I Bought a new dell g3 about 3 weeks ago it comes with wireless card Intel AC 9462 and since i got it am facing random disconnections it could take 10 hours or more to happen sometimes less and i cannot find reason behind it.
Thing i tried to fix the issue with no success:
1- install drivers using windows updates
2-install drivers from dell site
3- install latest drivers from intel site
installing and un-installing of drivers to latest versions or older version did not fix the issue.
4- uncheck the box that allow wifi to turn off to save power from device manager under network adapter even though i always have power cable connected
5- run network troubleshooter it finds no issue
6- run troubleshooter for adapter also no issues
7- installed different windows 10 versions form 1709 to 1809 still same issue
8- reset wifi settings on pc
9- using static ips and google dns servers
10- changing roaming aggressivness to lowest
11- resetting winsock logs
12- disabled bluetooth drivers since i read somewhere it might cause conflict with wifi since they use same card
13- un-installed intel proset
14- i formated my laptop 3 times still no luck
Now some might say that issue is with router that i have so i tried using wireless adapter that i got and connected it to the laptop and for 48 hours there are no disconnections so i do not think this is a router issue
After checking logs reason behind disconnection is : the network disconnected by the driver
am up to suggestions since i do not know what to do anymore.
IMHO, the Bluetooth and Wireless driver packages should be installed and uninstalled as a set and Internet access should be disabled so that Windows Update cannot interfere with the update process. Secondly, I have been told to always install the Bluetooth package before the Wireless package. It hasn't gone wrong for me doing it this way.
Hope this helps,
