Problems connecting powerbook to ipod touch through wifi

Question

Hi,
I searched for previous posts but couldn't find a solutuion. I have been using the high speed internet from my powerbook to connect to my iPod Touch through wifi to be able to use the internet on my ipod close to my computer.
I have been using the advise of "mrtotes" on another apple discussion. I copied the URL and the part of the discussion that I use.

"Hello and Welcome to Apple Discussions,
OS X's IP firewall is probably blocking incoming Port 80 requests (i.e. web traffic).
Go to  menu > System Preferences... > Sharing > and under Services check "Web Sharing".
I assume you already have switched on Internet Sharing on the Internet section under Services on the Sharing pane and are "Sharing your connection from": "Built-in Ethernet". To computers using "Airport".
To secure the connection (recommended) go to  menu > System Preferences... > Sharing > Internet section. Click on "Airport Options..." and check "Enable encryption (using WEP)". Then enter a password twice. Users will need to enter this password to share your connection, although you should be aware even 128bit WEP isn't all that secure.

I have been using these instructions successfully to connect my ipod to my powerbook for several months but now it has stopped working. When I get to System preferences>sharing>interenet and I select "Share yur connection from: Built-in ethernet", the only opions I have for "To computers using:_______" are "Built-in Ethernet" and "buildt-in Firewire" nothing about airport. Also at the bottom of the sharing window the "Airport Options" is greyed out and I can't select it. So I went to system preferences>network and my airport is listed but "Airport is currently off" So I click "Connect..." and the "Internet connect" window opens to the "airport" tab. "Airport Power: Off" and everything is greyed out so I can't select anything. And at the bottom of the window. "Status: No Airport Hardware found". So I went to the system profiler clicked on "network" on the left hand side, then clicked on "Airport" at the top right under "active services" and then looked a the information on the lower right side of the window:
AirPort:
Type: AirPort
Hardware: AirPort
BSD Device Name: en1
IPv4:
Configuration Method: DHCP
IPv6:
Configuration Method: Automatic
Proxies:
Proxy Configuration Method: Manual
ExcludeSimpleHostnames: 0
FTP Passive Mode: Yes
Auto Discovery Enabled: No
Strangely, If instead of clicking on "Network" on the left side, I open up the drop down list under "network" (i.e. Airport card, firewiall, locations, modems, volumes) and click on "airport Card", I'm told "no information found"
Any solutions?
