Good day.

Sorry for the delay.

It is not available to set up RE with two routers since RE did not support multiple IP ranges;

For the SSID issue, did you set up RE via the WPS button, or copy the SSID of the home router during the setup?

If yes, please refer to the following instruction:

1. Connect a computer via Ethernet cable to the RE450;

(if there is no wired computer, please unplug the router for a while to check if there is still the home router SSID; if it was, it much be the RE450;)

1. Log into the RE450 via http://tplinkrepeater.net
2. Change the SSID under settings>wireless>extended network;

Thank you very much.
