The icon next to the network name provides a visual status for the radio. It is only
available when all of the following is true:

(four-bar)
(Encryption)
(fail)
A strong signal (four bars) usually means that the wireless network is close or there is no
interference. For best performance, connect to the wireless network with the strongest
signal. However, if an unsecured network has a stronger signal than a security-enabled
one, it's safer for your data if you connect to the security-enabled/encrypted network
(but you must be an authorized user of that network).
To improve the signal strength, you can move your mobile computer closer to the
wireless router or access point, or move the router or access point so it's not close to
sources of interference such as brick walls or walls that contain metal support beams.
4) Tap the network you would like to connect to, or tap Add New... to add a new network
to the available network list. A settings page will open specifying the type of network to
connect to (Internet or Work). Tap Next and follow through the next pages to set up
connection. If the selected network has an encryption method, deselect "The key is
automatically provided" and enter the network key in the field below.
When done, tap Finish to return to Wireless tab.

is associated) is -91 dBm or weaker.
The RSSI for the current AP is -90 dBm or stronger but no more
than -82 dBm.
The RSSI for the current AP is -81 dBm or stronger but no more
than -72 dBm.
The RSSI for the current AP is -71 dBm or stronger but no more
than -68 dBm.
The RSSI for the current AP is -67 dBm or stronger.
The RSSI for the current AP has data encryption for connection.
The signal for the current AP is unavailable.
