WNDA3100v2 wif problem

ok first time posting...so my wifi adapter after a while will just show a yellow icon on the wireless icon and when i click the icon it says ,no internet access-limited connectivity and only shows the wireless connection im on and no other networks.and then when i disconnect from the network it shows a red x icon and says not connected no connections available even though it is connected on the usb.the only solution is to replug the usb adapter again then it works.also on event manager it says wlan extensibility module has stopped and gives the path c:windows/system32/bcmihvsrv.dll and its a wlan autoconfig has stopped event id 10002.thanks in advance!

Sometimes the Control Panel, Power Options settings for USB turns the ports off to save power, could be causing the issue.
