RE315 Range Extender delivering a fraction of expected speed
Hello!
I just received and set up a new RE315 range extender which I purchased to extend the range from my WiFi modem in the livingroom to the computers in the bedrooms. The installation went smoothly via the enclosed instructions. I'm subscribed to AT&T's fiber plan and should be seeing speeds up to 500 Mbps, but after connecting to the new networks created by the range extender, the speed is suddenly ~20 Mbps on both 2.4 GHz and 5 GHz networks. The signal strength of the WiFi router shows as "strong" in the Tether app, as well as on the range extender. I've also tried resetting the range extender and reconnecting, but I'm still getting the same speeds.
Is my range extender defective? Am I missing a crucial step in the setup process?
Btw, I used the WPS procedure outlined in the enclosed instructions to set everything up.
Any guidance would be greatly appreciated!
Thanks!
