I've noticed that as of about 2 months ago, transferring files across any LAN to or from my computer is excruciatingly slow. Transferring files to or from my main computer to any other computer on my home gigabit LAN, I get transfer rates of around 2-3 Bytes/sec. So slow that it takes several minutes to transfer just a few kilobytes. I really cannot figure out what is causing this. Does anyone know why this might be happening? Also, this only happens when my main computer is involved in the transfer. Transfers across my LAN involving any other computers work normally, as do Internet transfers. And it happens everywhere. Even when my PC is hooked up to other LANs.
