Linksys WPC11 ver3 firmware upgrade?

Hello: I am trying to get a wireless connection to my J728 running Devuan using a Linksys WPC11 (v3) PC Card, as in this video:



My missing step is to have the firmware updated (to 1.8, my current version is 1.4).

Does anyone know the commands/scripts needed to make this upgrade? It appears it can be done from within Devuan itself.

Thanks in advance for any pointers!

I found this page

But, I don't recommend doing it unless you do more research too. I wouldn't want to risk you screwing up the card due to my lack of knowledge. I just found that post so we get perhaps closer to the answer.

I also don't know if these steps work on Devuan anyway
