I am running Windows 10 on a Dell 15R 5521 laptop and recently I am repeatedly having problems connecting to the wifi. When I run a windows diagnostic test it says that the wifi apapter has had to be reset. Sometimes it resets it and the wifi connects but sometimes it can't resolve the issue. I have run all Dell updates and diagnostics and it says all is working and up to date. I have disabled the power saving mode on the adapter in device manager but problem still persists. Help please?
