Hey everyone,

I have been re-downloading some games on steam and it was taking a really long time, so I decided to run a speed test and see what kind of speeds I was getting. My DL speed is 30-35mbps, but my UL speed is around .5 mbps. My mobo is an Asus P8Z77-V Pro/Thunderbolt.

Just for grins, I booted up my old rig to see what it would get. It got the same 30-35mbps DL speed, but got 4-6mbps UL speed. This computer has an Asus M4A88TD-V Evo.

I checked the driver through device manager and it says it is up to date. I'm running Windows 7 Ultimate and it is all up to date as well. The only thing that I found that I could update is the BIOS. Is it possible that could fix it? Is this even a software issue or is there likely something wrong with my motherboard? If there is something that I am missing or any suggestions on how to fix it are much appreciated. Thanks in advance!
