    Having the same issue here. Already sent back 1 XPS 15 9570 and upgraded to the i9 9570. Same issue with poor wifi connection using killer 1535. First XPS 15 9570 Dell sent a intel card but didnt have much luck with that. Hoping for a resolution on this 2nd 9570. Looking forward to a solution.

    Odd, I don't have any issues with my killer wifi in my 9570, or the intel 9260 that I am trying in it.

    all of my other devices, including another dell laptop do not experience this. Wondering if maybe a router/ modem issue?

    Hard to say, the fact that you tried two totally different wireless cards and two totally different laptops makes me think something is going on. Is it just a slow connection or issues connecting?

    Slow connection and sometimes hard to connect to unless within 10ft of router/modem. Further away of 20-30 ft and it is minimal speeds. If I put my other devices same distance(20-30ft)there is no issue with wifi range/speed.

    When I got the first 9570 I thought maybe antenna was bad.

    The thing is, If I am within 10ft, I am getting full mbps of 120+.

    Reset your router lately? Which router do you have?

    It is a CISCO DPC3941T which is what Xfinity supplied me with.

    There was a recall on that wireless gateway due to "performance issues." Call comcast and have them replace it.

    There's a new BIOS 1.4.0 that claims to fix Killer Wi-Fi stability issues. It also adds keyboard backlight timeout settings in the BIOS for battery & AC use (Finally!)
