Good Day,
I'm in an older house and have a DIR-655 in the basement as the main router (DHCP on).
I have an DIR-825 on the main floor as a secondary (DHCP off):
655-> LAN Port 1 out.... into LAN Port 1 of the 825
Everything is working fine except for the Guest Zone on the 825 - it doesn't seem to be working.
I do get internet access when connected to the secured wireless off the 825 though.
As it's an old house, there is almost no wireless signal between floors, hence the multiple routers

Any help is greatly appreciated.
Much thanks,
