Step 2:
Try updating the device driver from device manager, steps to follow
i. Click Start, type devmgmt.msc and then press enter
ii. From the list of items expand the network adapter’s device, right click the sub item and then select Update driver.
Step 3:
Uninstall and reinstall the network adapter from Program and features. Steps to follow
i. Click Start and choose Control Panel
ii. In Control Panel double click on the "Programs and Features" icon.
iii. Here you can find all the programs and items which are installed in Windows 7.
iv. To remove the device click once on the program and then click on Uninstall/Change and follow the prompts.
