What's the mdns issues you are seeing with 7.5? -----Original Message----- From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:[email protected]] On Behalf Of Eric T.

We're running 7.5 and so far it's the most stable of any code I've run in ages. I've had problems with my 5508 rebooting spontaneously for a long time on several different code versions. I've been running for 28 days now which is longer than I've seen in a while. No major bugs that I'm aware of currently short of the new mDNS discovery by the APs, but I'm working with the engineers on that one.

Hi, We're running an engineering variant of 7.2.113.0 to resolve some issues we were having with AP stability. We're looking into 7.5 for 802.11ac support. Is anyone running 7.5 out there or should we wait?
