WARNING: ISP internet speed increase could lead to cable modem failures.

Hello,

I'd like to issue another warning:

When your ISP increases your internet speed, your very old cable modem may
fail eventually.

It's processor will have to work harder, draws more power, it may
fail/overheat or the adapter may fail.

Bye,
Skybuck.

You are a goddamned idiot.

They are made to operate FASTER than they get pumped by the ISPs.

They will NEVER get taxed to their max, and YOUR problem is YOUR
problem, not the hardware.

YOU cannot keep YOUR GRUBBY FINGERS OFF of the gear you toy with.

YOU are an abject IDIOT!

Yeah... asshole... YOU are worse than he is.

Adding groups to your post is proof of that.

How old is "very old" and what you expect to fail?

When an ISP increases the speed, they just add additional downstream
channels which are bonded together to form one data stream. For
example, in the SB6141, the 8 bonded channels are theoretically good
for 343.1 Mbit/sec download speed. However, only a few modern modems
can bond 8 channels. 4 or less is more common for "very old" modems
such as the SB6121. It is therefore unlikely that at ISP can add more
channels to a "very old" modem that doesn't allow for more channels,
and therefore unlikely that anything will overheat.

It's processor will have to work harder, draws more power, it may
fail/overheat or the adapter may fail.

Wrong. Take an AC power meter, such as a Kill-a-watt:
http://www.p3international.com/products/p4400.html
and insert it on the power cord of your cable modem. Try downloading
a big file at high speed and see if the current drain changes from
when the modem isn't moving any data. It will be roughly same power
drain, no matter what the modem is doing but will vary somewhat
depending on the number of channels being used for up/down load.
Typically, you'll be using 4 to 8 channels download, and 1 or 2
channels upload. These may vary depending on how your ISP setup their
system and if you have some kind of "burst" mode, where you get very
high speeds, but only for a few minutes, before you're slowed down to
"normal" speeds by dropping the added channel(s). For example, I've
measured the Motorola/Arris SB6141, which will draw between 7 and 9
watts depending on the number up/down stream channels are in use.

Bye,

One can only hope.

A larger pipe does not mean you get to push more water through a small
valve. The max speed will be the lesser of your ISP's supplied
bandwidth, the cable modem's speed, your router's speed, or your
computer(s) network bandwidth. You cannot get a higher bandwidth than
your slowest device.

Oops, sorry, I forgot to notice the nym of the poster. Never mind.
Time to update my filters.

Have you considered a bittorrent/utorrent scenerio ?

These kind of P2P are known to cause router crashes cause of high tcp
connection and/or udp ussage.

I would not be surprised if bittorrent creates a totally different picture
for you

Don't know about all that.

All I know is:

I like my current cable modem a lot.

And speed has been going up over the years.

So somehow the ISP _is_ increasing speed.

Ubee cable modem.

Skybuck.

A crash is because it is using code that is not well debugged. That is
nothing like burning out a CPU which seems to be what you are
describing. BTW, a CPU typically runs at full speed 100% of the time
unless it is designed to go into a low power mode which is normally only
used to conserve battery life, not to lower the risk of damaging the
CPU. Well, unless you have a 5 year old AMD x86 CPU. Those were hot
mothers.

Did you read his post? He is saying older cable modems are good for
150+ Mbps or some 20 MB/s. That's a lot of data. I know my provider
doesn't provide that sort of data rate no matter how much I pay.

No, I haven't because content has no effect on overheating. Well,
overly spicy movies do tend to get the viewer hot under the collar,
but I doubt they effect the modem temperature.

These kind of P2P are known to cause router crashes cause of high tcp
connection and/or udp ussage.

The common cable modem does not include a router. That's why it's
called a modem, not a router. Besides, crashed modems do not
overheat.

Ummm... could you decode that into something I can understand?

Bye,

Good night. 1AM here and time to crash.
