Windows 7 Wifi keeps crashing only for my Laptop

[Lordacus]

My laptop's wifi is lagging and its not lagging for other computers or smart phone devices, my friend even went to my house and had better wifi then me so it must mean that he has more priority or that it has to do something with my laptop, its a Toshiba laptop and my wifi provider is telus.

Check system manufacturer's support site for a driver update.

Also check the wifi manufacturer's site - http://sysnative.com/drivers/

Go into Device Manager and check under "Networking" for the wifi driver's name.
