IPv4 gateway original 192.168.0.1 changed to 192.168.1.254 (which is address of my homehub)
IPv4 broadcast original192.68.0.255 changed to 192.168.1.200
Use custom dns servers original 192.168.0.1 changed to 4.2.2.2
just changed ipv4 lan adaptor to 192.168.1.123 and im back in the back end of the avalon now (one step forwards again)
studio:-
Yes to get into my homehub i type 192.168.1.254 does this sound right?>
Now that you can log in on subnet "1"
Change your network protocol to DHCP: path Network/Interfaces/Lan..... then change the protocol to DHCP.
You are going to loose connection....don't worry. Change your computer's address back to the "0" subnet. (ex: 192.168.0.121)
Now log into your router. Look for all your network devices ip addresses. Get the new address for the Avalon.
Place that address in your browser and log into the Avalon.
DHCP is your problem.
