We had similar problem few years ago when using Cisco PCMCIA NICs and Dell
laptops - solved by using MiniPCI NICs instead.
If you really really really need the solution for existing NICs, try the
following:
* Disable IBM/Lenovo NIC and use another one - eliminates problems related
to your NIC configuration
* Unbind _all_ service from the wireless network connectiuon object and
enable one by one, starting with plain TCP/IP. Eliminates the problems
related to the additional service ie 3rd-party 802.1x supplicants
* Place a computer on the same physical subnet with DHCP server
Might be a support case.
