Router: 2 WAN - Cable/DSL (Corbina/MGTS), Gigabit Ethernet, WiFi (802.11n)?

Question

WiFi

Actually the subject is necessary.
Preferably with load balancing between providers.
Has anyone found such devices?

Answer 1

There is such a monster www.thg.ru/network/draytek_vigor_2820vn/index.html.
I didn’t touch it myself, as it was not necessary.

Answer 2

It is better to collect on an old computer or use a microtik routerboard. The maximum that you can squeeze out of the router is about 700 Mbps (LAN-> WAN). If you don’t need a gigabit WAN, but only need gigabit in LAN, then any fast router will do, on which you can install dd-wrt or openwrt.
700 Mbit WAN can be achieved using D-Link Dir-685 (~8000 rubles) and Draytek Vigor 2130n (~10000 rubles).
