Same here, after loosing the ability to log in (not 80 mgmgt port) I reverted my C7v1 to the 140704 FW ;)

I think it actually got fixed in the V1 July firmware release ;)

yes, true that. From what I've spoken directly with TP-Link dev in China the bug was a minor concerning the 5GHz at all f*ck up. I will contact him and ask whether our WPS bug will move now from...

Official Archer C7_V1_140402 stable firmware is available for download http://www.tp-link.com/en/support/download/?model=Archer+C7&version=V1

changelog?

bug has been confirmed by TP-Link support and forwarded to developers.
