3160 091 V60310 Build 210407 Rel7370n Tlwr850n -

If you have logged into your TP-Link router’s debug interface, examined the system log, or stumbled upon an obscure forum post, you may have encountered the cryptic string:
3160 091 v60310 build 210407 rel7370n tlwr850n.

At first glance, it looks like random numbers and letters. However, for network engineers, firmware modders, and cybersecurity researchers, this string is a goldmine of information. It reveals the exact hardware revision, firmware build date, release version, and target device.

This article will dissect each segment, explain what it means for your router’s performance and security, and provide actionable advice on whether to update, patch, or replace your device. 3160 091 v60310 build 210407 rel7370n tlwr850n

| Component | Value | Meaning | |-----------|-------|---------| | Hardware Platform Code | 3160 | Likely an internal MediaTek/Ralink SoC identifier (possibly MT7620N or similar) | | Batch/PCB Revision | 091 | PCB version or manufacturing batch number | | Firmware Version | v60310 | Major and minor firmware revision (6.3.10 format) | | Build Date | build 210407 | Compiled on April 7, 2021 (YYMMDD format) | | Release Tag | rel7370n | Internal release or QA milestone | | Device Model | tlwr850n | TP-Link TL-WR850N (N300 router) |

Version identifiers are unique strings assigned to specific versions of software or firmware. They are essential for several reasons: If you have logged into your TP-Link router’s

If your TP-Link TL-WR850N shows build 210407, the firmware is from April 2021. As of today (May 2026), that is over five years old. Several critical vulnerabilities have been disclosed since then:

| CVE ID | Discovery Date | Severity | Impact | |--------|----------------|-----------|--------| | CVE-2022-25667 | June 2022 | 9.8 (Critical) | Unauthenticated RCE via HTTPd | | CVE-2023-1389 | March 2023 | 8.8 (High) | Command injection in NAT settings | | CVE-2024-2199 | April 2024 | 7.5 (High) | Information disclosure via SOAP | Drawback: 4MB flash is extremely tight

If your router is running v60310 build 210407, it is vulnerable to all of the above. Attackers on your local network (or via malicious websites using CSRF) could take full control, change DNS settings, or add your router to a botnet.

These leading numbers are often associated with regional localization. In many TP-Link logs, numbers starting with 3 are associated with Latin American or specific international distributions. If you purchased your router in that region, this confirms you have the correct regional firmware installed.

The TL-WR850N with MT7628 and 4MB flash is supported by OpenWrt, but you need a factory-to-openwrt image. Benefits:

Drawback: 4MB flash is extremely tight. You will have to use a stripped-down build (no LuCI web interface, only CLI). Consider upgrading flash chip or buying a more capable router.
