Wi-Fi with awful perfomance after update 23.110.0.5

[athosmoreno]

I have a Samsung Galaxy Book 3 360 laptop with an Intel AX211 Wi-Fi. It always had awful performance but with some tweaks in driver configuration I made it work more or less. Now, after the last update, download/upload performance is abysmal compared to other devices in my network, and all the tweaks that worked doesn't seem to have any effect.

Is there any known workaround or just pray for it to be fixed?

I don't really remember the previous version. I did everything via Intel Driver & Support Assistant, which installed automatically. 

The speed is really slow. If my phone is having 150 mb speeds, the laptop is under 30, side by side.

I also tried uninstalling and then re-installing the driver but it didn't changed anything.

Hello athosmoreno,

Thank you for sharing this useful information with us.

I just want to confirm when you reinstall the wireless drivers, did you perform clean installation?

• You can check this article on how to perform wireless clean installation: Clean Installation of Wireless Drivers

My I also know if your connected to 2.4Ghz or 5Ghz.

Yes. I uninstalled the previous driver on Device Manager and installed it again via the executable installer.

My wireless network works on both frequencies, the laptop is always on 5 GHz. I use two Huawei AX2S routers.

[athosmoreno]

I decided to move my second router. It improved the speeds on my laptop under the coverage of that router (both routers are connected in a wireless Mesh), but it still underperforms other devices (my mobile and my corporate laptop) in the network.

Hi athmosmoreno,

Thank you for patiently waiting.

Try configuring your laptop settings to use the settings from: Recommended Settings for 802.11ax Connectivity.

Have you already coordinated with your access point manufacturer if they have any recommended settings to ensure that your devices have optimal connection with the access point?

Windows Update ended up updating the driver again. I have been using it since and noticed a new behavior.

I turn on the laptop and use it for a few minutes, then the connection suddenly drops. Then it falls back to a backup SSID that my router provides that has only 5 GHz (but not Wi-Fi 6). Then it works fine on the backup network.

But it feels weird that the laptop doesn't play well with the Wi-Fi 6 network since the Intel board has that.

[VonM_Intel]

Hello, athmosmoreno.

It's interesting that your laptop drops the connection on the Wi-Fi 6 network but works fine on the 5 GHz backup SSID. Since the Intel board supports Wi-Fi 6, this behavior definitely seems unusual. Since Windows Update reinstalled the driver, please verify which version is currently installed.

Windows Update had it updated back to 23.110.0.5. However, I turned on the laptop today and the Intel driver software notified of an update for version 23.120.0.3. I just installed it and will update on how it goes.
