What dual band ac wireless adapter?
What operating system? What version?
What is the model number and manufacturer of your device?
Is this a laptop? If so, is there a (hard or soft) switch on the laptop to turn on and off the wireless?
Provide more information.
Did you recently go through a major Windows 10 update (for example, from 1803 to 1809 or from 1809 to 1903)? If so, the graphics drivers are sometimes screwed up by the update. Use a process like this to try and recover:
Hope this helps,
My apologizes. I am on my own laptop asking for help, because my daughters laptop does not have any internet. there is no physical button to press to turn wireless on/off, as there is no enthernet plug to connect wired. There doesnt seem to be any other internet options she can use. I think I may need to purchase an adapter or take it in for service. Thoughts?
One more thing to check - if there is no physical button, check to see if there is a soft (or touch sensitive) button. Usually indicated by the wireless icon. It may be illuminated when ON.
Other than that, follow Scott's instructions. From your laptop, download the drivers and put them on a usb stick, and use that on the other laptop.
