Hi guys, I'm very frustrated and disappointed because I can't make my broadcom 4312 work with b43...
It used to work on older ubuntu kernels, but not now, with newer ubuntu releases and BackBox 3.05.
After a fresh BackBox install, my wireless card wasn't recognized at all, even after installing the b43 lpphy firmware installer...
After many trials and errors, I solved this (and a scanning problem) by upgrading to a newer kernel (3.5) which seems to work best among other versions, as I read on this forum ( newbielink:http://forum.backbox.org/hardware-support/dell-inspiron-e1505-bcm4311-problems-no-wireless/15/ [nonactive]).
But now there's a last annoying problem, which is giving me headache:
I can connect to my AP succesfully, and at first the internet connection works ok, but just for some minutes.
After, even if I'm still connected to my AP, the webbrowser or the terminal (ping command for example) cannot contact the requested server, behaving like I have no connection..
After a lot of time and randomly, it seems to start working again, but for a little time, and then again and again...
I don't know how to understand and solve this problem, can anyone help?
Thank you!
