I am using a cable modem, then plugged into the main Deco M5, then an 8 port switch (with local devices connected) and then a 50 foot run of cat 5 (out of one port of the switch) to the other end of the house with another 8 port switch and then the second Deco M5 plugged into that switch plus other local devices plugged into that switch.

If I only use the one switch at the remote Deco M5 everything works great, but if I introduce the switch after the main Deco M5 I lose everything at the remote switch.

Any ideas ?

Thanks in advance!!!
