TP-Link ERROR-8005 on Wi-Fi router: firmware upgrade failed
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Medium
Quick answer
Error Code 8005 on the TP-Link web management page appears when a manual firmware upgrade uses an incorrect or unextracted file. Extract the downloaded folder to select the .bin file and verify that it matches your exact model number, hardware version and region.
Safety first
Stop and check this first
- Never unplug or power off the TP-Link router during a firmware upgrade: TP-Link warns that a sudden power outage during the upgrade can brick the router.
- Only download firmware from the official TP-Link website for your purchase region; using another region's firmware can cause upgrade failures and void the warranty.
Safe checks you can perform
- Verify model number, hardware version and region on the label
- Extract the downloaded archive and upload the .bin file
- Wait 5 minutes if stuck or switch to Firefox, Edge or Chrome
- Test online firmware update with manual DNS 8.8.8.8 or 1.1.1.1
Leave these tasks to a qualified professional
- Do not attempt this professional task: Firmware verification with TP-Link Technical Support
- Do not attempt this professional task: Webpage firmware recovery or warranty service after power loss
What a technician must be able to justify

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Firmware verification with TP-Link Technical Support
What they doIf Error Code 8005 persists even when uploading the extracted .bin file for your exact model, hardware version and purchase region, TP-Link Technical Support verifies the required upgrade path.
They must show youthe verified firmware file version that matches your hardware revision and current build.
In writingthe TP-Link support ticket reference and the official upgrade instructions provided.
Webpage firmware recovery or warranty service after power loss
What they doIf a sudden power outage occurred during a firmware attempt and left the router unresponsive to normal web login, TP-Link support guides you through webpage firmware recovery or warranty service.
They must show youwhether the router enters webpage firmware recovery and boots cleanly with the restored firmware.
In writingthe support incident summary or RMA authorization if hardware replacement is required.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Verify model number, hardware version and region on the label
- Who:
- you.
- How:
- check the product label on your TP-Link router to confirm the exact model number, hardware version (for example V1 or V2) and regional version (US or EU) before selecting a download on the local TP-Link website.
- Result that matters:
- ensure the downloaded firmware package matches your physical hardware.
- If the downloaded file was for a different hardware version or region:
- download the matching package from your local TP-Link site.
- If the model, hardware version and region already match:
- check that the archive has been extracted.
- Evidence to keep:
- photo of the router label alongside the downloaded archive filename.

Extract the downloaded archive and upload the .bin file
- Who:
- you.
- How:
- unzip the downloaded firmware folder on your computer first, and in the TP-Link web management upgrade page select the extracted .bin file rather than the compressed archive.
- Result that matters:
- provide the exact .bin file format required by the TP-Link web interface.
- If the upgrade accepts the .bin file and completes:
- allow the router to reboot normally.
- If Error Code 8005 or 'unable to upgrade' still appears:
- test another web browser.
- Evidence to keep:
- screenshot showing the extracted .bin filename selected for upload.

Wait 5 minutes if stuck or switch to Firefox, Edge or Chrome
- Who:
- you.
- How:
- if the progress bar stalls, wait up to five minutes before acting; if it does not finish, refresh the web page and try the upgrade again using Firefox, Microsoft Edge or Chrome.
- Result that matters:
- rule out a browser session hang during local firmware upload.
- If the update completes in the alternate browser:
- confirm the new firmware version in the web GUI.
- If manual upload still fails:
- try an online update after setting a public WAN DNS.
- Evidence to keep:
- screenshot of the firmware upgrade page showing the error message or progress bar.

Test online firmware update with manual DNS 8.8.8.8 or 1.1.1.1
- Who:
- you.
- How:
- if your router supports TP-Link Cloud and has active internet access, set a static DNS server such as 8.8.8.8 or 1.1.1.1 in the router WAN/Internet settings and run the online upgrade option.
- Result that matters:
- let the router fetch the matching firmware directly from TP-Link Cloud.
- If the online update succeeds:
- no manual file upload is required.
- If both online and manual upgrades fail:
- contact TP-Link Technical Support with your version details.
- Evidence to keep:
- screenshot of the current firmware version and WAN DNS setting in the router interface.

What it means
According to official TP-Link support guides (FAQ 2657 on web management page error codes and FAQ 2571 for routers such as Archer AX10, AX21, AX50, AX55, AX73, AXE75 and C50; other models may vary), Error Code 8005 ('Firmware Upgrade Failed' or 'unable to upgrade') occurs only when the device firmware is upgraded with an unsuitable file. It is typically triggered by uploading the compressed archive instead of extracting the .bin file, or selecting the wrong hardware version or regional build (US vs EU). This code alone never proves that your TP-Link router is faulty.
