So, I've run into a very strange problem with my home wireless network. Previously, at seemingly random times, the router seemed to disconnect all wireless hosts and cause all of the wired hosts to have a "limited connection" according to windows. In order to fix this, I had to unplug all of the wired hosts from the router, unplug the modem from the router, and power cycle the router. This seemed to solve the problem for a while until the exact same thing happened a day later and I had to go through the same process again.

That's where I noticed something weird happening. There was one wireless host (a Windows Vista laptop) that seemed to be causing the router to disconnect the other hosts whenever it connected. When this happened, only that laptop was able to use the wireless from the router. When this happened, I disconnected it from the wireless (by disabling the wireless adapter) then reconnected it (by re-enabling it) and now it, like the other hosts, couldn't connect.

I've never really seen anything this strange happen on our network before. So, I restored the router to factory settings and the problem seems to have vanished except one crucial problem. There's another host (a Windows 7 laptop) that was perfectly able to connect before all of the router issues and even in between the crashing and power-cycling events but now says its connected and says it's able to reach the Internet, but all requests time out. In any browser I've tried, the tab says connecting to [site]... for a solid minute and then tells me the request timed out. When I try to ping google.com in cmd it also says request timed out.

In frustration, I booted into a dual-boot Ubuntu installation on the Windows 7 host and the connection works fine, to my surprise, as ubuntu is where I am now typing this rather long question.

• I haven't looked through the event log in windows but will post anything I find in an edit
• I haven't tried connecting (in Windows 7) to any other wireless network, since
• The fact that it works in Ubuntu suggests its Windows and not the router but I didn't change any wireless settings in windows before it being able to reach the Internet and not.

Does anyone have any clue what could have happened. I opened to buying another router as this one is almost a year old :) but I would like to know whats going on here.

Thanks in Advance!

P.S. Sorry for how long my question is, I'm a little anxious (:
