Hello adrianlondon, thanks for your interest.
After a restart of the UPC Connect Box, the cable to the router is still connected at one of the LAN ports, and I suppose, occasionally, that that is the port selected by the box, so I don’t notice anything; more often, it isn’t, and then I notice that the connection to the internet has been lost. So what I do is re-plug the router in the other LAN ports one after another until I see activity at the port (flashing green LED - though note that this takes at least 30sec to show after plugging the cable). ( I can confirm that the connection from my LAN to the internet correlates 100% with the flashing green LED at the port. ) Admittedly, once I have seen activity on a port, I don’t go on to check whether there is any activity on any ports I haven’t yet checked (if any) .
As all the ports have worked at one time or another, I suspect a software (i.e. design) problem rather than hardware. I called UPC about this problem a long time ago (~2 years), and at that time, they said it was a known issue and that they were working on it; I didn’t hear from them about it again. More recently, I called to enquire if they had solved the problem, but I was told they didn’t know about the problem, and that it wasn’t possible, and that they didn’t offer support for problems arising in bridge mode.
Best regards, JGP.
