I've been having problems with my wireless lenovo laptop Win Xp Pro Sp2,
all updates to date with Intel 3945abg wireless card and dhcp errors, and
having it drop the wireless connection
and not reconnect.
Your computer was not able to renew its address from the network (from the
DHCP Server) for the Network Card with network address 0018DE746057. The
following error occurred:
The operation was canceled by the user. . Your computer will continue to try
and obtain an address on its own from the network address (DHCP) server.
The semaphore timeout period has expired. . Your computer will continue to
try and obtain an address on its own from the network address (DHCP) server.
Your computer was unable to automatically configure the IP parameters for
the Network Card with the network address 0018DE746057. The following error
occurred during configuration: The DHCP client has obtained an IP address
that is already in use on the network. The local interface will be disabled
until the DHCP client can obtain a new address. .
In trying to figure out how to fix this (I'm assuming the router, a SMC
2804WBRP-G is configured correctly with WPA PSK, a long key and a 3600 sec
group rekeying interval)
The Intel drivers and Ibm Thinkvantage software has been configured and
reinstalled correctly per IBM/Lenovo.
I was researching KB893357 "The Wi-Fi Protected Access 2 (WPA2)/Wireless
Provisioning Services Information Element (WPS IE) update for Windows XP
with Service Pack 2 is available" which is installed on my machine,
and KB917021 "Description of the Wireless Client Update for Windows XP with
Service Pack 2", which is newer and contains newer dll's and replaces
I thought that applying KB917021 which is not pushed out throught the
Windows Update might help the dropped connection issues. However, when I
try to run KB917021, I get an error saying that it can't be applied because
of dependency conflicts.
I wonder if uninstalling KB893357 first, than installing KB917021 would
work. However, I'm not sure exactly what KB917021 helps me with.
Any Help would be appreciated
