So, I have a dlink 655 whose network is suddenly not showing up in ubuntu? I have just returned from a week of travelling (during which I used plenty of wifi on ubuntu), and on returning home, both win 7 (same computer) and phone can see the network just fine, and ubuntu can see 5 other networks, but my own is gone? I have of course tried restarting the router, to no avail. Right now I'm on one of the other networks, which works fine (but is of course pretty unsatisfactory).

I'm guessing some driver update in the past week (like a good boy I of course install all suggested updates) has messed something up? Any ideas for what to do?

Btw., I tried reinstalling the generic headers through

Code:
sudo apt-get install linux-headers-generic
sudo apt-get install --reinstall bcmwl-kernel-source
since that solved the problems when my wireless card didn't work at all. However, that gave me:

and that had no effect, neither after reinstalling. I must admit I don't know wat the last errors mean, but it seems I didn't break anything at least.

Anyone has any ideas for how to find my wifi again?
