Hi, i dont have my usual tech guy anymore. Ive got a 6yr old self* build that is having an odd issue. I have to use a WPS to connect to the internet because my router is on the other side of the house. It has been working fine but recently im getting less than 1.0 upload and download speed. I replaced the WPS (netgear nighthawk) and it went back up to 100 for a second but it shot right back down. What else can effect my internet? Ive checked for updates and ran the antivirus thats included with windows but im stuck now. Any help is appreciated. I can post the parts my computer has if it helps. Thanks!
