[FEATURE] Consider adding F601 as supportted device #107 - GitHub

If you switch fiber providers or your ISP upgrades their central office OLT (e.g., from Huawei to Nokia or ZTE OLTs), your F601 may require a specific firmware version to register properly (O5 state).

1 GPON optical interface (SC/APC or SC/UPC).

Try accessing alternative IPs like 192.168.0.1 or 192.168.1.251 .

Your ISP identifies your home connection using either a or a GPON Password/SN . If your firmware reset wipes this data, your ONT will display a flashing "PON" light and fail to authenticate with the central exchange. You must copy this code from your old firmware interface before updating and re-enter it post-flash. 2. Remote Management (TR-069)

Absolutely not. The F600 uses a different CPU (Conexant). The F660 is a 4-port gateway with Wi-Fi. Cross-flashing will brick all devices.

Open a web browser and type the default IP address: 192.168.1.1 (or 192.168.0.1 on some versions). Enter the administrator credentials.

Scan your network adapters or try alternative gateways such as 192.168.0.1 or 192.168.100.1 . Alternatively, perform a physical factory reset by holding the recessed Reset button on the side of the unit for 10 seconds. 3. LOS (Loss of Signal) Light is Blinking Red
