intel Corporation Wireless 3160 (rev 83) Subsystem: Intel Corporation Dual Band Wireless-AC 3160 Kernel driver in use: iwlwifi This has been working without any problems, until I tried creating a bridge for lxc containers to use.

I'm not sure what I did wrong, or what step I've skipped in trying to get wlan0 back as a non-bridged device -- I removed it from the bridge and then deleted the bridge itself. Any ideas?

• Detect an IP address of a Wireless Access Point device

  - by dempap

  I have a Wireless Access Point device (http://www.szedup.com/show.aspx?id=1706), which I am planning to put into BeagleBoard-xM, in order to achieve wireless communication (LAN). However, I can't find it's IP address. I mean, I have to know it's IP address in order to connect with BeagleBoard-xM via a terminal emulator. For the moment, I have this device connected via Ethernet on my router. My router's setting page shows I have this device connected, but no further information. Is there any way to find the IP address of the Wireless Access Point? I hope of being understood. Any help would be really appreciated.

• Windows 8 doesn't automatically join Wi-Fi network if Ethernet connection is active

  - by Herb Caudill

  In Windows 7, my laptop would automatically join both an Ethernet network and the Wi-Fi network in my house (both going through the same router). In Windows 8, if the Ethernet connection is present, it doesn't join the Wi-Fi network at all. The reason I noticed this is that if Wi-Fi isn't active, I don't see my AirPlay speakers. My wireless printer is also unavailable until I manually connect to Wi-Fi. To recap: When I turn on my computer and it's connected to Ethernet, this is what my Network Connections control panel looks like: After I manually join my Wi-Fi network, it looks like this: I would prefer for it to join both networks automatically on startup, the way it did in Windows 7. Is there a way to make this happen?

• How can I connect my Xbox to my Mac on my network

  - by codecowboy

  I have a wireless router/modem (Router 1) in my living room. This is connected to the internet (cable). Wireless is disabled as the router has a terrible wireless range. My Xbox is connected via ethernet to Router 1. Another LAN output from Router 1 connects to a powerline adapter. Router 1 acts as a DHCP server on 192.168.0.x and has the IP 192.168.0.1 In a second room I have Router 2. This has the powerline feed from Router 1 going into the WAN socket. This router runs the Tomato Firmware and acts as a wireless router for the rest of the house using the IP range 192.168.1.x. Router 2 IP is 192.168.1.1. My Mac is connected to Router 2 using a LAN cable and has the IP 192.168.0.133. Several mobile devices need wireless access. I want an ethernet connection to my Mac, not wireless. I should be able to use software like Connect360 to share media from my Mac to the XBox but the XBox does not see my Mac. I can ping 192.168.0.1 from the Mac. Is this possible using my current setup? If so, how?

• IP camera's multicast/RTSP conflicting with 2.4GHz Wi-Fi?

  - by jayson

  Here at our business we have a Netgear R7000 running DD-WRT. I have been slowly adding IP cameras which I run using Blue Iris software. The last camera I bought (which is NOT a wireless camera), when I plug it into the network I start having really bad connection issues on the 2.4GHz Wi-Fi network. The 5GHz works fine, just the 2.4GHz all of the sudden has trouble connecting, as if it's conflicting. I've tried playing with the camera settings, different IP addresses, HTTP ports, etc, and discovered it to be a conflict with multicast. When multicast is checked, the Wi-Fi has issues but my video streams via Blue Iris. When unchecked, Wi-Fi works fine but the video won't stream through Blue Iris. The problem is there are no settings in the camera to change the RTSP port, which is set to 34567. Does anyone know something that could fix this issue? It all seems very strange to me but maybe someone has an idea?

• TCP connection between PCs in home wi-fi network

  - by Nordvind

  I want to establish a connection between 2 PCs. Point is to practice in writing client-server applications and similar stuff. I've heard around, that I can access another PC in network by address like "Router IP:port number". Am I right or i got it wrong? So how do I configure router to let connections to certain ports? And what would address look like, if I'm, say, connecting to 80 port on my home server? P.S. Will be grateful for links to some tutorials on this matter, if any.

• pull bandwidth from wireless WAN into local LAN

  - by cortical

  We have a local network (A) of about 50 computers connected via gigabit ethernet. We get a connection to the internet using two broadband connections to a backbone and distribute the bandwidth across the 50 computers using a CISCO 1811 router, but the bandwidth is not enough for everybody. There is a campus wide wireless network(B) that has very high bandwidth, is there a device or way to setup multiple individual connections to network B and supply the bandwidth to our network A?

• 802.11g -> wired ethernet bridging not working

  - by Malachi

  Usually people want to go the other direction, but I want to take our relatively fast and stable house 802.11g signal and bridge it to ethernet. I have tried using an Airport Express (the b/g flavor) and my i7 MacBook pro, both to no avail. Word is that the b/g flavor of This flavor of Airport Express maxes at firmware 6.3 which doesn't support this kind of bridging properly. However, I expected my MacBook pro to do the job with its "Internet Sharing" feature. Alas, although my wired PC does sort of see it, it doesn't work out. Strangely, using DHCP the PC receives the same IP address as my MBP uses on the network. Less strangely, but still surprisingly, the wired ethernet port on my mac registers as the IP address of the gateway when queried with IFCONFIG. It sort of makes sense that the mac would "pretend" to be the gateway, but the whole thing just isn't working and seems configured wrong - but all the docs I see say basically "OS X Internet Sharing: click it and go". What do I do? Do i really have to buy more hardware, even though I have plenty of would-be candidates for bridging? Incidentally, the host router originating the 802.11g signal is a belkin 802.11g router, and is documented to support WDS.
