Their DHCP lease time is only an hour apparently used to be 7 days but they reduced it for "various network side factors" they told me. (I had a separate issue with something and support mentioned that!)If they are using DHCP might need the lease to be released or wait for it to expire to switch to a new router. Would expect if you were on to support they would have released it manually or told you the expiry time. Spoofing the mac address would get round that aswell.
