I did try the WGR614 without java-script enabled on
my browser.

I didn't write down the exact wording but
the gist of the error message was that the enhanced
functionality of the router required java-script enabled
and I should either enable it in my browser or get a
browser that supported java-script. It also required
java-script enabled for the router setup and configuration
wouldn't work until I made a java-script exception for
the router's URL.

Which particular models are you using?

Django

PS: Rereading your post I noticed that you said the
routers didn't require java. The WGR614 didn't complain
about not having java enabled, it complained about not
having java-script enabled.
