While this is a popular factory default, it can be just about
anything. Let's not confuse the poster by assuming things -
let's get some facts first, then recommend a few tests that
are based on the results of these tests!

But if he DOES then see menu - it worked.

Hello,
Plenty of good suggestions.
Remove the router and the other computers and use a direct connection
from
the modem to the problem computer.

take care.

I was gonna suggest that but generally ( for Comcast near me anyways),
user needs to call ISP with MAC address for them to allow the hw onto
their network ( otherwise the hw seen as intruder).
 
I have four computers on a LAN but suddenly one will not go online.

I have turned every thing off, Modem, router, all four computers, for more
than ten minets. Then turn on the modem wait for all the lights to turn
green, then power on the router and wait for the green lights, then plug in
each cable one at a time and wait for the light to come on then the next
cable until all four are installed with lights on. Then turn on each
computer, making sure that it can go online before turning on the next one
and so on till all four are on.

I have tried changing to another port on the router with the computer that
won't go online. No Joy
Changed the NIC card to another PCI slot. Changed the NIC card for a known
working one. No Joy
Then swapped cables, still NO JOY!
What the Heck is it !?!
Also every time I did somthing, Windows still tells me it is connected.

Last night I saved what files I wanted, and wiped the hard drive clean, then
installed windows XP home edition, and It Still Does the Same Thing!!!

After reading all of that -to confirm: one pc doesn't work - period.
Anything happen on PC just prior to not working ?
When you display network properties,
NIC card shows enabled ?, firewalled ? etc

Click
Start- run -
type CMD , then hit enter
then type
ping 127.0.0.1

OK ?

type
ipconfig /all ( space between "g" and "/" )

Click in upper left of that window and choose
Edit - Select All
then
Same thing
Edit - now choose COPY.
reply to this message then click
PASTE
to show us the status.

During your testing did you ever try powering on only the affected computer
and see if it could then connect to the internet? If it works and now the
last one powered on can not connect it is time to check the range (number
of IP address) the router is presently configured to assign.

On one working and the affected computer try opening a Command window.
Start-Programs-Accessories-Command Prompt
Then issue the command ipconfig /all and see how they compare.
Do they both get assigned an IP address in the same subnet, DNS servers,
etc.?
 
Ok Bobb, 1. How would I reply to this message if the computer Will Not Go
Online?
2. I will try the ping and get back in a few.
3. I just did the 'ipconfig /all' and it came back with:
Windows IP Configuration:
Primary Dns Suffix= blank
Node Type= unknown
IP Routing Enabled=NO
WINS Proxy Enabled= NO
DNS Suffix Search list=domain
Now then the next part of the file lists the Ethernet Adapter, the correct
IP Address, Subnet Mask address, Physical Address, and Dhcp Enabled=yes
 
Yes I tried it as the first computer on the first port, where as it was on
the forth. Then tried it on all the ports, still no joy.
Yes the working computers come up with all the correct info and enabled
items 'Enabled'.
It did work last week but had been turned off for about four days, and this
all started when it was powered on yesterday morning.
 
Ok, I did the ping and it came back with this:
Pinging 127.0.0.1 with 32 bytes of data:
Reply from 127.0.0.1=bytes 32 time<1ms TTL =128> [this line was listed four
times]
Ping Statistics for 127.0.0.1
Packets sent=4
Received=4
Lost=0 <0% loss>
Aproximate round trip times in Milli-Seconds:
Minimum=0ms, Maximum=0ms, Average=0ms

I personally have no idea what this all means.

Replacing network adapters or reloading Windows is equivalent to
flailing your arms: Lots of energy spent but nothing gained. Lets
approach this in a systematic step-by-step manner. Take the following
steps on the problem PC and also on one that does work:
- Connect a USB flash disk to the PC.
- Click Start / Run.
- Type the three letters cmd in the box and click OK.
- Type these commands:
ipconfig /all > c:\%ComputerName%.txt {Enter}
copy c:\%ComputerName%.txt X:\
(Replace "X" with the correct flash disk drive letter)

When finished, connect the flash disk to your current PC.
Open the two files you created and paste them into your
reply. Mark each of them clearly so that we know which
one comes from the problem machine.
Launch "My Computer" and open the two
 
Sorry, not well off enough to own a USB Flash disk. But I will copy all info
by hand and post tomorrow, I am going to bed now, Good Night.
 
