I'm having a very strange home network problem. I have 3 computers, all hooked up to my Linksys 4 port Router and all using my fiber obtic internet connection. All computers have Windows XP Professional installed and all network settings are basically the same for each computer. My problem is I am able to download perfectly fine from any computer, but when uploading to any site, I have no problem with the computer I use most but for the other 2 it begins to upload the file and slowly dies out and eventually hitting 0.0k/sec. This problem also effects sharing between my pc's in that I cannot transfer a file from the 2 pc's to my pc. I've tested the cables and the nic cards but they appear fine. Any help would be greatly appreciated!!!
