Dell XPS L702X Wifi
Buying a wireless adapter is quite easy due to the fact that all you need to know beforehand is the operating system that is installed on your Dell laptop. It is much simpler to buy a common WiFi USB adapter and install it, than it is to replace any type of OEM adapter you might have. Most USB wireless adapters are plug-n-play, which just means that you only need to put the adapter into an available USB port and the OS will handle everything from there. The WiFi in your laptop, if so equipped, uses a piece of hardware in order to talk to your wireless router or modem.
Subtle hints the WiFi adapter should be replaced
- The WiFi adapter driver cannot be installed
- The WiFi adapter on your laptop cannot see the SSID coming from your router
- Your wireless internet connection has trouble connecting all the time
