I have a new linksys EA6900AC router and 3 re2000 range extenders. First all appear to be set up correctly on the network. Signal on my iphone is strong, but only one of the three show up in the device listing. The range appears limited for each as well. All are set to the 5Gb side of my network. Should I worry that they are not showing up in the linksys listing? Thanks.
Also can I setup an extender by attaching to another extender to improve range in areas where distance to router is too far for a good direct connection to the router?
