Hold in factory reset button at back for about 1min. Once restarted, this is the important bit and why I couldn’t get on. You need to set your NIC IP to static. Use an Ethernet cable to plug directly in back (maybe able to get on via wifi if it’s been set to on). IP of Linksys should be 192.168.1.245 so set your static IP to something on same subnet, like 192.168.1.10 and subnet 255.255.255.0 and leave reset blank for now.

That’s it. Then in your browser put 192.168.1.245 and you’ll get asked for login details. This is also the annoying bit as appears to be no user name, so just leave blank but the password is admin
