Executive Summary

The ZTE F6640 is not a standard retail router you buy on Amazon. It is a carrier-grade Wi-Fi 6 gateway (often branded as "ONT" or "HGU" – Home Gateway Unit) primarily supplied to Internet Service Providers (ISPs) like Vodafone, T-Mobile, or local fiber operators.

Verdict: Excellent hardware (Wi-Fi 6, Gigabit ports) crippled by locked-down ISP firmware. It is a fantastic router for the average user who never changes settings, but a frustrating paperweight for power users.


Important Note for Power Users:

Unlike many ISP routers, the F6640 supports Link Aggregation (802.3ad). If you have a NAS or a high-end PC with two network ports, you can combine two of the GE ports to get a 2Gbps wired connection to a single device, bypassing the 1Gbps limit of a single port.

3. Basic configuration

  • WAN/Internet: use PPPoE if your ISP requires it — enter provided username/password.
  • DHCP: keep enabled for LAN devices (default is fine).
  • Set correct time zone under System Settings.

A. Bridge Mode (Use your own router)

  1. Log into web interface.
  2. Go to Network > WAN.
  3. Find the existing TR069 or internet VLAN connection.
  4. Delete or disable it.
  5. Create new WAN:
    • Mode: Bridge
    • VLAN ID (ask ISP or look at old config – e.g., 835, 101).
    • Port binding: LAN1 (or all LAN ports).
  6. Save and reboot.
  7. Connect your router’s WAN to ZTE LAN1, set PPPoE/DHCP on your router.

1. First Impressions and Design Philosophy

At first glance, the ZTE F6640 breaks away from the typical "spider" design of consumer routers. It adopts a sleek, tower-like vertical form factor.

  • Dimensions: Approximately 23cm tall, which helps with passive cooling and space-saving on a desk.
  • Build Quality: Matte black ABS plastic with a perforated vent design on the sides to prevent thermal throttling.
  • LED Indicators: A minimalist smart LED bar on the front that changes color to indicate status (Green for normal, Red for no signal, Yellow for degraded sync).

Why the vertical design? ZTE engineers have optimized this for thermal dissipation. Unlike flat routers that trap heat, the F6640 uses convection currents to pull cool air in from the bottom and expel hot air out the top. For users putting this in a cabinet, this is a breath of fresh air.

6. Weaknesses: The Trade-offs

No device is perfect. The ZTE F6640 has a few quirks:

  • No 6 GHz Band (Wi-Fi 6E): This is a purely Wi-Fi 6 router. It does not support the new 6 GHz spectrum, which means more interference in apartment blocks.
  • No 2.5G Ethernet Port: In 2024/2025, high-end routers often include a 2.5Gbps WAN port. The F6640 sticks to Gigabit, meaning you cannot fully utilize fiber plans above 1Gbps (if your ISP offers 1.5Gbps or 2Gbps).
  • ISP Locking: Depending on your provider, the F6640 might be locked down. Some features (like bridge mode or DNS changes) may require a call to technical support for a "super password."
