Wifi-Connected but no internet

There was a lot of great help with my last issue here
It seems Windstream solves one problem and two more appear.

After a two day outage at the beginning of the week, I was restored and thought all was well.
My desktop is wired and was finally working well.
My wife came home from work and couldn't get online.
Her desktop is wireless
I monkeyed around trying to reinstall the network adapter and a bunch of things.

The error was "Connected-no internet access"
It also affected my tablet and wifi enabled phone from Republic wireless.
I was able to get the desktop working by changing the TCP/IP settings but the phone and tablet won't work and I can't figure out how to configure these settings on them.
I have an Asus Android tablet and a Motorola Defy phone
The phone is more critical of the two.

The message on my phone is "Wifi calling disabled-click to configure"
I have entered the password several times but I can't figure out how to change the real settings like I did on the desktop.
It turns out my Wifi printer doesn't work either

Thanks
