@AkshayGunplay edit - ethernet cable to satellite router archer c6's wan* port

@AkshayGunplay i forgot to add - i have connected both the routers using an ethernet cable, xc220 being main router ethernet cable from main router's lan port to satellite router archer c6's lan port...

I'm facing the same issue. Using the exact same models however my Archer C6 just wont show up on the easy mesh add device screen. Did you find a solution to this?
