I want the wi fi drivers for my Lenovo laptop

Sometimes it is incompatible devices, while standard wi-fi everything should work. Try updating the driver on wi-fi card, change the channel, and encryption type.

Make sure Wi-Fi is turned on your device
Make sure flight mode is turned off
Make sure your selecting the correct wireless name in range and using the correct network password to connect, Wireless networks with low signals will show connected but you will not be able to browse the internet
Check your router and modern, Make sure the lights are as mentioned in the user guide of your service provider
First figure out if the problem is with your Lenovo Device or the Wi-Fi network:
Device/Machine problems: Try connecting to the Wi-Fi network with another device, like a laptop computer or friend's phone. If any other devices can connect to and use the wireless network, the problem is most likely specific to your device.
Network/Router problems: Check to see if your device can connect to a Wi-Fi network at another location, like a friend's house or a public network. If it can, the problem is most likely specific to the Wi-Fi network.
Then try the troubleshooting steps below based on whether the problem is with your device or the network.

try reinstalling the wireless card drivers!

try the lenovo website: http://consumersupport.lenovo.com/en/driversdownloads/drivers.html
select the first option, type the serial number of your computer and hit search. Under the networking wireless category, select the driver for intel wifi link that is compatible with your operating system

A list of all drivers, including wi-fi, can be found here: http://www-307.ibm.com/pc/support/site.wss/product.do?subcategoryind=0&familyind=437897&brandind=10&doccategoryind=0&modelind=0&doctypeind=9&validate=true&partnumberind=0&sitestyle=lenovo&template=%2Fproductpage%2Flandingpages%2FproductPageLandingPage.vm&operatingsystemind=49979&machineind=0

Just make sure you pick the correct wireless driver - this model could be using Intel or GemTek wireless chipsets. If you're not sure, try the Intel driver first, then the GemTek.

Good Luck!

this is because your wi-fi is not properly installed. check on the lenovo site and download the wi-fi driver then install it.
