Hi folks, I have an odd problem that I could use some help with.
I upgraded my LMDE installation to UP4, and things went reasonably well. Since I had recently bought a new HD (additional instead of replacement), I decided to do a new install on the new HD.
On my new install, however, I have problems with Wifi and Bluetooth. Bluetooth connects for about one to two seconds, and then drops (this is reproducible ad-nauseum). Wifi works (sort of), but never first (and rarely second or third) time. Generally, it will connect, but no traffic will be possible (pings don't work, etc.), and I have to disable and re-enable the hardware (software or hardware switch) at least once, generally two or three times. After that, the connection will be reasonably stable to an open (unsecured) AP. Connections to all the secured APs I have tried simply fail, reporting that authentication has failed (I haven't been able to test this exhaustively, though).
My first thought was that it sounds like a kernel and/or firmware issue, but I still have my old (upgraded) installation available, and none of these problems exist there, with the same kernel. I've also tried the latest Liquorix kernel (3.3.0-1), with the same results -- everything's fine on the upgraded installation, but the same problems exist on the new installation.
Can anyone offer me a suggestion or some advice for what to try next? It's most frustrating!
HW: Dell Precision m4600 laptop
Wireless: Centrino Ultimate-N 6300 (iwlwifi)
Thanks for any help which can be offered!
