    I got a new T400 with clean installed Windows XP Pro. Everything is perfect and there are no unknown devices in device manager. The only problem is that after the laptop wakes from standby it has very slow network connection, both in LAN connection and internet connection. After repairing the network connection, the connection speed back to normal. I use the Thinkpad a/b/g wireless card. Can anybody shed some light on this problem? Thanks!

    Did you install SP3 along with the hotfixes on the Lenovo driver page?

    yes, SP3 is already integrated into my Windows XP installation CD. I have installed all network related hotfixes. Still not work.

    Sounds like a power related problem. Did you config the wireless card for max performance instead of the power saving/balance default?

    Is the $20 upgrade for the configuration's other Thinkpad wifi card beneficial? What is different about it then the $20 cheaper one?

    @ roxshot: It is very likely, but I can't figure how to config the wireless card for max performance, there is no option in thinkpad power manager related to wireless card.
    I think its a driver problem, I have random crashes of Atheros Configuration Service (acs.exe) whose is the manufacture of the card.

    @ vaio boi: good advice, then we all should buy a mac at the first place, shouldn't we ?

    Do you mean upgrading to the Intel Wifi chips? I personally would, due to Wireless N and the fact that my router only likes Intel Wifi Cards. I have never had a problem due to my 5300, the 5100 in my mom's laptop, or the 4xxx in my Asus.

    Ok here is my fix, look in the properties of the wireless adapter in Device Manager, change the power saving option from "maximal" to "normal" or "off". Done

    My big thanks go to roxshot. I didn't know that we can change the power saving of each device in Windows Device Manger, lol.
