R500 short-term disconnection from the network

Andriy — Fri, 17 Nov 2023 07:31:21 GMT

Hello.
There are three R500 points in the network. Connected to Mikrotik POE. There is a short-term dump of one of the points (2-4 packages). If you turn it off, this problem appears on the second point. If you disable the second point, the problem appears on the third point.

Hi @Andriy,

This seems related to the network but not the AP itself.

If you have a managed switch, check if there are errors observed on the physical interface. Also it is worth checking if any device is causing high broadcast or multicast traffic which can also cause this problem.

We manage four Offices. The entire network is built on R500 (3-12) and Mikrotic CRS328-24P. And only one had a similar problem. The only difference between the offices is that in this case 2.4 and 5 are separate, in the rest they are combined into one LED, and there are no problems there.

The problem was localized experimentally. If you disable 2.4. The problem disappears.

Hi Andriy,

Finding the root cause of such issues is not simple. I suggest you to open a support case and work with Support team to investigate the issue.

May I know how many SSIDs are being broadcast on these APs?

Two, one for 2.4 and the other for 5. If you deplete them, the problem does NOT go away.

The problem was found.
One of the connected clients (device) had a problem. Just turned it off and the problem went away.

The problem was narrowed down. Some device running 2.4 is causing problems. By turning off the power supply to the offices, the range of devices was narrowed down.

2.4 and 5

Hello, Andriy.

Can you make sure the R500s are in the latest version?

Hello @Andriy

If you can confirm other APs in the same area and the same configuration work perfectly on the 2.4 GHz and also the affected user has been tested in the 2.4 GHz band in other APs and the client works fine, then we could suspect there is damage in the 2.4 GHz radio. Please contact RUCKUS TAC for further assistance.
