Lenovo x60 wireless problem

Try checking in control panel>system>hardware>device manager>network adapters>wireless adapter: right-click> properties > advanced, whether it says "wireless on" next to the intel sign.
Worked on mine X60.

Verify that the radio is enabled.
It is possible to disable the transmitter of the wireless card without Device Manager showing any problems.
Note: Follow the instructions provided to enable wireless card.

• Most wireless cards will put an icon in the system tray (the line of icons in the lower right corner of your screen). Right click this icon and it may have a menu option to enable/turn on the wireless radio.
• Some systems come with a Wireless Radio switch to disable the wireless radios. The wireless radio switch is usually located on the front side of the machine. If you are having difficulties with wireless connections, make sure the Wireless Radio switch is set in the On position.
  
• Check for association to an Access Point.
  If you double-click the previously mentioned system tray icon, the configuration utility of the wireless card will appear. This utility will be able to show the status of the wireless card, showing what channel the card is using and what signal strength is being received. It may be difficult to maintain a connection if signal strength is low due to either interference or distance. For example, interference can be caused by 2.4GHz cordless phones, other Access Points in the area, and physical structures such as load bearing walls or metal partitions.
  Note: The utility can be used to configure the wireless card settings, but if using Windows XP Zero Configuration or Access Connections, you will need to use those programs to actually configure the wireless card as they will overwrite the setting of the utility.
  

Check if there's a physical switch for wireless. The t6x series have them.
