Most of the time it's a problem from both sides, device and router, where you should concentrate on the functions of the router,
all brands use different names for the same function(s)
When a different internal IP adress is given everytime the Logitech boots, is not good, the router's firewall or DHCP server might block things, look for a function to "lock" the radio/device, so it will keep the same internal IP address, also WiFi settings good be a "bug" in way of different timing settings, causing time-outs, trying different WiFi channels might also work,
if these things i mentioned aren't the cause, you might considder a new router, because it might be out of your reach due to old hardware, for today's standards.
At the moment, i have a so called gaming router, and it just works fine with almost everything in default setting.
( a router should just work good without much changing it's settings)
btw. after some Googling, i guess your router is a rebranded Netgear one, also Virgin Media took over from Telewest .....
this might give some clues .... does Virgin Media has forums ?
