Compatible network extenders for a C7000v2

[Ward27804]

I have a C7000v2 and I am having trouble getting consistent wifi signal to the rear of my house. Wanting some suggestions for wifi extenders that work well with my current unit.

EX7000, 7500 or 7700 would be a good start.

I forgot to mention that my internet speed is 400 mbps and my house is a little over 1500 sq ft. I believe that my issue is too many devices and as I get to the back of my home the signal strength gets low and even drops in some places

1500 sqft isn't a huge home. if its wood/sheetrock the router alone should be able to cover it if its centrally located. Have you tried that? 

if its other materials (brick, plaster lathe, adobe, concrete, etc) it could cause issues.

My cable modem/router is located on the opposite end of my house from the back of my house. I do not have the option to move my modem/router

I'd recommend any of the tri-band extenders.

the standard extenders loose 50% of the throughput just based on how they function. 

the tri-bands reserver 1 of the 5ghz chips just for router----extender communications so they don't take the massive speed hit. worth it imo
