    Slow wireless speeds with Intel 8265 ac card under windows 10


      We have 2 Dell laptops (Latitude 7490 & 5580). Both have the Intel 8265 ac wireless card installed. Both are running windows 10.


      Both have been experiencing extremely slow wireless download speeds. By slow I mean less than 1mb down. Upload speeds appear to be fine. This problem occurs on any wireless network (users homes, our work, Starbucks, etc.).


      Changing the MTU from 1500 to 1400 on the card worked for about a week, Now their speeds are slow yet again.


      Wired internet works fine.


      Dell replaced one of the wireless cards and the speeds are still slow.slow.


      Both are using the latest Intel drivers.
