I have been having internet problems the last few weeks on my PC (every other device in my house works fine), I was getting really slow speeds and was getting a lot of twitter buffering. Recently as in today, my internet has gotten really bad and I decided to do some troubleshooting. I tried updating drivers, uninstalling then reinstalling, turning my router off and on, and some other small things. After trying to get it fixed it got even worse and the computer started connecting then disconnecting than connecting then disconnecting etc, it kept doing this until I unplugged the ethernet cable (this is now fixed). I decide to use the WIFI to do stuff while I tried to fix it and what I noticed was that on Wifi I got 550 Mbps while on ethernet I got 93 Mbps and that doesn't sound right. The cable is a Cat 6a cable. I bought it like a year ago so it's not that old. So any help on why this could be would be appreciated. PS. here is some important info, I pay for 1 Gbps internet speed, my router is just at most 12 ft away from my PC.
