IBM-Lenovo X61

My colleague received an IBM-Lenovo X61 laptop, and we found that built-in Intel 4965 wireless is very slow when connected to 802.11b access point. Same problem persisted both with Fedora Core 8 and Ubuntu (iwlwifi driver).

Usual tweaking of ACPI and APIC parameters didn't help. Googling around showed a lot of people suffering from the same problem with Intel 4965 wireless cards. Eventually I resolved the problem by removing iwlwifi driver files from /lib/modules, and installing ndiswrapper (allows to use Windows network drivers) + Intel 4965 driver for Windows XP.
