The 8240AI does recognize the Intel WiFi 8265 adapter.
Unfortunately, couldn’t find any WiFi access point.
I ONLY hooked up ONE antenna on the Main socket <=> SMA on the WiFi adapter.
dmesg for iwlwifi which popped out “Direct firmware load for iwlwifi-8265-26.ucode failed with error -2”. The attached file is the test log.
Customer found: center core was bent. And confirm us their internal wireless network recently has trouble. He has tried his phone hot spot, all is good.
And also verified to hook up only main antenna, and left aux antenna un-connected.
I am still able to browse internet without problem.
Please close this case.
