Ar-750s-ext can't upgrade to 3.201


I have two routers which I did not used for awhile, a 300M and a AR750S-ext.
I connected my laptop to the 300M and upgraded it to 3.201 without problems.
Then I wanted to upgrade the AR750S-ext from 3.104 to 3.201 also, but it fails. Even when downloading the FW manually it returns "Incorrect firmware format’.

What am I doing wrong?

thank you Tom

Please upgrade from 3.104 to 3.105 and then 3.105 to 3.201

There was an issue and this process will complete the upgrade.

Hope this helps.

Yes, thank you so much for your quick reply. That did the trick.

Internet and the people on it can be so wonderful.

thanks again
