Hi, I have what seems to be a very weird problem going on. My roommate and I have a LAN set up for our three computers (his laptop, my netbook, and my desktop, all Windows 7) on a D-Link DI524 Wireless 802.11g router which is connected to an Arris modem, model # CM550A. His laptop and my netbook connect wirelessly, and my desktop connects via an Ethernet cable which has to be extended using a switch and another Ethernet cable because my desktop is so far away from the router.
Anyway, here's the problem. I'll have normal network access and access to the Internet, with no indications of any problems, and the connection will just randomly drop. The network icon in the taskbar will have the yellow exclamation mark, and when I run the troubleshooter it gives me these two errors: "'Local Area Connection' doesn't have a valid IP configuration," and "The default gateway is not available." It attempts resetting the "Local Area Connection" adapter, but this doesn't help. Nothing I can think to do via software seems to fix anything. However, pulling the power on the router, waiting a few seconds, and then plugging it back in fixes the problem. Unfortunately, this only works temporarily, and the problem will pop up again in maybe the next fifteen minutes, or it may be an entire week before it happens again, it seems totally random.
My roommate claims that the loss of connection doesn't happen to his laptop, but I know for a fact that it happens to both my desktop and my netbook. This makes me think it's possibly something that I've done with the settings, but I can't think of anything that I changed, let alone something that would cause this to happen. Any help would be greatly appreciated, and if anyone needs more info or specs, I'll be happy to oblige.
