  • How to turn on Airport on MacBook Pro

    - by hap497
    Hi, I am using MacBook Pro (Mac OS X 10.5). On the status bar, check I click the Wireless icon, it said 'Open Network Preferences' And then in the Network Preference, I click 'AirPort' tab, the status said 'Inactive' But the 'Turn AirPort on' is disabled and the Network Name is disabled as well. I have unlocked the preference pane as well. So how can I turn on Airport? Thank you.

  • Setting up 802.1X wireless connection on OSX

    - by hizki
    I am an OSX user, I have Snow Leopard 10.6.5 and an updated AirPort. I am trying to connect to my university's wireless network, but it has a complex security that I am having trouble defining... Here there are instructions for connecting with Windows XP, Windows 7 and Linux. Can someone please instruct me what should I do to set up this network on my MAC? Thank you. P.S. I have had previous success in setting up this network, but I have no idea what I did that made it work. Since I updated my AirPort it worked only seldomly and very slowly... Before the update, even when it worked it never remembered my password.

  • Ruckus wireless AP and Dell PowerConnect configuration problems

    - by DanielJay
    We are working on trying to get some Ruckus Access Points to work correctly on our network. Currently our network is as follows: VLAN 10 - Servers VLAN 11 – Computers/DHCP VLAN 12 – Voice VLAN 13 – Guest We use Dell PowerConnect 6248P switches for our switches. Port settings are as follows: ZoneDirector 1100 is plugged into this port. Should be accessing the server VLAN and then allowing all other traffic. interface ethernet 1/g2 classofservice trust ip-dscp description 'Ruckus ZoneDirector 1100' switchport mode general switchport general pvid 10 switchport general allowed vlan add 10 switchport general allowed vlan add 11-13 tagged exit Access point is plugged into this port. The port has to be on VLAN 11 in order to get DHCP. interface ethernet 1/g16 classofservice trust ip-dscp description 'Ruckus - IT' switchport mode general switchport general pvid 11 switchport general allowed vlan add 10-12 switchport general allowed vlan add 13 tagged exit If we tag the traffic from the SSID as VLAN 11 data fails. If we leave the SSID tagged as 1 the data flows correctly. Are there problems with passing tagged traffic to untagged ports? We are looking to see what we can do to get the SSID tagged as 11 instead of 1. Any suggestions?

  • Best dual band A/B/G/N wireless router/ap for Linux

    - by Kevin Bowling
    Hello, I am looking for the best A/B/G/N dual band (simultaneous) router or access point that can be flashed with community firmware like dd-wrt or openwrt. In the past I have used the WRT54G series from Linksys with great success as access points and bridges. The WRT610N looks nice but I'm not sure how well the community firmwares support it. I am open to any manufacturer and any input or experience would be appreciated.

  • What is the best way to setup a public and private wireless access point on the same home network?

    - by Dougman
    For my home network (with internet provided from a cable modem) I would like to setup a secure wireless access point that I use for all of my personal connections (home PC, iPhone, Xbox, etc) and also another public access point that friends and folks in the neighborhood may connect to (for good karma). I want to ensure that my private traffic cannot be accessed from users of the public access point. I currently have one router that is running the Tomato firmware that I use with WPA security. What is the best way to accomplish this kind of setup securely (if it is possible in a home environment)?

  • Not working WEP key in Ubuntu

    - by stupid-idiot
    This time I've got some problem with connection to the internet from my old laptop with ubuntu, I already had some problems with setting up the radio on my network card but I think it works now since it finds some wireless networks. The problem is that I can't connect to my router via wi-fi even if I'm hundred-percently sure the wepkey I punch there is correct, it works via LAN though. Also, I'm not able to ping myself with 127.0.0.1. I'm sorry to say it but I don't think I can stand this shitness for much longer. Although it's much much faster than Windows it's useless since i can't download any libraries for development. If anyone has any experience with this, even indirect, please leave your answer or comment thx

