I've never run into a problem like this, and I'm fairly computer illiterate, so I'm not sure what to do.
I went on Thanksgiving break from school and shut off my computer. Everything was working normally up until that point. Upon returning, I turned on my computer and when I opened Firefox, all the pages took a very long time to load.
The odd thing about this is that when I hovered my mouse over my wireless connection when no Internet-using programs (AIM or Firefox) were open, the connection speed said 11.0 Mbps, which is what it normally is, and nothing was wrong. The minute I opened up Firefox, I hovered my cursor over the connection icon and the speed said 2.0 Mbps. I haven't the slightest idea why this is happening, but it's affecting the computer of the one other person on my network that uses Firefox. The other three people on the network use Internet Explorer.
I know it seems like an odd problem, but any help would be greatly appreciated.
PS: I've also run Spybot and Ad-Aware and restarted, and nothing works.
My bad. I forgot to clarify that the people using Internet Explorer aren't experiencing any problems with their Internet. Two of them are connected in through a land lines and one is using a wireless ethernet card. It's enough to make me suspect Firefox, but I don't really know where to look.
