Latency problem difference between Mikrotik / Ubiquiti CPEs

RouterOS Wireless Networking
1

Hi there,

I’m using an RB912UAG-5HPnD (RouterOS 6.18) as WISP AP with 50 stations. CPE are both Mikrotik and Ubiquiti.
Here is my problem (noticed also with a RBMetal5SHPN on the same site): very often at all frequencies latency is very high but only on Ubiquiti CPEs I’ve got packet loss.
What could be the cause?

Here is my wlan config:

/interface wireless
set [ find default-name=wlan1 ] country=italy default-forwarding=no disabled=no frequency=5580 ht-rxchains=0,1 ht-txchains=0,1 hw-retries=15 \
    l2mtu=2290 mac-address=D4:CA:6D:77:DF:E8 mode=ap-bridge radio-name=Gaeta4 rate-set=configured security-profile=secprofile ssid=myssid \
    supported-rates-a/g=6Mbps,9Mbps,12Mbps,18Mbps,24Mbps

/interface wireless security-profiles
set [ find default=yes ] supplicant-identity=MikroTik
add authentication-types=wpa2-psk eap-methods="" group-ciphers=tkip,aes-ccm group-key-update=1h mode=dynamic-keys name=secprofile \
    supplicant-identity="" unicast-ciphers=tkip,aes-ccm

Prima di tutto, non usi il tkip
Secondo, se lei usa l’802.11 questi problemi sono la normalità.
Terzo, se mette l’hw-retries a 15 invece che 7, con 50 clienti risentirà latenza.
Adesso si trova in una situazione ibrida dove è costretto ad utilizzare l’802.11 o peggio l’any per compatibilità.

Butti via quei giocattoli e usi solo mikrotik con nstreme o l’nv2.

Ciao e grazie per la risposta.

Nel security profile c’è il tikip, su wireless protocol ho “any”
Come è possibile che spesso (in meno di 30 minuti) la latenza sale su quasi tutte le frequenze?
Come posso indagare?

SE LEVI IL TKIP E’ MEGLIO…

“any” = accept any type of connections: 802.11, nstreme, nv2
if you have omitted NV2 security, anyone can enter on your network with any 5ghz RouterOS device…
the ubiquity are forced to use 802.11 because do not support nv2 or nstreme, the worst protocol.
the mikrotik CPE can use any of 3, but if you omit on cpe to specify protocol, can use nstreme or nv2.
Mixing all the protocol on the AP, cause only latency, problem and really big mess…
