The DC jack port on my Asus Zenbook Prime UX31A broke recently and I had to perform some very fiddly surgery de-soldering it and soldering a replacement, which cost me £3 to do myself rather than £60 or more in a repair shop.
Unfortunately after getting all excited that I managed to do the hard part successfully, I proceeded to break the connection clip on one of my wifi antenna cable and I need some advice.
I have included a picture for reference, as you can see the cable that connects to the aux antenna port is the one that's busted. Currently I can connect to my 5 GHz router and use internet just fine, bluetooth works as well.
So my first question is what does that second antenna even do, I assume it is some kind of load balance for improving signal quality. Can I live without it?
Second question, is it a coaxial cable, and more specifically does the outer shield need to be wired up for it to work if it is a coax? The connection terminates in a metal clip that makes me think that it may be, also the female connection has a metal inner connection and outer connection (see the wifi chip in the pic)
The reason I ask this is because I have other laptops laying about that I can butcher to get at a fresh antenna cable tip. I back my soldering skills to a point, but I don't think I would be able to solder such a small cable if it were a coax, marrying up a core and a shield at such small scale is beyond me.
