Connection Failed: Could not contact wireless access point

[Rukkas]

So i have tried everything. I'm relatively new to Linux. I have used Ubuntu 10.04 a while ago. But have been on a windows box for some time and forgot a lot about it. This time, i have Backtrack 5 installed on a laptop with intel PRO/Wireless 3945 [golan]. So here is my problem. I am able to See networks in wicd client, and also when i run airodump-ng. Airmon-ng shows my wlan0 interface, and i can crack wep just fine. But when i try and connect to a cracked network, or even my own, it tells me can not obtain IP address. So i changed to static and input the information known for my network. Assigned an IP within the scope, and then it tells me that "connection Failed: Could not contact the wireless access point" I've checked with /var/logs/wicd/wicd.logs and its returning that Connection failed: Failed to ping the access point. exiting connection thread, sending connection attempt result association_failed. I am at a stand still. I dont know waht else to do. Can someone help? thanks in advance for all who post positive replies.

I am having the same issue on my Vostro 1510 laptop. I wasn't able to get it to do anything at all with wicd 1.7. I saw some articles about the same issue that suggested I downgrade to 1.6.2.2. I did that and was able to get further than I had before. But then it started telling me it couldn't get an IP. If I put in a static IP it tells me it can't connect to the access point.

Here's what the logs are showing me:

It's saying DHCP failed. I'm getting it no problem when booted into windows 7. I've reset everything on my wireless router and tried multiple fixes from around the web. Has anyone else run into this? I'm kind of at a loss...

Seems like backtrack 5.1 has multiple issues with WLAN configuration.

installing network-manager instead of WICD normally fixes this.
The problem with the kernel flag that disallows iwtools and so on remains. I dunno exactly how to fix this, but I think reinstalling the kernel without that flag should do the job. Though I dont know exactly how to do this.

Maybe someone has advices here?

It seems like it's just broadcom issues. I plugged in the Alfa card that just arrived and no issues at all. Works like a charm. Going to disable the broadcom in Bios and forget it's even there.

almightyzappa,

what alfa card did you go with? I assume it's a pci based card...

[almightyzappa]

It's one of the USB ones recommended on the forums here and there. It's the ALFA AWUS036NH. Got it on amazon for 32 and change. Works like a charm.

cool, thanks for the info, i think i am currently using an old belkin f5d7000 v8 with the ath5k driver, and the alfa 5dbi 10' antenna extender in my tower but it doesn't support packet injection (as far as I can find) so trying to find a new one that works good with BT5 x64
