>>The IP address being used is ************.
IF that IP address starts with 169.X.X.X  then you have automatically assigned IP address.

DHCP (Dynamic Host Configuration Protocol) Basics
http://support.microsoft.com/default.aspx?scid=kb;EN-US;169289

SUMMARY
Dynamic Host Configuration Protocol (DHCP) is a standard protocol defined by RFC 1541 (which is superseded by RFC 2131) that allows a server to dynamically distribute IP addressing and configuration information to clients. Normally the DHCP server provides the client with at least this basic information:
IP Address


Subnet Mask


Default Gateway
Other information can be provided as well, such as Domain Name Service (DNS) server addresses and Windows Internet Name Service (WINS) server addresses. The system administrator configures the DHCP server with the options that are parsed out to the client.

Hi DCLXVI!

I'm having trouble in understand - are you having random disconnections or you can't connect at all - If you can't connect at all, try to release/renrew your IP address:
GoTo start->Run->cmd-> in the Command prompt put: ipconfig /release
and then - ipconfig /renew
and check if you have a valid number with your ISP/Cable company.
If you can't renew your IP and have a DHCP error - you have a problem with the infrastructure. the DHCP server is the server that hands you your IP address and distrebute IP's to the clients in the network, so it's probably not a local problem.
You should also check if you have a dynamic (automatic) IP. GoTo Start->settings->Network Connections-> right-click Loca Area connection and choose properties. Double-Click TCP/IP and make sure it's on automatic IP (same thing for DNS server)

Good Luck
