I found this extremely helpful. The suggestion from Gwalk to disable QoS worked, as it appears that things are loading much faster. I was also able to stream the video of the speed tests in HD. Though this may have eaten up data, it was worth to test. Thanks for the help!
Sites such as mediafire still do not work at all. Downloads from many sites still fail before they start. Also, my main computer still has trouble connecting to the internet while connected wirelessly or wired to the modem. I have made sure the Qualcomm Atheros drivers are working properly, so it should be able to connect just fine. As a matter of fact, it connects perfectly when using someone else's internet. Sure pages load faster now, but what good is download speed when downloads constantly fail?
