- I am not tech savvy, so please give me explicit instructions if you have a solution.
- This problem has gotten progressively worse.
Here goes: I've been using Ubuntu 12.04 with a D-Link wireless router for over a year without problems. The problem began a few weeks ago. It would not connect to the router, though it recognized the network. I could usually solve this by rebooting the router. That is not working any more. Now, most of the time I open Ubuntu it will not connect at all (I have dual-boot with Windows and an iPad and in most cases they can still connect). Yesterday, the wireless worked on one occasion, but not on two others. Today it is not working at all and when I try a wired connection that is not working either. Please help!

BTW, I have recently come upon some evidence that the problem might be with the router. Strange that only my Ubuntu operating system doesn't connect regularly, but my neighboir told me that he has had some trouble connecting with his Mac, though that is usually solved simply by rebooting the router. Lemme know if you have any insights.
