I'm not super versed in networking and realized after running wireless setup-repeater that this doesn't allow for a device connected on the ethernet to connect to the internet. I want to use the wireless repeater feature to extend my network on a far point of my house, with seemless roaming, however I also want to use the ethernet on this device as well. How can I do this? main home router is a Netgear and detects as pseudo-bridge. Repeater device is a wAP.

Maybe try creating 2 WIFI interfaces one station other AP, than bridge all together, you will have internet on LAN port, and you can also create another WIFI network with same SSID which would act as it was repeated.

The best solution is to use the AV2 powerline adapters if you cannot wire the wifi APs up.

You need to bridge the ethernet interface to the SSID if it is possible, if not you can always use routing.

Go into the device managment interface (either web or winbox), navigate to bridge menu and to ports tab. There add the ethernet port(s) you want to connect your device into, to the existing bridge interface. Voila!
