Okay, I'm thinking of getting the Netgear WAX202 for wireless and adding ports for ethernet when it goes on sale, apparently it's been as low as $30 USD. Not sure I can get that pricing where I live but I'd like to hold out for a good sale.
I found this post about building where you download the patches and then use git apply with the commit hash before make menuconfig. Would those instructions work for me if I did want to try installing the broadcom drivers on the ROCK 4 anyway?
