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:
- Click Advanced > Adapter Settings > Advanced tab.
- Windows XP*: Select Power Management, uncheck Default / Auto, and move the slider to Highest / Maximum Performance.
- 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:
- Click Start > Settings > Control Panel.
- Double-click Network Connections.
- Right-click the wireless connection and click Properties.
- Click Configure.
- Click the Advanced tab.
- Windows XP: Select the Power Management setting, uncheck Default / Auto, and move the slider to Highest / Maximum Performance.
- 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. | |
