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

The first indicator of problems, pings .... In an Lab with and access-point 3825 with only this client. You see the diference between 2.4ghz and 5Ghz.

This is a school with one access-point per room, the iMAC is on the table and the access-point in the ceiling.

Hmm, I have seen that in areas where 5 Ghz signal is not strong. What are you getting for a RSS from the AP and the client perspective? What are your power levels? I have seen this also when the power level of the AP is at 24 dB or something. The client can hear it but can't talk back 100% of the time.
