My Intel dual band wireless ac7260 on dell latitude e7440 year 2018 model, working in full force but not connecting to my home xfinity internet 5g, while it is connecting to my tmobil hotspot from my phone including other internet services outside my home. I tried to download drive from intel website but it said no supported drive available but running in full power while using my T-Mobile hotspot. Any ideas why it is not connecting to my home 5g wifi?
