Wireless gateway authentication

I am seeing a similar behavior. Prior to 3.0 the device would establish the wifi automatically and then I'd open up safari, go to the gateway web page and authenticate.

Now, post 3.0 I am unable to even get attached to the wifi. When I try to connect to the wifi the configuration sequence. obtains a dhcp lease and gets me to the gateway web page at which point I tap the link to authenticate. I get the message "Authentication Challenge Hotspot cannot handle this page because the server has issued an HTTP authentication challenge" I then tap 'OK' and it does nothing. It would be refreshing if it would allow me to answer the challenge it cannot handle. Terminating the sequne at any point also drops me from the wifi. I'm a bit surprised it is failing to allow user intervention at that point. Bottom line is the device is not presently capable of using the wifi here at work.

I'm having the same issue.. When I choose the network, it brings up a screen that's trying to go to apple.com and it says log in.. However I don't get any input boxes.

It was working right before 3.0, so it is related to the update.

I can connect at home, I just have no idea what to change at work to make this work, and there's not that many information on this, since it's a one day old issue...

A good amount of people are having this issue, since there´s no fix apparently as of yet, please report it to Apple here:

I am using an iPod touch but thought I'd reply here as I first saw this issue reported here. As of today it seems to be working. Running OS version 3.0 (7A341) I don't recall any updates being applied to the device so I am unsure what has changed. I was using 1Password and the a pop up box titled "Select a Wi-Fi network" appeared. I had simply dismissed it several times before finally letting it try to do its thing. To my surprise, it connected fine to the Wi-Fi. I was then able to open Safari and enter my credentials in the http gateway. Now it seems to be functioning as intended and I am able to connect everytime without having to re-enter my credentials.

same problem here. using proxy authentication gets stuck at the log in screen. the only option is to cancel.

I've only just noticed this thread after starting a new topic on this problem earlier. I'm seeing a similar thing on a network I installed a while back based on ZeroShell. This presents a Captive Portal for log in and I'm getting the same symptoms of none of the buttons doing anything.

One solution I have come up with (and it's a really ugly hack!) is to return a DNS failure when the iPhone looks up www.apple.com

The box that runs the Captive Portal is also the DNS server for the network, so I created an authoritative DNS record for apple.com and left it devoid of any 'A' records.

Now when the iPhone does a DNS lookup on www.apple.com it gets the DNS failure and doesn't show the 'slide' screen with the login and password, nor does the iPhone lose its assigned IP address when exiting the WiFi connection app. The user can then go into Safari as normal and enter the login credentials there.

This does of course mean the clients can't get to any apple.com pages, but it's better than not being able to get to any at all!
