Molostoff Wasiliy, спасибо за совет, попробую.
Кстати, про переключение в режим
802.11b only я погорячился, все таки иногда возникает проблема.
В процессе копания нашел еще вот что:

PSP (Power Save Polling) Causes Connection Issues With Some Access Points
Symptom(s):
If the wireless access point / wireless gateway does not properly support the PSP feature, intermittent loss of wireless connection, inability to initiate a wireless connection, or poor wireless connection data performance could result. The symptoms may be more pronounced when on battery power.
Cause:
In a mobile environment, power save polling mode is a feature for extended battery life for mobile stations. The capability requires coordination between the access point and the laptop's wireless adapter for proper operations. Intel has discovered the feature may not be implemented correctly or completely in some wireless access points or wireless gateway devices.
Solution:
Contact the access point vendor for an updated software which corrects the problem.
As a temporary workaround, manually set the adapter to CAM (continually aware mode), which disables the PSP capability. To do this, in either Intel® PROSet for Wireless Software or the Network Control Panel Applet (NCPA), in the power management section, uncheck the DEFAULT / AUTO selection and set the slider for HIGHEST / MAXIMUM PERFORMANCE
Notes:
To ensure the adapter is set to CAM - if the slider is already at the HIGHEST / MAXIMUM PERFORMANCE setting, move the slider to another setting and then back to HIGHEST / MAXIMUM PERFORMANCE.
On certain systems implementing Bluetooth* Co-existence, putting the WLAN NIC into CAM Mode may affect operability of the Blue tooth device. Check with your computer manufacturer for more information.
Your laptop may or may not have the PROSet for Wireless Software or you may be using a software version that does not include this setting. In this case use the NCPA to make the settings change.
The NCPA is accessed via Start >> Control Panel >> Network Connections >> then right-click to select Properties >> Configure >> Advanced Tab. For software version 9.x and later, the NCPA can be accessed through advanced...adapter menu choice.
With AUTO (PROSet) or USE DEFAULT VALUE (NCPA) selected, the adapter attempts to make a balance of battery life vs. performance by setting to a higher level 1 if the laptop is on AC power, and to lower level if on DC power.
Не знаю, насколько это применимо к моему случаю, тем не менее последовал совету
in the power management section, uncheck the DEFAULT / AUTO selection and set the slider for HIGHEST / MAXIMUM PERFORMANCE
Посмотрим что получиться
