Wireless Card Compatibility

[nostomach4cancr]

Can I upgrade my wireless card to the Realtek RTL8822BE?

Will my existing antenna connectors work?

If not, can I move to the Realtek RTL8821CE?

Hi:

You can replace the single band Realtek 8723DE card you have in there now with the RTL8821CE 1 x 1 AC wifi adapter because that card is designed to work with the one antenna your notebook has.

The 8822 2 x 2 AC card needs two antennas to work.  Here is a picture of the 8822BE, which has two terminals for the two required antennas.

Can an additional antenna be added so that I can upgrade to the faster 8822BE?

If you want to literally take the entire notebook apart including the display panel area, to run the second antenna, yes, that can be done.

You would have to order the dual antenna kit. Chapter 3, page 21, item 7. 

And you will have to know whether or not your notebook has the narrow bezel or the standard bezel.

How fast is fast? 

Unless you are paying for 1 GB download speeds, or do a lot of large file transfers from one PC to another within your home network, isn't 433 MBPS enough?

I have a 200 MBPS internet service, so any wifi card >200 MBPS is good enough for me.
