My Wi-Fi keeps disconnecting
Spotty wireless connections can be a puzzler. Is it your computer? Your router? Your ISP? Try a few things before calling your Internet service provider.
Windows Network Diagnostics may not always solve your problem, but it will usually point you in the right direction.
Confirm that your computer is within range of your wireless router. Weak signals mean weak connections. Next, make sure your PC’s wireless card has the latest drivers. Try letting Windows troubleshoot for you by right-clicking the Wi-Fi icon in the taskbar and selecting Troubleshoot problems.
