Killer has released a driver update for its wireless card that appears in the new Dell XPS 13 9360 and Dell XPS 15 9560, offering up a fix for a particularly annoying connection drop issue plaguing some users.
As we noted in our XPS 15 9560 review, the wireless chip worked normally through things like basic web surfing and video streaming. However, once you put it under heavy load, the issue would cause your connection to drop:
For example, say you are downloading 70GB on Steam and decide to browse the web or watch YouTube. The Windows 10 Wi-Fi indicator will get an exclamation point and drop the connection, then get a red "X," and finally cycle back on. The process will repeat. It's annoying even if rare.
This driver update is for all devices running the Killer Wireless AC-1535 including the Dell XPS 15 (9360) and any Razer products as well. Those companies will push the driver through their own update channels soon, but you can update yours now if you like to fix any issues.
Interestingly, the original problem was caused by an update by Microsoft that broke some functionality in the Killer card.
Thankfully, after some time in beta testing, that issue should be cleared up with these new drivers. If you have an XPS 15 9560 or any other device that uses the Killer AC-1535, you can grab the latest drivers direct from Killer at version number 220.127.116.110.
