If I try to access the Hub via 192.168.0.1 the request times out. I also tried 192.168.100.1 (though I am reasonably certain the wi-fi has been disabled - no Virgin network appears in my wi-fi menu) and a screen opened requesting I enter the settings password; however I could not progress as it did not recognise the settings password printed on the base of my Hub.
I wanted to check the settings as my home wi-fi network (an Airport Extreme connecting to 3 Airport Express units) has been unreliable of late.
The key to this one is to get the password right! Your Hub 3 is likely to be in modem mode hence responding to 192.168.100.1. So someone has changed it to something unknown. The only solution if you haven't tried it is a factory reset so as to get to the default.
This isn't as easy as the documentation (such as it is) implies. The paper clip must be held in until you see the modem lights flutter. Takes up to 30 seconds.
If that doesn't accept the default login password (which is a set of numbers iirc), then the VM bods when they get to this thread are likely to send you a replacement hub.
Yes, thanks Sephiroth, I took your advice and did a hard reset. The signal has been constantly good so far - I had a problem with the connection regularly failing for a few seconds. You were right to suggest making sure to depress the reset button for longer than the thirty seconds suggested in the manual - I had to make two attempts having not held it for long enough first time around. Anyway, thanks for the help.
