Solution 2

Another issue for fluctuating speed could happen because of Power Save Polling (PSP) issues with Access points. According to Intel, if a WiFi router doesn’t support Power save Polling (PSP) feature, than it can create issues like, Intermittent loss of loss of Wi-Fi connection, Inability to initiate a Wi-Fi connection, Poor Wi-Fi connection data performance. These issues are most noticeable when the computer is on battery power.

PSP mode is a feature built to increase battery life of laptops and notebooks. However this mode requires a coordination between the Access point and the Wi-Fi router. But later on it was discovered by Intel that some access points or routers are not able to support PSP correctly or doesn’t support at all.

The only solution to check or ask manufacturer if there is any updated firmware of the router. If there is no such update, then there is one turn-around to set the wi-fi adapter of your computer to Continuously Aware Mode (CAM). Enabling this would disable the PSP feature. You can enable the CAM feature by following given methods:

  • Intel PROSet/Wireless WiFi Connection Utility
  • Network control panel applet (NCPA)

Be cautious, as this feature in some models can hinder Bluetooth functionality.
