1394670 2015-02-20 14:01:00 It's likely that your PC got it's IP address from DHCP, which went something like:
- Use this IP address
- Use this subnet mask
- Use this as the Gateway address
- And use the Router as the DNS Server

You can check this by bringing up a command prompt and typing:
ipconfig /all

Basically, when that happens, your routers DNS server has died and is in the process of restarting. Your router basically forwards the requests off to your ISPs DNS servers, and it's supposed to cache some requests to keep you from having to go out onto the internet every time you need to ask "Where is facebook.com?"
What I'd suggest you do is manually specify your ISP's Primary DNS server in your networking settings, and use Google Public DNS as a secondary (8.8.8.8 or 8.8.4.4)

You can do that and still use a DHCP IP address by telling windows you want to use a manual DNS server only. Leave the IP address allocation settings as DHCP.

I'd be willing to bet your issue goes away after that, because your PC is going to the internet for its DNS requests as opposed to your router, so it doesn't matter if your routers DNS forwarder crashes, coz you'll continue being able to use your ISPs.

Give it a whirl and see how you go :) 		Chilling_Silence (9)
1394671 2015-02-21 03:17:00 Interesting you bring this up. I went to Spark unlimited this week and have been having problems with web site not found since then... When I click on the bookmark a second time it's OK. Same on two PCs.. paulw (1826)
