It's hit and miss at the moment. Sometimes I get a "no signal" message. Then I have to reboot the V6 box which has been upgraded since last Thursday to a 360. I sometimes have to do the reboot of the box a few time until I get a "Welcome" message in a range of languages. After that, if I'm luck(!) I get a "Please Wait" message briefly and then if I press the tv button the TV I get another "Please" wait and then the Virgin Media log. Then I know I'm in.
I went through all the advice via WhatsApp, did all the advised steps. Still no stability so I went for a phone call with an agent. He took me through steps I'd already done and eventually decided it was a faulty box! So a technician from VM is booked in for Tuesday.
This is the first time I've needed technical help since WM was installed many years ago. I had the Tivo box initially, then the V6 and managed to plug and go with ease.
The agent was kind enough to upgrade my new package again with no charge. So if the techie gets it sorted I'll be happy with the agent's response.
