browncat22,  Try switching your wireless router to channel 11.   Rick
My Dell vostro 3560 with windows 7 professional keeps disconnecting using the broadcom 802.11n wireless adapter. It does this three or four times a day. My laptop is 3 metres from router, and all other wireless devices stay connected. Sometimes rebooting laptop resolves problem....sometimes reseting the adapter solves problem but not every time. It seems eventually the laptop picks up the wifi in its own time. Please can someone advise me on this
