GL B1300 Repeater vs Mesh mode to bridge my internet connection to another ethernet switch.?

I have two B1300 that I want to provide WiFi from one of them and was thinking I would use the second one as a repeater so I could connect an Ethernet cable that connects to a switch that other devices without WiFi could access the internet, like bridging from one to the other. I set it up in Repeater mode but that one loses its config every so often. I went back and reread the online documents and was wondering if I should be using them in a Mesh instead? I am not sure if it will still act as a bridge once they are both in mesh mode. -Bill
