Problems with mobile devices on new fibre router

[#1]

Hi. Got our new router up and running at the weekend, but I'm having problems keeping iOS devices on the network.
For some reason it keeps defaulting back to 192.168.1.1 as the router address.
I have tried the following
Forget the network
Reset network settings
Setting static IP
The only way I can see round it is to change the router IP to 1.1
Will this be a problem?

I've never noticed that with iOS but it shouldn't hurt to change the LAN IP of your router. Or wrap the MAC of your iOS device to a specific IP on your DHCP client listing and use static IPs, specifying your default gateway as the original IP of the router, would be another way of dealing with it.

Changing the IP of the router back to 1.1 worked.
All my iOS devices and the Kindle that was also failing to connect are now happily on and staying on.

Glad all is working now 🙂
