On site with a friend's company's systems.

Telecom guys run some updates, cut power to router, modem and assorted peripherals.

Power back on, phone works, but internet doesn't. Cable Co says internet is fine, must be a router issue.

I log into the router, which had the default password, find out it's statically set up. I bypass the router and instantly get an IP address i bring into the office.. Seeing as how static IPs are well, static. I figure they're not using a static IP. Set up the router to do so, now the PCs here can ping out by IP and browse by IP, but because the DNS is set up statically too, they can't get DNS. The PCs are also locked down. INdividually. So we get to figure out what each of the systems passwords are then tick the box, "Obtain DNS server address automatically."

*grumble*

..... but........ they had a static IP address set up... You sure the guy didn't fuck the gateway up and needs to be updated from the cable company again?

I ran into this same exact issue Thursday night. I had to reset my cable gateway, but that didn't automatically download our block of 5 public static ip addresses. Sure, I could get on with the dynamic one comcast gave me from the reset, but that's not the ip range we pay extra for. I had to call and have the block downloaded to the gateway again...

we download IP addresses now?

[cjkline83.livejournal.com]

Yes. The cable modem has to be provisioned to let the static IP addresses through. Otherwise, everyone would just be able to pick any IP address they want.

thanks. but that's not the point. It is the use of the word "downloading" I was pointing at. You don't download addres. You *obtain* them with whatever protocol is used (mostly DHCP or BOOTP, but can be PPP or whatever else).

[cjkline83.livejournal.com]

Really?

That's funny. Because without having Comcast "program" my gateway, which I assume means it had to DOWNLOAD some kind of data from Comcast in order to be programmed... I would not have been able to use our 5 static public IP addresses. These addresses are not DHCP or otherwise, they're static, always set, and unless the gatway is configured properly, there's no way in hell I would be able to use them.

Sorry for my loose use of Downloading, but when you think about it any type of communication can be termed as upload (speaking) or download (listening/receiving).

So, you just downloaded this conversation, which has most likely inflamed you enough to post another rebuttal, which I must also download.

Yes, I know. I'm stretching, and I'll stop now.

You are doing exactly what I see people in this community doing often: ranting about customers[1] that don't know how to express their needs, using imprecise if not totally wrong wording or phrasing to explain a problem. While non-technical users actually do have an excuse, the technical people don't.


[1] Yes I know it is the purpose of the community

So then, enlighten me.

When I reset the cable gateway, everything returned to defaults. I had assumed that the Static settings were automagically provisioned by the DOCSIS file the cable modem downloads when it connects. (Yes, this is correct, because I have hacked my cable modem before with a TFTP server. The modem downloads a config file).

However, this was not the case. Apparently comcast's ip blocks are programmed in some other way, the modem downloads another config file, and is rebooted. This is the exact process that the comcast tech and I went through at 10pm Thursday night.

That's all I know. I wasn't able to use our public static addresses until after the second program/download.

Where did I mis-speak and need to be corrected? I'm always open to learning new things.

and? At no point they talk about "downloading" addresses. See my other comment.

I hope it won't need reprovisioning, we called the cableco and they said the modem's fine, even had a tech out. So i'm hoping provisioning and modem's set up right. Plus they're paying bare minimum for service with no static ip on the bill

[cjkline83.livejournal.com]

Oh. Okay then. Just seems weird that they would have all the clients set with a DNS server that didn't work after rebooting the demark equipment. Did they change providers or something?

[taiki.livejournal.com]

Nope, same cableco. I'm guessing since the DNS was hardcoded on the PC, instead of using the DNS service on the router, which is a consumer grade WRT54G *grumble*, the guy who worked on this before is either really inept or out to bilk the guy for more work whenever something goes down.

[cjkline83.livejournal.com]

Well... we always set our client DNS servers to whatever ISP they are using, bypassing the Router for possibly faster resolution results. If they were working before the reboot, but didn't after it rebooted, that just seems very very weird. Nothing should have changed.

Unless he had the clients hardcoded to the router (192.168.1.1) and somehow the router changed its ip address (or was changed).

IDK. Everything is probably alright. This just caught me off guard because I spent 8 hours trying to figure out why everytime I plugged a Linksys ONE router (voip) into our comcast gateway it would crash everything (all clients, our sonicwall, and the gatway) and we'd loose internet access. Turns out I had to hard-reset the gatway, have comcast redownload the static ip's, and have them put the gateway in bridge mode. That was pure hell, but I had a primal scream of joy after getting everything working.

And a cry of "DEAR ****ING $DIETY, WHY!!!" with a rythmic thumping of head against the desk afterwards.

Guess where I used to work.

[cjkline83.livejournal.com]

Comcast?
Linksys?

[canray.livejournal.com]

Comcast, in their ONLY Home Networking department, trying to make those ****ing cheap-*** Gateway Modems work.

I still wake up crying every now and then, and remind myself that it's over now... It's all over.

It's that time when you know you got to get a new job, a better job, any job.

Wow. Dodgy modem? Call me an idiot if you like (I have been up waay too long and slightly drunk) but you should be able to define the difference between the IP assigned by the ISP and the internal LAN IP.

[taiki.livejournal.com]

Modem was FINE. It was giving out dynamic IPs... like it was supposed to. Guy who set it up set it up with a static IP.
