My router is a AC56U and I wanted to update it. I downloaded the correct version RT-AC56U_380.65_0.trx from the mediafire host. Now when I go to the Firmware Upgrade tab on my router an select this file the procedure starts and runs until it hits 100% and tells me it was successful. The browser refreshes and I'm back at the network map page but the firmware is still 376.49_5. I tried it now a couple of times with a reboot before I update and with a different browser (FF and Chrome) but no luck every time the same thing happens or to more precise seemingly nothing happens. Now I'm out of ideas
