I recently added an E3200 Extender to my 3100 Router.
Using the WiFi setup, I hold the front Buttons on the 3100/3200 and they both flash BLUE.
They both go solid BLUE after a while, then the router goes WHITE and the Extender goes Solid YELLOW.
I have read that perhaps I should wait for the Extender to catch up??
I have waited 12 hours.
Help?
