Hello,
when i use Quick Set to change router's ip address from eg. 192.168.88.1 to 192.168.23.1 it does not update DNS server address advertised by DHCP server, so all computers in network still get configured to use 192.168.88.1 as primary DNS even if there's no such machine. I think that quick set screen should handle this if it is supposed to be usefull for newbies. Otherwise it's really confusing and i've been fooled by this several times until i've noticed where is the problem.
