Who Me Too'd this topic

I have FIOS TV and have one mini box  I use wirelessly since there is no cable access on that wall. In my house I had the G1100 and a WCB6200Q extender since I have 4 floors in my townhouse. and all coaxial connections. The TV picture on the wireless mini would cut out and consistently say it had a poor WiFi connection. I tried moving router ect, but it remained and issue.  I was told by VZ that if I upgraded to the G3100 it would improve the TV picture/signal. So now if I use the G3100, it seems to help with the tv issue(so far), but I don’t have the WiFi coverage in the house with just the G3100. Therefore Instead of spending even more $ on a new extender, I was wondering if I could use my G1100 (or old extender) in conjunction with my G3100 to extend my coverage?
