If you are looking to fix specific bugs, let me know with your current setup or your exact OLT brand (e.g., Huawei, VSOL, Syrotech) so I can guide you on configuration compatibility. Share public link

Turn over your router and look at the physical sticker. Note down the exact model variant (e.g., F670L v9.0 or v6.0). Log into your router’s gateway dashboard (typically 192.168.1.1 or 192.168.0.1 ) and check the tab. Match your current Boot Version and Software Version string. 2. Backup Your Current Configuration

Once completed, the router will reboot automatically. Log back into the interface and check the page to confirm the software version has updated. It is highly recommended to perform a factory reset after major firmware structural changes to clear out conflicting cache entries in the NVRAM.
