I've done all the above and iPad still says it can't find an air printer ..

Is your printer AirPrint enabled?

1. Buy a AirPrint enabled printer; see list below

2. Run the CD provided and setup as network printer; this will setup your printer to the same network as your iPad

3. Start printing from your iPad without wire

Have you run the CD and set it for network printing?

What model router is it?

That router was first produced eight years ago, making it quite aged.

There is a firmware update available for it but even it is three years old: http://homesupport.cisco.com/en-us/support/routers/WRT110

In general, users have reported unreliable AirPrint operation with that router even with updated firmware. It may be time to retire it.

I recommend a genuine AirPort Base Station.

Also be sure to set your router to allow Multicasting, it is disabled by the default configuration of Linksys routers/

You may find the option within the router configuration under Security.. from there check the Filter Multicast option and save the changes..

For any further assistant I would suggest contacting your ISP, the router should more likely be compatible with AirPrint.

You might try turning off IPV6 on the printer. Just did an install for my mother-in-law and that's what it took.
