Before you run the test, complete the test setup as described in the test requirements: Wireless LAN (802.11) Testing Prerequisites.

The following suites are available:

  • Performance_cmn

The Performance_cmn suite consists of the following:

Name Description

Send data from the DUT to an access point and collect statistics (cipher: {0}, packet size: {1}, packet lists per send: {2}, time duration: 30 seconds})

Ciphers used: None,WEP,TKIP,CCMP

Packet size: 1500

Send data from an access point to the DUT and collect statistics (cipher: {0}, packet size: {1}, packet lists per send: 40, time duration: 30)

Ciphers used: None,WEP,TKIP,CCMP

Packet size: 1500

Send data from the DUT to an access point and verify the send data rate (cipher: None, packet size: 1488, packet lists per send: 21, time duration: 30, data rate sample interval: 5ms)

  • Verify that a driver does not return an outdated scan list on resume with a forced active scan.

  • Verify that a driver does not return an outdated scan list on resume without a forced active scan. Do not connect to the first access point. Shut down the first and second access point with delay. Resume the DUT when it hibernates.

  • Validate that a driver does not return outdated scan list on resume with forced active scan

  • Verify that a driver does not return an outdated scan list on resume without a forced active scan. Connect to the first access point. Shut down the first and second access point with delay. Resume the DUT when it goes to standby.

  • Verify that a driver does not return an outdated scan list on resume with a forced active scan.

  • Verify that a driver does not return an outdated scan list on resume without a forced active scan. Do not connect to the first access point. Shut down the first and second access point with delay. Resume the DUT when it goes to standby.

  • Verify that a driver does not return an outdated scan list on resume with a forced active scan.

VerifyScanningAfterResumingFromSleep

Hibernate the DUT and verify that DUT miniport completes a scan within 4 seconds after resuming from hibernate.

VerifyLowPowerSameNetworkSameAP

  • Verify that the DUT successfully associates with a hidden access point within 1 second after resuming from hibernate.

  • Verify that the DUT successfully associates with a visible access point within 1 seconds after resuming from hibernate.

VerifyLowPowerSameNetworkDifferentAP

  • Verify that the DUT roams to a new hidden access point after the original access point disappears during hibernate. The DUT must successfully associate with the new access point within 4 seconds after resuming from hibernate.

  • Verify that the DUT roams to a new visible access point after the original access point disappears during hibernate. The DUT must successfully associate with new access point within 4 seconds after resuming from hibernate.

VerifyScanningAfterResumingFromSleep

Put the DUT into standby mode. Verify that the DUT miniport completes a scan within 4 seconds after resuming from standby.

VerifyLowPowerSameNetworkSameAP

  • Verify that the DUT successfully associates with a hidden access point within 1 second after resuming from standby.

  • Verify that the DUT successfully associates with a visible access point within 1 second after resuming from standby.

VerifyLowPowerSameNetworkDifferentAP

  • Verify that the DUT roams to a new hidden access point after the original access point disappears during Standby. The DUT must successfully associate with the new access point within 4 seconds after resuming from standby.

  • Verify that the DUT roams to new visible access point after the original access point disappears during standby. The DUT must successfully associate with the new access point within 4 seconds after resuming from standby.

Troubleshooting

For troubleshooting information, see Troubleshooting Wireless LAN (802.11) Tests.

If you receive the failure message Cannot load Counter Name data because an invalid index was read from the registry, the performance counters in the system need to be rebuilt. This can be done by using the following procedure:

To rebuild the performance counters in the system

  1. From an elevated command prompt, run the following command:

    lodctr /r

    You will receive the following message:

    Info: Successfully rebuilt performance counter setting from system backup store.

  2. After this action, some providers might be disabled. Run the following command to check status:

    lodctr /q

    The output will be similar to the following:

    Performance Counter ID Queries [PERFLIB]:    Base Index: 0x00000737 (1847)    Last Counter Text ID: 0x00001560 (5472)    Last Help Text ID: 0x00001561 (5473)[.NET CLR Data] Performance Counters (Enabled)    DLL Name: netfxperf.dll    Open Procedure: OpenPerformanceData    Collect Procedure: CollectPerformanceData    Close Procedure: ClosePerformanceData    First Counter ID: 0x00001080 (4224)    Last Counter ID: 0x0000108C (4236)    First Help ID: 0x00001081 (4225)    Last Help ID: 0x0000108D (4237)

  3. If it says (Disabled) next to a provider, you can enable it by using the following command:

    lodctr /e*:<provider name>*

    Where <provider name> is the string between the [ ] brackets at the start of the entry.

  4. Rerun the test.
