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

When you say the last firmware upgrade, means which version?

[Valter_Veiga]

Hello,

After the last firmware upgrade (Krack) the system is stable.

The pings are not great, but are constant.

The previous were "Jumping" from 1ms to 1000ms
