I have an Airport Extreme connected to the internet and a handful of Extremes/Expresses extending it wirelessly. It works OK. But when I connect one of the extending devices with an ethernet cable - on the theory that wired is better than wireless - things go awry. (My primary Airport Extreme starts dropping the connection, devices show that they are online, but they are not, etc. Basically, the network stops working.)
Once thing that I do that I'm not sure of is that I plug those devices into a switch as opposed to directly into the primary Airport Extreme. So my question is: Is this OK to do?
Thank you in advance!
