When I test our MR-46 and MR-86 access points using the "Dashboard throughput" tool in the dashboard I am finding that I get results of about 250-275Mbps on a gigabit ethernet connection to a switch that is connected to the Internet at 10GB. Computers plugged into the same port on the switch will get the full GB of up and down speeds.  Interestingly if I change out the fiber transceivers on the switch to the internet from 10GB to 1GB the Access point will report throughput speeds well over 500Mbps.   I can't figure out if the tool is wrong somehow or if something else is going on. This is reproducible throughout our setup. Gig speeds when tested with a PC (to speedtest.net and Google Speed Test) but no better than 275Mbps with an AP using the built-in Dashboard Throughput test...  dropping the uplink transceivers to 1GB from 10GB will increase the Meraki test speeds, but doesn't seem to change anything as far as the PC speeds... I hope that makes sense.   We are running 10GBase-LRMs on a Cisco 2960-x, and 1GB to the Meraki APs via Cat6.   Thank you in advance for any ideas/tests you might have to offer. ... View more

We have networking rooms that contain both large and small UPS units. One of the larger rooms, which contains the largest of our UPS units (has both lead-acid and lithium-ion batteries) is showing some odd TVOC numbers on the MT14 sensor. We have had some of the lithium-ion batteries go into thermal runaway in the past and we are hoping that the MT14 sensor might catch some of these conditions with any of the gasses these two types of batteries emit or might emit. Does anybody know if these sensors would detect excess Hydrogen or any of the many toxic gasses a failing Lithium-Ion battery might emit?  If so, how would that present itself on the Meraki Sensor Dashboard?   Thank you in advance.   This is a typical graph we are seeing in the TVOC detection area.. sometimes it goes even deeper red. Just wondering if what we are seeing could possibly be related to battery off-gassing.     ... View more
