I've recently formatted my laptop and I'm having problem with speed of my Wifi when connected to the laptop dell inspiron n5050.Can any one help?

Thank you for your message.

What is the connectivity speed you get?  What is the OS installed?

Did you complete the Windows updates & drivers? If not please update from www.support.dell.com

For my reference, please click on my Dell username. & send a private message with the service tag, registered name & email address.

My normal internet is of 30 mbps. All the devices in my home are getting that speed. Only laptop is giving 0.30 mbps.I've formatted my laptop and updated the drivers.
