Ubiquiti Nanostation general wireless signal strength questions

I have 2 Nanostation Loco M2 that are 400 feet apart.  Trying to understand things.

looking at the web admin pages for both devices, on the main page of the web admin, there's 'signal strength' which has all the colors (red -> blue) and it says -50dbm next to it.

Then there's a tool for antenna alignment

That has a signal level meter (currently both say -50db and are lit up to the blue line.  that page also has a 'max signal' slider.  when that is all the way to the right (full strength? it says -18db) the signal level meter drops  to just 1/2 of it lit but the -50 doesn't change (maybe to -49).  if you move max signal slider to 1/2 way, it says -54 dbm and the signal level is fully lit.

On the wireless page of the air OS, there's a slider for output power  max is 22dbm.  I am thinking I should dial down the power to not overload the receiver at the other end?  but how do you know the right settings / what's the max signal slider vs. output power slider?

The optimal signal strength is around -40dbm; but, it sounds like your interface is not giving you all of the info you need.
Of note are two other parameters; data transfer rate and signal to noise ratio.
Wifi automatically falls back to a slower transfer rate when the signal is not clear or strong enough to support the higher speed and the signal to noise ratio is an important factor.  When looking ate the SNR, lower numbers are better (i.e. -65dbm is way better than -50dbm)
If you can look at the other factors, do so and adjust the power accordingly.  If you can't, you'll have to do it by trial and error.

first, I am a moron.I was changing the signal strength slide on the wireless page and clicking 'change' button at the bottom.  didn't realize I had to click the apply button at the top to have it take effect.  Doh!

I am getting -50 for the signal strength at full power and dropped it down from 23 to 20 and signal went to -53.

Yeah, If they were 1' apart ,what would signal strength be?  -40?  at -50 to -53 the speed test was saying 75 up and 75 down (approximately).  so I guess that's 'good'?

yeah, lower = better (in some cases) , minus sign, etc. are confusing me a bit ; )

thanks!
