I got my VirginMedia TV and Broadband (200MB) connection recently. It works fine most of the time, but my TV Box keeps loosing Wifi connection. I have noticed this happen few times on my mobile phone as well. If I reboot the devise or the WiFi Hub, connection comes back again. It is so annoying.
VirginMedia says there are no limitations to number of devices we can use. I have about 8 devices, including mobile phones, laptops and tablets connected. I can understand lower bandwidth if all these devises are connected together, but it can't turn off some devices.
