Routing internet through 3G, printer through WiFi?

Hi,

We have a small case for a client who wants a WLAN at their premises - but would use it only for LAN. They would attach printers and other equipment to this network, and use a 3G dongle for surfing etc on their few laptops.

WiFi probably takes preference over 3G when a laptop connects to it? Would messing around with lowering the 3G metric only make the computers also try to print through it?

Is the only option to retain internet connectivity and printing ability (with this current setup) to enable WiFi only for printing?

Could you add a "route print" output with a 3G dongle connected to internet?

hi,

can you give the private IP addresses use for the Wifi network and printer?
i believe if you don't configure a default gateway on your wifi adapter and the network are differents, the computer should use the 3G connection for internet but the wifi network to print.
regards,
Yannick

WiFi without default gateway sounds like the right solution, didn't think of that. :)

Too bad the client went back on the deal so can't test it right now. Should try it though!

Same problem here, but android doesn't allow you not to set a default gateway.

Any solution for android devices?
