Does anyone knows why this is happening?

Thanks in advance,

Is it just your home page? Is it permanent, or if you refresh will
the
page
come up? Have you tried accessing by IP address?

Hi Chuck,

This happened to me again tonight and I couldn't ping any web address.
I
had to restart to regain connectivity. I have 2 browsers and also AOL
but
I
wouldn't think that could be the problem. Do you think it could the
NIC?
It's updated. Any other suggestions?

newtechie

I'd start by finding out where you're losing connectivity, and is there
a
pattern? How is the computer connected to the Internet? What node in
the
connection could be bad - your computer, your router (you do have a
router,
right?), your ISP, the server that you're trying to access? When you
lose
connectivity, do you lose it for all websites? Do you lose it for
websites by
name, or by IP address too? What do you do to recover (or does the
problem go
away on its own)?

"Problems that go away on their own frequently return the same way".

Do some analysis - look for patterns.

Find out when, and where, the problem occurs.

Run a 4 part test, the next time you see the problem.

Hi Chuck,

I'm not sure I understand when you say were I'm losing connectivity. If
there's a pattern, I'm unsure but I do know that it happens at least once
a
day and not at the same time. I connect to the internet through a router.
In ipconfig it says node is Unknown. I have 3 computers networked through
the same router and they do not lose connectivity. When the computer that
loses connectivity tries to access any webpage I get a page can not be
displayed error. When I try to ping using web addresses it times out and
tell me I have no internet connection. To recover, I have to restart the
computer and all is fine.

So I'm baffled to as why this is happening. Do you think it's worth
adding
another NIC and disabling the onboard one to see if it happens?

The idea why you want to find out where you're losing connectivity is to
isolate
the problem. Now, IFF you have multiple computers AND only one computer
ever
shows this problem AND you know for a certainty that the one computer is
not
unique, simply by behaviour pattern, (have you tried doing the exact same
thing
from the problem computer and a non-problem computer, simultaneously?)
THEN you
have isolated the problem to the one computer.

The detail about 3 computers you just shared with us. Do you maybe have
any
more interesting secrets?

If the problem is unique to the one computer, by physical distinction (not
usage), then go and yes check the hardware. But before going after
internal
hardware (adding a NIC), check for easily diagnosed components like the
router
port and network cable. And firmware on the NIC and the router.

Hi Chuck,

Ok - it has happened again. Here are screen prints so you can see for
yourself what I'm talking about. The first pic shows that I was getting IP
info from ipconfig. The second pic shows I tried to ping my printer and
yahoo. com and it shows no connectivity.

newtechie

OK, the first pic showed that you had gotten IP address etc. I'm not sure of
the relevance when connectivity is lost - you don't lose ipconfig information
when that happens. The second shows that you lost connectivity with
www.yahoo.com - but from the above, you're suspecting the problem to be
connectivity with the router. Enough fooling around - get PingPlotter (free),
start it pinging, and look at the PP trace when the problem occurs. Run PP from
multiple computers for best results. Does your printer return pings normally?
