Bizzare Infuriating Network Problem: Slow Upload


Posts: 161   +1
I've read all I can about this online, and tried everything I've come across. Since upgrading my internet (same ISP) the upload on my computer (not any others on the network).

It ranges from 0.2 megabits to 1. If I boot into linux I get 3, but that's far from the 8 megabits the other computers on the network get.

But the strange thing is, the problem seems to affect only certain programs. My browsers are affected as the internet tests I do are from the browser. OBS (streaming software) will not upload more then 0.2 megabits (about 20k). However utorrent can completely max out my upload.

I've tried stopping the WMI service and I have no traffic shaping software installed.

Here are my specs:

I figured it out, the Killer NIC on my Z87GD65 mobo was not compatible with NetLimiter. Uninstalling it fixed the problem :)

Good to hear you got it fixed. Be careful about torrenting though, ISPs will throttle your internet if you do it too much.
