HG8310M XPON Terminal (ONU/ONT). This is typically used for FTTH (Fiber) internet connections.
My thoughts on this:
Pros: Reliable enough for standard home internet (50–100 Mbps, sometimes more).
Limitations: This is an older model. Wi-Fi coverage and speed will not match newer dual-band (2.4GHz + 5GHz) routers.
Default login info is visible on the sticker: IP: 192.168.100.1, Username: root, Password: admin. However, many ISPs change these.
