Lenovo ThinkPad W700 Wifi
You are better off buying a new wireless USB adapter and just plug it in, than to replace any built-in adapter your laptop may have. The WiFi in your laptop, if so equipped, uses a piece of hardware to send and receive signals to and from your router and modem. A lot of newer wireless adapters are plug-n-play, which means you simply plug it into a USB port and the system will install the drivers automatically. Searching for a new adapter is simple because all you need to know is the operating system that is installed on your Lenovo laptop.
Subtle hints your internal WiFi has very little life left
- The laptop wireless driver shows it as not installed
- Your WiFi in your Lenovo laptop does not connect at all
- The WiFi goes in and out during the day
