Running into an issue with my RE220. When I Initially received it I set it up and everything worked fine. Then I noticed a few days later that only the power LED was on. I tried reseting the extender to factory defaults, but now when I try to configure it through the Tether App I get the following error message "Unable to join the network "TP-Link_Extender". Im then brought to a screen where it offers me to connext to the Extender 2.4 and 5Ghz bands, I cant connect to either of those. Ive tried multiple resets and moving the extender around, to no avail.
