My computer can't download

Hi,

I can't download files with my computer for some reason, I can get around on the internet fine though. I've got a cable modem with 3 mbs speed. I checked to make sure that downloads were turned on in IE security options and it was. I aslo checked another browser (Opera) and it can't download files either. Then I thought it could be a virus or the OS (which is windows xp home edition) so I used a utility to turn my entire HD to 0's and then reinstalled windows, still can't download. I thought maybe it was the network card or the cable modem or the connection point, so I put the network card in another computer and used the same modem and the same connection to the internet and it worked fine.

So now I'm at a loss, I've narrowed it down to not being the OS, virus, network card, internet connection, cable modem, web browser. Please help.


Thanks in advance

These settings are not written in "stone" there is variability depending on the computer other setting. So try few setting and measure your Download for each setting.

In addition, in case a person has a Router the Router's MTU if set differently can affect the general MTU.

Is there a firewall built into windows xp that I could disable? Or is there a registry edit anyone knows about?
