Until last friday I had been successfully using wifi using a Linksys WRT 54G router. My ISP is Virgin and I am using a Motorola SB 4200 cable Modem

I have three laptops and an EPSON 510W printer connected wirelessly 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 additional 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?

  • Start with all devices unpowered for a minute.

  • Connect the router to the cable modem, using the correct 'internet port' on the router.

  • Power up the modem, wait a minute, power up the router.

  • Connect a single PC to one of the other ports on the router.

  • Internal check: In a browser, navigate to the routers config page, normally http://192.168.0.1 or http://192.168.1.1 and check that is working.

  • External check: Next open a 'Command Prompt' window, type 'ping 74.125.132.102' and see if you get a response.

  • DNS check: In the same 'Command Prompt' window, type 'ping google.com' and see if you get a response.

  • If all is working, repeat with but connected to the router by wiress.
