How to fix Killer Wireless 1535 driver issues on Windows 11

What is Killer Wireless 1535?

The Killer Wireless 1535, developed by Rivet Technologies and later acquired by Intel, is a WLAN or network card for gaming-oriented systems. The Killer Wireless card list boasts a long list of features, including Bluetooth 4.1 and dual-band support for 2.4GHz and 5GHz.

Killer Wireless is based on Qualcomm chips and features ExtremeRange technology for wide connectivity, minimal packet loss, and minimal latency when playing multiplayer games.

Why is Killer Wireless causing driver issues on my PC?

Killer Wireless’s problems are not new. It has caused problems for multiple users on Windows 10 over the past few years, and switching to Windows 11 seems to have made things worse. According to the Killer Wireless website, their drivers do not support Windows 11 at startup, which has caused driver issues for many users who switched to Windows 11.

The series also faced limited support after being acquired by Intel, and the initial support page detailing fixes was completely removed from the website.

Microsoft also mentioned that this may be due to a network bug on Windows 11 affecting UDP. Outdated drivers and lack of compatibility patches between Killer Wireless software and Windows 11 can cause major driver issues.

How to Fix Killer Wireless 1535 Driver Issues

The following is a list of known fixes to fix Killer Wireless 1535 driver issues on most systems. We recommend that you start with the first few known fixes and work your way through the list until you manage to get Wi-Fi working on your device again. let's start.

If you have access to the Killer Wireless Control Center, then this is the recommended fix for you. Wi-Fi Priority is a feature of Killer Wireless Control Center that uses Intel's Priority Engine to identify ongoing network requests and prioritize them based on your current needs and requirements. This helps your network adapter automatically handle your multiplayer game connection needs first, and then handle background network tasks.

However, this priority engine does more harm than good. Most Killer network cards seem to be facing issues with this functionality on Windows 11 due to outdated drivers and limited support. Therefore, we recommend that you disable this feature and reboot your system as early as possible. If you purchased a gaming laptop a few years ago, then this is most likely the cause of an issue with your wireless drivers.

To start Killer Wireless Control Center, just turn off the "Priority Engine" switch in the quick settings widget. You can also turn off the priority engine by clicking on it at the top. After shutting down, restart your system and Wi-Fi should be back up and running on your system again.
