Alright, I'm just going to cut to the chase: I have an Intel(R) WiFi Link 5100 AGN WiFi card in my laptop. I've had this laptop for about 4 years now, and about 1 week ago, I started having this problem... Every time I turn on my computer, I connect to my network with no problem. But, maybe 30 minutes later (This actually varies. Sometimes 30 min., sometimes 3 hours), my WiFi card disconnects, and no matter what I do (restart the router, restart the modem, disable the security on the router, etc.), my laptop will not ever reconnect back to the network. Of course, if I restart the laptop, it will do the same thing. (Connect, time passes, permanently disconnect). Every time I try connecting to my network after that, it keeps telling me "Windows was unable to connect to *network*", and the Network Diagnostic tells me, "Problem with wireless adapter or access point". All other devices (other laptops/computers, iPhones, iPods, 3/DS', etc.), connect to the network, just fine. So, clearly, it's a problem with the wireless adapter, which is my WiFi card. And it's wired into the motherboard, so I can't just take it out and replace it. I've tried updating the drivers to my WiFi card, but Device Manager tells me I have the most up-to-date drivers. When I tried installing the latest drivers from Intel's website and Dell's website, Intel's tells me it's not compatible with my system(?), while Dell's says I'm up-to-date, and cancels the update. So, not a whole lot I can do there... Does anyone have any clue as to what the problem is? I've had to rely on this crappy Linksys WiFi adapter, which has a weak signal to my network from my room, and it cuts out every once in a while. My WiFi card use to connect to the network, full bars and everything, no problem... of course, until now. If the WiFi card itself burned out, then it shouldn't be detecting any networks at all, correct? It is detecting my network, and all other nearby networks, so it can't be completely broken... What the hell is wrong with it?
