Ubuntu – Ubuntu 12.04, can’t find the home wifi network

12.04broadcomwireless

I've tried several solutions I found on the web, but didn't manage to solve a problem.

Since today my laptop won't find my WiFi network, but neighbours' networks are suggested.
Another laptop with U12.04 does find one.

What do I do?

I've Dell Latitude-E4310,
