Which WiFi repeater do you have? Any model number or?

Not sure if this is what you need, but this is what it says on it:

wireless-n repeater

Connect your ethernet cable and it should be fine? What's your problem?

It's not that difficult, make sure you connect the Ethernet cable, also from your main router you should see advancing setup or settings. I can help if you want.

Wait so i put the Ethernet cable into my router into my repeater?

Yep. Looks like the repeater isn't a WiFi repeater.. more like a hotspot.
