Re: Captive portal not showing in iOS 11 Beta 4 iPad

Hi Colin,

 

We are now testing with iOS 11 full release and find the internal Wi-Fi guest connection does not work with iPads, but OK with iPhones.  We don't know if there may be a glitch with network assistant within iOS 11 or somewhere else.  Every once in a great while, the iPad with iOS 11 can connect with internal guest Wi-Fi.

 

Thanks

Tony

Indeed and our IT is looking into fix it however any device on an older iOS versio can still connect succesfully. Any device on iOS 11 cannot.

Please see here:

It won't let you connect to a certificate that is expired, and "

Certificates signed with SHA-1 and/or using private keys under 2048-bits will no longer be trusted on High Sierra, iOS 11, watchOS 4, or tvOS 11."
 
I am not sure what the default certificates and the private key size is by default for your version of ArubaOS on the internal captive portal, but if it does not satisfy the statement above, that might explain it.

It seems like the default certificate in ArubaOS uses sha-1, so the answer is to generate a certificate with a 2048 bit length with sha-2 encryption for this to work.

 

Let me just say that the Aruba internal captive portal was not meant to be used outside of the lab, and the user should replace it with something that fits the security profile of the deployment in production.

Summarizing the solution to this problem is not uploading the devices to IOS 11?
