My office will never deploy a WiFi bridge since we never found them to be stable enough. On top of that you are at the outer limits of WiFi.
You'll have to test it out and see if it will do for your needs.
I'm setting up a ≈100m wireless connection from another house to mine. I have an N300 router available and the possibility of getting a second low-end router. My question is: would it be best to use the N300 router in wireless bridge mode alone, or have it run client bridge connected via ethernet to a second router which sets up the wifi in my house?
