Windows 7: Network Places remembering old IP's?!?!?!? Driving me crazy

Network Places remembering old IP's?!?!?!? Driving me crazy

So, I have a class "A" IP Subnet in my home and a class "C" subnet. one is outside the "corporate" firewall and one is inside.

My Laptop wireless always loves to obtain the 10.0.0.1 which is the ISA router/firewall. Obviously there is an IP conflict here because the TMG/ISA server/GATEWAY already has that..

So.. Let me get a little deeper.

This only happens after a reboot and the IP settings that it "desires" are the following:

IP: 10.0.0.1
Subnet Mask: 255.255.255.0
Gateway: 192.168.1.1
DNS: 192.168.1.1

Now if anyone reading this thread knows... It should be....

IP: 10.0.0.101
Subnet Mask: 255.0.0.0
Gateway: 10.0.0.1
DNS: 10.0.0.4 = MY DNS
DNS: 10.0.0.5 = MY DNS

Should I delete the network controller, or do I have to delve into the registry to get this crap sorted out?

The Laptop ALWAYS connects to the N router but has a problem assigning the IP where it will just assign a bad IP or "first ip" in the sequence.

There are times that I need to get beyond the firewall, and I need to assign it a class "c" but I don't understand why this should be having a bearing upon future connections.

I have repeatedly reset the "arp" and DNS; to no avail.

I have typed this command at my last chance:
"netsh int ip reset c:\resetlog.txt"

If you can give me any other pointers, let me know.

Hi abuttino,

In addition to the great suggestion, you may use NetSetMan, you may create Profiles, Auto, Manual IP or have diff subnets.
