Background I live in an apartment. The apartment complex has an exclusive contract with a 3rd party vendor with AT&T as the internet provider. Each apartment building has a room that has the main router that is inaccessible by the tenants. All I do is plug an ethernet cable into the data line that is in the apartment, and plug other end of cable into my AirPort Extreme. I do a speed test and the results depend on the time of day. In the mornings my WiFi is usually anywhere from 14Mbps to 25Mbps. At night it might be 7Mbps. I have an iPad Pro, iPad 2, 2 iPhones, Apple TV, and my wife’s work phone all connected to our WiFi. I went to the AT&T store the other day to upgrade my son’s phone and they let me know that if I get my internet through them that it would be cheaper. I explained the situation at the apartment. They explained that I could do a self install. They simply send me the router and I plug it into my data line, and then cancel my internet through the 3rd party vendor. I asked the possible speed I could get. They replied 6Mbps. Sucks living in a rural town! So I asked the sales person how I was getting the other speeds. They had no idea, but that I could test with the router they send to make sure it isn’t any slower. So I said ok. I haven’t received the router yet. Like most people, I assume, I’m trying to figure out the best way for my internet to be set up for optimum speed and reliability. Honestly, the speed is fine for what me and my family do on the internet on our phones and iPad. What I wonder is what’s the best way for my Apple TV to be set up. It has always been used on WiFi, but there are times at night that it is buffering and that is annoying. Not only that, my wife and I want a 4K TV and 4K Apple TV, but I’m not sure our internet speed is fast enough. I know that a wired connection is best, or at least that’s what I’ve been reading. So I went and bought Netgear Powerline 1000. I connected everything, but I don’t see hardly any difference from my Apple TV connection to my 5Ghz channel on Aiport Extreme. Could that be because I’ve only plugged into my AirPort Extreme which is simply the WiFi router, and not the main router that I don’t have access to? Or does it even matter? Is the new router AT&T sends that plugs into my data line in apartment and will be the primary router going to make a difference with the use of the Powerline adapters since one will be plugged into primary router? Also, considering my situation, what would be some advice you might give on setting up my network in my apartment?
