Add information about running WiFi and Ethernet together

[edpgcooper]

I have both interfaces connected (my device has two IP addresses), is it smart enough to prioritise Ethernet for Helium traffic when it's available? If not how do I stop it using WiFi without a total reset?

Interesting question. The network is managed by Network Manager behind the scenes. It is certainly possible to run both WiFi and Ethernet simultaneously, but I'm not sure if Network Manager is intelligent enough to prioritize properly. I know that macOS will automatically route traffic over Ethernet if both Ethernet and WiFi is present.

This would be relatively easy to test, but I cannot personally allocate the bandwidth for it at the moment.

One thing I also wondered, is whether having both simultaneously connected can cause any issues with libp2p successfully communicating with peers...?

I've actually tried many times to clear the WiFi credentials from the device with zero luck - perhaps some clarification is needed as to how you can remove the WiFi credentials when you just want to use Ethernet

I set up separate policies on my Fortigate firewall for traffic on 44158. One coming from Wi-Fi, the other coming from wired Ethernet. Placed them before all other rules so the counters would reflect traffic. Tested with a Nebra hotspot. I plugged it in, cleared all logs, and plugged the Ethernet cable in shortly after. Pay attention to "Bytes" at the very end of the image.

Couple minutes later:

From a different view. Wifi Hotspot Traffic should appear.

Now I will unplug the Ethernet cable.

Back to wired.

I was not seeing traffic from the wired and had no ethernet lights, so I rebooted.

Suspect it was a switch security setting that caused the port not to light up, so trying again. Switching back to wireless in the next picture.

Wired comes back, and the sessions have dropped from Wifi.

Port stayed online this time. As seen above, I wasn't seeing much traffic on Wired. I reset the ipv4 policy counters:

Works as expected, from this point of view.

Edit: I switched my PC's port with the hotspot, and the same port went offline for no reason. The switch was the reason it didn't work correctly the first time, it seems.

I would love easy way to remove the wifi from being listed in my router
