Orange pi R1 plus support

I have a Redmi AC2100 router and I tried openwrt in it. Of course it's much better than stock rom but there's a small loss in wifi signal that stops me from using it. As i don't like signal expanders and all that network switching I'd like to put a device in-between my ISP router and the redmi to use this lastone only as AP. I found this new orange pi R1 plus, with rkc3328, twin gigabit ports and 1gb ram and was wondering if there's really support for it, as it's claimed in AliExpress shop. Anyone has already tried it?
