@d0ugmac1 thanks a lot it was cable connection. basically cable is short so I connected another cable extension using coupler and such it wasn't working. I checked then cable and it's good cable. so...

I have got EAP225 got all connected but green light keeps flashing every 5 sec. I have reset many times. I can not connect to to-link 2.4G OR 5ghz wifi SSID
