I currently have the latest Airport extreme and about 4 expresses. I am having a load of trouble with wifi. We have a lot of things that connect to the network. 2 appleTV, 7 thermostats, 2 smoke detectors, 3 ipads, 2 game consoles, 2 phones, probably a few other things I am forgetting. I am really not positive that just the network is the issue, I may have an ISP issue as well. I started researching a replacement router. The Netgear Orbi, seems like it would be a good fit. Anyone using these or a similar device. I can't hard wire between the two stations, so that negative for the Orbi does not matter to me. This device seems like a better option than my extreme and express extenders. I may still leave an express on the netwrok for down by the lake. Surprisingly the trend-net thing and express that are farthest from the house seem to be the most stable stuff I have. All firmware is up to date.
