Those two APs: 230 & 250 have the same OS version 10.3r.3 and the same network policy.
As new Macbooks are coming in, I see that under AP230 those new devices have a problem connecting. If I replace AP230 with 250 /the same firmware & policy/ that problem goes away.
The CRC rates are good as well as ACSP.
I have VM Extreme Cloud IQ build version: 18.104.22.168-IQVA
Do you know what else can be done to get those AP230s work with new devices ?