  • Troubleshoot dropped wireless connections

    - by Jack
    I was recently hired in the IT department of a small company (~180 users) and one of the issues that people have been complaining about is having their wi-fi connections drop during meetings. The company is using an HP ProCurve Wireless LAN with 10 APs and a controller unit located in the server room. I don't have any experience troubleshooting WLAN in a multi-AP environment, so I'm trying to at least gather information using free or cheap tools. I did a basic site survey using the free version of Ekahau HeatMapper and discovered the following in one of the conference rooms that has been a problem. The program picked up three access points (plus a bunch of others with much lower signals that were out of range): AP 1: SSID: "Unknown SSID" - Signal strength: -48 dBm - -40 dBm. Channel: 2 AP 2: SSID "CompanyMain" - Signal strength: -35 dBm or greater. Channel: 2. Security: WEP (This is the main SSID for the company's WLAN.) AP 3: SSID: "CompanyGuest" - Signal strength: -40 dBm - -35 dBm. Channel: 2. Security: WPA2 (This SSID is the company's "guest" WLAN, which was setup to allow Internet access, but prevent network access.) Is there anything that you see that is clearly a problem from the above? I'm assuming that the unknown SSID might be a big problem, and that it is an AP from a neighboring office that is causing interference. Does that seem likely? Also, regarding channel, should we try changing the channels of our APs to avoid interference with that unknown SSID? (Since everything seems to be on Channel 2?) Should our APs be on different channels? In other words, should the CompanyMain and CompanyGuest APs be on different channels? Finally, any recommendations for free/cheap tools to help me figure this out, and/or a good methodology to follow? Thanks in advance for any help. Jack

  • Is browser based wireless authentication secure?

    - by johnnyb10
    Our wireless network previously used a preshared WPA/WPA2 key for guest access, which allows them access to the Internet. (Our employee access uses 802.1x authentication). We just had a wireless consultant come in to fix various wireless issues we had; one of the things he wound up doing was changing our guest access to HTML-based instead of the preshared key. So now that guest SSID is open (instead of using WPA) and users are presented with a browser-based login screen before they can get on the Internet. My question is: Is this an acceptable method from a security standpoint? I would assume that having an open network is necessarily a bad idea, but the consultant said that the traffic is still using PEAP, so it's secure. I didn't get a chance to question him further on this because we ran late and a bunch of other things came up. Please let me know what you think about the advantages/disadvantages of using HTML-based wireless authentication as opposed to using a preshared WPA key. Thanks...

  • Bad ways to secure wireless network.

    - by Moshe
    I was wondering if anybody had any thoughts on this, as I recently saw a Verizon DSL network set up where the WEP key was the last 8 characters of the router's MAC address. (It's bad enough that hey were using WEP in the first place...)

  • Dynamic DNS Updates with Wireless and Wired interfaces

    - by Phaedrus
    We have offices full of Windows & Mac users who obtain IP addresses from a Windows DHCP server, which in turn updates Dynamic DNS entries. We are noticing major inconsistencies with the entries, and have found that the problem is occurring more on Macs than on windows, and even more when users are frequently switching from wired to wireless adapter, which makes sense, as this sequence occurs: User enables wired adapter and registers Proper DNS User enables wireless adapter and registers 2nd proper DNS entry user switches off wireless manually and 2nd entry remains improperly until scavenge. Our help desk folks rely heavily (maybe more than they should) on the dynamic entries as part of their business process. For example, the user submits a help desk ticket, and the staff member expects to be able to remote desktop to their machine by hostname, which is hyperlinked in the helpdesk ticketing app. We have implemented multiple solutions & band-aids to different symptoms of the problems such as: Using DNS Reservations for Macintosh PCs Using DNS Scavenging to remove old records Switching from a Cisco DHCP server to the Windows DHCP Server But no matter what we do, it seems impossible to maintain perfect records. Has anyone encountered this problem before? What is industry best practice? Comments & Suggestions are much appreciated, /P

  • Why is Internet access and Wi-Fi always so terrible at large tech conferences?

