Hello the m2 wifi adapter which came with the jetson orin nx does not work. I have an usb wifi adapter AWUS036ACM which is said to be supported out of the box by ubuntu. The os can see the adapter when running lsusb however the ip a does not show the wifi card.

Is there any way I can make this USB wifi card working?

Hi,
Do you mean the RTL8822CE WIFI/BT module does not work? It is supposed to work on Orin NX module + Orin Nano carrier board + RTL8822CE being inserted to Key-E slot.

Well, the thing is I am unable to put the antennas on the board and without them the signal is very poor it looses the connectivity even though the wifi router is in immediate vicinity. I needed something else like an USB dongle that does not have that problem. That is why I purchased a mediatek mt6712u. I tried to build the modules in the kernel for it. But unable to find the kernel source for the jetson.

Hi,
It should be no issue to connect antennas to the RTL8822CE WIFI/BT module. We don’t face difficulty on developer kit.
For module from 3rdparty, please check with the vendor to enable the driver. It is K5.15 with Jetpack 6 and you can check developer guide to do kernel customization:

Shall I download the driver sources?
