Returned home after a week away. I switched on wifi hub expecting mobile to connect but it can't, it say's it cannot connect because it can't find IP address? My wife's mobile can however.
The only thing I can think of is I have agreed to an upgrade, it was supposed to be delivered last Friday but subsequently changed to Saturday which was too late as we were going away. I managed to change the delivery to Monday week which is still two days away. Is it possible my contract has changed before I've actually received the new phone and would that cause the IP address problem? If not then I haven't a clue as to what the problem is?
Trying to get help from Virgin has proved fruitless so far.
Many thanks for your quick reply and info, particularly confirming the change of contract would not of caused the issue. This way I could focus on the phone or, as it turned out, the modem. It became apparent early evening, that my wife's phone wifi connection was intermittent at best so I tried, once again, switching the modem off and on and this time, after a few minutes wait, both phones finally got a solid connection and they have remained stable since.
Presumably switching off the modem for a week was the problem after all, not sure why that would be but thankfully all is well now.
