Hey, thanks for the response, yes I replaced old antennas, but I ended up getting this particular model:

The long green antennas were not small enough to fit inside the chassis, but the red ones fitted properly on the same places where the old antennas were before.

Just remove the protective tape and stick antennas to the plastic, it's easy to do.

The hardest part was to attach the antenna connectors to AX210, I used a small piece of plastic to gently push the connectors to the installed adapter until it clicked, it could take some time but be careful not bent the wire too much.

So it's kinda tricky but definitely doable, and now I'm very happy with the wifi connection speed and overall stability, no issues at all.
