Check both antennas by connecting them to a receiver and observing signal strength.
Check both antennas by connecting them to a receiver and observing signal strength.
I encountered an issue when installing my card into the mini PC. One of the connectors failed (you heard me right). I fixed it by applying non-conductive adhesive so it could touch the board again. After about six months, I switched to Wi-Fi instead of Ethernet. To verify if the second antenna is functioning properly, you can try connecting a device directly to the Wi-Fi network and see if it establishes a stable connection. If not, the antenna likely needs replacement.
Disconnect the antenna 1. If no signal is received, then antenna 2 was not working.
You likely can swap the card for a socketed version. There are still options like MSATA and M.2 available. I have around three different connectors on my desk right now. Those adapters are not great—I've broken one before installing an antenna, so I'm extra cautious now.
These connectors are only designed to handle a few dozen plug-in and remove cycles, even when conditions are perfect. The adhesive won’t solve the issue, so it’s likely not functioning properly. Unless you’re comfortable with soldering small surface-mount components, consider swapping out the module.
Completed the job, but the glue didn't stick properly. Added another card, but I need to understand what the "e" means since this new one lacks those pins. Also, I had to switch antennas because the cable was damaged at the socket—wondering if that affects performance, as the connection is now significantly slower than before with just one antenna.
