With the technician help over chat I was able to pair E3200 WIFI extender with G3100 router. However, when extender was placed where I'm going to use it, it blinking yellow most of the time and sometime only shows solid white. Connection exists even when it' blinking. There are about 25 feet between router and extender with two walls (no stone or concrete, standard frame with drywall). What's wrong and is there a way to fix this annoying behavior?
Are you using the last resort WiFi-backhaul? If so, slow yellow blinking means E3200 is too far from G3100 (poor back-haul signal), fast yellow blinking means E3200 is too close to G3100 (poor WiFi-coverage), according to the User Manual.
