I also just flashed ArcherC7v2_en_us_180114.bin onto my V3 (US purchased) and it booted back up and seems fine. The update reset me back to factory settings so I had to set things up again, but...

I want this answered too. V2 and V4 have updates within the last few months. What happened to V3?

tp-link: can someone please post something to the FAQ or otherwise answer why there is no firmware update for the Archer C7/AC 1750 v3 firmware? I see that the V2 and V4 firmware both have updates...
