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 coursed 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). The network is not hidden.
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?
