Hi,

I have another question. This one has been driving me crazy for quite some time now and has been a noticeable issue since deploying Merlin - but I think probably has been a problem before, but I just wasn't paying attention to it yet. I've found various threads on the matter both here as well as on Reddit (most recent I think is this one: https://www.snbforums.com/threads/a...ess-clients-dropping.88646/page-2#post-924146) and you have tons and tons of suggestions. "The problem is beamforming!", "The problem is your iPhone!", "You need to select channel 36!" and none of it actually helped. So I figured I could find out what device may be the culprit, but upon closer inspection I see it doing this over and over again with multiple devices:

I found that rather interesting, as it disassociates with nearly half of the connected devices at once at exactly the same time; only a few of which are Apple. (In case it truly is the iPhone, but I don't have "private Mac" enabled to begin with, because I give static DHCP leases based on MAC-address - been doing so for years).

This begs the question: when it does the ReAssoc, it displays the RSSI. The -82 one for example certainly would be disconnected by it and -75 is on the border. (The -58 absolutely not).
... Is this problem simply caused by the Roaming Assistant? Or am I being too optimistic in hoping that nobody suffering from this issue in the countless of threads on it has thought of that? :p
I'd prefer to keep the Roaming Assistant on to give devices a little nudge out of the door when reception is on the border of the two AP's.


Thanks :)
