2.4Ghz Latency goes high suddenly

thiago_alves_96 — Mon, 28 Oct 2019 17:56:43 GMT

Hi all,
I have an total ruckus environment ( ZD100 + Ruckus 610 APs) into 2 of my offices.
On both offices, i have a problem on the 2.4ghz frequency where its latency goes high ( around 300ms on ruckus dashboard ) and people begin to complain about slow connections.

It only solves when we reboot the AP that haves the high latency.

How can i solve that?
I have around 65 aps on one office and 10 in the other one, all of them are configured following the ruckus manual for high density environments.

My firmware is 5.1.0.0.496

Thanks in advance

I had a similar sounding problem, the problem was the 1000 a second broadcast rate. Limiting broadcasts on our switches helped some, but I then disabled multicast broadcast on the SSID with most of the users, and that solved it instantly. It somewhat broke mDNS bonjour printing... but that's not such a big problem.

we have around 50 AP's, all R600's with vSZ 5.1 1000 devices, mostly Apple.

How did u make that work? I just segmented my networks between 5 and 2.4 ghz to make it work smoothly at least on 5ghz.

Thiago, latência pode ser n fatores, principalmente a distância entre o STA e o ap. São 65 antenas, como funciona o seu ambiente? É um ambiente de propagação livre (aberto), possui andares? Todos os 11 canais estão habilitados ou só estas usando o 1, 6, e 11? Está utilizando o background scanninng, óu o Channel fly? Qual é a sua canalização pra 2.4GHz, precisamos de mais informações para pode ter ajudar.

Oi Jardel, tudo bem? Meu ambiente é um prédio de 6 andares, com os APS espalhados entre eles, divididos por andar. Só estão habilitados o 1,6 e 11 utilizando Background Scanning. A canalização que utilizo no 2.4 é 20.

Did u changed the Directed MC/BC Threshold to 0?
