Einleitung
The wireless card is the component responsible for the Wi-Fi connections. If the laptop is experiencing trouble connecting to Wi-Fi networks, it’s most likely that the password is wrong or maybe you’re not authorized to access the Wi-Fi network. If that’s not the case, then it’s probable that the card is not functioning properly, and it can be replaced for the Dell Inspiron 15-5567 using this guide. For more troubleshooting information, please take a look at the troubleshooting page first before replacing the wireless card. You’ll need a Phillips #0 screwdriver, and the blue plastic opening tool. Even though the wireless card replacement is easy, note that the transparent bracket that you’ll take out is relatively easy to lose. It’s an important component of the wireless card, so keep everything organized, and know where everything is.
