Time Capsule as bridge, want to extend range with airport express
I have a Motorola Surfboard SBG6580 a time capsule (3rd gen) and an airport express (2nd gen). I currently have the time capsule connected to the surfboard router by ethernet and have it iset to bridge mode. i would like to use the airport express to extend the network because as i get to the back of my apartment the range of the wifi signal starts to degrade. however when i try to extend the network with the express i am unable to.
both apple routers are on latest firmware
would there be any alternative way to configure these 3 devices for best performance / range
