I have century link and have an airport express. I have it connected to the century link router and have the wi-fi turned off on that. I have two networks one regular band and one 5ghz. The speeds are good around 40 and 5. Youtube sometimes is horrible or videos. sometimes wont load at all. Sometimes its quick but still isn't anywhere close to as fast as my lte if i use my phone which is almost instant. Does anybody know the correct settings for the airport extreme? Anything i can do to improve consistency and speed?
