Hi,

I am trying to add a WPA4220 to an existing network, consisting of - 

TD-W9960 router, 2X BT mini-connectors (sorry!), 3X TL-PA4010P, and one WPA4220, all working perfectly and stable.

I have been trying to add another WPA4220 to extend the wifi access.

But, having followed the instructions to add strange things happen.

1. the new WPA4220 seems to clone the existing settings, name and password. Is this correct?

2. I can access the new extender wifi, but no internet access.

3. Having both WPA4220's on the rest of the network ceases to work. No connection through any of the wired powerline adaptors. TV STB, Hive etc. stop working.

4. Switching either of these off restores connectivity.

I have repeated this several times and done resets on both.

Any suggestions, please?

Thanks,

Peter
