i have a ptmp system one end 532 with sr5 and a 10 dbi omni on the other end is a 532 with a sr2 and a 25dbi grid this link has been unstable ant best untill yesterday i hard coded the tx power mode to 26db and the link not only stablized but went to at the worst signal -86 what is the issue here both boxes are 2.9.27
What’s the distance of the link?
it is less than a mile and near line of site but there are trees in the way and that is the reson that the link was bad but what made this fix work
Yes world, there are trees in Arizona. 
In Northern AZ atleast…
Not like the scrub us desert rats get stuck with here in “The Valley Of the Sun”..

Maybe I can trade you some LA pines for some of that flat land! I am willing to part with all of them

Have you tryed 5 or 10mhz channels?
I have a friend that runs his whole network on 10mhz channels and he is doing really great with it.
no i have only used the standard 5 ghz
what does this do or change
i have tranzeo cpes if i make this change with they still be able to comunicate??
normally a channel in 5GHz environement uses 20MHz of the spectrum.
With this option you quarter or half the bandwidth of the channel u use to 5 or 10 MHz (you also reduce the max. speed to 27mbps or 13,5 mbps)
You have to check if your tranzeo cpes can do so, but I think most non-mikrotik stuff cannot do so…
default is just what the manufacturer has written in the EEPROM. it is mostly the best choice. setting more might overheat and damage the cards, but if it causes no problems for you …
some say that lowering the power increases link stability. so this all depends on many things
The two other wireless OS’s can also do it. But I don’t really care for them.
