NUC9i7QNB wifi problem

[kiki]

Hi guys,

I just bought a new NUC9i7QNB board and installed it into Cooler Master NC100. All went well except that the Wi-Fi adapter was really weak. Seems like the antenna was not connected or something because my home Wi-Fi only came out as 1 bar or sometimes even nothing. I test it again my 2 other laptops and my phone as well and the Wi-Fi came out strong on the other devices.
I installed all the updates both from windows and intel as well as bios update. (including intel Wi-Fi 6 ax200 driver)

Could this be something wrong with the hardware? I tried to look inside to find out if there is antenna connection like on the previous NUC but couldn't find any.. (as per the troubleshoot here Troubleshooting WiFi and Bluetooth Issues on Intel® NUC Products)

the system are as follow:

NUC9i7QNB
M1 Corsair 1tb
Corsair 16gb ddr4
NC100
No extra GPU ( I'm just using a discreet intel GPU)

Thanks in advance
