WLAN troubleshooting
WLAN functionality test using SB-7 and Phoenix
Steps
1. Place the phone on the SB-7 WLAN test box (see figure below). The co-ordinates are A1 (for the upper left
foot).
2. Start the phone to normal or offline (RF inactive) mode.
3. Search for SB-7 WLAN test box via the phone's Operator menu. Go to Menu→Oper. menu, and the
connection pop-up window appears. Select Search for WLAN. If the phone is in offline mode, select Yes
when the question
4. Select the default WLAN network. WLAN connects to the SB-7 access point, which is named "default". You

will receive a
However, you are now connected to SB-7.
5. Check the signal level from the Connection Manager menu. Go to
Menu→Crtl. panel→Connectivity→Connection Mgr.. You should see the "default" connection in the
connection list with the connection time running. Go to Options→Details. Observe the signal strength.
"Signal" should show a signal strength Medium (50%) or higher.
Note:
Local WLAN environment may affect test results, especially if there are many WLAN access
points nearby and any of them are using the same WLAN channel as SB-7. If you have problems
performing the test, consider repeating the test where local networks do not interfere with the
lower strength signal of the SB-7 box.
If you still cannot find the WLAN test box name "default" after scanning the networks, or if you have
connected to the test box but signal strength is lower that 50%, the phone is not ok. In that case,
proceed to WLAN failure troubleshooting.
WLAN layout and test points
The WLAN module has been optimised to achieve the smallest possible PWB area and adding test points will
compromise this layout efficiency. There is also an added risk that test point will compromise the WLAN
performance. Therefore there are no test points in the WLAN layout. Software tests will be used instead to
verify the operation of the WLAN module. The WLAN schematic is provided below.
