I've been using Limewire and other file sharing programs for a while now. I'l always recieved good speeds both at work and home. Up to 60KBps download. Which is my max.

Lately, both at home n work, I can't seem to do any better than 4KBps??? And not just limewire, most other file sharing programs too. I use a router at work and at home the computer I use is networked to another computer via crossover cable. Now the main computer connected to the Internet at home gets full speed downloads, but the networked computer is just as bad as my comp in the office. What could the problem be???

All the comps mentioned above have WinXP SP2 installed.
