Hi,

I have a WiFi router in a lounge that cannot be moved and two outdoor cameras at the rear of the house.

I have the TP-Link TL-WPA4220 TKIT 2-Port Powerline Adapter WiFi Starter Kit, one seems to be good for one camera which is at the rear of the house and the other which is in a detached garage in the garden. 
 

Can I use a TP link router (AC2100)as some kind of access point in an extender to boost the signal? 
 

Or has anybody got any suggestions on how to boost the signal at all for the extenders? 
 

Thanks. AC
