I am technologically inept and would like some help from the board experts. I am slowly having more and more home WiFi issues (buffer and slow loading times). two story house with 3 kids so have multiple TVs, Xboxes and devices. No cable just streaming TVs. Right now I am using spectrum internet with their router (techicolor TC8717T) and my WiFi (netgear N600) which is 10 years old now and is located in the basement. Is my problem with Spectrum (never trusted them), the router or the WiFi. If its router and WiFi what should I get? Thanks in advance.
