Installed my new RT-AC86U today from major USA retailer. On first power up, on upper r/h corner has to flip the language from Chinese to English. The docs in the box all Chinese, no English docs...hhmmm.
Firmware that installed itself was 3.0.0.4 384_20308. After a factory default reset via panel, then via WPS button (did both...) then installed Merlin's 384 beta 3 which had just came out for the AC86U. After a factory default reset and power up, came up in Chinese language and no way to flip to English. I just entered data in panels to get to the home panel, then in the upper right panel, then a language option to change from Chinese to English. But this didn't work, soon as I select English, forced off the browser connection and when I logged back on again via Chinese language logon panel language, Home panel still showing Chinese.
I then installed Merlin's older firmware 382.1_2 and after a factory default reset it came up in Chinese language again. But this time hacking through to the Home Panel I was able to change the language from Chinese to English which occurred immediately!! (yippee...)
That was some excitement I didn't need to a Sunday evening, any ideas what's going on here and to avoid a repeat? Attached the first two screen panels you always get on power up, then the Home Screen in Chinese.
