I have two WiFI routers :
- (A) TPLINK TL3420 connected to internet via 3G USB dongle and is located at "Second floor" of my house.
- (B) ZTE ZXDSL 531 connected to internet via ADSL and is located at "Ground floor" of my house.
Both WiFi routers are sending signals to my "First floor".
Now, I want to have a config which would allow me to access "internet access points" from both the routers all over my house. Basically, make these routers extend each others WiFI access points in their range.
