Trying to identify correct WLAN Adaptor [ Edited ]

[lefrana]

I'm trying to identify what WLAN Adaptor is installed on my T400 so that I can download the correct drivers for Windows 7.

When I do a parts lookup on the Lenovo Support Site, I get the following result:

Mfg part #   43Y6510 
FRU part #  43Y6511       
Description: HARRISON WLAN ADAPTER FRU

On the Lenovo Driver Matrix for T400, I don't see drivers for any Wireless Adaptors that fit this description.

Anybody know which Wireless Adaptor this info corresponds with?

System Specs:

ThinkPad T400 2764-CTO

Intel Core 2 duo P8600 2.40 GHz

3 MB RAM

Windows 7 Ultimate 32-bit

this is a thinkpad wireless card not the intel wireless card.

Thanks.  The Lenovo support site unfortunately doesn't seem to have Win 7 drivers for that particular card, only Vista drivers.

I think this is the one you're looking for:

I don't think those are the correct drivers unfortunately.

I've identified my adaptor as the ThinkPad 11b/g Wireless LAN Mini PCI Express Adapter III.

The drivers your directed me to are for ThinkPad 11b/g/n Wireless LAN Mini-PCI Express Adapter II.

I've actually tried them anyways but no luck.

Have you tried running the System Update tool?

I've also seen someone here reporting WLAN issues was suggested to make sure that his wireless adapter is set to high performance.

Yeah, System Update doesn't find any new drivers for my WLAN card unfortunately.

I've adjusted all power settings but nothing seems to be helping. 

Oddly, Windows tells me that my wireless signal is 'Excellent'.  However, I've noticed that when I ping my router, I get packet loss of any where from 25-75%.  I have two other laptops on my network (a T500 and a Mac Book pro) and neither are having any issues so I don't think the router is the issue.