    - by Joel Spolsky
    Every tech conference I've ever been to, and I've been to a lot, has had absolutely abysmal Wi-Fi and Internet access. Sometimes it's the DHCP server running out of addresses. Sometimes the backhaul is clearly inadequate. Sometimes there's one router for a ballroom with 3000 people. But it's always SOMETHING. It never works. What are some of the best practices for conference organizers? What questions should they ask the conference venue or ISP to know, in advance, if the Wi-Fi is going to work? What are the most common causes of crappy Wi-Fi at conferences? Are they avoidable, or is Wi-Fi simply not an adequate technology for large conferences?

  • disable RADIUS for Cisco 2500 wireless controller

    - by Tim Vaughan
    I have a Cisco 2500 wireless controller and four lightweight access points. I want to use the controller to manage a wireless network secured by WPA only, without using RADIUS or anything else. We'll handle the authentication using a captive portal behind the access points. However, it seems like the controller's default security policy requires a RADIUS server and I can't find out how to switch the policy off. The documentation assumes I'm in an environment which needs heavy-duty security and the use case is actually a small charity/business with much less stringent security requirements. How do I disable the complicated security policy and instead run a simple one that just uses WPA?

  • Managing a wireless internet connection

    - by cornjuliox
    I've just recently purchased a USB wi-fi adapter and have been using the software (for Windows XP) that comes with it to search for and connect to networks, but it's really quite slow and featureless. Are there free/OSS alternatives for Windows XP that can I can replace it with? Preferably something that can, in addition to connecting/searching for wireless networks, display stats like signal strength and transfer speeds on graphs so I can better monitor the quality of my connection?

  • Windows doesn't get access to internet though linux easily does

    - by flashnik
    We have a very interesting problem. The network is configured in this way: internet is connected to Trendnet switch TS DHCP server at 192.168.0.1 running on Ubuntu (S) is connected to internet switch DNS is also configured on 192.168.0.1 on S D-Link Wi-Fi boosters are connected to switch TS PCs use D-Link PCI-E Wi-Fi cards to get access to network PCs have both Ubuntu and Windows 7 There are about 40 PCs. When PC is booted to Ubuntu it easily gets access to internet. But when it's booted to Windows 7, it gets a valid IP-address, but doesn't get access to internet. The address, mask, DNS, GW-address are totally the same as when it's booted under Ubuntu. The S is reacheble and pingable. Sometimes when we are lucky the PC gets access to Internet, but after rebooting it can lose it. When PC under Windows has access, it has totally the same settings as when it doesn't. What can be done? UPDATE I shared a dropbox with 2 captures of traffic. Ping.pcap is a capture of pinging 8.8.8.8. And google-browser.pcap is a capture of opening a google.com in a browser, both of them are in tcpdump formats and made by Wireshark on Win PC. The MAC of Win PC ends on b7:63 and IP is 192.168.0.130. UPDATE2 This is ifconfig output from Ubuntu Server eth0 Link encap:Ethernet HWaddr 00:1e:67:13:d5:8d inet addr:193.200.211.74 Bcast:193.200.211.78 Mask:255.255.255.0 inet6 addr: fe80::21e:67ff:fe13:d58d/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:196284 errors:0 dropped:44 overruns:0 frame:0 TX packets:190682 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:158032255 (158.0 MB) TX bytes:156441225 (156.4 MB) Interrupt:19 Memory:c1400000-c1420000 eth0:2 Link encap:Ethernet HWaddr 00:1e:67:13:d5:8d inet addr:192.168.0.1 Bcast:192.168.0.254 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:19 Memory:c1400000-c1420000 eth1 Link encap:Ethernet HWaddr 00:1e:67:13:d5:8c 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:16 Memory:c1300000-c1320000 nslookup from Win results in DNS request timeout, nbtstat in 'not found'.

  • How to create a separated network to customers only?

    - by Valter Henrique
    I work in a company where we have a network ethernet and wi-fi, we would like to create a network where our customers could access our network but don't have access to our computer network. This access would be internet only, nothing more. The customers will not see our computers and the files that we share in our network. I have two routers, how can I do this ? A Cisco Linksys Wireless-N Broadband Router WRT160N V3 and a Netgear Wireless G Router WGR614 v9 and about firewalls there´s only windows firewalls in each computer by default.

