hAP AC - phone does not detect smart device (vacuum cleaner)

RouterOS Wireless Networking
1

Hi,

my phone (I tried 2) and robot vacuum cleaner are on same wifi network from hAP AC.
I start pairing in app, phone transmits network information (SSID and key) to the vacuum cleaner because vacuum cleaner gets an ip address and I see it on the network.
But in second phase phone and vacuum cleaner must be paired and this will no longer happen.

I took both devices to a different wifi network and there it works without a problem.

Does anyone have any idea what this could cause?
Thanks a lot.

Turn off 5GHz network on Mikrotik temporarily while you set up vacuum.

Thanks for reply.

I know the vacuum cleaner can be used on 2.4GHz only so I used a 2.4GHz SSID.
Now i have tried to turn off 5GHz, but unfortunately it still doesn’t work.

Sad :frowning:

I have something similar with raspberry pis when having capsman configured on ac^2

Trying to understand the pairing process…

I start pairing in app, phone transmits network information (SSID and key) to the vacuum cleaner → you connected the phone to the wifi of the vacuum cleaner, and started the process to swap this connection with a connection via an AP

my phone (I tried 2) and robot vacuum cleaner are on same wifi network from hAP AC. → at least you hope they are

because vacuum cleaner gets an ip address and I see it on the network. → that’s your test if they are. What does the “registration” in the hAP ac say about their connection? And are the IP addresses of phone and vacuum cleaner in the same subnet?

Now the phone must find the vacuum cleaner. This is mostly done through broadcasts.And that is sometimes not so easy.
Just some hints for checking …

  • is there client/Station isolation?
  • is wifi originated broadcast limited for wifi? Flood protection?
  • what kind of protocol is used for this discovery?
  • is an IP scan used?
  • multicast helper (conversion to unicast) interventions?
  • ARP table?
    -“hosts” table on bridge? Are both devices in the hosts table? Learning mode of bridge port (must be) on “auto”?
  • bridge port “horizon” set ?
  • timeout due to STP/RSTP of bridge ?

As to what bpwl pointed out and what stands out to me. Lets have you enable FULL multicast on your 2.4Ghz interface settings. Lets test this. Also might help you do a configuration export
/export terse hide-sensitive file=XXXXX

for setting multicast FULL on your wireless interfaces(s) [have to set on both 2.4g and 5gh interface]

Set Multicast helper to FULL

Also is default Authenticate Forward? This enable your wifi devices to see one another.

Default settings in caps-man have local forwarding turned off and client to client forwarding turned off.

Gotsprings is right, client to client is turned off. Multicast is probably not related.
