NRT Information & How-To

What problems does NRT typically fix?

DNS failures, gateway timeouts, captive portal issues, expired DHCP leases, misconfigured adapters, broken Winsock providers, incorrect firewall rules, and name-resolution conflicts on local networks.

Will this change my Wi-Fi password or SSID?

No. NRT does not modify saved Wi-Fi profiles or router settings. It resets Windows networking components and adapters, not your wireless credentials.

Can I run it without admin rights?

NRT requires administrator privileges to reset core networking components. If UAC prompts you, click Yes to continue.
