Losing WiFi signal when in clamshell mode

I recently bought an M2 Pro 16" MacBook Pro. My router supports WiFi 6 so I'm in a WiFi 6 network. I use my Mac in Clamshell mode most of the time connected to two external monitors. Since yesterday my WiFi signal becomes unusable while the Mac is in clamshell mode, opening the lid instantly fixes the issue. Is this something common or expected? I'm still able to return the unit and get a new one but before doing that I want to make sure that there is indeed something wrong with this particular Mac.
