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

Hello Umut,

At the moment, the best solution is to disable 5Ghz.

I will run a test with Sam "setup" and I Will give the feed back.

Hi Valter,

disable 11k ( on all VSN please which is on the AP- not only on the affected VNS) and fast-transition if enabled.

Did you look on the client driver site if you make any updates ?!

If nothing helps please open a case in GTAC

Regards
Umut

No, Management Frame Protection DIsable.

Just curious - is the Management Frame Protection is Enabled on WLAN ?

Jeremy, tested with similar settings... the same.

This is and Access-Point with only 1 Client.

When I disable the 5Ghz the client moves to 2.4Ghz.
