Re: [Ubnt_users] AF5x packet loss

[Scott Piehn]

We had a similar issue with an AF24 link.  In adition to the packet loss, one 
end has a netonix on it that showed errors.  After replacing everything on the 
side with the netonix, we found replacing the POE (did not have netonix on that 
side) on the far side fixed the problem

Definitely through the wireless link?  Not including the Ethernet?

  What routing protocols are you using across those links?

Re: [Ubnt_users] Aggregate Download Capacity Real TCP on AirMax-MxRadios

[Scott Piehn]

This has been asked many times and rarely answered due to the factors 
involved.  So here is my answer based on our speed packaged

M9 - Don't Use

M2 - under 10 CPEs. we use 10 and 20 MHz channels.  Channel width doesn't 
effect # of CPEs due to possible future interference.  We assume 
interference will pop up.  Customers are less than 3 miles.  Usually use a 
KP Omni.  Speed packages don't exceed 5 Mb.  traffic don't see over 10

M5 - 10 MHz wide - under 20 CPEs.  prefer under 15.  Get complaints when an 
ap has over 15.  Usually sectors 90 degree.  CPEs up to 8 miles.  Moving 
standard down to 6 miles due to interference.  speed packages offered 10 
Mb/5 Mb/1.4Mb.  5 MB is most popular.  Traffic see 15 Mb with spikes to 20 
Mb
M5 - 20 MHz wide - we started adding 20 MHz sectors to our towers with to 
many CPEs or to Many 10 Mb packages.  we use DFS only on the 20 MHz as it is 
an overlay.  the 10 MHz are all in the 5.8 band.  Traffic see 20 Mb with 
spikes to 30 Mb

I have seen people throw-out numbers a lot higher on CPEs and Throughput.  I 
can't seem to get all our rates at 65/65 or 130/130.  I have a hard time say 
no to people with rates 38/38 or under 100 - Rates depend on 10 or 20 MHz.


Just starting  our AC migration.

Subject: [Ubnt_users] Aggregate Download Capacity Real TCP on 
AirMax-MxRadios

We're looking for the amount of user traffic these radios are able to
pass (where these radios are APs). (The number we're trying to learn is
the cumulative amount of data X number of users are able to concurrently
pull through the AP at one time.) What is the real TCP throughput on the
following:

Rocket M900

Rocket M2

Rocket M5

I hope this isn't too ambiguous nor that it leaves too many factors out
of the equation (channel width for example). Please assume all CPEs have
-65 or better so that the AP isn't struggling to resend packets to a CPE
with a poor connection.

Thank you for any help you can offer. I did search the knowledge base as
well as the forums and didn't see a good answer. (There were some good
posts on the AC and AF-Xx platforms, but not for the "legacy" M radios.)

Thanks again,
Sam
