how to get the 3g and lan connection to work at same time in Ubuntu 10.10?

[poorestguy]

Hi guys,

I'm having trouble trying to get my wireless and lan connection to work concurrently in Ubuntu. When I am using my 3g netwok then want to use ps3 media server to stream to the tv it just doesnt work! As soon as I disconnect the 3g connection then it works fine with no issues. Surely there is a way where I can surf on the net and use my lan at the same time?

give output of , route and ifconfig when you connected to both

Are you still struggling with this poorestguy?

When you connect your 3G, it sets a default route for all traffic to go via 3G. Traffic to your local LAN should still work as there should be a network-specific route for it, but if your media server's on another subnet it won't see it. The fix is to add another network-specific route.

hey..nope still havent sorted the issue the issue is i havent added any subnets manually except for the lan, and the cell c 3g connection creates setting synamically as it dials up.how do you add a specific route to differentiate the traffic?

To expand slightly on what Grim147 asked for: give the output of

route -n

and

ifconfig -a

when you're connected to both

Then it will be easy to say what extra static route command you need.
