I have an exsisting Point to point CPE710, with basic configuration 192.168.0.254 for base AP, and 192.168.0.253 on client ap.

I am planning to add another CPE710 base AP back to back with my existing AP, will my ip be the same on 192.168.0.254 or differrent one the new CPE710.

Also can I use my old SSID and password? will it interfere or boost the signal strenght?

Actually it is suggestion to change the IP of new CPE like change to 192.168.0.251, in case there is the IP conflict in the network.

And you can keep the SSID and password same as your old one, if you worry about the interfere you can change the CPE's channel to optimize the network environment.

Best Regards!
