Need to use both wired and wireless at same time


I need to connect the ETH0 to a device for config. I need to use the wifi to connect to phone or router to download/upload files. What do I need to do to the network manager to make this work?

As long as they aren't on the same subnet there's no problem, just plug it in, set up a static IP on either or both networks as necessary, and make sure your wireless gateway is listed as the default.

If you simply want to configure a device then there are some ways to get around the issue. Making a static arp entry for the device would force an ip address on it.


A common way is to use a combination of IP address, subnet mask and gateway address to route traffic out of correct nic. As stated above this seems to be the correct solution from what we know.

I guess you could do some wild stuff too that is a bit out of the usual.

I usually have 32bit laptops available for field work and tend to put Lubuntu on them for continuity. I've noticed that recent updates the network manager doesn't seem to work as well as it used to. I've got a unit right here that was just installed with linuxMint 17.3 32bit. (I broke the install by trying to install Connection Manager and wicd, couldn't get vpn to work at all) My usual setup is to assign an IP and subnet to the laptop first via network manager. I save these by name so I can just click on them as needed. I've noticed this doesn't seem to work with 16.04LTS, maybe I haven't fiddled with it enough, or maybe there are some items in the repo for network manager I need to download?

I connect with the rj45 to device under test and if I need to fetch a file from the internet, I like to grab it via wifi, sometimes that's the only way I can get to the internet is via tethering to an Android phone.

Jefro, please send an example of what you had in mind

Say you have to replace a gizmo that has management port default ip of 192.168.1.1 but your lan is set up at 10.10.10.x.
You set a static arp entry from the mac address on the gizmo to be a 10.10.10.x When you type in the browser the 10. address you get the default config of the gizmo. Be sure to remove the static arp when done. It will be heck to figure out later.
