Not the wifi card, the surround material like the chassis are attenuating the signal (the librem 14 should have fixed this issue). I swapped mine out for a well supported and performant Intel card and only got marginal improvements to the signal.
My "ten feet" was using it at coffee shops. I was traveling with the laptop. It was hard. The card switch did get it over the hump for this use case. Not an issue most of the time but still will have get a spot closer the router for video calls (like standup).
So the constraints for work were getting a seat close the router AND a power plug. I ended up USB tethering with my phone alot.
I do appreciate their contributions to the ecosystem but was wronged as a consumer. They need to be truthful.
I take it you have the v3 with the standard boot drive?
