@Petr89 Go to Russia and buy AX73 with RU region. TP-Link routers are very difference depending on the region.

@terziyski How can I ask question to Tp-Link Representative?

@terziyski But Archer C6U(RU) (Russia region) has this feature. Why is this feature missing for users at Europe region? The users at Europe region also want to use the USB 3g/4g modems with this...

Hi, How can I connect a USB 3g/4g modem to Archer C6U(EU) router? The menu Advanced > USB Sharing has no item 3G/4G. Thanks.
