I have two WAP150 and two WAP125 which are monitored by Zabbix.
One 150 reboots periodically under Zabbix.
Today I investigate and find out two consecutive SNMP request cause rebooting.
Below is my test code which raise rebooting both 125 and 150.
// UDPsend.cpp #pragma comment(lib, "wsock32.lib") #include <winsock2.h> int main() { const char data3[] = { 0x30, 0x2b, 0x02, 0x01, 0x01, 0x04, 0x06, 0x70, 0x75, 0x62, 0x6c, 0x69, 0x63, 0xa0, 0x1e, 0x02, 0x04, 0x2d, 0x82, 0x4e, 0xe9, 0x02, 0x01, 0x00, 0x02, 0x01, 0x00, 0x30, 0x10, 0x30, 0x0e, 0x06, 0x0a, 0x2b, 0x06, 0x01, 0x02, 0x01, 0x02, 0x02, 0x01, 0x08, 0x09, 0x05, 0x00 }; const char data4[] = { 0x30, 0x2a, 0x02, 0x01, 0x01, 0x04, 0x06, 0x70, 0x75, 0x62, 0x6c, 0x69, 0x63, 0xa5, 0x1d, 0x02, 0x04, 0x2d, 0x82, 0x4e, 0xea, 0x02, 0x01, 0x00, 0x02, 0x01, 0x75, 0x30, 0x0f, 0x30, 0x0d, 0x06, 0x09, 0x2b, 0x06, 0x01, 0x02, 0x01, 0x02, 0x02, 0x01, 0x08, 0x05, 0x00 }; WSAData wsaData; SOCKET sock; struct sockaddr_in addr; WSAStartup(MAKEWORD(2, 0), &wsaData); sock = socket(AF_INET, SOCK_DGRAM, 0); addr.sin_family = AF_INET; addr.sin_port = htons(161); addr.sin_addr.S_un.S_addr = inet_addr("192.168.8.8"); // WAP address sendto(sock, data3, sizeof(data3), 0, (struct sockaddr*)&addr, sizeof(addr)); sendto(sock, data4, sizeof(data4), 0, (struct sockaddr*)&addr, sizeof(addr)); closesocket(sock); WSACleanup(); return 0; }
I will wait for firmware update.
Thank you.

1) Check device logs when this happens , 2) Use a syslog server and also configure an snmp-trap receiver, use both platforms to check for last-gasp information when the device reboots 3) As you say -> use latest firmware.

Thank you Marce.
WAP150 : FW version 1.1.2.4
WAP125 : FW version 1.0.3.1
There was no log events at reboot.
The log is very similar to cutting off power and on.
My syslog server records following:
