Why do I have to powercycle my modem all the time?

I'm curious about something: it seems like a couple of times a week, I try to log on to the internet, and I can't get online. I call Charter tech support, and they have me unplug my cable modem for about a minute while my PC restarts,and then I'm able to get back online again. Sometimes that won't work, and they then have me go into winipcfg(I use Windows 98) and release and renew the IP address after restarting the modem, and I'm get back online again. I've taken to doing this myself without calling them, since I've been through it so many times.

Why is it that this happens to me? I have a friend who gets broadband service from another ISP in Louisville, KY, and he never has to restart his modem like this. He was telling me though, that it might have something to do with the age of the wiring on the power grid around here, and voltage spikes throwing everything out of whack. Can anybody offer any input on this?

Are you running a firewall like Zone Alarm?

What type of modem do you have?

I get the same problem with this SA modem they sent me. Kind of pain but at least I get the speed that I am paying for which is more than some who post here.

Some modems are picky on signal level, the surfboard is the best I believe (correct me stan999 if needed).
If you have fluxuating signal levels that could be it. Or if they are doing work and require alot of 'resets', that can do it too.

The other things (looks like win98 related), is if you have a firewall (like stan suggested), you need to set it for DHCP to allow communication between the DHCP server and your computer.

The other is system standby. When your computer goes into standby or hibernation, it stops most all functions of the OS, including DHCP/communicating with the internet.
Turn that off, and just have it to shut off monitor after a few. If that works, that was it .

Fill us in on what you find.

The question is, when you lose connectivity are your lights blinking...do they look like they always do?
Sometimes rebooting the computer doesnt help and you have to release and renew manually.
Another possibility, known Win98 issue:

SYMPTOMS
Windows 95 or Windows 98-based computers using Dynamic Host Configuration Protocol (DHCP) may occasionally fail to lease an Internet Protocol (IP) address when the network or DHCP server is very busy.

No firewall, direct connection between the modem and PC. Modem lights are fine at the time I try to connect. So, I'm thinking we can look at this from the power fluctuation angle?

Oh, yeah..........and I shut my PC down every night before I go to bed.

BigBearTech said: "Or if they are doing work and require alot of 'resets', that can do it too."

Exactly what are you referring to when you say "resets?" And what kind of work could be creating this?

Sorry for all the questions, but I'd just like to understand the process a little better.

Like rebooting the DHCP server. I cant think of anything else that could do it, but Im sure there are. Maybe the Node, but I think you would see something on your side.

If all the lights are working, then it could be a signal issue. That definatly requires a call in to get a tech out and check your signal levels.

Go to »192.168.100.1 and paste both the signal page and logs here. May be something there.

Are you using a USB connection or a NIC?

Signal levels(done with 3 refreshes, like a Charter tech advised me to do on the phone once):

Signal to Noise Ratio: 36db
Downstream Power: -1dbmv
Upstream Power: 41dbmv

Network Access Control Object(the Charter phone tech told me that it should always be on): On

And I'm using a NIC.

I went to the logs page, and there didn't appear to be any warnings or anything that said Failed, or anything like that.

Thanks for all the response, by the way!!!!

When I restart the modem the wan side does not blink, the PC and status lights are fine. I simply keep restarting until the wan light blinks, then I know its passing traffic. Almost like charters router is a little slow to renew my ip.

Have you ever run Zone Alarm as a firewall on that machine?
Have you run Adaware or Spybot to look and see that no spyware programs exist on your machine? Spyware can sometimes hose up your connection, and Zonealarm leaves behind a few settings in the registry that you have to remove.

If you just do a Release/Renew and not power cycle the modem does that work?

If you go to winipcfg and click the "More Info" button how long is your lease?

bigbeartech said: "If you have fluxuating signal levels that could be it," in response to my initial question about why I have to powercycle a modem to re-establish my connection once a week.

I just want to make sure I understand this correctly - can the signal on the cable modem line dropping out make Windows think it's not reading the IP address right that it got from the DHCP server before the dropout? Is that what's happening?
