Keep loosing my static IP address

[Beerman]

I got a new Netgear 3700 router and I can't figure out why, each time I boot, I loose network connectivity. If I run a 'diagnose', it asks me to apply a fix and it then sets the next IP address. Example....I set it up for 192.168.1.113 and it wants to use .114. .113 works fine until I reboot and I get the same message. If I apply the fix, the very next boot, it wants to go to the next open IP address. I've confirmed that nothing is using this address.
This is on a wired network and 2 other boxes on this network don't have this problem. It's worked fine for years with my Linksys before it crapped out. I'm not sure if it's the router or another problem causing this.
One last thing, when I force the change to .113, it does work but only until the next reboot.
Thanks for any help you can give me.

Sounds like your static IP address is in the middle of the DHCP range that the router uses to issue out IP addresses. Have you configured your router to either not provide DHCP addresses, or shrunk the range so that your static IP addresses are outside of the DHCP range?

you should be able to give your computer a permanent (static) ip address so:



ignore the DNS server settings, and make sure the default gateway is your router.

I've set up the static exactly as your image and it's worked for years that way.

As far as the IP being in the middle of the range, no, it's not. It's very near the beginning. I can change it to be higher and see if that helps.

first--read the Router Manual to find out how to setup static IP addresses--then go to control panel 'Network and Sharing Center' to setup static IP (see attached) don't use the numbers in the photo-use the numbers from your router (make sure you select 'use the following IP address' radio button.

I've done what you show and my router is set for static IP addresses and other boxes set up the same way work just fine. But not this box.
I'm going to try using an address that's near the end of the address range and see if that makes any difference.

If you don't need static IP addresses, I'd just let the router assign the IPs. If you do need them, you can still let the router do all of the work - check to see if your router has static DHCP. Basically the router checks the MAC address of the computer attempting to connect, and it assigns the same IP address all the time.

Set your static IP to an address that is outside of the address rang your router gives out via DHCP. If its say 100 to 199 use 99 or lower.

I tried setting a static IP below 100 and it made no difference. After a reboot, I had no connectivity and I once again use 'diagnose' and applied the fix which then set the ip back to 113 where I wanted it. However, I"m sure if I reboot again, it will do the same thing and move the address to 114 and so on.
This is what diagnose said was the problem:

Static IP replaced with DHCP IP in Windows7

I faced similar problem when tried to assign static IP address which was falling in the range of IPs which were assigned by DHCP server. So, static IP was getting replaced with DHCP IP.

Run services.msc and disable DHCP and WinHTTP Web Proxy Auto-Discovery Services. Also stop both services.
Run msconfig.exe and disable DHCP from startup.

Reboot your computer. Ensure DHCP service is not running using services.msc

Now assign static IP and it should remain unchanged
