I have a fresh install of windows 10, updated drivers, reinstalled drivers, latest bios, and I'm getting speeds anywhere from 16-30 mbps on a 120mbps connection. My wife's alienware, sitting equidistant from the router and near me gets the full speeds. I've adjusted wifi settings, tried both 2.4 and 5g networks, disabled auto tuning, rebooted modem and router, verified all my router settings as normal, disabled QOS on both router and laptop, and still same issues.
I adjusted all the power settings for maximum performance as well. After all of that my speeds were in the 30-60 range, still about half of what it should be. My upload keeps spiking over 100mbps which is bizare, but it's only happening on this one PC.
Wireless adapter was disabled when I booted into safemode with networking so I wasn't able to test that way, and doing diag startup with MSCONFIG disabled my network adapter entirely.
Is there something I've missed? I thought it was my network but every other device on it gets 100mb+. I'd just like to reliably get 80+ on this thing.
