i have a 450i AP and a 450i SM (sitting at 8x/8x modulation and link capacity says it can do 130mbs aggregate) in the field. when i set the bandwdith to 40 down / 4 up and run a speed test to my server, i only get 20/4...this AP has less than 15 subs, and all of them have decent link quality indexes...anyone have any clue?
after interrogating my network, i am not sure whether it is an AP or SM problem--it appears to be an AP problem. When i go to my home (where my QoS is set to 60 mb down / 10 mb up) and link capacity tests reveal the radio is capable of 90+ mbps, and go to my speedtest server on ookla (directly connected to the radio), and i run a speed test, i top out at 25 mbps down / 7 up. when i perform a link test with MIR, the tests ARE NOT the same as a "server speed test."
again, i am hardwired straight to the 450i SM, bypassing the router.
How many SMs are registered to this AP? What kind of bandwidth are they configured for?
What does the link test with bridging and MIR return. I know you said not the same, but better or worse. I'm going to assume it was better (what was expected). Is this the same SM you started the thread with? Is it different, but on the same AP? If the link test with MIR returns the correct results it will verify the RF link is ok. If none of the SMs on that AP can achieve the correct bandwidth through ethernet, make sure that the AP can do so. How many APs share the backhaul? How are they performing? Connect to the switch at the tower and run a speedtest to the server from there.
