Hi, I’m new to the Mikrotik Routerboard and actually new to networking in general but getting through it slowly. I’m in the process of setting up a wireless hotspot and have configured a RB751G and it’s working perfectly. I have it configured so that users can enter a guest password and can then browse the web. I now want to extend the wireless network by adding an additional two RB751G’s. I would like to broadcast the current RB751G wireless network to cover a larger space. Can someone point me in the right direction? As I said, I’m new to this but trying to learn as much as possible in the process. I would google it but not even sure what I’m looking for. Let me know if you need any additional info. Thanks in advance. Newbie. 
If you can’t run a cable between them this would be your best bet.
