Hello.

I don't have much knowledge about networking, so i'll try to explain my problem the best I can.

I've purchased the Deco M4 (2 units).

I have modem-router combained that connects directly to my pc via cable, and I've pluged the Deco to other Lan connection on the modem-router.

The Deco created a seperate wifi network from my existing wifi from the modem-router.

So I have two wifi networks that works at the same time.

My issue is when I wants to connect my printer wirelessly to the Deco. When I plug it to the Deco's wifi the printer connects but there is no connection between my pc to the printer, because my pc connects directly to my modem-router. And when I connects the printer to the modem-router's wifi, there is connection between the pc and the printer.

I've been told that's because my modem-router and the Deco works in different networks. 

P.S. 

I tried to set the Deco as an access point and it worked, but it feels laggish compared to router mode.

So I prefer to stay in router mode if it's possoble.

There is any solution?

Thanks :)
