We have been running SonicWALL VAPs for years with EAP against Windows Server NPS. This week, for no apparent reason, wireless clients are no longer able to connect. The NPS server sees the authentication request from the SonicWALL, grants access, and packet captures show successful communication in both directions. There have been no changes. Started to suspect a Windows Update, or some mitigation pushed for the KRACK vulnerability, but the problem also affects Android & iOS devices. WPA2-PSK wireless networks are fine. We feel that we can't be the only customer suddenly experiencing this issue. Can anyone relate or provide thoughts? Thanks in advance!
