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 choosing 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.

Devices with Broadcom WiFi chipsets have limited OpenWrt supportability (due to limited FLOSS driver availability for Broadcom chips). Consider this when choosing a device to buy, or when deciding to flash OpenWrt on your device because it is listed as supported. See Broadcom WiFi for details.
