Is this the same problem some people are saying is a Trango buffer problem,
but somehow only happens with ePMP?

We have the same issue, just at one site. Air test shows 75x20, a speedtest
plugged into the radio shows 15x10. Plugged directly into the same port on
the router (RB2011uais-rm) maxes the backhaul link (Rocket M5 @ 20Mhz).
Tried different AP radio's, different firmwares, tried a switch between the
AP & Router, tried with the client radio in bridge & nat modes, tried with
PPPoE and with static IP's assigned.. Nothing has seemed to make a
difference at the site. We have 7 other deployments that we have not seen
this issue with that have very similar setups.

we have the same Problem with the epmp Stuff..only problems and bugs from
the beginning!

We had seen some issues with ePMP customers on high-speed plans getting
poor speedtest results - we found that changing the customer's router's
MTU from Auto to 1480 helped immensely. 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.

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
