@YourInternetGuy Maybe it's just a problem with power supply fluctuations, suggest observing it continuously, here is a Beta new firmware you can give it a shot if you want.

@RonSenin It will work if you set the wired Network and SSID both, and keep the non-eap devices in the LAN. The portal will work on the wired network as well.

@u880 So strange, the SN is normally showing on my windows 5.13.22, maybe a reboot can fix it? I use Microsoft Edge to open it, you may try with different browsers.

@Tshukela Did you choose the Time zone? How did you set the NTP server? Take a look, try some TS: OC200 gets wrong System Time and Date via NTP Server

@Pietr-o What about setting the mDNS? Are the printer and the PC in the different interface? A detailed article here you can see.

@Fozzie I don't have issue on my EAP225 5.1.1 new firmware, are you sure this issue is caused by the new firmware? Have you connected to the router 2.4G and test the speed? Suggest testing the speed...
