RB133 + XR5

Hi. I have an old RB133 and I want to use it as a Wi-Fi scanner. I wanted to know which PCI card is the most powerful that I can install on this board.
I am a technician who installs antennas in my area of ​​residence. There is a Wi-Fi network throughout the city that provides free internet access.
The goal is to install 2.4 GHz and 5 GHz radios on a tripod with an extendable mast and scan antennas in the area, signal level, etc., and then, if OK, install the customer’s antenna.
Thank you very much.
Greetings.

Use rather Rb433. The rb133 is not further upgradable by newer ros versions.

The fact is I have this card lost in the dust, and I want to give it a reason to be.
I use SXT’s on my customers. I use Nanos, Litebeams and Pharos too.
I have an old Senao 2611 card attached and I’m searching for 5GHz card, all I wish to know is which one.
Theres a R52, XR5, SR5 and UB5, used and affordable.
Otherwise I will go for a new R52Hn.
Greetings.
