HI
WHAT IS A GOOD SINGAL TO NOISE READING, AND TX/RX CCQ.
I AM HAVING LARGE PINGS AND LOW BANDWIDTH AT DIFFERENT TIMES, THIS CAN LAST FROM MINUTES TO HOURS AND THAN STAY WORKING FINE FOR ONE OR TWO DAYS WITHOUT ANY TROUBLE.
PLEASE HELP
THANK YOU
We typically aim for a SNR of 25 or better, a CCQ (fluctuations accounted for) of not less than 70%, and a radio signal strength of -79 or lower. Any worse than this we consider a stronger card, different antenna, elevated mount, etc.
BTW, my installers have to be constantly reminded to create a clear fresnel zone. This is a VERY common oversight. Read more here:

THANKS FOR ANSWERING
I HAVE THE S.N.R READIN NOT GRAETER THEN 25 IN 90% OF MY CLIENTS, I HAVE SEEN S.N.R READINGS FROM -3 TO 26.
I HAVE A CLIENT ABOUT 600 METERS WITH A PERFECT L.OS. AND SIGNAL BETWEEN 50S
AND STILL HAVE THE LOW PERFORMANCE AT THE SAME TIME THAT THE OTHERS HAVE.
ALL POINTS WORK FINE FOR HOURS AND THEN FOR MINUTES OR 1 OR 2 HOURS THE LONG PINGS AND LOW BANDWIDTH TIME APPEARS.
I HAVE RB133 AND UBOQUITY XR2 RADIO END A 16DB 120º SECTORIAL.
DO YOU HAVE ANY MORE IDEAS?
THANK YOU
sounds like noise (in-band), if it’s intermittent, and is across the board (all clients seeing high pings low throughput).
Try a different channel, or a channel filter.
I HAVE A HYPERLINK FIXED CHANNEL BANDPASS FILTER I ONLY USED A FEW HOURS BECAUSE SIGNALS DROPED VERY MUCH, ABOUT 20% I HAVE A ONE WATT AMP THAT I AM NOT USING. DO YOU THINK I SHOULD TRY IT WITH THE AMP OR SEE WHAT HAPPENS IF I HAVE LOW SIGNALS??
YHANK YOU
First off - please find your caps lock next to the A button and press it.
I have seen this kind of symptoms before. Sometimes switching to B-only mode will fix it. In one case, we had the same behavior and had to replace the XR2 with an R52H to solve the problem.
Do not - repeat - DO NOT - use the amplifier. NO.
A couple of weak links can slow down the AP for everyone else. What is you worst customer’s SNR?
Throw out the AMP…!!!
… and start again by re-configing - or at the very least checking EVERY config…
Amps should be forbidden ..!!
Just my .02c worth
