Hello everyone,

I am facing a severe issue with my Archer AX12(EU) Hardware Version 1.0 router. The device became corrupted during an update, and I am currently stuck trying to recover it. I have spent hours troubleshooting this alongside Gemini AI, and we have exhausted the standard methods. Gemini helped me compile this comprehensive summary of everything tried so far to see if the community's technical experts can spot what we are missing.

Here is exactly what is happening and the technical roadblocks encountered:

1. The Web Browser Recovery Failure

I can successfully boot the router into its built-in emergency web recovery interface (192.168.0.1) by setting my PC to a static IP of 192.168.0.10, holding the WPS/Reset button, and powering it on. However, the internal web server engine appears completely unstable:

• I am trying to upload a clean, extracted official factory .bin firmware file (specifically version v1.1.28).

• I shortened the filename to a single character (e.g., a.bin) to prevent any buffer overflow in the router's memory.

• The transfer is abruptly aborted mid-way, and every browser fails at a different percentage: Microsoft Edge consistently disconnects and freezes at exactly 14%, while Mozilla Firefox consistently drops the network interface at exactly 40%.

2. The TFTP Recovery Failure

Because the web interface keeps interrupting the connection, I tried to bypass the browser entirely by forcing a hard firmware push using TFTP server software (Tftpd64 and SolarWinds TFTP).

• My environment is fully isolated: Wi-Fi is completely disabled, and Windows Firewall is turned entirely off.

• I have tried binding the TFTP server to static IPs 192.168.0.66 and 192.168.0.10.

The Obstacle: My TFTP server log files remain completely empty; the router never hits the server. Please note that I am blind, so I cannot visually monitor the behavior, blinking patterns, or color changes of the front panel LED lights to time my button releases. I am relying strictly on manual counting. It is highly likely that without being able to see the flashing lights, my physical timing on the WPS/Reset button is slightly off, causing the router to default back to the broken web UI or a standard boot loop instead of triggering TFTP mode.

Questions for Community Experts & Moderators:

Since the browser method crashes mid-upload and I cannot rely on visual cues to time the bootloader sequence, I need the exact technical specifications for this specific Realtek hardware layout to get TFTP working blindly:

1. Is there a known way to force the web interface (192.168.0.1) to finish the upload without the connection interrupting? Are there specific browser configurations or alternative steps to stop the network stack from dropping mid-way?

2. What is the exact factory filename string this bootloader queries during a TFTP pull? (Is it ax12_tp_recovery.bin, tp_recovery.bin, Meboot.bin, or something else?)

3. What is the exact static IP address the router expects the host TFTP server to hold? (Should my PC be set to .0.66, .0.10, or something on a .1.X subnet?)

4. What is the exact button-press timing sequence to force TFTP mode? For a non-visual setup, how many seconds after plugging in the power cord should I hold the WPS/Reset button before releasing it to ensure it sends a TFTP broadcast instead of launching the web interface?

If any forum regulars, moderators, or anyone who has successfully unbricked an Archer AX series device via TFTP can provide these exact parameters, I would be incredibly grateful.

Thank you for your time and technical insight!
