Hi, I'm not really that familiar with networking. I just know the terms and some basic knowledge. Somebody did the setup of the network for me.

Basically, the setup of my network is a WAN connected to Router 1 and a switch connected to the LAN port of Router 1 and Router 2 acting as an AP is connected to the switch. Problem is, the wireless connection keeps dropping so I wanted to change the channel. However, I don't know the IP address of Router 2, so I thought I would just do a factory reset on Router 2. If I do that how do I configure Router 2 act as an AP again?

Router 1 is a Peplink Balance 310
Router 2 is a D-Link DIR-615
Switch is a 3COM Baseline Switch 2024
