Random "A network cable is unplugged" Errors

Configuration: Pentium III 600Mhz, 384MB RAM, WindowsXP Pro, IE 6, Belkin
F5D7230-4 Wireless/Cable Gateway Router, and DSL. This machine is plugged
into (via cable) the router. There is a laptop that operates on the
wireless side that does not have this problem. These machines and network
were operating flawlessly since installation of the network which was about
3 months before the problem appeared.

Error message "A network cable is unplugged" appears on an intermittent
basis.

The network does becomes unavailable while this error is present.
When the error dissapears the network is usually available to Outlook and
IE.

I say "usually" because sometimes the behavior is such that it rapidly
bounces back and forth between the two messages above and there is no time
for anything to re-establish connectivity with internet sites.

There is a workaround that sometimes corrects the problem. I go to "LAN
Connection 3" Properties - Configure - Advanced - LinkSpeed/Duplex Mode and
select "10 Half Mode". Sometimes this requires a reboot of the system to
take effect. Sometimes a reboot of the system itself will correct the
problem. However, both "fixes" are temporary and last anywhere from a few
minutes to several days.

When in the "A network cable is unplugged" state, if a "Repair" (rightclick
the network icon and leftclick "Repair") is attempted, it will pause for
some time then come back with an error message with words to the efffect
that it was unable to obtain an IP address and to contact the LAN
administrator.

What seems so strange to me is that the laptop on the wireless connection is
completely oblivious to this. I've replaced the "cable" in question.

Though extremely annoying this is not a show stopper. If I have to I can
revert
back to dial-up to get mail. But the lady of the house has no patience for
this
kind of nonsense and well...

Any ideas? Anyone?

Thanks,

Dave M.

Here's an exampler of the error I get when reading this news group and the
"A network cable is unplugged." error appears.

"Header download for the 'microsoft.public.windowsxp.network_web' folder did
not complete. Account: 'msnews.microsoft.com', Server:
'msnews.microsoft.com', Protocol: NNTP, Port: 119, Secure(SSL): No, Socket
Error: 10060, Error Number: 0x800CCC0E"

If I do nothing and retry a download after the error dissapears on its own
accord, all works OK.

Bad power can sometimes do this by transiently upsetting a switch or
router - it appears that these can be very sensitive to relatively
minor power line glitches. I have a home network with up to five
systems ("up to" because it depends on whether my sons are home from
College) on a Belkin 8-port switch. Our local power does have
intermittent problems (mainly brownouts). I have my system and the
switch in my office on a UPS. Despite this, when there is a power
problem and the UPS takes over, the lights on the switch flicker and
the "Network Cable is unplugged" error appears and disappears.
Everything else on the UPS chugs along happily.

Peter,

Your experience, coupled with another tip in a MS knowledge base piece
recommended by an MVP in this group, (configure to allow PC take control of
power to the ethernet adaptor/NIC) is starting to narrow in on what my
problem appears to be. There is this vague recollection that I reconfigured
something in the plugging arrangements in the powerstrip that supplies the
PC, router, modem, etc. about the time this problem started showing up.

Thanks for your observations.

Regards,

Dave M.

Hi Guys,
I have had the exact same problem with the "network cable unplugged"
message and "Network now connected" message bouncing rapidly back and
forth every ten minutes or so.
Luckily, this happened since I installed an AC line stabiliser to plug
the PC and peripherals into........great stabilisation, huh? I assume
that there is some kind of power fluctuation going on when the
stabiliser kicks in? This is not really my area. When I saw in the
first post that the laptop is not affected I immediately thought that
maybe it is not connected to the same power source.

So how can I protect my system here in Brazil - where the power grid
is extremely unstable? Or is it OK for the unplug/replug scenario to
be happening?
I don´t actually lose my connection when this happens......sometimes
it happens in the middle of a download and I do not detect any change.

Best wishes,
Briggy

Hello Briggy,

I tried to solve the problem by installing a battery-backup / power
conditioner and it had no effect.

