A lot of carriers and ISPs may be in disarray. Call this in before you begin repairing what may be all good on your end.
A few weeks ago the power went out during a storm and when everything went down we started having internet issues. It seems whenever a computer goes to sleep or turns on it cannot connect to the internet. While you're connected and surfing everything works fine but as soon as the computer sleeps it comes back up with the little warning over the wi-fi connection.
It says connected with no internet. I've tried ipconfig and it looks like everything is still talking and i went into the router and none of the settings reset during the outage. I'm at a loss here. I am either told by the troubleshooter that there is a DNS error or that the default gateway is not available. Which leads me to think this is a modem issue? Are there any ways to test this?
