SER9 serious wifi and BT issues

Frosch1482

Hi,

my SER9 startet to be unusable.
since a few days, Wifi and BT are not reliable. Wifi drops for no reasons, reconnects with very slow speed telling me “no internet connection” a restart somtimes fixes the issue, sometimes not. Wifi is definetely not the problem, because any other device is working flawlessly.
the device manager tells me that he stopped BT because: “Windows has stopped this device because it has reported problems. (Code 43)”.

of course drivers are up to date. latest from intel via Intel® Driver & Support Assistant

I assume that I have a defective Wirless card…

Any suggestions?

Hello there,

Sorry for the trouble.

Could you please send us a picture of SN code(two lines) at the bottom of machine ?

It is suggested that you try resetting the WiFi network card. Here is the tutorial: https://url.bee-link.cn/sF2l

If the problem persists, it is recommended that you try reinstalling the system.

It is recommended that you can go to Microsoft official website to download the corresponding win11 PRO system file to install, this is the tutorial: https://url.bee-link.cn/74zu

Please remember to backup the data.

Have a nice day~

I don´t see why a fresh install should solve the issue. Once I recieved the device I did a fresh install. Do not trust the preinstalled windows ;)
will try to remove the wifi card and put it back together.

Hello there,

Sometimes, it might be due to incompatibility between the system and the machine that causes the WiFi and Bluetooth drivers to disappear, resulting in the malfunction.

We will wait for your reply after you have attempted to solve the problem.

Have a nice day~

Hi,
I tried to remove the drivers. Reinstall them directly from Intel.
Then I tried to remove the intel drivers and use the windows once.

Of course I tried to remove and reinstall the wifi card as suggested. I tried external antennas as well.
I did a fresh install of win 11 pro as well.

Nothing helped. I´m still sitting here with a BT issues

This device cannot start. (Code 10)
STATUS_DEVICE_POWER_FAILURE

What´s next? don´t want to buy a new wifi card by my own for a 1k EUR mini pc…

We suggest that you contact our after-sales email address - support-pc@bee-link.com.
We can apply for a machine replacement for you.

Would you be willing to send the machine back to China for testing?

Do you by any chance use the HDMI port? I disconnected it and my wifi connection is literally 10 times better.
