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.
