I have just purchased a new lap-top with windows 7 and I can't connect to my network (cable gateway) It shows a wireless connection excellent strength.but doesn't connect.I can connect to a unsecured neighbor.
Can you connect to your own wireless if you disable wireless security in the Netgear unit ?
If so, you need to make sure that you select a protocol (preferably WPA) which both devices support. If you must use WEP, try noting the HEX translation of the passphrase used and apply that to the laptop wireless user interface.
I had this problem as well. The only fix was to change to WPA2-PSK (personal) on the Netgear router and do the same on the wireless card/adapter. I tried working with my ISP technical support and Dell technical support for over 17 hours and NOTHING they suggested worked.
