Question

Which internet connection takes precedence?

Something that many people will not come across with often, but I do. I have 3 different types of internet connection available: LAN cable (from modem to PC); Wifi (from the hotel where I'm staying); and even a USB aircard (data connection)

The question is, if I am connected to all three, how do I know which connection I'm actually using?

Right now, for example, when I connect to my USB card, I disable the LAN connection and I don't want to do that every time.

Thanks!

Doesn't each one

have a separate connection set up for it? You could also run IPCONFIG in a command box.

Likely the last connection made.

But as this is all about IP Networking which takes about a quarter in the classroom and even then folk have a rough time with it, you can't be sure given the software today. You must use the NET ROUTE print command to see what the routes are. Then, for many that's just too technical.

Unless you have time to learn IP networking I think your way is best.

Good point Bob, but...

...what about if at start up all three connections are open?

I guess the question really boils down to whether I have to disconnect or disable the other connections before I choose one of the three? ie. without having to check the ip addresses after the fact.

Let's be even more specific: intuitively, the LAN connection would seem to take precedence?

Thank you both.

Then I need to look at NET ROUTE PRINT output.

Given today's software I will never write it's certainly this or that.

If you wonder why I answer this way, I wrote router code in the 90's so I know a bit more than I let on. But today I see apps that can tinker with the tables so to be sure I have to read NET ROUTE PRINT (that's the words for google) to see the routes.
