Have a Buffalo wireless router running DD-WRT. It was working fine but suddenly today I can't get any internet through it. There is no internet connection if I connect via wireless or even the LAN port. This is what I see if I try to go to any website:
This webpage is not available
The server at www.baidu.com can't be found, because the DNS lookup failed. DNS is the network service that translates a website's name to its Internet address. This error is most often caused by having no connection to the Internet or a misconfigured network. It can also be caused by an unresponsive DNS server or a firewall preventing Google Chrome from accessing the network.
Here are some suggestions:

I've reset the modem, I've tried two different laptops and both have same problem in that they can't connect through the router. Any ideas?
P.S: the wireless adapter in each laptop is set to automatic DNS.
EDIT:
I have Internet if I connect directly to the FTTH modem. Also, another wireless router I have works.
Have you spoken with your ISP to ensure they're not having an outage in your area? How navigating by IP address, does that work? – Ƭᴇcʜιᴇ007 – 2011-11-01T19:49:57.853
i have internet if i connect directly to the ftth modem so its a router issue. Also another wireless router i have (free one) works. – Daniel Gratz – 2011-11-01T19:54:02.670
Then it sounds like your router is probably broken. Have you tried resetting it to factory defaults (if it allows this)? – Ƭᴇcʜιᴇ007 – 2011-11-01T19:59:45.657
Broken? It's only 1 day old... i did flash ddwrt onto it from the default firmware but it did work for a day... resetting to defaults didnt help. – Daniel Gratz – 2011-11-01T20:10:20.307
Well flash the factory firmware back on and try that. If you can't, then you probably now own a 'brick' (as you may have invalidated the warranty by replacing the firmware). How about a re-flash of DD-WRT? – Ƭᴇcʜιᴇ007 – 2011-11-01T20:16:07.307
Try to use openDNS in your DNS field. Do this command ipconfig /flushdns. Hope this helps – None – 2011-11-01T20:40:16.933
