Heads up for anyone who may be thinking about replacing the WiFi module in the Librem 5:
While attempting to attach the two wire leads to the SparcLAN module, one of the wires broke off of the snap-on contact at the end of the wire, rendering the phone unusable with WiFi. I do have a small soldering pencil and am going to attempt to repair, but the miniscule size of the snap-on contact is probably going to make this difficult to do.

The end of the cable snapped off? Open the case and replace the cable. See: New librem 5 wifi cable broken
The cables can be replaced, but I just wanted to say that personally I couldn’t bother with opening the whole case to reroute the cables when I was replacing the card in my phone and ended up connecting just one antenna to the card, and it works fine 
Probably not as good as it could with two antennas, but I can’t really complain either.
@dos Thanks for the info. I don’t mind opening the case to replace the cable so I ordered a couple replacements form Digikey. I wasn’t aware that the wires were antennas. So I’m going to use the module with just one antenna until the new ones arrive.
Can you share the link or P/N?
Also those antenna heads are notoriously easy to break and fragile. You really have to try to work with them as little as possible to help prevent them breaking.
