Does the cable company have control over modeoms?

This is kind of strange. I had been having a lot of problems with my cable interent. The interent would cut in and out frequently drivng me up the wall. Well I finally got pissed enough and we called them. Of course they called up the modeom on their machine and it said it had had no problems for like 26 days or something. Well soon after saying that (internet not working when called them) the modeom reset (does that when it regains signal) and starting working again. And its been perfect ever since! Im wondering what did they do and was it on purpose to get away with a little bit less bandwidth at times or what? 😕
 
When you plug in your cable modem, it downloads a configuration file from your ISP that dictates your bandwidth caps. If they want to change your bandwidth caps, they have to build and set a new configuration file for the modem to download and send the reboot signal to it.

I see. well thats nice to know. im wondering that since they upgraded their lines not long ago and our speeds are a bit funky if it was confusing it and making it go out

It's possible. What kind of "upgrades" were done to your lines? If you think you have a speed problem call your ISP and ask what they consider to be a speed issue (slow speeds, etc). Try running a continuous ping to your default gateway for a few minutes to see if you drop any packets. Any packetloss to your default gateway whatsoever is a problem. That could be it, but that's just a symptom of the real problem which could be cracked (old) insulation on the coax or improper power levels through it, requiring a repeater or filter.

I'm sure you were kind enough to also point out that would probably get you banned from cable for life if they ever found out.

😕 WTF are you talking about?

Most modern modems will power cycle themselves atleast every half hour if they aren't passing traffic through coax to something that's replying to them. If there's no connection being made at all, the cable company can't do anything remotely ... because that requires a connection. 😛

It's possible that your modem wasn't properly provisioned on their side and they just set a few pieces of data into the provisioning table... or upgraded the firmware. 😉

bascially they upped it to 3meg service and we didnt upgrade 😛

and I think our speed is alright. my comps a bit slow so I dunno for sure.

but I also ahve no idea what your talking about with the pinging to the gateway cause I dont know what the gateway is 🙁

heh i think you are just a little bit confused. NIK is not telling him to undo the caps wich would get him banned for life.

he is explaining what cable modems do. heh

Read it as telling him to uncap his modem. My reading comprehension skills suck 😛

My bad 🙂

Are you a Comcast customer?

Your default gateway is part of the connection information for the TCP/IP suite. More specifically, you can find what your gateway's IP is by looking at your computer's IP info.

To find your computer's IP:
Win9x: Start > Run > winipcfg
Win2k/XP: Start > Run > cmd > ipconfig -all

Hacking your cable modem can be a real bitch... if you don't know what you're doing.

:evil: 😀 😉
 
I used to have a problem with my comcast service using an RCA modem where use of the television in close proximity would hump the connection. Apparently, the older models weren't shielded properly. They came and replaced it with a newer modem, which I think is a Motorola, but now the internet cuts out for a few seconds every few minutes and is driving me batty.
 
im not sure why i would ping my LAN ip. 192.168.1.1. I did that anyway 😛 and I would occansionally drop a packet due to request time out.

ping (gatewayIP) -t

wait 1 minute

<ctrl> C

Call comcast's customer service and report periodic service disruption. Tell them that you're dropping packets to your gateway and remind them that your modem was recently replaced.

something is very wrong if you're dropping packets on a LAN.

Heh... you're on a home network. Screw that. Charter won't help or care if you're pinging your router. Plug directly into the modem. Power cycle the modem for 10 seconds or so, then reboot your PC if you don't know how to release/renew your IP.

THEN check your IP settings and run a continuous ping to your gateway.

If you're dropping packets on your home network (by pinging the router), then you either need to replace the NIC or reinstall your NIC, Client for MS Networks, and TCP/IP which are done different ways depending on what OS you're on. If that doesn't work, you have either a loose connection physically or a bad port on your router -possibly a bad router alltogether.

I'll try it when I got home since I can't SSH in from work because the whole thing appears to be down now. And calling Comcast's tech support is only slightly more enticing than eating cakes of ground teeth. 🙁
