I have a weird and inconsistent problem with my iPad: self-assigned IP addresses at public WiFi access points.

I have both a 3rd Gen iPad and an iPhone 4. The iPhone never gets a self-assigned IP address. The iPad does, but only now and then.

At one coffee shop that I frequent it would get a self-assigned IP address every time I visited. This lasted three or four weeks and then fixed itself.

The iPad always gets a self-assigned IP address at the EVA Lounge at LAX, but not at any other EVA Lounge. Other iPad users seem to be able to connect with no problem. My iPhone connects there with no problem.

Today the iPad got a self-assigned IP address at a different coffee shop. The iPhone connected normally. When I moved on to a restaurant for lunch, both the iPhone and iPad connected normally.

The iPad never gets a self-assigned IP address at home where the router is an Airport Extreme.

Here's what I've tried to fix this problem:

- Renew the lease

- Forget the network

- Reset the iPad

- Reset network settings

None of these solutions work.

Any ideas?

I've seen where people can connect easily with an WiFi AP while others cannot, using the same model device. Frustrating. I've experienced issues with my mobile when it encounters a WiFi AP set to WPA/WPA2 AES + TKIP as this seems to really confuse it.

You could try doing a "Recovery" through iTunes that will wipe and reinstall IOS on the device. Otherwise if the iPad is still under warranty, take it to an Authorized Apple Service Center and have them replace it.

a quick search of google: "iPad gets self-assigned IP address" gives tons of results from unhappy apple users with no clear resolution.

Right. Lots of people with similar problems and no sure-fire solution.

I guess a wipe-and-restore is the obvious next step.

Thanks.
