If it pairs in the same room then it should pair in the other room. You did not say if you are in the US or have the US type of wiring which is 110 volt and 220 volt made up with two 110 volt circuits. Sometimes power devices like this and others like X10 have issues when attached to one side and the other device is attached to the other side of the circuits which may be the case here. Try different outlets through out the house and see what works. There are devices for X10 to bridge the two which may work. If you decide to replace your units, look into the true Mesh system as that is much better than using extenders or APs.

Thanks!  I am in the U.S. and after updating Firmware everything started working again.  I will be upgrading one of these days and will look into the Mesh units as you suggested.
