A neighbor has Cox Communications high-speed Internet. The modem is a SA DPC2100R2 (mftd. last year) and the router is a Linksys WRT54G. I can easily run a ping test and speakeasy (the packet test is zero and the downstream/upstream speeds are all good numbers).
However, I can't successfully engage the website at:
to run a cable modem signal strength test. All I get is a blank screen with "done" at the bottom left, i.e., I don't see the "Login" banner to get me to the signal strength page.
Incidentally, the neighbor's web browser is Mozilla -- if that matters.
What am I doing wrong? Is there another website to test cable modem signal strength instead of the one listed above?
