Power Save Polling (PSP) Causes Connection Issues with Access Points

Symptom(s):

The following symptoms can happen if a Wi-Fi access point (AP) or broadband Wi-Fi router does not support the power save polling (PSP) feature:

  • Intermittent loss of Wi-Fi connection
  • Inability to initiate a Wi-Fi connection
  • Poor Wi-Fi connection data performance

Using battery power can cause these symptoms to be noticeable.

Cause:
PSP mode is a feature that provides extended battery life for laptop computers. The mode requires coordination between the AP or router and the Wi-Fi adapter. Intel has discovered that some APs or routers may not implement the feature correctly or completely.

Solution:

Contact the AP or router vendor for updated software or firmware to correct the problem.

Alternate solution:
An optional workaround is to manually put the Wi-Fi adapter into continuously aware mode (CAM). This disables the PSP feature. Set CAM by using one of the following methods:

  • Intel® PROSet/Wireless WiFi Connection Utility
  • Network control panel applet (NCPA)
Note Using this workaround can cause your Bluetooth® device to not receive signals. Contact your computer manufacturer for more information.

Set CAM using Intel® PROSet/Wireless WiFi Connection Utility

From the Intel PROSet/Wireless WiFi Connection Utility:

  1. Click Advanced > Adapter Settings > Advanced tab.
  2. Windows XP*: Select Power Management, uncheck Default / Auto, and move the slider to Highest / Maximum Performance.
  3. Windows 7 or 8*: Select Transmit Power, change Value to 5. Highest.
Note If the slider is already at Highest / Maximum Performance, move the slider to another setting and then back to Highest / Maximum Performance.

Set CAM using network control panel applet (NCPA)

Put the wireless adapter into continuously aware mode using the following steps:

  1. Click Start > Settings > Control Panel.
  2. Double-click Network Connections.
  3. Right-click the wireless connection and click Properties.
  4. Click Configure.
  5. Click the Advanced tab.
  6. Windows XP: Select the Power Management setting, uncheck Default / Auto, and move the slider to Highest / Maximum Performance.
  7. Windows 7 or 8: Select Transmit Power, change Value to 5. Highest.
Note If the slider is already at Highest / Maximum Performance, move the slider to another setting and then back to Highest / Maximum Performance.

Operating System:

Windows 7 *, Windows XP *, Windows 8*
