(superseeded) Linuxcnc on Linux Mint 19.3 quick and easy installation

did manage to get Linux mint 19.2 to run from the USB flash drive and the only trouble i have is the WiFi wont work but it seems this is an issue with the USB WiFi connections for what ever the reason might be? works fine with Windows 10 but not Linux? looks like this is going to be the first speed bump might turn into a weekend project since we are supposed to get snow this weekend already

Wifi can be a bit problematic. The one I had needed a driver to be compiled on Debian but when I used it with Mint it was plug and play all the way. It Was an Asus Nano.

But before you buy a new one, post up the name and model of the dongle and also type lsub (or sudo lsub) and report back what it says. we might find a solution.

FWIW in my experience, anything Wifi has affected jitter in quite a bad way.
I got acceptable jitter with a laptop by making sure it's wifi switch was permanently left off and on a desktop box reduced jitter significantly by disabling wifi right from the get go in bios. An improvement from nearly 90,000 down to 15,000.
What I am saying is that when you boot into Linux for the purposes of using Linuxcnc, you may not want wifi active anyway.
To be clear, my experiences are with internal (mboard) mounted wifi, the usb mounted wifi you are trying to get going may be a different proposition.

rod i probably will not mess with it tonight any more but will get back on this for sure. i did not get any documentation on the USB WiFi it was just shipped in pink static discharge bag with the computer when i bought this refurbished Dell. it was not working on the Linux mint so i did not even get the plug and play from the beginning. i tried checking the driver but could not get through it since it was trying to connect to a network which obviously was not going to happen with the issue i am having i will see what i can dig up when i have some extra time. i will have to check your link out some more as well when time permits.not sure if it will show up or not on linux ? but i can at least get the manufacture from windows and let you know that much sometime soon. right now it's nap time i spent to much time today playing around still have one more night of work before i get some free time to get something productive done on all this stuff.

I never used wifi on a cnc pc in the past so if it is problematic it can be left out completely if need be. Only reason i was messing with it was because i use fusion 360 and it is cloud based. But i can just use my laptop for that and keep things separated which is probably better anyways. So your probably right especially since this pc has a parallel port. And if it gets used Wifi will cause problems there.

i played around a little longer with this. what i think is going on is the driver for the USB WiFi is not installed. the USB is from Realteck semiconductor corp. and the chip set is 0bda : c811

i did come across some info on USB WiFi and Linux and this one does seem to work with Linux but i would need to install the driver first.

i looked in the device manager and nothing is listed there so this would probably have to be done some other way?

the only way to connect to the internet is over a wired connection as of now. and the only network with a driver is the wired one.
