Eli,
Is the linksys serving as DHCP server? Did you try
uninstalling/re-installing the ethernet adapter card? Have you tryed
connecting the failing PC to a different ethernet port on the linksys? Is the
ethernet cable that connects the PC to the linksys in good conditions? Have
you tryed using the cable the other computer has right now?

Hi Eli,
I would guess your configuration is something like this:
DSL modem-Linksys-2 PC
Am I right?
Are both PC connecting wirelessly to the linksys?

Hello:
I posted about this several days ago, but it seems the thread got lost.
Kindly excuse the repetition.
I had followed the troubleshooting steps on that Chicago Tech site as
recommened to me when I first posted here:
www.chicagotech.net/troubleshooting/noconnectivity.htm
.. [I'll summarize the steps taken below]
=================================
I use a LAN connection which consists of two PCs each connected to a
Linksys BEFSR 41 Router.
The Network Card on my PC is:
Model: Intel(R) PRO/1000 MT Network Connection -
Help and Support-->Tools-->My Computer Info-->Hardware shows the driver
for this to have been installed last December and to be supported.
" Model: Intel(R) PRO/1000 MT Network Connection - Packet Scheduler
Miniport
Driver: e1000325.sys
Friday, December 23, 2005
Supported "
I get frequent--almost daily--disconnects of my Verizon DSL connection
with a "Limited or no Connectivity" reading appended to a yellow
exclamation point on the system tray icon.
This happens only on my own PC and never on the other PC on the same LAN.
I can restore the connection only by unplugging both the modem and
router for about 30 sec and replugging them
When this happen,s there generally are DHCP warnings in my Event Viewer
with 1003 and 1007 event ID's. The 1007 Event ID's read in part:
===============================
"Your computer has automatically configured the IP address for the
Network Card with network address 0008742516DF. The IP address being
used is 169.254.245.117. "
"Explanation :
The DHCP Client service on your computer did not receive a response
from the DHCP server to the DHCP Discover message within the time
limit; therefore your computer's IP address was assumed to be invalid,
and the DHCP Client service generated another IP address."
===============================
That ISP beginning with 169.x.x.x yields a 'Limited or no Connectivity"
connection. At this point I need to unplug modem and router and replug
them as described above.
"Network Diagnostic Scan" run at Help and Support-->Tools----Network
Diagnostics generally show PASSED on all parameters. They seem quite
detailed. There is an occasional ping failure in these results, but it
inevitably resolves when I rerun the same Network Diagnostic scan a bit
later.
I looked into a possible WinSocket registry corruption, but the data I
gathered from advanced system info at Help and Support--->Detailed System
Info [Msinfo32.exe]-->System Summary-->Components--Network-->Protocol
seemed to rule that out as described in an MS KB article on Dx a WinSock
registry corruption. Futhermore, the Error readings are completely
diferent than depicted there for a winsock registry corruption.
My Windows XP Firewall is turned OFF , but the Windows Firewall/ICS
Service is on Automatic startup type as recently recommned on this
newsgroup.
So I have no idea as to why I'm getting those "Limited or no
Connectivity" disconnects only on my own PC and not on the other.
I use Zone Alarm Security Suite for both AntiVirus and Firewall
functions.
Any further suggstions on resolving this connectivity issue?
Thanks in advance:
-Eli