My problem turned out to be the NIC / ethernet adaptor card. When I
replaced that, the problem went away.

When I got the "network cable unplugged" error my connection to the internet
was indeed dropped. Sometimes it came back quick enough so that whatever
was in progress continued on without ill effect. Other times the "page not
found" error would appear or Outlook would complain that the server was not
available.

FWIW

Hi Dave,

Well I guess at least you got the problem sorted out in the end.
These things are a pain when they happen - because the first place
people tend to think is that it is a software config problem - then to
the hardware later ( after hours of trawling about)! Mind you ,
considering all of the possible ins and outs and quirks of operating
systems like Windows/Mac, don´t know LInux - haven´t made the leap
yet....I suppose I should not be surprised that software is the first
place to look!! LOL

There is a workaround that sometimes corrects the problem. I go to
"LAN

Mode
and

take effect. Sometimes a reboot of the system itself will correct
the
problem. However, both "fixes" are temporary and last anywhere from
a
few
minutes to several days.

When in the "A network cable is unplugged" state, if a "Repair"
(rightclick
the network icon and leftclick "Repair") is attempted, it will pause
for
some time then come back with an error message with words to the
efffect
that it was unable to obtain an IP address and to contact the LAN
administrator.

What seems so strange to me is that the laptop on the wireless
connection
is
completely oblivious to this. I've replaced the "cable" in question.

Though extremely annoying this is not a show stopper. If I have to I
can
revert
back to dial-up to get mail. But the lady of the house has no
patience
for
this
kind of nonsense and well...

Any ideas? Anyone?

Hi Dave,

Well I guess at least you got the problem sorted out in the end.
These things are a pain when they happen - because the first place
people tend to think is that it is a software config problem - then to
the hardware later ( after hours of trawling about)! Mind you ,
considering all of the possible ins and outs and quirks of operating
systems like Windows/Mac, don´t know LInux - haven´t made the leap
yet....I suppose I should not be surprised that software is the first
place to look!! LOL

Hello Briggy,

I tried to solve the problem by installing a battery-backup / power
conditioner and it had no effect.

My problem turned out to be the NIC / ethernet adaptor card. When I
replaced that, the problem went away.

When I got the "network cable unplugged" error my connection to the internet
was indeed dropped. Sometimes it came back quick enough so that whatever
was in progress continued on without ill effect. Other times the "page not
found" error would appear or Outlook would complain that the server was not
available.

FWIW

Hi Guys,
I have had the exact same problem with the "network cable unplugged"
message and "Network now connected" message bouncing rapidly back and
forth every ten minutes or so.
Luckily, this happened since I installed an AC line stabiliser to plug
the PC and peripherals into........great stabilisation, huh? I assume
that there is some kind of power fluctuation going on when the
stabiliser kicks in? This is not really my area. When I saw in the
first post that the laptop is not affected I immediately thought that
maybe it is not connected to the same power source.

So how can I protect my system here in Brazil - where the power grid
is extremely unstable? Or is it OK for the unplug/replug scenario to
be happening?
I don´t actually lose my connection when this happens......sometimes
it happens in the middle of a download and I do not detect any change.

Best wishes,

Peter,

Your experience, coupled with another tip in a MS knowledge base piece
recommended by an MVP in this group, (configure to allow PC take control
of
power to the ethernet adaptor/NIC) is starting to narrow in on what my
problem appears to be. There is this vague recollection that I
reconfigured
something in the plugging arrangements in the powerstrip that supplies
the
PC, router, modem, etc. about the time this problem started showing up.

Thanks for your observations.

Regards,

Dave M.

Bad power can sometimes do this by transiently upsetting a switch or

minor power line glitches. I have a home network with up to five
systems ("up to" because it depends on whether my sons are home from
College) on a Belkin 8-port switch. Our local power does have
intermittent problems (mainly brownouts). I have my system and the
switch in my office on a UPS. Despite this, when there is a power
problem and the UPS takes over, the lights on the switch flicker and
the "Network Cable is unplugged" error appears and disappears.
Everything else on the UPS chugs along happily.
