Intel Wifi 5 201ax 160Mhz cannot see wifi on certain channel (U-NII-1, channel 36-48)

[gielvandanu]

I have lenovo e14, it has Intel Wifi 6 201ax 160Mhz card. running on windows 11. using the last update,

I have problem for wifi channel, if I set my wifi network at channel 149-161 it works flawlessly.

But if i set using the wifi using channel 36-48, it cannot see the wifi.
Newer Lenovo e14 has intel wifi 6e 211ax 160Mhz can connect to the wifi whatever channel I set

What am i missing here?

Hello gielvandanu,

It seems that you are experiencing connectivity issues as the Wi-Fi adapter is unable to detect certain channels. I'd like to get the information below to address this correctly.

1. Were you able to connect to channel 36-48 before?

2. Which driver are you using?

3. Is this the original adapter that came pre-installed in your system, or have you changed/installed a new adapter recently?

4. Have you modified any WiFi adapter settings before issue appears?

5. Have you rebooted your access-point, router, modem?

Additionally, to have a better understanding of your system configuration and components please generate System Support Utility (SSU) report. Please follow instructions here and send the report - How to get the Intel® System Support Utility Logs on Windows*

I look forward to your response.
