Symptom(s):
The following symptoms may be seen if a wireless access point (AP) or broadband wireless router does not properly support the power save polling (PSP) feature:
- Intermittent loss of wireless connection
- Inability to initiate a wireless connection
- Poor wireless connection data performance
These symptoms may be more pronounced when on battery power.
Cause:
Power save polling mode is a feature that provides extended battery life for notebook computers. It requires coordination between the AP or router and the wireless 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 that corrects the problem.
Alternate Solution
An optional workaround is to manually put the wireless adapter into continually aware mode (CAM). This disables the PSP feature. The wireless adapter can be put into CAM using the following methods:
Note: Implementing this workaround on certain systems with Bluetooth* co-existence may affect operability of the Bluetooth device. Contact your computer manufacturer for more information.
Use Intel® PROSet/Wireless Software to Set CAM
In the power management section, uncheck Default / Auto and move the slider to Highest / Maximum Performance.
If the slider is already at Highest / Maximum Performance, move the slider to another setting and then back to Highest / Maximum Performance.
Use Network Control Panel Applet (NCPA) to Set CAM
Put the wireless adapter into continually aware mode using the following steps.
1. Click Start » Control Panel.
2. Click Network Connections.
3. Right-click the wireless connection and click Properties.
4. Click Configure.
5. Click the Advanced tab.
6. In the power management setting, uncheck Default / Auto and move the slider to Highest / Maximum Performance. Note: If the slider is already at Highest / Maximum Performance, move the slider to another setting and then back to Highest / Maximum Performance.
