The chromecast connects to a TV, not an Ipad.

Does your IPAD or your computer show the Netgear88 as an available connection. If you are using windows 7 you should be able to look at your "network and sharing" page. Then click on "connect to a network" (2nd one down). When click on that another screen should open up showing which band your computer is connected to. It should also show the OTHER band as well. It will also show the signal strength for both the Netgear88 channel and the Netgear88 G channel. If that information is there and the signals are good then the problem is in your IPAD. You may need to check to see if it needs to be updated as well.

It may be the device you are trying to connect. shut down everything, unplug , remove batteries, plug in the ISP model, allow the self test, plug in the wireless device, allow it to self test, plug in, reboot the device, laptop, desktop, ipad, phone, whatever. You say you can connect using a Ethernet Cable? Just no connection wirelessly?

Extender means it extends the existing Wifi or network. So the iPad now connects fine to the extender, but the extender needs to connect to the existing network either via Wifi or cable. You need to open from the iPad the admin page of the extender and find the connection details there to your existing network.

Have you opened Internet Options, Connections tab, Lan settings, Check Auto Detect. OR release and renew your IP address : http://www.wikihow.com/Refresh-Your-IP-Address-on-a-Windows-Computer Is your wireless adapter enabled? Drivers up-to-date? in working order?

I think you should check the wireless settings of the router netgear router and the iPad .
Do you have any other wireless computer or device in the network?
Can you connect any other computer or device to the wireless network?

If your wireless network is secured then make sure that you have the correct network key.

How to connect iPad to Wireless network

What version of iOS is the iPad running? Try updating the iPad to the latest version of iOS (4.3.1) and see if the wireless situation is better.
To update the iOS, just plug the iPad into you computer and look in iTunes to see if an update is available for the iPad.

That is a good router.
Is your wireless device (iPad? laptop? notebook?) using a Wireless-N adapter?
If not, all you get is the much-slower "Wireless-G" speed.

Measure, measure, measure.

If you use an Ethernet cable to connect from your computer to your router, do you get a much-faster connection?

How far (and how many walls) between your router and your computer?
