I have used for years a good number of TP-Link TL-WR841N routers with OpenWRT and I've been very happy with them. Recently I bought a batch which turned out to be v13, which has a number of pending issues with OpenWRT - so I can't really use them at the moment.
I ordered a TL-WRN940N - seeing as it is supported by OpenWRT. As luck would have it, when it arrived, it turns out that it is v6.1. This is not even mentioned anywhere on the OpenWRT website, and I can't figure out if it is supported. I tried flashing it through the OEM interface with 18.06.1 and with a current snapshot - but I get:
"Error code: 18005
Upgrade unsuccessfully because the version of the upgraded file was incorrect. Please check the file name."
I've tried flashing it with TFTP as well, but nothing appears to be happening - at least it doesn't seem to be requesting any file from the tftp server on the computer. It is a bit hard to tell what is going on, as this router only has one multicolour LED on the front.
Has anybody encountered this router yet, and do you know if it is the same as v6, and if it is supported?
Many thanks for any info.
