Nighthawk AX2400 WiFi 6 Router Changes are not saved If the router does not save the changes that you make in the router web interface, do the following: • When entering configuration settings, always click the Apply button before moving to another page or tab, or your changes are lost. • Click the Refresh or Reload button in the web browser. It is possible that the changes occurred, but the old settings might be in the web browser's cache. Troubleshoot WiFi connectivity If you are experiencing trouble connecting over WiFi to the router, try to isolate the problem: • Does the WiFi device or computer that you are using find your WiFi network? If not, check the WiFi LED on the router. If it is off, you can press the WiFi On/Off button on the router to turn the router WiFi radios back on. If you disabled the router's SSID broadcast, then your WiFi network is hidden and does not display in your WiFi client's scanning list. (By default, SSID broadcast is enabled.) • Does your WiFi device support the security that you are using for your WiFi network (WPA, WPA2, or WPA3)? • If you want to view the WiFi settings for the router, use an Ethernet cable to connect a computer to a LAN port on the router. Then log in to the router, and select BASIC > Wireless. Note: Be sure to click the Apply button if you change settings. If your WiFi device finds your network but the signal strength is weak, check these conditions: • Is your router too far from your computer or too close? Place your computer near the router but at least 6 feet (1.8 meters) away and see whether the signal strength improves. • Are objects between the router and your computer blocking the WiFi signal?
