Enable the 5100 wireless network card of Lenovox200 to work properly on Ubuntu8.04

Lenovox200 uses the new wireless 802.11n wireless network card 5100, which greatly improves the speed. This new wireless network card cannot work properly on 8.04. (Ubuntu8.10 can work normally ). to use Ubuntu, you must install the driver on your own. below is a record of the method (in fact, it is a method of foreigners ). first go to this website http://wireless.kernel.org/en/users/download, download if your core is greater

Because the Lenovo x200 uses a new wireless 802.11n wireless network card 5100, the speed has been greatly improved. This new wireless network card cannot work normally on 8.04 (Ubuntu 8.10 can work normally ).
If you want to use Ubuntu to work normally, you need to install the driver yourself. The following is a record of the method (in fact, it is a foreigner's high-tech method ).
Go to this website http://wireless.kernel.org/en/users/download, download if your kernel is greater than or equal to 2.6.27:
Http://wireless.kernel.org/download/compat-wireless-2.6/compat-wireless-2.6.tar.bz2
If your kernel is less than or equal to 2.6.26:
Http://wireless.kernel.org/download/compat-wireless-2.6/compat-wireless-old.tar.bz2
Decompress the package, and use su to become the root permission.
Sudo su
Cd/usr/src
Tar xjf compat-wireless-2.6.tar.bz2
Cd compat-wireless-2008-10-03
Modify the config. mk file to enable 5100 Wireless wifi support.
CONFIG_IWL5000 = y
CONFIG_IWLWIFI_RFKILL = y
Compile compat-wireless, install and use make load to load.
Make
Make install
Make load
The iwl4965 kernel module is used when the 5100 wireless driver is loaded using load. This is only used now. The iwl5000 module will be used after kernel 2.6.26.
Download firmware iwlwifi-5000-ucode-5.4.A.11.tar.gz 5100
Copy the following firmware to the relative position of the kernel based on your kernel:
Tar xzf iwlwifi-5000-ucode-5.4.A.11.tar.gz
Sudo cp iwlwifi-5000-1.ucode/lib/firmware/2.6.24-21-generic/

Then you can restart the instance and use lshw to view the instance. If configuration: broadcast = yes driver = iwl4965 latency = 0 module = iwl4965 is available, the instance is loaded successfully.