  • 2nd/3rd version of wireless network appears

    - by neildeadman
    I replaced an old SpeedTouch ADSL router with a Netgear DG384 that I have and whilst doing so decided to change the wireless password. For this question assume my wireless network SSID is DeddersHome. On my netbook and macbook pro (running Win7) it won't connect to the Internet. When I hover over the tray icon for wireless it says "DeddersHome 2" and "DeddersHome 3" have no internet connection. What are these additional wireless networks? I can't see them in the wireless network list on any wireless device I have. Wired connections and wireless through my iPhone work fine. I saw this before with the SpeedTouch, but it just went away!! I also have one Apple AirPort Express connected to the wireless network which my Xbox is connected to (wired). This all worked before... I am going to remove AirPort to see if it is this causing the problem, but thought I'd ask the question to give it time for an answer whilst I continue to search. Cheers

  • Failure to obtain IP with ARP over Wi-Fi with personal Wi-Fi router in client mode

    - by axk
    I'm trying to connect a Samsung TV to the Internet using a TL-MR3020 personal wireless router in client mode. The TV fails to connect to the network. It sees the ethernet cable connected though. Here's my network topology: Here's what I've captured with Wireshark filtering for ARP (eth.type == 0x0806): It appears the TV fails to get the IP of the gateway (DSL modem/router) for some reason. One thing I've noticed is that the source MAC for the ARP requests coming from the TV is the MAC of the Portable wireless router (that is cd:89:00), not the TV itself and the modem sends the responses to that MAC (I'm not an expert and don't know if its okay or it may make the TV fail to get the requested IP). Also I'm able to ping the TV from the DSL router (through the telnet interface) and the router has an entry in its MAC table for the TV's IP with the Portable wireless router's MAC (that is cd:89:00). If I'm able to ping the TV I suppose it should know the router's MAC to respond to the ping, but then why these continuous ARP requests... I've also tried to connect my desktop trough this Portable wireless router the same way I'm trying to connect the TV and it works fine, I can set the DSL Modem's IP as the default gateway on the desktop's NIC and connect to the Internet. The TV can connect to the Internet when connected to the DSL Router with a wired connection. Any suggestions on what may be the cause of the problem / how to further debug it are welcome. Thanks!

  • MS Vista taking too long to identify Wi-Fi connection [closed]

    - by I_M_SUPER_USER
    I with few of my flat-mates share internet connection by using ASL cable into one laptop and then making Adhoc private network so that we all can enjoy internet connectivity. It all worked wonderful few initial days, but now my MS vista is taking much time to identify that adhoc network and it though I am connected to my friend, it takes 5-10 minutes untill I use internet.

  • Implementing an isolated guest WLAN via IPSec VPN on Windows

    - by sysadmin1138
    We are attempting to set up a guest WLAN network that is isolated from the rest of our network. This is proving difficult due to a couple of technical reasons. My first choice was to use a separate VLAN, on which our Firewall's handy WLAN port would handle DHCP, DNS and the network isolation we need. Unfortunately, due to the fact that our main office and our Internet connection itself are in different locations connected by way of a Metro Ethernet connection, I'm at the mercy of our ISP for VLAN transit. They won't pass a second VLAN between our two sites. And my hardware doesn't support 802.1ad "Q-in-Q", which would also solve this problem. So I can't use the VLAN method for isolation. At least not without spending money. As our Firewall can handle IPSec site-to-site VPN connections, I hope it is possible to connect a Server 2008R2 (standard) server I have in the office location to the WLAN and provide gateway services to the firewall. Thusly: Unfortunately, I don't know if it is possible to connect the two this way. The firewall has a pretty flexible IPSec/L2TP implementation (I've used it to connect iPads in the wild), but is neither Kerberized or supports NTLM. The Connection Security Rules view on the Windows server seems to get close to what I think needs to be done, but I'm failing on figuring out how to get it to do what I need it to do. Is this even possible, or do I need to pursue alternate solution?
