Ubuntu – How to connect to the own WiFi using Broadcom STA drivers

12.04asusbroadcomdriverswireless

I'm trying hard to switch to Linux from Windows because of my engineering project. Unfortunately, everything is against that change!

  1. Before I have installed Broadcom STA proprietary drivers, I was seeing on NetworkManager and nm-applet only local radio-internet-access networks.
  2. After I installed Broadcom STA, I see my neighbor's wireless network (channel 11, WEP)
  3. Neither before nor after the installation is own wireless network available.

Computer: Asus Lamborghini VX6
Ubuntu: 12.04 LTS 64-bit
Router: ASUS N55U (A1) with newest AsusWRT firmware
Network: Channel 5 (tried also 10 and 11, both on 20 and 40MHz bands), WPA2 Personal, 2,4 + 5 GHz (what is not very important, 'cause the wlan card in VX6 is only 2,4GHz).

Network works fine on Windows, also through D-Link repeater on the other floor. Unfortunately, same network is invisible to Ubuntu on same machine.

I have tried some combinations with other GUIs but it did not work. Are there any better drivers for Ubuntu?

I need that network badly, but I'm an Ubuntu newbie, so I don't know how to solve that problem. Please help.

Solved. Linux sux at wireless drivers, 'cause a lot of them has a limit of 11 channels out of 13 available. Moreover, even the network working in 40MHz mode, is ivisible, untill the first channel is under 5. 20MHz mode works from channel 1 to 11.

What's more amazing, is that my network, working on channel 5 now is recognised by Ubuntu as channel 7...

Question to drivers programmers and all that stuff: are you insane to make it different than in router that works on same type of kernel and is fully compatibile with e.g. Windows? -.-
