How can I configure my vista notebook to access the internet by WIFI
and my local network by cable ethernet? When I have my wifi activated
it seems that the LAN has priority, but i'd like it to be the other
way. Is it possible?
 
If you have multiple routes to the network then the system will spread the
packets out between them to optimize data transfer.
Because the LAN probably has a higher speed, the system will try to send
data that way if possible, and use the wireless as the LAN channel becomes
jammed. If you want to change the priority in order to slow your system down
you can do so by changing the parameter 'interface metric'.
Normally this is set to automatic and is determined by the system based on
throughput on the available interfaces.

View status of each of your devices, (from network and sharing center for
instance).
Select properties
select properties for IPv4
advanced button
on IP settings tab, unselect Automatic metric and type in a number in the
Interface metric box. The smaller the number, the higher the priority.

I'm going to try reversing them. The problem in fact is that with the
LAN connection we have a proxy server, but with WIFI we do not. So if
I put WIFI was higher priority, it'll work for the internet. but what
about the access to the local servers? It'll try WIFI first and fail
(they're not available to the WIFI network) and then will it try the
LAN connection or just give up? If it tries the LAN connection then
that would probably work for, although local access might be slower
especially if it waits for a timeout.

I was hoping I could set up the routing so that all local requests (I
think all of ours are 10.0.x.y) are on the LAN and all others are on
the WIFI. Is this possible? I think it'd be more efficient.

Thanks
 
My assumption was that each hardware interface can get to the same places,
just that some paths are faster than others. I have no idea on how Vista
behaves if some destinations are available only on some paths.

I was thinking you were trying to reduce your machine's impact on the wired
router.

With the clearer understanding of the goal hopefully someone will be able to
chime in with advice!

as to the second part of your reply:

any access to 10.0.x.y will certainly go thru that LAN, however I don't see
how the DNS works across multiple networks.

If you check in the DNS tab of advanced TCP/IP settings you will se a box
where you can put the order of use for DNS servers.
It MIGHT be that if you put your local DNS server address first and the
Wireless DNS server second, then if access to the internal LAN could (or
would) not locate the destination, then would fall to the Wireless which
would then work. I am pretty sure that it is this area you want to play but
way too many options in that window that I do not understand.

For your first part, it depends on how you have your routing setup.
You can route traffic to a certain IP network via a specified
interface with the Vista route command.
