Hi @hpbrian ,
The pins are actually co-axial cable connectors which connect the 2 wires (signal wire and shield) in each of the cables to the connector on the WLAN card.
Because it is an electrical circuit “gluing” will not work (it needs to be soldered or crimped properly) and “pinching” the wire means that you won’t get to the inner conductor of each cable.
If the connectors are not connected properly to the wires as far as an electrical circuit is concerned i.e. no resistance joint and no connection between the two wires in each cable then the WiFi will have diminished performance as far as distance from the network access point and stability of the WiFi connection
The best DIY solution is to replace the WLAN antenna cables.
Here’s a link to the maintenance and service guide for the laptop, taken from this webpage.
Scroll to p.65 to view the necessary pre-requisite steps and then the procedure to remove/replace the WLAN cables. Also at the top of p.65 you will find the part numbers for the cables.
If you search online using the part numbers only in the search term of your browser you will get results for suppliers of the part.
