ICS through 2nd WIFI Card?

[littletone2002]

So I currently have the Pinapple Mark IV wired to my laptop which is providing an internet connection for anyone who connects to the pinapple. Is it possible to instead have a 2nd wifi card attached to the pinapple that then connects to an AP, and then use this to allow internet connectivity?

Yes, that should be possible with the Network Module. Have you checked it out already?

Yo littletone,

I tried for days to get that to work w/ the network module and the easy point and click was to hard for me. I ended up making my own connection script w/ ipforwarding to get mine up and running. I'll attach it so you can adjust for yourself. Some of it I'll admit was cut and paste from Darrens' mp4.sh script but hey, whatever works right?! :) If someone wants to enlighten me on how to get that Netwok Module working I'm all ears! After hours of messing w/ it I couldn't get mine working at all though.

@petertfm- I saw that writeup. That's also not through the GUI though. I think he and I are doing the same thing I just made my script a little less hard coded and more user friendly. Basically I automated it. I was looking to build something that would work outta the box for more than just me.

I am having a similar issue with the WiFi Manager. Will try this.

I had no problem with the Wifi Manager once I knew what I was doing.

What I did after setting up the wifi connection was to make sure I could reach the Internet by "revealing the public ip" on the main page. Then you just need to go back to the WiFi Manager and set the ICS to from wlan1 to br-lan. Change wlan1 to whatever your card is using. Then you should see the new route appear in the routing table.
