Connection problem

[plasticdubs]

Hi, I have a cable modem and my computer is connected to the router. It shows that it is connected and I can load up some websites but when I try to do a search or anything it wont work most of the time. Also when I try to get on AIM I can sign on but it never loads up my buddylist and will eventually just disconnect me. Lastly when I try and play a game online, I can load up the game and everything but once I log in, it will just disconnect me within a few seconds Something might have happened through command prompt or something? I don't know, my friend had tried to mess around with things before when I had wireless and now that I am directly connected to the router this is happening. Although when I change back to wireless everything will run fine. Whats going on?? I don't know much of anything about computers so any suggestions of how to fix it would be great. Thanks.

have you tried disconnecting from the wireless and just using cable? what happens? i've heard strange things can happen when both are connected.

did you try switching the router port for the hard connection? pull the physical plug on everything then restarting it all?
