Lately my wifi will randomly crash, making using the internet hell. I bought a new modem and all the ethernet connected devices are running even faster. My wi-fi is pretty old 5-8 years, and I was thinking of buying a new one. I have spending cap about $150 give or take 20 bucks. There seems to be all these compatibility issues that I have to look out for so I am looking for pro advice. Thanks guys. What should I buy?
