Blocking URL's Using Wireless Router with Wireless Connectivity

Make sure your router's WAN port is set to dynamic IP. If the light on the front doesn't glow/blink for the WAN port, try a different cable. If a different cable doesn't work it's probably toast. :( This problem appears to be directly linked to the relationship between the WAN port and the modem. Given that the devices can connect to the router, but not internet, it has to be the WAN. Sometimes if the modem goes out it will send too much voltage through to the router and fry the WAN. Had that happen to my parents router. If the above doesn't "fix ya" then try a different router.

Worst case, you might have to put a wireless card in your PC and bridge the modem (wired connection) to the wireless card and broadcast for your wireless devices. At least until you get a new router.

Can you clarify the question? Uninstall?

Disable any third party firewall software you have installed.

Hope this helps!

With the Linksys router it is not possible. You will need to connect the cable between the two routers. Linksys router will not pick up the wireless signal from the other wireless router.
May be it will work If you upgrade the DD-WRT Firmware. Not sure but it may. consult with the DD-WRT expert before upgrading the firmware.

Yes that should be possible to configure a range expander with your router.
You can follow the steps from this link on how to do that

make sure your network card is active . for tcp/ip then try resetting all 3 devices router/modem and laptop. (same time) Good Luck.

There is always a wireless option on your router. Check to make sure that your wireless is turned on and that you arent blocking your wireless signal with a WPA personal passcode.

try to upgrade the latest firmware for the router and reset and reconfig it..
