My Lenovo laptop crashed while I was using Riverside, so I forced a restart with Ctrl+Alt+Delete. Since then, it connects to my Wi-Fi router successfully, but Windows reports "Connected, no Internet." The router and internet connection work normally on every other device in the house. I already performed a Windows Network Reset and restored the system to a restore point from three days earlier, but neither helped. I'm wondering whether the crash left the DNS, TCP/IP, Winsock, or network driver in a bad state. What command-line resets or driver troubleshooting steps should I try next?

A common first step is to open Command Prompt as administrator and run `ipconfig /release`, `ipconfig /renew`, and `ipconfig /flushdns`. You can also follow those with `netsh int ip reset` and `netsh winsock reset`, then restart the laptop.
I tried the release, renew, and flushdns commands, along with the TCP/IP and Winsock resets, and rebooted afterward. They didn’t fix the problem, and the renew command appeared to report that it couldn’t complete.
