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

WHAT!? I beg to differ! I have not had ANY issues with my MBP using High Sierra. Well, none that I would contribute directly to some defect. My entire environment is 3825 and 3935s.

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.

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

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.

Valter - unless something changed on the Wireless network configuration on the MBP, we would need to see the AP trace log report to further determine if this is an issue with our APs. Have you opened a Case with our Support Team?

RE: Apple MacBook Sierra Wireless WIFI 5GHZ

Valter_Veiga — Tue, 03 Oct 2017 18:52:00 GMT

Yes I have open a case 01381969. The case has all the information and files.

OK - I just took a brief look at the settings, and there are a few that should be changed. Sam owns the case, and he will be sending out an update shortly.

Thanks for finding that Jeremy. Since the date that this article was published, we have found that the 256 setting did not resolve the issues we were troubleshooting. We have been working on removing all references to this setting since. Also - this article was in response to specific Chromebook problems, and not intended for other client devices.
