Got that half speed thing going on. Not sure what to do.

So I'm primarily running off of WiFi, 802.11 AC. Status window shows a potential speed of 867Mbs.

I've got Windows Home, 64 bit.

Previously my internet was 300Mbs down. When I did any kind of speed test I'd get around 150. Sometimes a bit higher.

I blocked pretty much all telemetry, reduced windows update bandwidth to 5%, disabled the windows update service, reset my tcp/ip stack, changed to a faster DNS server; pretty much everything I could find on google or bing.

​

Then I started getting around 200 consistently. Disabling tray applications and what-not had minimal effect so I just let them run (it's stuff like Adobe CC Launcher and Autodesk Launcher, need them most of the time anyway.

​

Fast forward and my ISP doubled my speed to 600. So now Windows is getting close to 300, sometimes a bit over and I"m here scratching my head trying to figure out what setting I'm missing that's cutting my download speed nearly in half.

​

My phone will speed test at 540 - 580. My old Windows7 Laptop will pull in the full 600 all the time.

​

I've got some Ethernet cable (cat6) on the way from Amazon; I'll give that a shot but if that doesn't work is there anything I should try before I just format the whole system and start from scratch? A setting or option that people commonly miss?

One final thing I should note; I put Ubuntu on another drive and then ran it on this same hardware; It pulled in 600 over wifi no problem so It's something in windows. having a hell of a time figuring out what though. Even using the resource monitor. Very strange.

Edit: Decided to do a full format and restart due to so many strange issues popping up. Thanks for trying to help, you're all awesome.
