Downloaded and tried 1.0.6 as well. It also failed saying it was an invalid file.

Hello. I'm stuck. My TL-SG3210XHP-M2 v1's are running 1.0.15. Got a notification on my controller (5.15.8.1) that 1.0.16 was available. Attempted to update and it failed. Post failed update switches...

@Vincent-TP Updated. All went well. Web UI seems more responsive when accessing locally. Cursory check though options seems everything it working. Merry Christmas!

@McFly82 Did you check what speed the ports negotiated to make sure its not 10/100 for some reason? can you replace the cable to verify its not a physical issue?

Updated. No issues thus far. Wasn't experiencing the issues referenced in release notes so can't speak to the fixes.

@Clive_A Thanks, but the link to the beta firmware for the ER8411 in the post was only to the bin file so there weren't any release notes to reference controller compatibility....
