I have an hp pavillion dv5000 with the broadcom 802.11 b/g wireless adapter onboard. I am using a zxyel 330 router connecting to comcast via a US Robotics cable modem.
If the system sits for awhile, or hibernates, I lose all internet connection unless I reboot. I have tried disabling/re-enabling the onboard adapter, tried the repair function, stopped and started wzc, turned off wzc and tried the broadcom wireless config utility, have disabled the power saving and minimal power consumption options for the adapter - the problem still occurs. This morning I discovered that if I disconnect from my router and grab a neighbors open router signal, it immediately works without having to reboot. As well, if I then disconnect from the neighbors signal and reconnect to my wireless connection on the zyxel router, my connection is then alive again. What could possibly be causing this and is there a better fix than hopping around the neighborhood for a "jump start."
