Today I was hoping to setup a network extender. I want it to connect to my router via ethernet, and then share out that connection via WiFi, and stay on the same network. All of the tutorials I looked at configured it in a way that the connected devices are on their own network with the raspberry pi, whereas I want mine to connect them to the 192.168.1.0/24 subnet. Is there anyway I can do this?
Thanks!
It seems that you only found setups, using routing. But it is no problem to setup the WiFi access point on the RasPi to be on the same internal subnet as the internet router. You have to bridge the wired connection to the router on eth0 with the wlan0 interface of the access point. This way you are even on the same broadcast domain as the router, so your clients connected by WiFi will also use the DHCP server from the router. And it will give all clients ip addresses from the same subnet. How to setup it just have a look at Setting up a Raspberry Pi as an access point - the easy way. Beside the other options using routing you should follow the section ♦ Setting up an access point with a bridge.
