Slow wifi after Instant On wake up

Question

Hello,

I just acquired a Surface Laptop 3 13.5'' and I noticed that wifi becomes (way) slower after waking up from sleep mode. A speed test shows a decrease in the order of 90% (from 100 Mbps to 10 Mbps).

I am not alone (a couple of posts on reddit deal with this issue) and I think it affects all the new Surface devices with Intel Wifi 6. Is Microsoft aware of this issue? Because it makes Instant On feature completely useless if it costs 90% of wifi speed.

Note that I don't have issue with Ethernet.

Thanks.

Answer 1

I have used Intel Driver and Support Assistant, I have installed the following:

Wifi Driver:

WiFi_21.60.2_Driver64_Win10.exe

Buetooth Driver:

BT_21.60.0_64_Win10.exe

I have not had problems with the Wi-Fi connection again.

Answer 2

I did the update via Intel but it did not work for me. I had to roll back the version.

Answer 3

Is the update still stable? Also was it via Microsoft or via Intel? 

Very hesitant to install any updates. The patchwork fix of tweaking MIMO settings has the wifi somewhat stable (though not at full capacity) so I don't want to break it but it would be nice to get the speeds I pay for...

Answer 4

The new Intel drivers 21.60.2 resolve the issue for me.

Did not work for me. Brand new 10th gen HP Spectre x360 2 in 1. Done with this **** show. I think the problem is hardware based with the AX201 and cannot be fixed. This has been going on since October. Plenty of time by now to fix it. My advice. Avoid any and everything that has this faulty Intel AX201 wifi 6 card in it.

Answer 5

The new Intel drivers 21.60.2 resolve the issue for me.
