Big problems with LAN connection to router.

[Guest]

I have been having some problems connecting to my ADSL Router

Started off randomly disconnecting then reconnecting every morning. Tried to
do various things to fix it. These included trying to reset TCP/IP settings,
and winsock settings. I tried deleting the winsock and winsock2 keys from
registry and restarting. I have tried the same with Tcpip\parameters and
DHCP\parameters.

Through trying to fix my LAN connection now has no IP address and gives
error saying failed to query tcp/ip settings of the connection when repair is
attempted.

ipconfig gives error saying it is unable to query host name.

i have followed process to reinstall TCP/IP settings through network
connection properties, but has had no effect.

MSinfo32 shows that winsock may be corrupted. (As explained by KB article) I
have tried netsh winsock reset. I still only get a couple of headings in the
network. RSVP UDP Service Provider and RSVP TCP Service Provider.

Netdiag can not find TCP/IP Information from the registry.

I can not connect to the internet via a dial-up connection either. Or
connect with a wireless card to my router.

I have not been successful in running System Restore to fix the issue.

I have now uninstalled Norton Internet Security and System Works 2006.

I am running Windows XP SP2 with full updates. Computer is Dell Dimension
8400, Intel P4 3.2Ghz. 1.5GB RAM. NIC is Broadcomm NetXtreme 57xx Gigabit
Controller. The NIC is integrated so cannot be removed.

I have tried unplugging and replugging cables and also tried 2 different
cables

My manufacturer was of no hope.

My next solution will be a reformatting and reinstallation of Windows but i
would like to avoid if possible.

Any help would be great.

Do i need to give any more info?

In addidtion, DHCP Registry entries seem to be corrupted and missing.

My router is a NetComm NB5580W

Ross,

If you had the computer randomly disconnecting then reconnecting every morning,
it's hard to see that as an LSP / Winsock corruption problem. LSP / Winsock
problems generally don't come and go, on their own. Not as a total disconnect /
reconnect anyway.

So what is the status right now? Can you connect at all? If not, let's see if
we can get you at least back to where you were. The registry based repair from
Bob Cerelli should be a good start. That's step 8 in my article.

Please give that a go, and see if you can get reconnected. If doing that
produces no results, then:
1) Un install drivers for the integrated NIC.
2) Reboot.
3) Reset TCP/IP, then rerun the Cerelli LSP / Winsock repair.
4) Re install the NIC drivers, if not forced by the reboot.

We gotta work on the random morning disconnect / reconnect next. Be patient
here. If it's reconnecting on its own, then you have 2 possibilities:
1) Hardware.
2) Malware.
Both will demand their own diagnostic procedures. But work on the above first.
