Live Search on Verizon DSL WIFI WEP

[gambatte]

Hi:

I have an XV6700 running WM6 (stock WM5 had same issues with Live Search). When I run Live Search from home Verizon DSL, WIFI, 128-bit WEP security network, I get error message "Sorry, can't complete search request. Please check your network connection." I know an internet connection exists because IE, Windows Live, and Yahoo 2.0 Go! work fine. Live Search runs fine on unsecured WIFI networks, e.g. airport and coffee shops, and on EV-DO network.

Is there some setting on WIFI adapter card or registry hack that I am missing to allow secured connection? Anyone else running Live Search successfully on Verizon network? I like the Gas Price search function on Live Search but don't have an unlimited data plan ($60/mo is outrageous!).

TIA.
