      Re: PC loses connection to router

      If your laptops maintain connection to the internet, then the router will still be sync'd to the exchange, ruling out WAN issues. Regardless of whether windows says the network is 'connected', sometimes it's just a glitch and it really isn't. Easiest way is just to ping the router from cmd and see if you're getting replies, in which case it is actually connected.

      If it is indeed connected as confirmed via command prompt, then the only things that come to mind at the moment is a possible ip address conflict (doubtful, though) or firewall issue (again, doubtful). I say doubtful as it works fine until 11 at night as you say, so I'm placing my money on a wireless issue.

      Re: PC loses connection to router

      Well last night everything worked fine - PC was connected and working all evening, I came up to play poker about 11.30pm, connection was fine.

      Today, PC has been on since 6 and working fine. I came to play poker at just after 12 - it was still working but as soon as I started to use it the connection dropped. Icon says I'm connected at very good. Pinged router, got:

      Rebooted PC. Connection again apparently very good. Managed to open one webpage then nothing.. Pinged again:

      Obviously something's not right :-( But I fire up this laptop, sitting next to the PC, and all is fine, so can't be the router. But if something is wrong with the PC why did it work last night, and why did it work until I came to use it tonight? All very frustrating :-(

      Re: PC loses connection to router

      Also, I have checked my Netgear wireless assistant. This shows me that there is a neighbour who is also on channel 6, and 3 on channel 1. Earlier posts have suggested this could be an issue, so I tried to change my channel from 6 to 11. But the channel bit on my router wireless settings page is greyed out - how can I change it please? And is this likely to be the cause of my issues? Cheers.

      Are you using the netgear software to connect to the wireless network? If so then disable it and use the inbuilt windows software and see if the problem repeats. Could you take and post a screenshot of the greyed out wireless channel? I havent seen that before.

      Re: PC loses connection to router

      OK thanks I'll try that next time, although the PC doesn't have wireless connectivity itself, it uses a USB Netgear wireless dongle, will that make a difference?

      Here's the image:

      Very odd, try changing the region and see if that unlocks the channel option.
      It wont matter that the PC doesnt have wireless built-in you can still use the windows wireless software

      I can't change the region either, it only has Europe in the dropdown list.

      You have to change the Mode to allow you to change the Channel. Use the drop down box to change it from Auto 108 to 'g only'. This will allow you to change the channel. Try Channel 13.

      Sounds like power saving on your network card/stick.

      Look into power saving options on the device itself within device mgr.

      Re: PC loses connection to router

      I had a similar issue to this, every so often my laptop would lose internet access. Windows would report it was connected (wireless) but said no internet access. I'm using Windows 7 and it showed the signal strength icon as full but with a yellow exclamation mark on it.

      The drop in access was getting more frequent over a period of a couple of weeks, mostly I was only without internet access for a couple of minutes but it was seriously frustrating.

      Then one day I got a windows notification about an IP address conflict. I have a number of devices connected to the network; PC, Laptop, Phone, iPod, Printer, PS3, Wii so it didn't come as a great shock.

      To fix it I did the following from a command prompt:

      ipconfig /release
      ipconfig /renew

      I'm not saying this will definitely work for you but it's worth a shot.
