Hi all. Hope someone can assist me.

I'm setting up a network in guesthouse, the ISP works via fibre, and has provideda gateway router with the IP address 192.168.1.1 

I cannot access this routers web interface, the ISP doesnt allow me to do that.

I have turned off its wireless functionality, and have hardwired 2 Cat cables to 2 seperate routers.

The first is a NetgearXR300, which Ihave set up with IP address192.168.1.4

It works well, and provides internet access for management and staff.

The TP Link is proving to be difficult. I chose it because of the OneMesh capabilities, I have 3 RE305 Range extenders in the guest bedroom area.

The problem arises with the TPlink pointing its LAN interface at 192.168.0.1

I can give it a fixed IP address in the correct range, but then cannot get the tether App to work to link them all together.

My IP scanner tells me that the C7 has IP address 192.168.1.76,  But Tether does not pick up it, or the 3 range extenders at all.

Any advice or suggestions would be appreciated.
