Device says connected but have no internet access

We had a electrical power outage last week. Ever since then we've been having issues accessing the internet on two laptops and one smartphone. Every other device works (three other smartphones, three roku's and two tablets, etc), it's just those three devices. It's driving me crazy that ever since that outage three of our devices that had no trouble at all accessing the internet, now says there's no access. The strange thing is they show they're connected but it comes up as no internet access. Help please...

Re: Device says connected but have no internet access

Could also be a loss of one of the wireless radios and the affected devices don't know to look on the remaining band for the other SSID.  First tell us what networks you see listed on a working device, then on one of the three units that will not connect.
