Model : Archer C7

Hardware Version : Not Clear

Firmware Version : Archer C7_V2_150427

ISP : TM Unifi

before i upgrade my AC1750 wifi router to the latest version, i was using the following firmware version:
3.13.34 Build 140704 Rel.4047n.
after i upgrade the latest firmware for V2, i cannot establish my Unifi connection. i am sure my username and password is correctly input.

I try to flash back my firware to the previous version, but i can't find it in the download section.
anyone has the 3.13.34 version firmware, please send it to me.

Thanks !
