Mike, I think you are still running juniper?
We ran into an issue awhile back where the juniper routers were dropping arp requests. This caused jittery performance as a client might have to re-arp a number of times before it finally got a reply. While it was waiting for the reply data transmission stopped. You can run the following to see if you are having the problem. show policer __default_arp_policer__ Give us a shout offline if you have any more questions about this Stephen Holland Network Engineer Northeastern University -----Original Message----- From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:[email protected]] On Behalf Of Hales, David Sent: Thursday, March 08, 2018 2:11 PM To: [email protected] Subject: Re: [WIRELESS-LAN] gaming on wireless Another good troubleshooting tool is to connect to the wired interface on the console with a Ethernet to wireless bridge to eliminate the wireless interface on the console without taking your wireless network out of the equation. With a longer patch cable you can also position the bridge to avoid walls or other obstacles to the nearest AP temporarily.

With those types of walls, across the hall might be on the fringe of service for 5 GHz.
