I am by no means a pro but...
Okay, I assume you have found out how to access your router configurations? Usually you simply strike the router's address in your web browser (router's IP) and get in to change settings.
Well, some routers require wired connection in order to do that.
I also assume you have found out how to make connection between your router and outer world to work. So basically what you need to do, is to set up passwords and so on.
One option is to use WPA/PSK as authentication method, and TKIP as encryption type. That's not the safest possible method, but much better than open connection *shrugs*
You should be able to find those words from your router config panel. Then set the password you wish to use.
Save the settings, and go to your computer's control panel. (I assume you have XP **SHRUGS**)
Select network connections, and 'create new' Or just edit your current wireless connection by right clicking it and selecting properties. Then select wireless networks tab from the properties window. (Yes. Up there) Select WPA/PSK from upper drop down menu, and TKIP from lower one. Write the same password into lines below, as you wrote on router. Go to last tab on that box (up there again) and check the automatic connection box.Hit Ok untill last damn wirudows box is closed. Cross your fingers and say your prayers. Close your browser. Unplug the network cable which may now be plugged between router and your computer. At the bottom right corner you should see the icon of the connection. right click it, and select 'fix connection'. Wait untill stupid lil windowsish boxes stop flashing on screen. Open browser and type curlysworldoffreeware.com at the address bar. Hit enetr. Pray a lil more...
That's all I can suggest
And finally, I try to start updating the site tonight. I still can't promise a thing, but I'll try

Take care, and say Hi Deeeeeee Ho and congratulations to Tanja and the lil princess
