My desktop has stopped acknowledging my wireless mouse.

Question

THis has happened once or twice before. WHen I took it in they couldn't find anything wrong and it was working fine. (of course). I have changed the batteries. The light on the mouse flashes correctly, so it is "discoverable". Now, Bluetooth doesn't even appear in my system preferences. When I search apps for Bluetooth, many folders and files appear.....no idea what any of them are. It was working just fine, twelve hours ago. Other wireless is fine.

Answer 1

What wireless modes did you enable?
802.11a/b/g/n? All or any specific one?
iDevices support n and g. I'm not sure if setting your wireless modes to n only or g only will help, worth a try though. Another possibility is you've checked "Do not broadcast SSID (network name)" on your router which is why it's a hidden network".
Enabling use of hidden networks
Wi-Fi
Other network
Enter network name, case sensitive
Set the correct encryption or type of security
Enter password
Done.
Alternatively, you may enable SSID broadcast by going to the router's default gateway page. This can be accessed by finding the number through (Im telling a windows method as Im a windows user)
run "cmd"
ipconfig -all, look for default gateway
Type the default gateway numbers with the mask "." into the browser URL bar.
Enter router settings password
Locate your wireless network settings and make the appropriate adjustments. (You may need to consult the user manual
Does it help?
or
if you have changed Wi-Fi password, then you can probably try clicking the tiny blue arrow beside the network on your Wi-Fi screen,
"Forget this network"
Re enter the password
