Hi all,

My wireless stopped working after upgrading 11.10. It is able to detect wireless networks, but it fails to connect to mine despite the correct password is used. Occasionally, it manages to establish a connection, but then the connection is phony as it does not provide access to the internet.

I noticed there are a couple of solutions for "Broadcom" wireless hardware posted in this forum (which involve 're-installing' bcmwl-kernel-source, see here). I wonder if those solutions would work in my case as I have a different wireless hardware manufacturer (I have a TP-Link TL-WN821N wireless card and a TL-WR941ND router). Any help or comment would be much appreciated!


P.S. Interestingly, I just noticed that my neighbour's wireless network is not password protected, and my computer is able to connect to that and is able to access to the internet. But it just wouldn't connect to my password-protected network any how.... I am 100% certain I used the correct password


Many Many Many Thanks!
