Saw this on a Lenovo w/ Broadcom nic (Win 8.1) earlier this week that would grab a lease on our older Cisco 1242’s/1131’s but not the newer 2600’s.

The comment is that they can connect at home but cannot connect to anything enterprise level. Cannot comment on the Ubuntu portion.

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?
