Hello
I own a RB2011UAS-2HnD-IN and I want to connect to another wireless router so I could have wireless network to the other side of the house.
So I have the following topology:
Internet - cable connected to - Asus router with wireless -> Mikrotik RB2011UAS-2HnD-IN
I am a beginer that wants to connect wirelessly my RB2011 to the Asus router on the outher side of the house.
And then if is possible to share the internet through RB2011 to my devides.
Thank you!

There is no universal repeater function in ros. You can use wds in Ap bridge mode but it is hard to say if it will work with your Asus. I would run cable between instead sharing one frequency and one of the radios for two purposes. You can use Rb2011 as main router and load openwrt into Asus and set Asus as universal repeater.
