Suggestions for hAP ac2 configuration

Hi everyone
I want some suggestions what to change on my router.
I own a caffe shop and i have put a ac2 as wifi access point with 5g and 2.4g.
I want to know what I them maximum of clients that the ac2 can manage at once.
Generaly the router have 20 to 30 at the same time the max i have seen is around 70 client devided between 2 wlans.
The other problem that is have most trouble is, the router disconnect the internet access to the clients like a time out session for around 5 to 10sec.
Not only the wifi client even devices connected with ethernet the that is more noticeable because is the pc for the live music. I get a 300down/100up form the isp so i don’t think that is isp speed problem.

The router is at default configuration.
Is there something that i should do or change to be more adaptive for my porpoise. And to stop the random disconnection.

Hex S refresh router with two Access points, very few access points handle 70 clients very well.
If stuck on one AP, look at High density access point brands look at wifi6 as a minimum ubiquiti, RUKUS etc…

Could it be that the 10 second disconnect is happening because the hAP ac2 is restarting?
Connect to the admin interface and check under System->Resources what the “Uptime” is.
Is that many days, or is it just a short time ?

I know that is very difficult to handle 70 clients that
But the disconnections happens even when a few clients are connected

The wifi do not disconnect form the device i can acces the RouterOS during those seconds the speed goes to 0

Although the number of clients you are serving are not exactly optimal for a single ac2, your problems in this case don’t seem to come from wireless problems. The fact that wired clients also have access interruptions confirms this.

That you can access the management interface also suggests hat your router is not rebooting.

So basically your problem is more probably related to somehow losing your internet connection.

The next in troubleshooting should probably be:

  • confirm the basic parameters (free RAM, free disk space, uptime, basically everything in /system/resources) near preferably before/after the outages
  • how often do these outages occur? randomly? peiodically?
  • what is the length of the outages? (I ask because you probably notice an outage when e.g. music playback stops, but there may be buffered data that is still played before you notice)
  • what do the logs show immediately after a disconnection? after reconnection?

You can go to the “Tools->Graphing” menu, under “interface rules” add a new rule for “all”, allow address 0.0.0.0/0, but do NOT check store on disk.
Also under “resource rules” add a new entry like that (allow address 0.0.0.0/0, but do NOT check store on disk).

Now let it run for a while and after you experience the problem look in the Tools->Graphing menu under “Interface Graphs” and “Resource Graphs” to the resulting graphs (you can set the interval to a day, a week, etc) and see if there is some particular pattern that relates to your problem, e.g. a large increase in traffic, in memory use, or in CPU use.

Another suggestion is when you catch the issue live, connect to the router and try ping something like 8.8.8.8 from the router itself using either the ping command from terminal or in WinBox Tools - Ping. If pings time out, you just lost Internet access, likely not the router’s fault.

The fact that you have 300/100 from ISP doesn’t necessarily mean it’s reliable. The issue could be with the upstream device (modem etc).

You could even set up Netwatch to do a continuous ping and then check logs when you have the issue.

Hi i don’t think that is a isp or modem related problem because the live music or live radio that is used for music get interpret only when connected with me mikrotik
I have done all the suggestion the form the other replies and i im checking the progres

Is there anything that i can do in configuration to optimize as much as i can for my application or the default configuration are good enough ?

For the usual “WiFi access point with NAT router” function, the default configuration should be fine.

When there are weird inexplicable issues, I would do a netinstall just in case. By the way, what RouterOS version are you running? Every new release has a long list of bugs resolved.
