VISTA Wireless Connectivity problems

Consequently, Microsoft modified the default power setting for 802.11 wireless adapters from Balanced to Maximum Performance. But the issues are in fact related to prioritizing battery life over functionality. And there is an intimate dependency between the power savings scheme for 802.11 wireless adapters and the access point. “When power save mode is enabled for an 802.11 wireless network adapter, the adapter periodically enters a low-power state where the radio transmitter and receiver are in “sleep” mode. The wireless adapter in the computer (client adapter) indicates the “sleep” mode by setting the power save option in its packets or 802.11 frames sent to the access point,” added Leznek.The power save options determine the access point to debut buffering packets while the adapter is asleep and only temporarily wakes up to receive the buffered packets. As the default power saving setting for the 802.11 wireless adapter is now Maximum Performance, you can switch it back:Change the wireless power saving setting: - Open Power Options in Control Panel - Choose Change Settings for the current power plan - Choose Change Advanced Power Settings - Expand Wireless Adapter Settings - Expand Power Saving Mode- Choose Maximum Power Saving, Medium Power Saving, Low Power Saving to enable various levels of 802.11 power save modes.Choose the Power Saver power plan: - Click on the battery meter on the desktop and choose Power Saver. - The Power Saver plan has 802.11 power saving mode enabled for both battery and AC power.
