Hi all,
I'm getting a problem where the internet starts running very slow and then eventually drops all together. I'm trying to diagnose what's going wrong, but I'm at a bit of a loss. When it is working, I'm getting about 10% packet loss on a ping to google, in usual surfing, it's a painfully slow experience!
The Virgin Superhub is running in Modem Mode. Attempting to reach it at 192.168.100.1 99% of the time results in:
The server at 192.168.100.1 is taking too long to respond.
The other 1% of the time when I'm really lucky, after a long wait, I get a page load. I used these page loads to try to get to the log - which seemed to be suspiciously empty other than these items :
Network Log First Time Last Time Priority Error Number Description

Eventually, the internet comes back after a long wait, buy doesn't stick around for longr

At the moment on doing a speed test, I'm getting
Ping: 10ms
Download Speed: 23mbps
Upload Speed: 10.82mbps
But when it starts getting bad, I can't even get the speed test past the ping!
This should be on the 50mbps plan I believe
Any ideas? I'd really appreciate any thoughts or suggestions :-)
Thanks!
