    I don't know if it's just me or something, but my T400/5300wifi works more stable when plug in with AC power than on battery.

    when I am just using battery, the wireless performance is horrible and I have to reconnect to the AP to get connected. otherwise it is just stuck there with "Looking up the host name....." BS. But it works much better when I plug it in. I don't see any difference interms of signal strength tho.

    Anyone has similar experience? or is it some sorts of defect?

    My T400: P8600 /2G/80G 5400/2G TurboMem/5300AGN and running vista home basic

    My U6 has several Power4Gear options:

    1. High performance, Wi-Fi on Max
    2. Quiet Office Wi-Fi reduced
    3. Entertainment, Wi-Fi reduced.
    4. Battery Saving, Wi-Fi is a snail.

    It is normal for the adapter to work 100% on power. Software does not tell it to conserve battery :p.

    If, however, your adapter is not working properly on battery when you are in high performance then you need to update the drivers/rollback or send it back because it is broken :(.



    P.S. We have different Wi-Fi chips but the principle is the same.

    Make certain all power-saving features are off with regard to your wireless card. Some wireless access points do not support power-saving wireless clients properly and this is the reason, by default, Windows Vista shuts off power saving in the wireless card. However, I believe Lenovo, in their infinite wisdom, has power saving for the wireless card turned on by default.

    I have the Intel 5300 as well, no power saving, and the card is practically flawless.

    I have maximum power savings on the 5300 turned on and never experience dropped connections.
    Are you sure your past experiments were controlled?

    This is one of those cases where they can’t be controlled—especially if you use your notebook outside of a controlled environment. Here’s Microsoft’s own Knowledge Base article on the topic:

    You may experience connectivity issues or performance issues when you connect a mobile PC that is running Windows Vista to a wireless access point
