recently made some changes on old e6400 laptop and wondering if it matters which terminal on the mini card gets the black or white antenna wires?

after swapping the card / ssd with another identical e6400 this one was giving me connection time issues, as well as a exclamation flag for the mini card itself, and as I am running win10, no drivers are available per say.

I did finally get it working, and with the roaming aggressiveness turned to highest [found that tip on here by the way]  the connection issues seem to have went away, but I am still wondering about the antenna wires positioning ?

 

thanks
