Introduction

The wireless local area network (WLAN) card, or Wi-Fi card, is an essential component for laptops to establish and maintain wireless connectivity for internet access. The following symptoms can be signs of a failing or faulty Wi-Fi card:

  • Can’t connect to the internet
  • Connected to the router but no internet
  • My Wi-Fi address won’t show up
  • Wi-Fi connection keeps dropping

If your Lenovo ThinkPad T450 is experiencing any of the above symptoms, it may be time to replace the Wi-Fi card in your laptop. When you remove the back cover of the laptop to expose the inner components, the Wi-Fi card is typically fastened onto the motherboard by a single screw. Follow these simple instructions to replace the Wi-Fi card in your device.

    Not to be Captain Semi-Obvious... but can you tell us the model of the wi-fi lan card? I am getting in my possession a t450 with wifi not working.. I have yet to look at machine to see if it is in fact a bad card.. but would like to be able to factor such cost into my purchase. I hope you see this relatively soon, as I have a Top Shelf bottle of ketchup for you if you reply soon!! Thanks
