Hello,
i got Archer MR400 router and i have a problem connecting to 4G network, it just doesn't connect at all, only 3G mode working. My ISP provider is Kyivstar(Ukraine).
Signal is okay and also i have tested SIM card in cell phone and 4G is working. I don't know what else i can try to make it work, please help.

When i set 4G Mode constantly getting connection error, screenshot http://prntscr.com/kvm4cc
Same profile used for 3G and its working, screenshot http://prntscr.com/kvm4no
