I changed the IP address on the router and now can’t access the web interface

ipip addressrouter

I changed the IP address on my bt home hub 5 router from 192.168.1.254 to 192.168.0.254 because I was trying to connect to an IP camera – big mistake. Now I can connect to the router but there is no internet available and I can't get the web interface to put it back the way it was. I've tried resetting the router but this doesn't seem to do anything. Can anyone help? Ta

I've done this successfully. You need to move your machines from 192.168.1.* into the 192.168.0.* subnet. If they are all on DHCP you can reboot, but it is a lot quicker and easier on Windows to use the connection repair function, or from CMD:

ipconfig [/all]                # to identify the interface name
ipconfig {interface} /release  # to clear the current IP address
ipconfig {interface} /renew    # to assign a new IP address from DHCP
ipconfig [/all]                # to check the new IP

On Ubuntu, you can simply disconnect and reconnect the interface.

If the interface has been set manually, you will need to change the assigned IP and gateway within the interface's TCP/IP properties.

Once a machine is in the new subnet you can then access the router again through 192.168.0.254.

It should take only a couple of minutes.
