Notebook adapter connection issue

SOURCE: Replaced Linksys Wireless-B 2.4GHz 807.11b

Try resetting your IP address:
The laptop may be trying to use the IP address from the old router.

1) Click Start (assuming Windows 2000, XP, or Vista)
2) Click Run
3) Type in CMD
This will take you to a black command box
4) Type in: ipconfig/release
The chart should show your IP address as 0.0.0.0
Once this has happened, proceed to step 5
5) Type in: ipconfig/renew
You should now see a new IP address listed.

Also note that you need to set up your network key (assuming that you are using one) on both the router and laptop.
Make sure that your router is set up to perform as DHCP server.

Most of the newer routers use a newer type of encryption (WPA or WPA2) which is not supported by older 802.11b hardware.

Either set the Linksys router to use WEP encryption, or get a newer 802.11g card for the old laptop which can use WPA or WPA2 encryption.

Older versions of Windows XP also need to be upgraded to Service Pack 3 or apply this patch:
