NAND ECC BCH-4, page size 0x800 bytes, spare size used 64 bytes Having the option to reconfigure one of the LAN ports as a WAN port.I just want to disable DHCP and setup WiFi to my choosing, and plug it in via ethernet cable to the LAN in an office network. In other words, if the fiber optic port, phone ports, and USB ports don't work, that's ok for now. Intended use: The most immediate use is as a wired and wireless switch. Notes: I have logged into the admin interface, using the default credentials printed on the device, and the admin interface is extremely basic - for example, no option to disable DHCP nor an option to upgrade firmware. Here are some photos, and I hope that based on these photos folks here can help me figure this out. I understand this requires both a way to flash it, and an understanding of what firmware to flash it with. I have a FiberHome AN5506-04-FAT GPON ONU that an ISP abandoned, and I want to know if I can put OpenWrt on it.
