hello, Lately my extender has been very slow with the devices connected to it. I have an AirPort Extreme downstairs hooked to the modem with a power line adapter to it as well, then I have an airport express upstairs hooked to another power line adapter to speed it up... However it's not working... I'll get 40-90mbps on the main station and only 1-5 on the express. How can I extend this network better? I've read online that you need to see it up as its own network using the same network name and password and change a setting "connect via Ethernet" but that setting is not to be found... Can anyone help me so I can get my speeds back?
