Lets call my home router 'HomeAP' and the network brdge (OpenWRT) in the far end of the building as 'Repeater' connected via wifi. Both have different SSID and my rPi is connected to the Repeater via ethernet cable. Although the wifi signal from HomeAP is a lot stronger, i am able to connect to both SSIDs where i usually have to connect to Repeater in order to interact with the rPi via SSH. Due to the weak signal, the connection is usually slow and get disconnected fairly often which can be really annoying.
MyComputer >>(wlan0)>> HomeAP >>(wifi/bridge)>> Repeater >>(eth0/LAN)>> Raspberry Pi
I am running Debian on my computer and the rPi is on Raspbian while HomeAP is on stock (busybox) firmware. At the moment i need to disconnect myself from HomeAP and connect to Repeater wifi in order to SSH into rPi. Hopefully i can improve this experience and be firmly connected to the Raspberry Pi.
How can i connect to the rPi that is located between 2 routers from or through HomeAP (better stabled connection from stronger wifi signal) and if there is any better configuration that i should look up into?
