I was recently brought a compaq presario f500 with an amd turion64 processor and a broadcom modem. The wireless assistant light stays red no matter if it is turned on or off. the computer shows no wireless networks and upon trying to use dial up internet that won't work either. I went to device manager saw an exclimation mark by the modem and tried trouble shooting the problem from there. Upon downloading the latest drivers and updating wireless assistant still no internet service is working and the light is still red and I still have an exclimation mark on the modemin device mgr. I am beginning to lean toward a system bios or motherboard problem. Any help would be greatly appreciated ib fixing this problem.
