Just a PSA really.
We have had cable from Virgin since 2010. Normally fine but just recently the broadband service has started to drop off in availabiloity. Most weekends it'd go away for a few hours at a time. I complained a bit and they agreed that my old router might be a bit dodgy and said they'd send a replacement out.
The superhub arrived today and after a bit of messing about, it was online.
Our download speed doubled immediately from 10Mbps to 20Mbps. Upload went from 512k to 1M. Wireless signal has jumped massively and I can get it now out in the back garedn on my iphone which I couldn't before.
If you're having problems with your old Virgin router, browbeat them into sending a new one out.
