A friend is having the same problem as you.
All services were working perfectly fine though until there was a Virgin service issue in his area. Since then he's had Wireless access only - not the fast broadband service he is paying for.
All internet access is at the back of his house, to which many years ago he arranged to have cable built into his roof from his Virgin router to that room. From this point in his rear office, he has a small 5 port switch which has given him perfect broadband service for years - until the Virgin downtime a week ago.
I helped him get through to Virgin support by phone the other day and they insisted it was a service issue with Virgin, despite him having internet to his home via Wi-fi only, which doesn't make any sense to either of us - if the cable running to his home (and his neighbour) is working to supply the service how could it differentiate between allowing just wi fi and block an ethernet service!)
The person stayed on the line whilst we turned the router off for a few minutes - and even (as suggested by one of the messages here) do a reset hole procedure and I really hoped that this may resolve the problem, but to our dismay nothing changed.
Can you help me understand how a service can be partially available within a home?
I've never come across this before, usually internet or phone is either working or it's not.
Thanking you in advance.
