Tristan, I do not have a laptop with the issue yet, I will ask our Desktop groups to report issues back. However, do you have Global IPv6 Config Enabled or Disabled?

Looks like this is a thing.... Has anyone chased this up with wireless vendors (assuming this has only been observed on a Cisco network) to work out whether it's a Broadcom or Cisco issue? I don't have one of these devices myself to reproduce the issue in testing which will make TAC case troubleshooting and diagnosis very challenging to provide. I've had a report of success from a student who has downgraded their release to 6.30.59.15 (previously 6.30.223.102). Ideally a root cause analysis will require packet captures to find out what's going on in wireless client land and what's different about the packets between devices that work and devices that don't. Has anybody progressed to that stage?

Very frustrating as it worked with a Mi-Fi I had handy. If I recall, someone else said that it was sending the DHCP request and the server was receiving it, but the client wasn't receiving the reply for some reason.

This seems to be limited to Broadcom devices running either Windows 8.1 or Ubuntu Linux (seen this on 12.04). Our infrastructure is Cisco based (derivative of 7.2.111.3 firmware) on 3600 series APs. Has anybody else seen something similar?
