Now that you've said that, when we initially hung that AP I left the power supply at the office. Thinking back I think I may have had another 1g POE with me but it just may have a CPE POE on it.
Something for me to go look at after Louisville. Thanks!

The APs need to use the 1G power supplies or you'll have issues. You cannot use the CPE's power supplies. The RF link tests will be great but the tests that run through the ethernet port will not work well. See the attached graph, you can definitely see when we changed out the PS in this graph of usage. What's weird is this AP was powered from a CMM Micro. We re-cabled it to run directly into a cambium power supply. Done this on about 5 APs at different sites and it's fixed it every time. The other thing to keep in mind with the RB2011 is what port things are plugged into. Ports 6-10 only have a 100M aggregate link to ports 1-5. If the aggregate of ports 6-10 require more than 100M, you'll have issues there too. Joe Falaschi e-vergent On Mar 11, 2016, at 11:56 AM, Robert Haas wrote: I have not yet. This happened right when we acquired another network so I haven't had much time to spend diagnosing the issue. I did open a trouble ticket with Cambium but it was closed due to inactivity. -----Original Message----- From: Af [mailto:af-boun...@afmug.com] On Behalf Of Nate Burke Sent: Friday, March 11, 2016 11:33 AM To: af@afmug.com <mailto:af@afmug.com> Subject: Re: [AFMUG] Poor throughput on ePMP AP Have you tried a router other than the 2011? I have 1 site where I have a 2011, and It might be having this problem, but haven't done much testing from the CPE side. Other sites with CRS or 1100's seem to be fine.

Another factor was to make sure that all backhauls in the path were running at full connection speed (in other words, a backhaul whose Ethernet port can run at 1000M should be running at 1000M, even if the traffic never approaches 100M) all the way out to the internet. -- Darren -----Original Message----- From: Af [mailto:af-boun...@afmug.com] On Behalf Of Justin Wilson Sent: Sunday, March 06, 2016 10:27 AM To: af@afmug.com <mailto:af@afmug.com> Subject: [AFMUG] Poor throughput on ePMP AP Sp I have an issue. Tower is a 4 sector ePMP setup and two backhauls. We are seeing poor throughput when connected to the APs (all of them). Signals are great. Quality and capacity are great. When going through the AP we are consistently seeing 4-5 megs of download out to a known speedtest server. If we plug into the same wired port on which the AP, which gave us the poor throughput, we can max out the 100 meg uplink. Issue only happens when going through the wireless. Here is what I know: 1.APs are set to 75/25. SM can do a link test and get 50meg x 12meg on the link test. So RF is good. Isolated AP to where only one client was on. Same great results. 2.Firmware does not seem to be a factor. Can reproduce this on 2.6.1, 2.5.1, and 2.4.3. 3.Have replaced POE injectors 3 times with different manufactures. 4.Does not matter if it is DHCP or PPPoE. Hard wired is fine. Wireless stinks. The AP is plugged into a POE which then plugs into a Mikrotik 2011. If I plug into the same exact port the aps plug into speeds are great. The only thing that is left is patch cable to POE, Cable to AP, or AP. I refuse to think 6 cables on the tower do the exact same thing. The odds for that are Powerball winning crazy. Speediest from a laptop hooked to an SM to the 2011 are poor. 4-5 megs consistent with spikes up to 10-13, but all over the place. Acts like negotiation. Have set Mikrotik to Auto, to 100 meg full, only accepted 100 meg on auto. Customers who have 5 meg packages or below don't see this. Those with 10 meg packages are the ones seeing 4-5 meg speeds. 10 meg packages did work. Clients are mainly at 2.6.1, but we can reproduce this with a 2.5 and 2.4.x SMs. Nothign has changed in the network, which tests out just fine up to the point it gets handed off to the ePMP. Anyone ran into this? Any thoughts? Justin
