In what universe is wifi a substitute for a proper wired network, for serious bandwidth and reliability? I've got so many other wifi routers polluting the radio waves that I can't stream Netflix on my TV that is 15 feet away from the router.
It's so bad that I bought a 50' ethernet cable and tacked it up along the ceiling from the router to a switch by my TV to create a redneck ethernet network. Works beautifully - well, not beautifully in the aesthetic sense, but it gets the job done well.
I had to do this too. There are at least 30 networks in range of my apartment at all times, so 2.4 Ghz WiFi is useless in the evenings. I'm glad there are few 5 Ghz networks here so my newer devices are still usable.
5GHz has horrible range and wall penetration (by design), so it can't really get as cluttered as 2.4GHz which has decent out of line-of-sight performance
