Surface Laptop 3 and Pro 7 hit with slow Wi-Fi bug after waking from sleep

Over the past week, several Reddit users have reported issues with their Surface Pro 7 and Intel-based Surface Laptop 3 devices have suffered from an issue that causes Wi-Fi speeds to tank after waking them from sleep. Microsoft has yet to acknowledge the issue, but there is currently an open thread on the Microsoft Answers forum as well.

According to another Reddit post, the issue appears to be related to how the Intel AX201 Wi-Fi adapter handles connectivity when entering and waking from sleep. When the Surface Pro 7 or Surface Laptop 3 is put to sleep, it disables one antenna while putting the other into a low-power state, which is meant to save battery life. The problem is that the disabled antenna doesn’t appear to be activated and the other remains in low power mode when waking the device from sleep, cutting Wi-Fi connection speeds.

In the same post, the poster, Wiidesire, has posted a potential workaround:

The issue appears to be related to driver version for the Intel AX201 adapter.

Presumably, we’ll see Microsoft push out a fix in the coming days or weeks. However, if you’ve encountered this bug, you can attempt to temporarily work around it by trying the steps above. Importantly, you should avoid installing Intel’s generic AX201 drivers, as they are likely to introduce further issues.

We’ll update this post if and when Microsoft acknowledges the problem and provides a timetable for an update.
