Hello, I have karmic on a HP pavilion dv5 with a broadcom bcm4312. I can connect unprotected networks but when I connect to a wpa or a wep network, internet doesn't work. It's not a dns problem because I've already tried to ping web directions without response but I can ping my router and access its configuration.

I've tried using wicd, b43-fwcutter, compiling source from restricted drivers but nothing works.. When I use the broadcom STA driver it list all the networks and I can connect but I only get internet with unprotected ones. I also can connect through ethernet.

I've searched a lot but there are many problems with broadcom cards, I've tried everything but maybe you could help me with my problem.

This is what lshw -C network lists:

Go to Synaptic Packagemanager (System>Administration>Synaptic), search for WPA, and WEP... Look wich codecs are available, and if they are installed...

If not, mark them for installation!

Did you check the Hardware Drivers? (System>Administration>Hardware Drivers), Check there if you'll need a specific driver for your adapter. And if so, Activate that driver!

Yes, I said that I have restricted drivers from broadcom activated, and with them I can connect networks, but if it's protected I can't manage to connect to the internet. The network manager displays it's connected but it doesnt loads anything and doesnt pings any ip.

I have used this tip in 8.10 and will try it in 9.10 when I upgrade to it. It's howto to manually install binary drivers provided by broadcomm itself.
