Have you thought about just getting a little linux mini on Amazon?

I got 2 cybergeeks and so far anyway they seem to work pretty well

although I have not had them long enough to tell how reliable or defective

they may be. I'm to turn one into a wifi-repeater so I can intercept 
drone to

phone communications and the rtsp image stream but if you have any

unusual needs the versatiliity may be useful. I can't get the bridge to work

with nmcli yet and I had a bizarre problem with an ASUS router sending 
all my

ip's to 10.0.0.1 but the computer itself seems quite capable. And if you 
don't

want the firewall you can use it as a computer lol.

Getting it to work as a router was quite easy and I have 2 ethernet jacks

and builtin wifi as well as a cool usb wifi. The problem though is again

simple things like making the repeater work with just nmcli and not hotapd

etc.  If anyone has a one liner for that it would be appreciated. Thanks.
