amped wireless will just make it worse.
What you want is to find out what aps are in your area, find out what channels they use and get one that uses supports a channel they dont. You wont have hope on 2.4Ghz but on 5Ghz different routers can support different channels. So using one which supports a channel that another doesnt is one way.
Use software to see what channels they use too as not all may be 5Ghz.
thats not so bad. 2.4Ghz is just for range and compatibility. 5Ghz has so much room that you dont need to worry about which channel. triple channel APs support the upper band of 5Ghz that many routers dont. Dont bother trying channel 13 on 2.4Ghz as many clients dont support it.
any 5Ghz AC capable router like the AC1900 class or better. your area isnt really crowded.
