Just sayin' that in every computer help thread on Mud, it's on average 9.3 posts until either:

a) The Mac folks show up proclaiming computing nirvana or
b) Nate shows up and fixes it...

Last night, I was posting something to 'Mud and the internet just disconnected.

I checked all the connections, did the ipconfig bullshit thing, even uninstalled/reinstalled the ethernet card (built into the motherboard). Nothing.

Did all the diagnostics, and the device is working properly.

So today, after trying every-freakin-thing else, I went and bought a stand-alone ethernet card. Installed it, it's sending/receiving data and all the diagnostics work, but it - and the original ethernet device - simply will not detect a DNS.

Tried removing the firewall - nothing. Tried system restore - nothing. Tried hard-boots - nothing.

Tried everything - nothing.

I know the network is fine - I'm on it now (on my laptop). It's the fucking desktop.

This thing has never worked right.

What chokes me is that I wasn't even doing anything weird - it simply stopped working in the middle of a 'net session.

Fuck. That is all.

Lol. Bush has been monitoring your posts and is out to get you. Bye bye IY.

Apparantly, you don't know how either.

[NaterGator]

IY;
This isn't going to make a whole ton of sense, but it's your problem so we've got to get to the root of it. There is something in your TCP/IP stack (it's like a stream of software that gets the data from your ethernet card to the operating system and proccesses it) that is not allowing DHCP to negotiate properly. In other words either your ethernet cards can't ask for an IP address, aren't asking correctly, or can't hear the response. Could be some firewall software went in and screwed with things automatically, could be something else entirely.

The next step is to see your TCP/IP settings. I need you to get screenshots of them.
Get to your ethernet card status that looks like this (sans the pink coloring):

Click properties. You'll see this:

Click the TCP/IPv4 item, then properties. You'll see this:

Take screenshots of both tabs, then go back to the general tab and click Advanced. You'll see this:


Take screenshots of each tab.

oh snap.

You spelled "apparently" wrong while illustrating my stupidity, by the way.

I know, right? We're so foolish for buying stuff that actually works...

[IronYuppy]

Okay, Nater.... (thanks for the help, BTW!)

Ok, those all look good, now how about the DNS?

EDIT: Also, on that screen that says "Limited or no connectivity" and "Speed: 100Mbps" ... does it say "Speed: 100Mbps" on your laptop as well?

[IronYuppy]

Oops...

[IronYuppy]

Yup. exactly.

[NaterGator]

Ok, on this screen:

Select "Use the following IP address:"
Put in:
IP address: 192.168.100.2
Subnet mask: 255.255.255.0
Default gateway: 192.168.100.1

Select "Use the following DNS server addresses:"
Put in:
Preferred DNS server: 208.67.222.222
Alternate DNS server: 208.67.220.220

Hit ok. Connect the cable. Open a browser window and try to visit the following address:
http://192.168.100.1/

If it works you should see the DOCSIS config/info page for your cable modem. If it doesn't I have a few more screenshots I want

Nope, nada.

The window with that address was just a blank screen.

I have to run out for a couple of hours.... I'll try back later. Thanks again for the help. D'oh. Stupid technology.

[NaterGator]

Ok, sorry for not having a quicker/better solution. We'll keep pluggin away though, there is probably a solution right under our noses

#26 shows that as a 10/100 card.

The yellow ! symbols means wrong drivers a lot of times. Even though it says its functioning correctly, its really not.

IY, did you try to ping the dhcp server? #30.

Are familiar with Device Manager?

A very tiny shark with wires coming out of it that you put inside a matchbox car that you push/"drive" with your thumb.
Duh.


Wireshark rules BTW.

That's not the one with the laser on it's head, is it? Because while that sounds useful for some stuff, it won't GET ME ON THE MOTHERFUCKING INTERNET.

not to butt in here... just skimmed over all the posts

if you havent updated the motorola firmware you should, it may have issues with some network cards

are you running mcafee on the system? bad bad bad'

updated network drivers? windows up to date?

does it have the same problem if you boot up the pc in "safe mode with networking" ?

using the same network cable on the laptop then the desktop?

I love fixing this kinda stuff and do it for a living, ibut im still at work right now so I'll try to help

Nope, not sure how to do that.

Nope. Norton A/V.

updated network drivers? windows up to date?



Yes. Yes.

does it have the same problem if you boot up the pc in "safe mode with networking" ?




Haven't tried that yet...

using the same network cable on the laptop then the desktop?



Yes. Cable is fine. Modem is fine with the laptop.

I love fixing this kinda stuff and do it for a living, ibut im still at work right now so I'll try to help

Thanks!

i dont know what model modem your running, but you might try seareching for it + firmware update on motorola or comcast site, it should include instructions on how to install

Before doing much to your computer you should have a backup of all important data on it

also spyware and other annoying junk can cause issues like your having

to boot into safe mode with networking restart your computer, then after it gets past its initial logo screen and before it gets to the loading windows screen (usually right after a beep) hit the F8 key a few times, then select safe mode with networking, if your able to connect and surf consistently then it is most likely a software issue on your pc

go to spywareguide.com and click tools, free online scanner, then follow the directions, or click here http://www.xblock.com/download/xclean_micro.exe and choose open or run

run it in safe mode and in normal windows after you restart

if it finds anything choose remove it then go to download.com search for and download spybot, install it, run updates, (uncheck teatimer during setup) and run spybot, takes a while though

also try this little program LSP-Fix - a free program to repair damaged Winsock 2 stacks it can fix connection issues caused by spyware etc.

I gotta get back to work for a while, but if your still having trouble this weekend I will send you some step by step stuff to check, shoot me an email if you need nd4spd296@yahoo.com

Your cable modem firmware is almost never upgradable. You can call your cable co and see if you can get an upper tier tech to push you a new firmware, but good fawking luck.

This issue isn't firmware though since the cable modem worked prior on the same machine.


IY, reset those settings back to the defaults (what they look like in the pics before I had you change them). If you have a thumbdrive (you must to move the screenshots?) move wireshark onto your desktop and install it.
SourceForge.net: Downloading ...

Start listening on your network adapter (whichever one you are using, I'd take the new one out and use the orig since it's not the problem and used to work). Plug the cable in and log the traffic. Stop the monitoring after like 30 seconds and take a screenshot.

Actually, I'm just going to mash the keyboard and hope that what he said makes sense somehow.

Nate's steering you right and knows much more about networking then I do.
WireShark is a network protocol analyzer that "watches" EVERYTHING your network does. Packets being sent to and from machines. We wanna see where/if the packages are going from your troubled desktop to the router and some other info.
Wireshark: Go deep.
Great tool to troubleshoot networks. Download it on your laptop, transfer it on a USB thumbrive or CD to your troubled desktop, run it, and bring back some screenshots to your working laptop.

Too many cooks in the kitchen...I'm just watchin' from the sideline.
