Hi,

I have cluster of 5 IAP 205's. I have two SSID's, one with 2.4 and 5Ghz and one IoT 2.4Ghz only. I notice that some devices on the IoT SSID are having stability issues. I think I have set all as optimum as possible, but I would appreciate it if  someone can review my config.

What is the reported channel utilization on the 2.4GHz?
What are the by ARM selected channels and power for the APs?
Do you have broadcast filtering enabled?
You may try to enable 11d/h, some devices work better with that.
Is it just the ringcam that's giving issues?
What firmware version do you run? Have you upgraded to the latest already?
What is the distance between the device and the AP? You may try to increase the 2.4GHz power to see if that makes the connection better. 57 Mbps link speed can be quite low, depending on the device specifications. Your shelly's report 72 Mbps which seems like the maximum they support.

We have multiple RingStickupCam, and those seem to be the most problematic. The 6d one has fairly good signal and speed but we cant have a stable ping to the device.

Ping to RingStickupCam-6d

Are there any issues with my config? Is there anything else what could be cause this instability?

Help is much appriciated! Regards,
Bastiaan

Hi Herman,

Here are the anwsers to your questions:
1) They are farely high: 69, 68, 66, 25 and 19% while 5Ghz is around 1%.
2) They are ARM assigned, so not fixed.
3) Yes, ARP only.
4) Ok, will test with this and report back later.
5) Well, all 2.4 have overage problems but the ringscam's are the most affected. But they are ussaly around the border of coverage.
6) Running the latest, 6.5.4.24 but had this problems at previous versions.
7) I have experimented with higher power gains, the signal and speed increased but the packets drops stayed the same. It did not help.

Thanks!

With 60-70% of channel busy, you can expect all kinds of issues. Getting the speeds up may help (higher power, better clients) as then it will take less time to transmit. You should find out where that channel busy is coming from. Are these high numbers on the same channel?

Can you bring the ringcameras closer to the AP? Or the AP closer to the ringcams? Clients that are on the coverage border, especially if these are pushing a lot of (like video) data, can be expected to be problematic for the full network performance. Or can the camera's run on 5GHz?

The high utilization is only on channel 6, when I change the AP to a other channel the utilization drops. What could cause this high channel utilization on channel 6, is this due to high interferrenace in this frequency range?

We did bring a AP in meters distance of the camera's, it did improve but still we had occasional packet drops which we dont see with other 2.4Ghz devices.

Unfortunately this Ring camera model can only talk 2.4Ghz.

I have enabled 11d/h and this seem to improve the stability. I think the high utilization on channel 6 could be a root cause of this issue do you perhaps have some quidance in troubleshooting this?

Quality/performance on 2.4GHz is quite poor in most cases, that is why 5GHz is preferred. Channel utilization can be WiFi-rx, WiFi-tx or non-wifi (intereference). The command 'show ap arm rf-summary' will give you a table of those parameters for all channels.

Then at least you can see which category the channel utilization comes from. It could be that you have another interferer in 2.4GHz.

With the default settings, ARM/Radio Auto, the AP should determine the optimal channel automatically, but if you have heavy users, it may be hard on 2.4GHz as there are only 3x 20MHz channels to pick from.
