I am having a bit of trouble with my Internet connection. I am able to use any sort of application that requires an internet connection (games/skype) without any problems, but when it comes to using a web browser, web pages load really slowly or sometimes not at all. When I restart the network card or ipconfig /release and ipconfig /renew, web pages load at a decent speed, but about 2 minutes later, it goes back to its slow loading. I am running off of a wireless connection, a 2.4 ghz internal card made by Rosewill. Also, this computer is one that I have recently built and is brand new. From this, I find it unlikely to be malware/viruses. I also have 3 other computers running just fine off of the same router, so I do know it is a single computer issue.
I know this problem could be caused by many different things, but if someone could help me, I would be grateful.