Where I live a 1 GByte flash disk costs around US$10.00.
A floppy disk would do too, or the chip of a digital camera.

re:

do you have nic icon in systray ? click on it - any network traffic ?
Does event log show anything ?

re: "the correct IP address" :
so as you change ports, the IP address changes ? ( just checking not fixed
and conflicting)
Plug this bad Pc into port one of router
open internet browser and type
192.168.1.1 hit 'enter'
Now see router menu ? prompt ?
Great - you're making it down the wire:not a hardware problem.and now can
see settings. That will vary by router.
Exit router power off
Unplug all other pc from router
off/on with just this pc - internet OK ?

See no menu ?
You say you wiped PC and problem follows PC.
Look at device manager any " !" 's on devices - or any 'OTHER" items
listed ?
IRQ conflicts ?
BIOS settings ?
==================
Compare bad PC info to one of your "good PC's".
I'll show you mine and explanations
==================

Do ipconfig /all " ( no quotes) on 2 of your PC's and compare good pc to
bad pc . You said you have router so all IP address should start with
192.168.x.y if you chose default. ( Note: I have things disabled I do
not need so if mine is different just note it in reply. Also your ISP may
vary but just compare your 2 pc's for differences). using Google to find
network troubleshooting tips, on good pc: compare to bad pc :

Good PC
start-run-cmd
type
Ping www.yahoo.com
note the address numbers returned
lets say numbers = 44.55.66.77 for now

now do it on bad pc
if it fails
now
ping 44.55.66.77.
If THAT works its a DNS issue , etc
.... go to next step in troubleshooting...

With my network "working"
here's what I see when I type
ipconfig /all:
========

Microsoft Windows XP [Version 5.1.2600]
(C) Copyright 1985-2001 Microsoft Corp.

C:\Documents and Settings\Bobb>ipconfig /all

Windows IP Configuration
Host Name . . : amd < My PC name
Primary Dns Suffix . :
Node Type . : Unknown
IP Routing Enabled. . : No
WINS Proxy Enabled. . : No
DNS Suffix Search List.: hsd1.comcast.net

**** THIS is the stuff that matters *****
with comments below after the " < "

Dhcp Enabled.: Yes < Router has a range of addresses and assigns until
all gone. PC uses "whatever address I'm given" . If not YES then YOU
assign a fixed address.

Autoconfiguration Enabled . . . . : Yes

IP Address. : 192.168.1.100
< Router has an address range and each port gets a number. The port I'm
plugged into right now is assigned .100
If you have a router it should start with 192.168. there are 2 parts -
one side is connected to internet and local side has no connection to
internet >

Subnet Mask : 255.255.255.0
<255 means "ignore" so only last group is what will vary >

Default Gateway : 192.168.1.1
<THIS is how MY router get to the network - VIA this router address this
is the part that will "forward your call to the internet">

DHCP Server : 192.168.1.1
< Router /server usually end in .1 and use the rest of the range to assign
address >

DNS Servers .: 68.87.71.226
68.87.73.242
Lease Obtained.. : Thursday, July 17, 2008
Lease Expires . : Saturday, July 19, 2008
<
These are the addresses assigned to the machines that will translate "
www.website.com " into 64.32.45.1 - the REAL address of " website" right
now.
DNS ? = Domain Name translating - server has a table where www.yahoo.com
gets turned into a number. There are only so many numbers in "a range"
and servers might change so as time goes by or servers come online /
offline, you will get a new lease >

Also lots of help sites out there - like

Plug this bad Pc into port one of router
open internet browser and type
192.168.1.1 hit 'enter'

Much better to find out the router's address first - the
working PCs will tell him what it is.
 
Ok, tried that once but the USB disk I got ($45 was the cheap one, AZ) would
only work with a 2.0 USB port, our computers are a bit older, and I don't
have a digital camera.
But did find the info that 'ipconfig /all' gave me was more than I can
understand, and will post it all some time today. The wife had to work a
second shift, she's a Nurse, so I get to watch the kids.
 
Tried that this morning but did the same thing, then tried all the others
after that and they work just fine, each and every one!!! This has gone from
frustrating to thinking about pulling the memory and hard drive out, then
taking it outside and killing it with a Very Large Hammer. But, I can't do
that, somebody would call the law and I would get in trouble for 'Disturbing
the Peace'. (But I Can Dream!!!)
 
Yes we had to do that when we first set it up March of last year (Qwest &
DTV) and was told we could have one to six computers on the same line with no
problems, and we have had no problems till now.
