Windows behaviour with multiple internet connections

My ISP is having some connection problems tonight. To get some daily gaming activities done on what I hope was a more reliable if higher latency connection, I dug out my backup mobile connection and used that for a while. That is USB connected and appears to the system as 21 Mbps Ethernet. The regular network connection is seen as gigabit Ethernet, with ISP speed somewhat lower. With both present and working, I see internet traffic goes over the gigabit connection. Only if I disable the wired ethernet does it use the mobile connection. Is it as simple a case as higher bandwidth = better? Is there some way to influence the behaviour of this, to make the mobile connection 1st choice for example?

 

I vaguely recall seeing similar on routers while doing CCNA, but have no recollection of what it was called, or if Windows does it.

You could adjust the metric for the interface. Lower is more preferred I believe.

I know for connection defaults Windows prioritizes wired over wireless so it's probably wired > wireless > usb (or something to that effect) but you can change that as I mentioned by manually setting the metrics for each interface. I think Windows will default to link speed with the faster link being the better metric as well if you have two wired connections (eg: 10Gbps and 1Gbps)

You can change the route on the route table manually in command prompt, you'd just give the wired side a lesser-preferred value.

Ok, it's giving me some PTSD but 192.168.0.1 is my wired ethernet, and 192.168.1.1 is the mobile connection. Lower is more preferred metric if memory serves me right. I might play some more with this later... and wonder if I can do some weird stuff e.g. with dual parallel network, prefer one for internal traffic and keep the other for external?
