I've got the Comcast XB3 modem/router that does not provide a stable 5GHz signal to my back rooms. These rooms are maybe 50 feet from the router and pass through 3 or 5 walls. My router does not do AX and since I only have 350Mbps service, won't be getting an AX router (I do have 3 devices which support AX). I've been looking at the EX8000, EX7000 and the newer EAX20. I know the EX8000 and 7700 should mesh with my current router. Does the EAX20 do this, being it's only a dual band? I currently have my 2.5 and 5GHz channels separate on the XB3 and don't trust it's steering capability. Can any of the extenders mesh each channel individually?
both are triband extenders. The benefit to tribands is that they have a dedicated 5ghz chip just for router---extender communication.
Most standard extenders (dual and single band) take a 50% speed hit because they have to use the same chip for router---extender communication and then extender-----device communication. And they can't do both at once. Because of the dedicated chip, the tribands don't take that speed hit.
The XB3 isn't a AX router so upgrading to an AX extender isn't going to be much benefit because the connection back to the router is still an AC connection.
