Hi:

 

Normally there is only one antenna cable connected to the Realtek RTL8723BE 802.11 bgn Wi-Fi Adapter.

 

A dual band wifi card requires two antenna cables in order for it to work properly, if at all.

 

So, if your notebook has two antenna cables, you can upgrade to one of the dual band wifi cards listed in the service manual for your notebook.

 

If it only has one (which it probably does), then you cannot upgrade the wifi card.

 

It is not feasible to add a second antenna cable, since you have to completely disassemble the entire notebook including the display panel to properly install the second antenna.
