Lowrance HDS help

[C-Bass2mouth]

Ok, got a new HDS gen2 Touch to replace the previously mentioned HDS gen2 that crapped out on me. Here's my next question.

I just got a new Ethernet cord to network the two units. I'm also thinking about buying the GoFree Wifi module and linking an ipad to one of the units to mount at the console also (cheaper than buying another HDS). If I were to do this, could I run an Ethernet cord from the wifi module, and both HDS units to the LSS-1 box and use that as a networking point? I have a push button HDS gen2 7 at the bow, with a Touch HDS gen2 7 at the console. I know the Touch has the LSS-2 built into the unit itself and has no need for the extra box, but if I were to run an Ethernet cord directly from one HDS to the other HDS, I'm all out of Ethernet ports (yellow plugs). So then I wouldn't have anything to plug the Wifi module in to. The LSS-1 box has 3 Ethernet ports.

Thanks,
