After upgrade to 12.04 wireless keeps dropping on BCM4312
- by Sheket
I know there are plenty of questions very similar to these, but I've tried practically everything and it still isn't working. Some solutions get the wireless connection working, but it goes very slow and drops after a few minutes. Then it won't reconnect and keeps asking for password.
Hope you can help me. Thanks in advance.
