Hello, You might want to try installing the latest version of the driver from Lenovo's support web site:
ThinkPad 11b/g/n Wireless LAN Mini-PCI Express Adapter II for Windows XP http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS003636 ThinkPad 11b/g/n Wireless LAN Mini-PCI Express Adapter II for Windows 7 http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS000979 The card uses a Realtek chipset, so you could also try the latest version from Realtek, if the Lenovo drivers don't solve the problem: http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=21&PFid=48&Level=5&Conn=4&ProdID=226&DownTypeID=3&GetDown=false&Downloads=true#2281 I have two X100e's and found the performance of the ThinkPad 11b/g/n Wireless LAN Mini-PCI Express Adapter II in them to be sub-par, so replaced them with a Lenovo-branded Intel WiFi Link 5100 half-height mini-PCIe WLAN card (P/N 43Y6517) and that seemed to solve my issues. That was before all of these newer drivers were available, though. Regards, Aryeh Goretsky At 10:00 AM 3/24/2012, you wrote:

To: Thinkpad Users Group <[email protected]> Message-ID: <[email protected]> Content-Type: text/plain; charset=ISO-8859-1; format=flowed I have a Thinkpad that I had to rebuild, without the original CDs. Fine--I built it with my own XP CD and got everything working. This is an X100e, the small, cheap, but actually pretty good notebook. Except wireless, sort of. The user can do wireless at a coffee shop, or at work, just fine. He can't connect to his wireless router at home. Someone else in his family can talk to the router without problem. Thus we know that the thinkpad in question works, and the wireless router works--just not this notebook and home routeer. Having him do ipconfig commands, he gets a 169.x.x.x address which is the failure to complete a DHCP handshake. I used the thinkvantage system which was great, in that I got all the thinkpad specific stuff, but may also a newer version of the wireless driver, which is the source of the problem, I'll bet. The original factory install of XP worked just fine. So then, my question is how do I find previous versions of drivers? I've looked and perhaps I'm blind but I haven't found them. The user is connected via ethernet at the moment, but I have lots of users who see the net as wireless only. Ideas? I've never had to roust backwards in versions of wireless before. Of course, if someone has seen this and has a fix I'd love to hear it. Thanks...... --STeve Andre'
