Verizon Westell 327G wireless connection problem

My IBM Thinkpad laptop does not connect to my Verizon DSL/Wireless 327G Gateway. It sees the network, but cannot connect. The laptop can connect to other unsecured wireless networks in the neighborhood and at other public places, but not to my home Gateway which was supplied by Verizon. The wireless setting on the Gateway are as follows:
Wireless Operation Disabled Enabled
