I am having problems with a PC which loses its IP settings once or more a day. It's connected to my router by ethernet. When this happens:
At boot up, the IP address is 192.168.0.207 (The IP addresses should be in the range 192.168.1.x)
Hovering over Network connection icon, it says "Access: local only"
I can't get on the internet
If I run Windows Network Diagnostics, they say: “The IP settings on this computer are not valid”. Choosing option 1. "Automatically get new IP settings for the adapter “Local Area Connection” generally does the trick.
I never used to get this problem. Though I first noticed it when trying to switch to a new Wi-Fi router, it's persisted when I went back to my previous one.
Can anyone suggest what's wrong, plus a more permanent solution than doing this bodge every day?
Windows Vista, latest SP
Belkin Wireless G plus MIMO router Have had the same problem with a TP-Link TL-WR741ND
Cable modem is a Motorola Surfboard SB4100
Other laptops seem to be able to connect wirelessly to the internet during the times my direct ethernet connection is failing, so I wondered if the problem is more with the PC connected by ethernet cable.
When working correctly, the readings from my router are:

Ok, see below.
I noticed that DHCP is set in both the Belkin router and the Virgin Cable MOdem. However I have seen people say that DHCP on the modem is only used when you are connecting a single PC to it and it gets ignore if you connect a router????

> you have a device on your network at 192.168.1.50 thats giving out bad ip information.
Well interestingly, 192.168.1.50 is my DNS-323 NAS box, which is assigned a Static IP address. I also have a netwprked printer with static IP of 192.168.1.60. Each of these devices are working fine and their addresses fall within the range available.
I did a quick check of my NAS box. Whilst it does offer the option of acting as a DHCP server, this is disabled.

Interestingly, the PC has booted & seen the network & internet fine for the past 2 days. During this time, the NAS box has been connected, so I don't think that's the cause of my problems.
I wonder whether, if the router is working correctly when the PC boots, it then hunts around and finds alternative sources? This has all arisen during a period when I've been trying to move from a Belkin Wi-Fi router to a TP-Link one.
At the moment, I've assigned a Static IP address of 192.168.1.50 to my NAS and this falls in the range of valid IP adresses set on the router (192.168.1.1 - 192.168.1.199).
Can I avoid this problem by setting the Static IP address to value outside this range (eg. 192.168.2.1) or do you think that the problem is happening just because this device is capabal of acting as a dhcp server (even though this function is disabled on it)?
As you can see, I don't know enough about network fundamentals......
