Extend LAN to existing wireless network

I have an existing wireless network (Cisco router) in my home. Due to the layout I can’t run ethernet cables everywhere I need them.

So, I have this MikroTik haplite lying around and I’m wondering if I can use it to solve this problem. Basically, it would sit there with a couple of desktops (no wireless cards) plugged into it, and bridge them onto the wireless network so they have internet access.

Is this even possible? Where do I start?

Yes. Use wireless client mode, read in manual about it.
