ZTE ZXHN H108N

ZTE ZXHN H108N is ADSL/ADSL2+ Wi-Fi router based on Broadcom 6328.

DSL will not work at all on devices with BCM63xx DSL chipset (due to unavailability of FLOSS driver for Broadcom chips). Consider this when chosing a device to buy, or when deciding to flash OpenWrt on your device because it is listed as supported.
See Broadcom DSL, Unsupported: DSL modem and Broadcom BCM63xx for details.

It seems that there are 2 different models identified as H108N, one based on Broadcom 6328 and the other on Realtek RTL8672. OpenWrt is only valid for the model based on Broadcom 6328. Instructions to know our chipset without opening the router:

telnet 192.168.1.1
