Office IP / Home IP conflict

[PacMan]

Our company is on a 10.x.x.x network.

A user brings her laptop to the office. Connects and pulls the 10.x.x.x network. Unplugs her laptop and goes to another location. Then she pulls home network of 192.168.0.x and its from a Netgear (DNS Suffix). I checked the port and it is connected to our network in the network room to our cisco switches. I released and renewed and it picked up the 10.x.x.x network again. I can’t figure out why it did that. She does not have internet at home. She does have an Air card. Could that have put the info in? But why netgrear DNS Siffix?

Looks like you have a wireless router in your network. That unless the NIC has a secondary IP set.

How do I clear the Secondary IP set on my NIC? I just found that I imaged it on a netgear router... so from the switch to the patch panel, then to the wall in my cube and then a netgear router to image it. I'll go into 192.168.0.1 and see if I can configure it.. Any thoughts?

How do I clear the Secondary IP set on my NIC??

In the TCP/IP configuration - alternate configuration (of course it depends on OS)
But first get rid of the DHCP on the rogue router. If anything connect it using the LAN interface (NOT WAN) to your network and use it as a simple wireless access point.
