In all instances, the phone laptop tablet all say that I am connected to my network, with a strong signal. The modem's lights are all one and everything looks normal but I can't access the net.
It seems to happen overnight so when I get up there is no link although it has been happening at other times of the day as well.
If I reboot modem, the connection comes back.
One day last week the phone and tab both lost internet link although icons suggested all was Ok yet the laptop was OK and I carried on working. Eventually the phone and tab re-connected with no intervention from me.
So, that is it. The line coming into the flat is Ok as far as I can tell. I live in Italy and getting help from Telecom Italia is hard but the fact that when the connections are all OK I get an excellent, fast internet service.
My guess, as a complete tech clutz, is that there is something wrong with the modem.
Would that be on the right track?
