Re: Loss of Connectivity on Only One PC on a LAN ]UPDATE{

Hello:



I had posted about this towards the end of last month.  MVP Chuck had been
trying to help me through this. I'm updating the situation with some new
info, and. reposting it since that thread   goes back several weeks. My
apologies  if this isn't  the appropriate way to do this.



The original thread may be found at:



http://groups.google.com/group/microsoft.public.windowsxp.network_web/browse_thread/thread/6529be7c79cd41d2/#



To recap:



I have a LAN setup with only two PC's. The connection is via a Linksys
BEFSR41 Router.



My own PC occasionally loses connectivity~every one to three days. This is
noted by a yellow exclamation mark at the LAN icon in the System Tray,
telling me that my connection has limited or no connectivity. It is
generally preceded by some warning readings in the Event Viewer about
"Failure to renew address" on the network from the DHCP server. The other
PC, however-a Laptop-never  loses connectivity.



For a week, the connectivity problems on my end had stopped. When they
resumed last week, I no longer was able to regain the connection by simply
disconnecting my PC from the router-as was the case in my last post on this.
I had to shut the router down first.



After reading Chuck's blog on properly setting up a Network such as the one
we had intended:.



http://nitecruzr.blogspot.com/2005/05/using-network-setup-wizard-in-windows.html



I asked my roommate if she recalls how she had set up the Network Setup
Wizard in the first place.



She seemed to recall checking in the option:



·  This computer connects directly to the Internet. The other computers on
my network connect to the Internet through this computer.



Rather than the correct option:



This computer connects to the Internet through another computer on my
network or through a residential gateway.



Since we are using the Linksys Router for both our PC's the second option
would have been the correct one.



In addition to the connectivity shutdowns described earlier, I also notice
that I cannot find  locate her PC in My Network Places, nor can we ping one
another. This in itself   isn't a problem, since we don't share printers or
files. I mention it only insofar as it might   be symptomatic of the
underlying problem.



Question:



1)  Can she or I   simply rerun the Network Setup Wizard, and this time
check in the correct box?



Will this simply override any configuration errors she may have made in the
original     network setup?



Or is it necessary to change some settings and/or uninstall /reinstall some
hardware or software first?



2)  Since we both access the internet separately via the Linksys router,
should   I run the Network Setup Wizard as well? Do both users need to run
the Network Setup Wizard?





Thanks again for bearing with me on this:



-Eli

Hi Eli,

Your previous thread is still here, and I answered your post there.  I'll look
for your answers there too.
