Cable modem, on all the time?

by beatlejoel / November 27, 2004 11:05 AM PST

I have a cable modem and am curious about whether or not it is safe to leave it on, even when my computer is off. Is my computer still vulnerable when it is turned of if I am technically still online?
I am protected with virus scan and a firewall.
Thanks in advance,
Steve

You are Safe to leave your Cable Modem on all the time. If your computer is OFF there is little or no possible way for your security to be breached.

Can you talk on a phone if it's unplugged?
Can you watch TV if it's turned off?
Can you do anything on the PC if it's turned off?

You're safe.

A simple "your safe would have been sufficient". You could have done without the smart comments.

to be a smart comment. Just wanted you to think about it and used some comparisons and some logic. If a device is turned off it's not accessable. Be it a computer or any electronic device.

Sorry if you took it that way.

No problem, I understand. It is just that I am a little new to computers and am not 100% sure how they work. I just figured it is better to be safe than sorry and ask any question I might have, no matter what commom sense tells me.

Thanks for the info though!!!!

Ok. My opinion. It really depends what you mean by "safe". If you mean the safe as in "safe from hackers and spyware", well, yess, because your computer needs to be turned on to be able to access any files over the internet. The other thing I mean by safe is your modem. If you don't use it that much and/or only got it because it was cheaper than having 2 phone lines, I would turn it off if I were you. The reason for this is black-out's and lightning may "kill" your modem. This can realy only happen if your modem is turned on. Even if you have a power surger, I have one, and on 1 occasion it didn't work. It has probablt saved my modem a few times, but there is one time where it didn't. Just a hint. Also, If you don't plan to use it for a long time, I would turn it off and un-plug all the cords. I only reccomend this from past experience.

Your modem can be fried by a lightning strike even if it's turned off and unplugged. The lightning can come in through the tv cable. I had a tv get fried that way. It was unplugged from the wall outlet but still got hit through the cable.

If you have good antivirus software that you update on a regular basis and use a firewall (Windows XP, Service Pack 2 has a good built-in firewall) and you leave your computer on all the time, you still would be pretty safe. Keep in mind that if you turn your modem off all the time, then every time you turn it back on, it has to acquire the cable company signal each time and go through its startup sequence. I have a network setup in my house and I use a router to share my internet connection with two computers. My modem is on 24/7. No problems to date. Hope this helps.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
