Windows 7: Default gateway changes after reboot

Default gateway changes after reboot

I am having problems with my internet connection. I am running a pc behind a router with DHCP enabled.

Often when I restart the computer the computers internal IP is also set as the default gateway.

My router is 192.168.1.1

My computer gets automatically IP 192.168.1.4
and then gets Default gateway of 192.168.1.4

Then I have to manually set the default gateway to 192.168.1.1 for it to work. But next time I use the computer the gateway has changed again and I have to change back.

What to do? I have the latest network drivers for my nvidia mobo and running windows 7.

The name of the network I am connected to also changes a lot.

Ok a few questions.
1) does the router have the newest firmware?
2) can you fill out your system specs in userCP?
3) what anitvirus/firewall are you using?
4) is this a wired network or wireless?

1. Yes, upgraded two days ago.
2. Filled in most of them now.
3. Avast Antivirus and windows firewall.
4. Wired network (wireless turned off) on a Netgear router.

Just for fun try setting the the ip and gateway to a static address and reboot if it keeps working use that.
