✅ Backup your current settings. ✅ Download the exact firmware for your hardware version. ✅ Use an Ethernet cable. ✅ Disable antivirus/firewall temporarily. ✅ Wait for the automatic reboot (do not manually power off). ✅ Reset to factory defaults after the update.

The D305’s hardware is capped at ADSL speeds (24 Mbps downstream). If your new internet plan exceeds this, or uses a WAN Ethernet port (fiber box), you must replace the router entirely. Check with your ISP: If you have a separate Optical Network Terminal (ONT), you should use a standard Gigabit router, not the D305. Updating the software on your TENDA D305 is a straightforward but high-stakes procedure. By downloading the correct file from the official TENDA website, using a wired connection, and never interrupting the power cycle, you can breathe new life into your router.
