I use the EAX-20 with the RAX-200 and it does a fine job in my environment. The EX7700 also worked well, though the EAX20 seems to provide better coverage in terms of distance and speed in my environment. YMMV. Disclaimer: I received all of these devices as free beta testing units. That being said, my opinion is not affected by this.Is it best to stick with a tri band extender, while using a tri band ax router like this one, or does it matter?
The dual band extenders seems to get better reviews than the couple of ax tri bands that netgear has..
