Preferential order of networks

[Sipper]

Hi Guys

I have a small home network all connecting using an AEBS and ethernet cables. There is also a cable modem connected to the WAN port of the AE using an ethernet cable. This all works perfectly, however :-

In my bedroom I have an ADSL line connected to a buffalo router to which is also connected a cable TV digibox. If I want to connect to the digibox I am able to open Airport on my mini and connect wirelessly to the buffalo router no problem, and from there to the digibox.

The problem is that when I use airport my mini takes the adsl line as the preferred internet connection which unfortunately is a lot slower than my cable setup. The easy solution would be to disconnect the adsl line but thats what I let visitors log into instead of sharing my apple network.

My question is therefor - is it possible to have the ethernet connected internet connection as the preferred network and the wireless network as the fall-over or backup network?

many thanks

Sipper

You can change the order in your Network Preferences. You simply need to drag Ethernet to the top of the list. Then put AirPort in the number two slot.
