Sorry in the title I meant use NO data.

If I have a USB tethered phone always connected to my computer while I also have a wired network connection, will the phone use data when I load webpages, download things, etc?

I gave the wired connection #1 priority from here:

Does anyone know if that's enough?

It should not use the phone connection at all. If you have not messed around with the routing there are only default routes and it will always pick one or the other.

Issue the command route print.

You should see 2 routes to 0.0.0.0. The one with the lower metric is the one that will be preferred.

You can always issue a route delete for the 0.0.0.0 route to the phone connection.

That is pretty much all you need to do. What you have is 2 different default routes one from each network. The PC likes to only have a single BEST default route. It users the interface metric to select it. Your other option is to remove the default route from the interface you do not want it to use completely.

Now if you actually want to use both at the same time you can use the ROUTE ADD command to add routes for particular sites you want to go over the tethered connection. Gets very messy fast if you try to do too much but it does work well.

To get it to switch you would have to actually unplug the ethernet or manipulate the metrics or default router to get it to change. Unfortunately you can completely disconnect the internet from your house and the router will still be in a UP condition as far as the ethernet port is concerned.

Hmm, I have the phone's network at bottom of that list. But if I load a webpage with both networks connected and look at the status, the phone's download number is increasing at a much higher rate. Shouldn't it be barely increasing at all when compared to the 'main' connection?

I set wlan as priority, but it uses also my thethered mobile internet as well, how is that? Unfortunatelly, My mobile internet is limited, I only want to have it as a backup, because sometimes wifi is unreliable. So sounds like the same, how did you solve it?
