I have seen similar threads but nothing there has worked... (The option to turn the wifi off to save power is unchecked.)
I just got a new laptop (Samsung Ativ 7) and it worked great for a week on the router I have at home. I just moved into university housing and the wifi seemed to work for about a day, but since then (about 3 days now) it continuously disconnects from the internet. Like every 30 seconds... It's bad. If I'm lucky I'll get a few minutes, though strangely the problem seems to be getting worse each day and my time online seems to be getting shorter each day.
When I run the troubleshooter, it says the default gateway is not available and "fixes" the problem, which lasts for a few seconds/minutes before it reverts. Every now and then the problem will be "Wi-Fi doesn't have a valid IP configuration." That problem gets "fixed" and the internet never works, instead I have to trouble shoot again to see the gateway one, then I get a little bit of wifi. Lately I have to run troubleshooter multiple times before I get any results.
I think I'm having DNS issues, but what the cause or the solution is, I do not know... The lease is always listed for about 5 minutes (though I don't always make it that far) and when I try to connect the college VPN service, it says "Limited Access - DNS Failure."
My IPConfig info is below. Please let me know if I can do anything else to help
