Change your router DNS entries to something more reliable. They're probably pointing to your ISP DNS servers.

Google DNS: 8.8.8.8 and 8.8.4.4

Open DNS: 208.67.222.222 and 208.67.220.220

Alternatively, you could just change the DNS entries on your computer.

how to change the DNS entries on the computer? you mean going to the TCP/IP settings of the active network connection? – Mat – 2011-05-09T11:22:17.383

1@Mat Yes, that's correct. Usually with Windows you also have to set up a static IP in order to change the DNS entries (something I hate and wish MS would fix). Use 192.168.1.x as your IP, where x is outside your DHCP range, 255.255.255.0 as the subnet mask, and 192.168.1.1 as the default gateway. – MBraedley – 2011-05-09T11:54:14.590

Your DNS servers are wrong.

Go first into the router's control panel (probably at 192.168.1.1) and ensure that the DNS servers are as communicated by your ISP (or choose among Google Public DNS or OpenDNS or DNS Advantage).

Go into the Properties of the Wireless LAN adapter, then into the Properties of TCP/iPv4 (or/and 6), and select "Obtain an IP address automatically", do the same for the DNS server, then OK.

Downvote a correct answer without explanation ? – harrymc – 2011-05-09T16:57:16.433

I didn't downvote, but this doesn't take into consideration that the problem isn't the DNS server settings, but possibly the DNS servers themselves. – MaQleod – 2011-05-09T21:22:33.980

@MaQleod: 3 alternative DNS servers are listed. – harrymc – 2011-05-10T04:51:37.053

Switching servers patches a problem, not fixes it, and doesn't identify it either. Also, ISP DNS servers are best to use for a number of reasons, most important of all being response time. – MaQleod – 2011-05-10T07:04:29.693

@MaQleod: Not always - DNS Advantage is faster than my ISP. – harrymc – 2011-05-10T08:26:10.293

The only advantage to ISP DNS servers is that they are geographically close. This does not mean they are fast, and they aren't always accurate. – MBraedley – 2011-05-10T10:52:13.393
