1.Log into router. Using either 192.168.0.1 to 192.168.1.1 in a browser window that is ( internet Explorer or Firefox)
2. Verify wireless router name( on the computer) >>> ( on/off) ( router status window)
3.Note router name you are connecting to.
4.. Check the laptop do ipconfig /all to see current IP addresses.
5. Set the laptop up in the router by WEP KEY or MAC address. This set up in the "security tab" in the router. using 192.168.0.1 or 192.168.1.1 to access through a browser.
6.Note router name you are connecting to.
7. Move the laptop about 20ft away and try to log on to the internet.
This is for all routers to set up wirelessly.
8. check for firmware update at the manufacturers site for your model router
9. cell phones, cordless phones, digital TV's, can affect the data signal from a router. Also distance from the router can be a factor. If your router is in a basement place the router to a upper floor and center it in the room.

The wireless card may be swithed offGo to control panel and select "wireless connection" windows will detect the wireless card and tell you if it's swithed off.

your laptop may be using wireless b specs while your dir300 is setup to give out wireless g signal only. try to set it to mixed mode.

go to your adapter settings for the notebook that does not work and clear off your network connection try to re-discover your router, and enter the same code you used to log in with the notebook that works. Sounds like you have an IP from the router, but no access.

I've had this happen before when using a USB wireless device. Is the wireless on your system built in? Or do you connect it to a USB port? The external devices sometimes try to use their own software to configure wireless so you can shut it off and just use the Windows wireless tool. I assume you setup the wireless with a security key and entered that key into your system to try and connect? Let me know if any of that helps and rate the solution if it does!

A few more thoughts:
1. Have you installed or changed any firewall or security settings?
2. Try resetting the router, turning off the modem for a minute. Then turn them back on and give it another try.
3. Are you sure that your laptop is connected to your router and not your neighbor's? (Look at "Network Connections" in control panel.)
4. If you have another ethernet cable, connect to the router with a cable and then try to reach the internet.
5. If none of this helps, then look under the couch cushions for some cash to buy a new router.
6. Good luck!

mairelina, if all was well 2 days ago then resetting the router should fix your problem. usually a small button on the back of the router.

chelliepooh, you need to check that the router's wireless function is on. connect using the ethernet and go to the config page (usually 192.168.1.1) make sure wireless is on and security is set to wpa-psk.
