I have an issue with wifi on laptop Dell N5110 Windows 10x64 clean install (Broadcom 802.11n Network Adapter). WIfi goes "no internet" every 5 minutes. Other devices have no problems with this router. What I treid to do:

  • reset via NETSH
  • check power management
  • choose channel number manually
  • remove WiFi driver, ethernet driver via control panel
  • remove WiFi driver via Device manager
  • use pnputil

none of this worked, but intresting that removal of drivers via Control panel had no effect - wifi worked like nothing happened. I tried to remove driver via Device manager, scan for changes and driver is on it's old place again instantly like nothing happened. Please help to remove driver completely to install again.

  • When you do the clean install are you removing your partitions before you install Windows?

  • If you are going to push back, and require me to explain every question I have, I just attempt to help somebody else. Why can’t you just select the correct driver you want manually within Device Manager?

  • You don’t have to delete the driver to select a different driver, I assumed you have a device driver you want to use, if your attempting to delete the existing driver.

I have chosen 2012 driver instead of 2013 in Computer Management - Device Manager - Network adapters - Broadcom Network Adapter - Properties - Driver - Update driver - Browser my computer - Let me pick from a list - Uncheck Show compatible software - Choose broadcom driver with the same name but lower version - Reboot. Everything seems to work fine so far. Hope it may help someone eventually.
