So, got my new PC and plugged ethernet into the router. Now the WiFi is spotty and/or not even working for some devices (laptops/tablets/etc). My mom claims she was having issues yesterday morning and this morning when the cable wasn't even plugged into my PC. I also moved the router about 2 ft over and 1 ft up (from on top of their PC to ontop of the desk)
Router is a Cisco DPC3825
Any suggestion to fix the WiFi?
