Hi team

Need assistance or tips

Linksys wireless-G PCI adapter with speedboster on desktop

Netgear dualband wireless-N gigabit router

The computer connects to my neighbors network so i know it works
My other computers and phone are able to connect to the router w/o problem

But i can't connect this wireless adapter to the NetGear... Firewall is off in windOws XP

What do you think?

Oh and the router is visible but when i write my WPA key, it tries but doesn't connect

Brief summary and likely cause: as observed, the PCI wireless-G card can see other APs but fails to authenticate to the Netgear. was right to question the passphrase. The behavior described points to an encryption/compatibility mismatch (WPA2/AES on the router vs only WPA/TKIP support in the adapter or its driver), or a client/utility conflict on Windows XP.

Practical checklist to diagnose and fix:

  • Verify adapter model and driver: open Device Manager -> Network adapters -> adapter Properties -> Driver tab. Update the driver from the Linksys support page (or the adapter OEM).
  • Clear the stored profile for the router: Control Panel -> Network Connections -> Wireless Network Connection -> Properties -> Wireless Networks -> remove the network, then re-add it manually with the correct SSID and the explicit security type (WPA-PSK or WPA2-PSK) and encryption (TKIP or AES).
  • Try the alternative wireless utility: if the Linksys vendor utility is installed, disable it and use Windows Zero Configuration, or vice versa. Vendor utilities can block Windows from managing the connection.
  • Test with router security set briefly to a compatibility mode: enable WPA/WPA2 mixed or WPA-PSK (TKIP) for a short test (do not leave TKIP long-term). Also ensure the SSID is on the 2.4 GHz radio (older G cards cannot use 5 GHz). Disable MAC filtering/WPS for testing.

How to interpret results and next steps: if connecting works only when the router is moved out of WPA2/AES, the adapter lacks WPA2 support — update drivers or replace the card with an 802.11n/ac adapter that supports WPA2/AES. If problems persist after driver and router changes, review the router’s auth logs and Windows Event Viewer for 802.11 authentication failures and consider resetting router settings and reconfiguring security. Thanks to and for the troubleshooting pointers already posted.

Router was set to accept WPA2... Adapter is only WPA...

So i changed the router to accept both WPA-PSK & WPA2WPA2

Thanks to caperjack i was condensing on that asPect
