cable right from their modem.

At work, we have a MonkeyBrains dish. We pay for 50+50 and get
500+500.

This seems to be a trend, much faster internet than we signed up for,
same price. The backbone fibers must be moving petabits.

A lot of those multi-hundred megabit connections will go to a wireless
router where all user devices are connected to it via 802.11n or
802.11ac in a super-cluttered RF environment, and topping out at 50 or
100 megabits throughput on a good day

20 mbit is good enough for most things. I bought a cheap router last
time, waiting for it to be inadequate and that day never came.

Maybe you signed up for megabytes and you\'re measuring megabits ? 8 data
1 start 1 stop ?

All megabits. And it\'s not an RS-232 interface.

I don\'t know how cable modems work. Some complex constellation
modulation I suppose. Maybe some 8b10b in there somewhere.

It\'s QAM. 256QAM, 64, whatever.

However since I now have a fibre connection I don\'t care. The failing
junction box (think black plastic policeman\'s helmet with multicoloured wire
knitting and joints inside) is buried in the verge in front of my house. If
the water table rises it floods and shorts out circuits. When the guys come
to sort it out it sounds like maracas when they shake it!

In theory I think it is supposed to be water tight but in practice rodents do
for the catches or seals and after a few years it isn\'t.

Strange; we found containers ( not sheet metal, something thicker - called \'em
Bud boxes ) with O-ring seals and sealed connectors for  a pretty reasonable
price retail years ago. Like tens of dollars.

They seem rat-proof to me.

I don\'t think the problem is \"equipment\" as much as it is \"personnel\".
Here, much of the line maintenance is subbed out; how much do you
think the sub worries about the kit they\'re servicing?

The pedestal nearest my house has a 1.5\" gap between front cover
and back assembly. Large tye-wraps hold the front to the back.
Critters, weather, who-knows-what-else free to wander inside
and have a look/nibble around...

This \"fix\", apparently easier than scraping a bit of soil out from
the front of the pedestal so the cover can fit up against the back
at its original placement (which is now 0.25\" below grade and thus
impossible to mate WITHOUT removing a shot-glass full of soil!).

The uncontrollable part of the equation is the performance of
the server and all the fabric between hither and yon.

If you\'re *watching* live content, then the bandwidth of the
content sets your required minimum throughput (cuz you can\'t
WATCH it at anything faster than real-time).

And, if you\'re not sitting and watching, then who cares how long it
takes to get there -- as long as it does so intact?

[Hence the beauty of torrents and site scrapers... just let the
machine do its thing at whatever speed the fabric will *allow*
and check up on it from time to time. Who wants to watch water boil?]

ADSL links used to die at least every couple of months with router

realtime. I always got a few of those per day in normal operation.

Our Comcast box downloads its software from the mother ship, every
time it powers up. That takes about 15 minutes. I asssme they are in
the usual constant-upgrade bug manufacturing mode, as downloaded
software usually is.

Ouch! That is a royal PITA. Mine has to have its firmware updated every
now and then if a vulnerability is found and/or exploited but it boots
in under a minute from whatever internal SSD/memory stick it has.

It issues dire warnings about not switching it off during an update.

If it\'s easy to fix, it\'s easy to break.

Too true

Yes.

I also have Comcast Internet service, but I own the cable modem (an
Arris SURFboard SB6183, and so I don\'t get the 15-minute delays, or a
host of other fiddles.

I may upgrade the cable modem to get access to the free phone service
(and phone number that comes with that service.

I have Comcast cable plus the \"free\" phone thing. Modem reboots are
fast. It\'s the fancy cable TV box that has the slow reboot.

I disconnected the phones because all the calls are spam.

Well, we still get valid phone calls, so everything that we don\'t
recognize goes straight to the answering machine. Most of the spam
leaves no message.

Sometimes I do answer a suspected spam call, but don\'t say hello or
anything, just listen. If there is no sound coming from the caller,
it\'s likely a robot mass dialer that switches a \"salesman\" in only if
it hears a response such as hello.

Sometimes I do get what seems to be a person, but are not - the tell
is that there is zero response to anything I say. It\'s basically a
taped message. I\'ve met human salesdroids like that. Just hang up.
