Q: Why can’t I find my friend’s device while using Bluetooth connectivity?

A: Check that both devices are compatible, have activated Bluetooth connectivity, and

are not in hidden mode. Check also that the distance between the two devices is not

over 10 metres (33 feet) and that there are no walls or other obstructions between the

devices.

Q: Why can’t I close a Bluetooth connection?

A: If another device is connected to your device, you can close the connection using the

other device or by deactivating Bluetooth connectivity. Select

Menu

Ctrl. panel

Q: Why can't I see a wireless LAN (WLAN) access point even though I know I'm

within its range?

A: Check that the Offline profile is not in use in your device.

The WLAN access point may use a hidden service set identifier (SSID). You can only access

networks that use a hidden SSID if you know the correct SSID, and have created a WLAN

access point for the network on your Nokia device.

Check that the WLAN access point is not on channels 12-13, as they cannot be associated

with.

Q: How do I turn the WLAN off on my Nokia device?

A: The WLAN on your Nokia device deactivates when you are not connected or trying to

connect to another access point, or not scanning for available networks. To further

reduce battery consumption, you can specify that your Nokia device does not scan, or

scans less often, for available networks in the background. The WLAN deactivates in

between background scans.

To stop the background scans, select

Menu

>

Ctrl. panel

>

Settings

and

Connection

>

Wireless LAN

>

Show WLAN availability

>

Never

. You can still manually scan for

available WLANs and connect to WLANs as usual.

To increase the background scan interval, select

Show WLAN availability

>

Yes

, and

define the interval in

Scan for networks

.
