Hi,
Have you tried connecting your speaker to a different device? Does it connect successfully?
Make sure your speaker is fully charged and in pairing mode. Check the manual if you’re unsure how to enter pairing mode.
On your laptop, go to Settings > Bluetooth & devices and ensure Bluetooth is turned on. Click Add device > Bluetooth, then select your speaker from the list. If it doesn’t appear, turn Bluetooth off and back on, or restart your laptop and try again.
If it still won’t pair, remove any old pairing records for the speaker by going to Devices > Your speaker > Remove device, then try pairing again.
Also, make sure your Bluetooth driver is up to date:
Press Windows + X and select Device Manager.
Expand the Bluetooth section.
Right-click your Bluetooth adapter and choose Uninstall Device.
Check the box for Delete driver software for this device if prompted.
Look under Bluetooth or Other devices for any previously connected Anker Bluetooth speaker entries. Right-click each one and select Uninstall.
Restart your computer and then try pairing the speaker again.
Check that Windows Audio services are running:
Press Windows + R, type services.msc, and ensure Bluetooth Support Service and Windows Audio are running. Restart them if needed.
