Inspiron 11 Wifi stopped working

I am working on an Inspiron 11, just before the 3000 series, purchased in 2014. I was working online, walked away, and 5 minutes later, the wifi just stopped receiving. I have restarted, rebooted, checked every switch, setting and possible issue - no luck. Any ideas or anyone else have this happen? And please don't ask if I have tried other wifi networks. I have- 4 different ones.
