How to configure yota modem on RT-AC66u

[Novakin]

Hi guys,

I'm using the last merlin firmware on my RT-AC66U and i would like to use a Yota 4G LTE modem for dual wan.

i followed this : http://www.profitsnab.ru/articles/ASUS_RT-AC66U_Yota_LTE.htm so my modem would be recognized,

Now i'm kinda stuck. i have tried to configure it with Russia > Yota > yota's mail account for username and yota's password as password, it didnt work

I also tried manually with WCDMA

It didnt work also

Anyone could do that and willing to help me ?

Thanks
