I have a strong feeling that some kind of power management routine lowers the power of my wireless card, so when I disconec t the power cord connection starts dropping. Is that possible? If so, how can I change that?

Another weird thing has happened. I was having no trouble connecting to the net thru a wireless router suddenly I am getting the “Limited or no connectivity” warning and things stoped working. I already have SP2 installed. Anyone knows what is it about?

make sure the power save mode is off.

Where at? Power management utility or on the specific wireless card settings?

device manager->network adapters->802.11 miniPCI adapter->advanced tab->power save mode

Mine is set to automatic by default. Does it influnece the quaklity of signal? Did you change that setting?

I would suggest putting it on maximum for both battery and AC power.  That way you won’t notice any difference in signal strength.  And if you’re worried about battery life I can’t believe it’ll make any noticeable difference…

I think that the power cord works as a ground for the antenna.
It is not a software problem.
This effect are in many wireless devices the same.
With AC power you can get better signal strengt.
