That system will support CNVio.  Did  you remove the existing network drivers for the old card before you shut down to do the upgrade?

@ejn63​ no, that I will try next week. I am somewhat sceptical, as the drivers of the ax211 are the same as the be201...

@miloman1959​ 

hi, Did you fix the issue and get to use the be201?

@rodrigonbr​ no sorry, did not try to install it again. I will report back if it works, since there have been a few bios-updates. And I still feel this card should be supported...

Did you try it?

@miloman1959​ 

I bought the BE201 without researching compatibility. Your comment made me nervous. Still waiting for delivery, but as soon as it arrives I'll test it and report back. I'm worried, though.

I might just switch to the BE200. My AX211 is giving me trouble. Not sure if it's the hardware, but I'd rather test a new card than sell the whole laptop.

@rodrigonbr​ my ax211 is working fine, just for your information. 

You are on the latest bios (december 16th 2025)? Hope you get it working. The be200 is the alternative indeed, but I am hoping the be201 will work at some point.

I remember that some 5450's had issues with wifi because the antenna came loose, because the cables running from the screen to the mainboard were too short. That might be the culprit...

having trouble with Bluetooth headphones on Teams. Updated all drivers and BIOS, reinstalled Win 11, but nothing fixes it for good. My last hope is switching to a BE201 or BE200. If that fails, I'm getting rid of my 5450.
