You should make sure the APs don't interfere with each other. The automatic channel selection didn't work well for me. I had to manually set my two APs at each end of the 2.4GHz spectrum. It's also a good idea to turn on wide band channel. If you have an Android device somewhere you can download wifi analyser to make sure the channels don't overlap.
