Re: Dongle USB

[Patrick Dupre]

Following my previous message

If I use my old dongle, I can easy have 2 PCs accessing the internet
Setting:
PC A has the USB dongle.
It set in Automatic DHCP for the Dongle interface 
and 
Shared to other computers for the interface connected to PC B

PC B is set automatic DHCP

If I do the same with my new Dongle.
It just do not let PC B accessing to the rest of the world.
In both cases, the addresses are the same

PC A
