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?
