You'll need to assign the controller an IP address and subnet gateway, easiest to use your network IP +10 on the end or so - I can walk you through that, easy. IP should look something like 192.168.0.99 - the gateway stays the same, something like 255.255.255.0.
Then from your pc, enter in that IP in your browser. If you can see it, cool. If not, the IP is not setup properly.
If you are setting up a wireless access point, it will need to be configured in a similar manner. You'll also need to setup some port forwarding on your main wireless router so when you try to access it from the outside world, you can get all the way to your controller.
Either way, once you get it all running you can access it from inside your house. Unless you have a static IP, you'll need to setup a free dynamic DNS service to so you can access the controller from the web outside your house. (most ISP's do not give static IPs unless you pay extra, this means the IPs the ISP's give you for internet change) Think of it like the phone company giving you phone service but randomly changing your number all the time.
A dynamic DNS service runs a little app on your home computer to update your IP address. So to see your controller you will type in pandamaniac.dnsalias.com or whatever you choose. just google dynamic dns.
This was my experience, there may be other ways to do it but it's pretty cool seeing my controller from my BB Bold and getting email alerts to the alarms I set.
Hope this helps.
