GL-AR750s-ext firmware verification fail

alexa · 2021-10-19T15:02:37.201Z

Hello

When I try to upgrade the firmware of a GL-AR750s-ext router, from version 3.101 to 3.203 I get an error that verification failed.

The router says the MD5 sum is “01cdd4dd9d1d528414bd04754e1df0fe”

Please can you help?

Thanks

I used the web admin’s online upgrade option and pressed Download

Please upgrade to 3. 105 amd then to 3.203.

You need to say which file you used.

There is .tar and .img file. You need to use .tar file.

Thank you sorry I used the .img file, the .tar file upgrade to 3.105 worked
