Hi,

Do you know how your AX50 got to this firmware version 1.0.8 Build 20200430 rel.34131(4155)?

This build doesn't appear to be a regularly released firmware version.

Is your AX50 a normal retail version bought in a store or was this AX50 part of a broadband Internet connection package of a local ISP?

Has the firmware ever been changed since the router came out of its box?

Have you previously had TP-Link support work on this AX50 to fix some problem?

  @terziyski I've tried to upgrade the firmware with the US and EU versions of the firmware and both give me the error.

  @woozle the router is a standard retail version I bought from a store.

I do remember upgrading the firmware once after I purchased the router with a firmware that was available from the AU TP-Link website. Then I noticed a few weeks later that firmware version was no longer available which I thought was strange.

With every subsequent firmware release on the website I have tried to upgrade and has always failed. I emailed support once about the issue and their answer was along the lines of 'why do you want to update your firmware, you should only update the firmware if you have issues, do you have issues?'. I didn't have connectivity issues at the time so I left it but now because I see there's a few updates since my version, I want to ensure my router has the most secure update.

Ok, I see.

I think this can only be solved by TP-Link support.

Obtaining the latest security fixes should be reason enough for updating the firmware of a router.

  @mjalb88 Did you ever get a solution to this from Customer Support?  I have the same firmware version and the same upgrade inability and I think it may be behind some VPN problems I've been having.

Thank you for sending through the beta firmware via email. My unit is the US version so it installed successfully and I've been able to upgrade to the latest US firmware now.
