Hi there ! I am facing a very serious issue after upgrading to windows 10 my laptop does not detect wireless networks those are broadcasting over channel 8 this leads to very irritating at time as I can not change the channels of public Wi-FI networks and make me unable to work . Any one facing/faced the same issue and know how to fix this please let me know it will be highly appreciated . My laptop is Dell Inspiron 3543.
I like to suggest you update the System Setup(BIOS) and the wireless driver(look under Network) in installation order on your laptop. Please enter the service tag number on the link below, then download the BIOS require onto the system and install it.
