I posted earlier last week with this same problem, I am getting "Network Availability C130" Message again. There was a problem within my area but this has since been fixed, apparently!!!
Unfortunately its not fixed for me. I had a text saying the problem was fixed, but but still having problems text back Help, i did so, got to wait till 4pm to see if they can sort the fault. I am missing out on watching the athletics in Olympics on Red button BBCi Player, i can't do this and its been a week now 🤔🤔😞
Thanks for the tip. Just looked on virgin site for problems in my area, and its showing there is a problem again and a technician is trying to sort this. Been a problem for a week now nearly. In the meantime i will try what you suggest, but i am able to watch some on my Amazon fire stick, well the BBCi Player anyway
