Custom Firmware | Huawei Hg658 V2

Here’s a structured guide on custom firmware for the Huawei HG658 v2.
Important note upfront: the HG658 v2 is a less common router, and custom firmware support is very limited compared to Broadcom-based models. Most efforts focus on unlocking features (e.g., full bridge mode, VPN passthrough, or ADSL stability) rather than full third-party OS replacements like OpenWrt or DD-WRT.

1. Configure the WAN port

  • Go to Network → Interfaces.
  • Edit the WAN interface.
  • Set protocol to PPPoE (or DHCP) and enter your ISP credentials. Connect your external VDSL modem to the physical blue WAN port.

4. How to flash (generic method for unlocked firmware)

The Reality Check: VDSL Modem vs. Router

This is the most critical part of understanding Huawei HG658 v2 custom firmware.

The HG658 v2 uses a Lantiq VR9 chipset for its VDSL2 modem functionality. In the open-source world, support for this chipset is "OK" but not perfect. Most custom firmware (like OpenWrt) will disable the internal VDSL modem because drivers are either proprietary or unstable. huawei hg658 v2 custom firmware

What does this mean? If you install custom firmware, you will likely lose your telephone line (DSL) port functionality. The router will become a pure Ethernet router/switch/Wi-Fi access point.

To connect to the internet via VDSL/ADSL after flashing, you would need a separate VDSL modem (like a DrayTek Vigor 130 or an old TP-Link modem in bridge mode) plugged into the WAN port. Here’s a structured guide on custom firmware for

Unlocking the Potential: The Ultimate Guide to Huawei HG658 v2 Custom Firmware

The Huawei HG658 v2 is a dual-band ADSL2+/VDSL2 router often provided by Internet Service Providers (ISPs) like TalkTalk, Plusnet, and others across Europe. On paper, it’s a capable device: 802.11n Wi-Fi, Gigabit Ethernet, and a built-in VDSL modem. In reality, the stock firmware is notoriously locked down, buggy, and lacking in features.

This is where Huawei HG658 v2 custom firmware comes into play. Flashing a custom firmware can transform this aging gateway into a powerful, flexible routing machine. However, the process is fraught with risk and specific requirements. Go to Network → Interfaces

In this article, we will explore what custom firmware exists for the HG658 v2, the benefits, the dangers, and a step-by-step guide to the most popular option: OpenWrt.

2. Gather the Correct Firmware

  • Look for “HG658v2 V100R001C03B032” (a common base). Avoid anything labeled “V100R001C01B0xx” – that’s for v1.
  • Search forums like 4pda.to (Russian) or Huawei-NSA.ru for “HG658v2 custom mod”. Look for files ending in .bin or .trx.
  • Never flash OpenWrt or DD-WRT – they won’t boot.

2. Fix Wi-Fi Speed

  • Go to Network → Wireless.
  • For 2.4GHz, select radio0.
  • Under "Advanced Settings", set Country Code to your location (to enable legal channels).
  • Install the wpad package (for WPA2) if missing: opkg update; opkg install wpad
