Apple MacBook Sierra Wireless WIFI 5GHZ

[Valter_Veiga]

MacBook running HighSierra in wireless 5Ghz very instable in access-points 3825, 3805, 3912 with controller C25 running v10.31.04 ou v10.31.04.

After a week of testes the best solution is: Disable 5Ghz and use the 2.4Ghz interface Only

Do you have ATPC turned on for the 5 ghz radio?

About 3 weeks ago, after I have upgraded to version V10, i started to recive complains about the wireless from 2 Mac users. The principal and a coordinator, two in about 600 devices.

I stated to test this 2 macbook pro and macbook air computers, with a simples test , Ping, to see if they were disconnected from the network. But what I see was big ping replays .... by mistake, I disable the 5Ghz Radio , WOOO I was suprisse with the ping replay in 2.4Ghz, it is wonderfull.

I run a lot of testes changing options, but the 5Ghz was always bad ping replays.

In the weekend I decide , disable 5Ghz to the all system. Monday morning I was on costumer site.

In the middle of the morning a run into the principal. He told me that the Wifi in that days was working perfect.

In this client, only two users complain about the wifi.

PS: If we don't have complains it doesn't meen that everything is right

I don't know why the times would be different, unless the mac is prioritizing things differently .

Maybe one of the other folks with a large mac deployment can run a similar ping test: Windows -> mac and then Mac -> windows. I can try it, but it might take me a day or 2 to get my hands on a macbook for testing.

I understand the ping times look bad, but am just wondering if they are related to the actual problem of being connected but no network access. With only 1 5ghz radio enabled, does this mac get into that state of connected but no network access?

Yes, i'm pinging the mac from a windows cliente connected to the network. I don't have access to the Macs. Why is the ping so diferente from 2,4Ghz to 5Ghz?

[Valter_Veiga]

I Have all radio 5 disable in the school, the only one that is Up is that access-point.

I'm doing this test remotly, so the ping are done from a virtual server in the same VLan, the wireless console is run in a management VLan.
