Okay so, I got a new router today, Airport Express. Yet here's the big problem with it.
1. It's a bitch to get it to loving work on my mom's computer
2. When I try to set a static IP Address through airport utility it breaks my internet connection.
I set the 3 computers in my house different static IP's.
My dad's 10.0.1.3
Mine 10.0.1.2
And I tried to set my mom's to 10.0.1.4 YET. IT DOESNT loving CHANGE RIGHT.
What happens on my dad's and my computer is this:

But what happens on my mom's piece of stuff 8 year old imac is different
It has no IPv6, Only IPv4. And for who the forget knows why it makes you have to enter in your DNS server IPs.
So wait, to portforward I have to loving call my ISP?
I guess. That is really loving stupid.
Anyway, When I give up trying to set the other two computers static IPs, I try mine alone.
Doesn't loving work. I set it to something like 10.0.1.4 that would normally work and isn't being used by the other computers, and it breaks my loving internet connection. So I can't port forward being that I need to use the IPv4 address but it changes since it's a dynamic IP Address.
What the forget am I supposed to do if I can't set it to a static IP without being unable to connect to the internet?
Take in mind my router's I.P is 10.0.1.1.
It loving sucks because I can't set a static IP which means I don't have a single IP that I can set as my private IP address for port forwarding.
So what am I supposed to do that can fix whatever reason when I set my static IP my internet gets forgeted?
