Thanks you
This is in home wireless, single AP. No roaming
We are using 20MHz for 2.4g.
Why only 3 2.4ghz bands? The spectrum in this area is very crowded, surely all 11 channels is better?
We have some multi unit homes with 4-6 of of our customers alone, never mind our competitors.
We’re also planning to server 100+ unit affordable housing when we have a solid foundation.
I know of one 2.4G device that just won’t connect, even right on top of the AP. Was leaning toward the frequency being at fault.
I do think the AP may be a bit to powerful..
What is a good figure? I went with the regulatory max. 27dbi or even lower?
Doing some live debugging shortly with a user have chrome cast issues where the didn’t previously. It seems the signal is better but the throughput is worse.
I’ll adjust my post with my findings.
Sigh of course the problem isn’t there when I connect 
CCQ looks a bit better with 27dbi.
Wish I could set it dynamic but (and this is easily repeatable) one poor device cripples the network for all.
Just grab an Iphone5, go to a 3 bar spot, do a speed test(iperf3) with a decent device (Samsung S5 Active in our testing) and see good numbers. Run it on the Iphone and see terrible results, run again on the S5 and see terrible results. That will hold until the interface is downed and upped, then when the iphone reconnects it is crap again.
Statically set it and the problem disappears. But you’ve adversely affected all the customers that don’t have a crappy device dragging down the network.
Then there is Mikrotik’s totally screwed up channel bonding. Simply get enough customers and you’ll start hearing about disappearing networks and networks that exist but can’t be connected to.
investigate and you’ll see it chose an odd ball frequency, or it put the control channel outside the usable spectrum. Give it a correct connection list and that problem goes away.
2G didn’t have this problem, as it’s not channel bonding but it has a bad habit of choosing the first channel even when unusably congested.
Give it a list and it behaves correctly, but now I’ve got 2G connection issues.
This whackamole is driving me nuts. We are very close to abandoning Mikrotik inside the home. SXT’s are great, but we control both sides of the connection, it’s not 1000 random devices
