Check the Radius server logs and check if the secret is correct.

i checked in meraki radius authenticated test, its show all AP passed for authentication test, as our customer is using NPS, i think i need to check in NPS log

Filter the security event log on the NPS server for events with the IDs 6272 and 6273.  6272=success, and 6273 =failure.

Look at what it says it denied access.

[Keith_Li]

may i ask below is related with NPS server also ?

checked that the problem machine wireless lan is using 802.11ax, so the 802.11w should be supported on the machine, just wonder why i still receving the auth failure ?
