i'M GOING MAD!

UNtil last friday I had been successfully using wifi with the supplier as VIRGIN through their Motorola SB 4200 cable Modem and the wireless router being the Linksys WRT 54G router.

Supported were three lap tops and an EPSON 510W printer and this had been running with no issue for about 3 years.

Back to last friday, we started suffering significant delays and then the network collapsed with no wireless access. I was able to connect a single laptop direct to the cable modem and internet access was restored to just that one device.

I thought that the problem was the router so I tried a backup D-Link device with no success. I have subsequently bought another cable modem AND a netgear router plus addidtional ethernet cables but with no success. The best that happens is that the signal appears good but I cannot get access to the internet. A yellow question mark appears on the 'gradient' icon.

Each laptop and router works elsewhere so I'm stumped. Mind you I am a real novice so I'm not surprised. Please can anyone tell me what I'm doing wrong?
