Interesting - glad you found it. Only 4 ports here, and no other wires
between the two, so can't be a 'wire loop'. But, since the two have the
same SSID, could there be a 'wireless loop' between the two even if
the channels are different?

I was not sure what you meant by this, but when I checked the ASUS
website they mentioned an option to set up as an access point. I will
try this if I have that setting on the router. I also saw a suggestion
to reset to factory defaults before setting it up as an access point,
which I did not do. Maybe there could be some obscure setting or history
that is causing a problem. I'll try this.

Any idea why the Ubuntu box refused to be the desired local master
browser, based on how the routers were connected?

Thanks..
