OpenWrt support for Netis N6 router

Need openwrt os for Netis N6 router

Who doesn't.

Same device?

Using zoom pdf at the site I could barely make out that it has Mediatek chips.
This site suggests that it is MT7621 based:

It potentially is doable and there are 2 Netis MT7621AT devices already in the data base. If you are lucky you may just need to update the wifi modules and the partition scheme: 16MB for the N6 vs 128MB for the other devices.
