That's what I have been arguing for. If they only have the ability to
configure their CPE with a web browser and they cannot ssh into an
openwrt command prompt and do anything with it, then IMHO they don't
have the need to go mucking about with a web interface that makes it
easy for them to shoot themselves in the foot.

You should look at dd-wrt also, the effort on it is quite different
than openwrt it's not just "another openwrt"

90% of more of people want to do the cheapest thing. If they can con
their ISP into fixing for free what they would normally have to pay
to have done, they will TRY that first.

I disagree this is what's going to happen. The larger ISP's around
here, at any rate, have figured this out and started to tightly define
what they will do. Sure, they add wifi into their CPEs. But, they
restrict their CPEs down so badly that you can't do anything interesting
with them. That's fine for Ma and Pa Kettle and that's what I think
they should be doing - as long as they leave a button that can be pushed
to turn everything off on the CPE so the customer can use their own
I do not see any real interest by any of the large ISPs in getting
further into the home. The reality is that by adding wifi they have
actually withdrawn somewhat from the home network. Now with wifi
they don't have to deal with ethernet chipset incompatibilities because
some customer found an old dumb ethernet hub in someone's garbage
and dragged it home expecting to use it.

Yes, probably because as time passes the young 10 year old grandsons are

Well that's the part that isn't easy to do. Particularly since
different problems can have identical symptoms. They may have slight
packet loss that doesn't impact anything other than DNS or other UDP
and makes sites far away very slow while sites within a few hops are

I think an area that can be improved greatly in CPEs is enhanced signal
reporting. You look at a typical cable modem CPE and it might show
signal to noise ratios on the cable but there's nothing in the interface
showing if the numbers are good or bad. Even putting a bar in there
that shows a continuum of red to green with the signal somewhere on that
would be helpful - as the customer can tell the tech support person
"My WAN signal levels are all showing red" and the frontline support
person can't then argue that's normal. After all, all WAN connectivity
does run on lower level something.
