After reboot new desktop cannot browse, DNS works
I recently installed a new Win7 desktop for a client who lives in a senior living community. Connection is a cat5 feed to a d-link router-wi-fi and then cat5 to the wall. At first connectivity was fine, but on reboot, internet access stopped. In CLI, ping command resolves using DNS, but fails with "General Failure". Email and browsing also don't work. I disabled firewall and anti-virus, even took out the anti-virus program. I reconnected the old machine and found the same problem. I restarted the router (d-link wi-fi) and still no luck. What happened here? Is there something about this router I'm missing?
Be shure that your cable is ok. Try connect with your mobile device on this wifi router. If you pass to Internet, it could be cable issue.
Just be sure that your network interface is in dhcp mode.
Right click on binterface icon (bottom right) > Open network and sharing center > (check if you have "Work Network" under active network ) > click on Local Area Connection > click on details.

What do you see?
-Change your DNS settings on the local IPv4 settings on the PC to 8.8.8.8 temporarily (google's DNS) just to triple check that.
-Go to your internet options > Connections tab > Lan Settings....Is it using any proxy settings? Clear them out if so...unless you are using a proxy on the router
-Do you have a laptop that you can try plugging into the router? If it works, that means it's a PC issue and not a router issue.
-Maybe try a simple disable and re-enable of the network card.
Let me know if any of this helps, if not after trying some of those we can further look at our options.

Oddly, enough, the problem turned out to be the desktop's system clock. I didn't think to check it because I had set it correctly during the initial setup. Anyway, for some reason, the clock in the systray was way off and when I reset it. the problem went away. Go figure!

Good suggestion. I guess even though this is a new computer, straight out of box, it could be stale inventory.
post results!
I wonder why as you said - the old computer didn't work either?
i 'd like to know the solution as well
Try this
Turn off the router
Take a cable directly from the desktop or laptop and plug it into the wall outlet
goto a cmd prompt
In the dos box type the following:
ipconfig /release
ipconfig /renew
ipconfig
Note the IP address after the last command
If it starts with 10. or 172. or 168. then the community is behind their own router
Note the Gateway address it usually ends with .1 or .254
Say the Ip address is 192.168.0.123 with a gateway of 192.168.0.1
Now plug the Desktop / Laptop back into the your router either via cable or over the wireless
Go to a cmd prompt and again do the
ipconfig /release
ipconfig /renew
ipconfig
if the gateway is in the same subnet (if the first three octets are the same say
192.168.0.xxx
Then your router is confused. The internet subnet on your router MUST be on a different subnet than the External subnet.
If this is the case you have two choices. Reconfigure the internal IP of your router to something different say 192.168.4.1 or change the router mode to AP. It's a lot easier to change the Internal IP
Then restart the Router and the PC and you should be fine
