Sony laptop nearly new, windows 7, didnt have any problem until last week, have not changed any settings that i am aware of. One day I just could not get on the net. Good signal to wireless router but no internet access. Eventually tracked prob down to above, each time i switch on i have to go back in to Internet protocol V 4 properties and select obtain DNS server address automatically
If I am on line for a reasonable length of time i have also noticed (once) it changed during a session
How can i get it to stay on obtain DNS server address automatically

Hi,
How long have you been facing this issue?
I would suggest you to scan your computer for virus and check if it helps, it might be a virus issue.
You can also try performing online complete PC virus scan on your computer and check if it helps, here is the link:

After switching off overnight the same problem has recurred, please can anyone else help?
I have had the same problem. Brand new Sony VAIO VPCX11S1E running W7. It happens to me when I move between different wireless networks with different default gateway/DNS addresses. The automatic setting is always set to manual 192.168.2.1. I can of course reset manually - but this is a pain. I don't normally reboot, i.e. this might also be tied up with sleep/hibernation recovery. I have no virus or corrupted software problem. It is a software bug - either Microsoft or some of the Sony supplied stuff.
I hope someone can advise a work round, clearly there are 1000's of us out there suffering.
same problem here, windows 7 on a dell inspiron
I'm having the same problem on Dell Optiplex running XP. I'm wired only, so no wireless issues. Have run anti-virus scans. It started a couple weeks ago, but not every time I've booted up. It's happened 3 times now. Again today.
