I have an external, long range, wifi antenna that I use for picking up internet and I also have a wireless nmea network on my boat for my marine instruments. The problem that I am experiencing is that I must disconnect from my nmea network in order to get anywhere on the internet because when I have both wifi nets active, the Macbook Pro wants to use the nmea network to connect to the internet and it can't. It doesn't matter which way I connect [internet on airport/nmea on external, or the other way around] the internet is inaccessible when the nmea net is active.
Can I make it so that the internet will only come through the external antenna and the nmea net will only come through airport?
Thanks for any help
