Wireless adapter not connecting to internet

[jackz15]

For some odd reason I cannot connect to the internet with my NETGEAR wireless network adapter on my laptop. The adapter works fine on my desktop and had worked fine before on the laptop as well until a few days ago. The laptop shows that it detects my router and has excellent signal but once connected I get the "limited internet speed balloon". Also, if i connect my laptop directly to the router it can go online. From all of this, it seems like neither my adapter nor my router is at fault. What could the problem be?

Thankyou very much

Is the wireless key definatley correct, 9 times out of 10 if your wireless connects but with limited connectivity it's because there is something wrong with the key. If it's WPA encryption make sure the case is also correct. Is access control enabled? If so you may need to check that the MAC address is listed on the router.

The internet stopped working abruptly. I did not edit any of the previous settings and it stopped working. However, I do have a WPA encryption, so I'll try what you said for that. Since I didn't change any of the settings, would I need to check the MAC address?

oh, I just had the opportunity to check. Access control isn't enabled. And the key is definitely correct. Is there any other possibilities?

Other suggestions would be to check you are getting an IP address (I assume this comes from your router), if it's a laptop has it been connected somewhere else? If so is the wireless set to use a static IP address rather than getting one from DHCP on the router?

You may want to try and reinstall the wireless drivers.

Is there a firewall? If so try to disable it temporarily as a test to make sure it isn't blocking anything.

I believe that the laptop is supposed to be set to use IP from the DHCP, but with the limited wireless connection I found that the IP was unknown. Is this because the laptop failed to get the IP from the router?
I will try to reinstall the drivers once I get home.
Thanks!

it didn't change after i reinstalled the driver. After disabling APIPA, my IP address and subnet are all 0.0.0.0
DHCP server is 255.255.255.255. What is going on?

Maybe something got corrupted. Try to uninstall/reinstall the wireless card from device manager. If that doesn't work create a new network connection.
