I am currently using a Killer 1635 wireless wifi card on my dell xps 15 7590. The problem is that when i am on my 5GHZ or 2.4 GHz wifi, the wifi tends to disconnect often. When the wifi disconnects i am still able to see my available wifi, lets just call it house_5G. Once disconnected if i try to connect right away it says i am unable to connect to the wifi so i have to wait around 30 seconds before i am able to connect again. Also i know this is not a hardware issue because i actually just got a replacement for my laptop and i kept them both for a bit before i sent one back, it is not a hardware issue because i noticed that both laptops decided to disconnect to the same wifi at the same time, on one laptop i wasnt doing and thing and the other laptop i was watching youtube. All help is welcome
