Comcast's attempt to expand WiFi hotspots around the country has been met with a class action lawsuit in San Francisco by customers who claim the cable giant is trying to use their wireless routers to let others access the Internet. According to the Courthouse News Service , the lawsuit was filed in U.S. District Court by lead plaintiff Toyer Grear and it charges that Comcast gave unsuspecting customers across the country routers that would broadcast secondary signals allowing others to connect with the Internet without the customer's approval.
