You wrote it won't connect and it is connected.
Turning on bluetooth. That's one thing.
Connecting or PAIRING, that's entirely something else.
Many folk are lost at first. There are many fine YouTubes now but here I'm reading your post and it's unclear to me.
I have a new Dell computer. I bought it about 6 months ago. I have recently tried to use my Bluetooth on it. It has an area under settings that says Bluetooth, but when I click on it and turn on my Bluetooth, it doesn't connect. It just searches. Is this because my Bluetooth is connected to my IPad which is also in the same room? Or does this mean I need a Bluetooth adapter? Any help would be appreciated.
