I'm not sure why your previous bridge configuration was lost. There is always a possibility that you have a failing modem.
After reset, go back to the modem page, and the VC configuration. First check that the VPI/VCI settings are correct for your ISP. Then set as an unrouted bridge, and reconnect your router. -- AT&T dsl; Westell 327w modem/router; openSuSE 11.0; firefox 3.0.8
