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

[poorestguy]

Hi guys,

I'm having trouble trying to get my wireless and lan connection to work concurrently. 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?

Problem relates to network manager which only handles one connection at a time. You can disable it and manually setup your connections.

Is something else on the LAN acting as a DHCP server? NetworkManager can only handle one interface at a time (unless that's changed recently), so you'll have to configure your LAN connection manually and give it a static IP.

no i have set up a static ip.its a direct cable connection with my ps3.i set up my 3g (cell c) and lan connection manually so yeah not sure how to go about this

I know this isn't the answer you want, but I'm really enjoying one of these:

I don't have a linux box that I can test the NetworkManager stuff on, otherwise I would have looked into that for you.

poorestguy,


If you want to use 2 network interfaces at the same time you first have to configure them each to do the specific job you want them to do.
If 1 of the interfaces is for the LAN only then dont configure it with DNS or a gateway, also make sure it is on a different subnet, then let your 3G handle your internet connection and connectivity to the outside world.
You should also look at static routing, it's a way to tell a service or device where to send its information instead of leaving it to go through the default connection.
