I tried to fix the issue of unacceptable wifi on librem13 by compromising on binary blobs, exchanging the wifi card. Unfortunately one of the antenna connectors was fastened so hard it took some of the surface mounted connector with it.
So now I need to replace the connector on the antenna cable. Or should I replace the whole antenna cable? Where can I get one?
From Wikipedia I see that “The female U.FL connectors are generally not sold separately”.
I upgraded to Intel 9260, and presumably because only one cable is really attached, the wifi connection is slightly worse than before.
