Interference would be my first guess.  Usually a station disconnects when it
doesn't have the SNR to sustain association.

Interference, poor pigtail, something to cause the RF side of it to suffer.

Forgot all about the pigtails/connectors, those things cause weird power
problems some times.  Very irritating.

Try adaptive noise immunity to client mode, short preamble, hardware
retries to 10, and see if it helps.

I have a RB411 that continuously gets disconnected from the access unit
with the following message in the log. It happens every couple of
minutes.

 

disconnected, extensive data loss.

 

Has anyone seen this before and have any suggestions on how to fix it?

 

The signal strength is -64db and the client has an 18db gain yagi
antenna. The cell is running n-stream and configured for 802.11b.

Extensive data loss means that you have tried to resend wireless frames,
though the hw-retries, and its failed 3 times sequentially.   On top of
that you are already at the lowest data rate, therefore it disconnects
due to extensive data loss.

Thanks guys for all the suggestions. I applied them yesterday and it is
has to be interference of some sorts. It was good for a while and the
issue cropped up again.

Re: [WISPA] mikrotik issue.

2011-10-10 Thread Olufemi Adalemo 
Here are some common causes of failure for radio links that are seemingly
good but fail periodically


   1. If you're getting constant interference all through the day:
  - It may be another radio nearby or even your own transmission on an
  adjacent band
  - It could also be a power supply issue, on some mikrotik boards so if
  you're using 24v you may want to switch to a lower voltage (never
  experienced this but a lot of people have reported it)
  - Lastly it could be interference from a high power transmission on
  another band e.g. a radio station
   2. If it is a regular periodic failure (every few seconds) it may be a
   radar system
   3. If it is an irregular periodic problem then it may be an industrial
   microwave oven
   4. If this happens at the hottest or coldest time of day then it may be a
   connector issue
   5. If this happens when it is very windy then check your antenna mount or
   look for trees and other obstructions in the path of your link
   6. Now here's the craziest one I ever experienced - if your link crosses
   a harbour you may be getting wiped out by a passing ship, ditto for
   construction sites and cranes


This list is by no means exhaustive but will help to eliminate the most
common causes of periodic link failure
