An exclamation mark next to the phone with WiFi symbol Android displays indicates that the phone is connected to a WiFi network but cannot access the internet. Here’s how to troubleshoot:

Check the Router: Ensure the router is properly connected to the internet and that all cables are securely plugged in. Restart the router by unplugging it, waiting 30 seconds, and plugging it back in.
Verify Internet Connection: Test the internet connection on other devices connected to the same WiFi network. If other devices also lack internet access, the problem likely lies with the ISP.
IP Address Conflicts: Occasionally, IP address conflicts can prevent internet access. Try renewing the IP address on the Android phone by disconnecting and reconnecting to the WiFi network. You can also try setting a static IP address in your phone’s WiFi settings.
DNS Server Issues: The DNS (Domain Name System) server translates domain names into IP addresses. If the DNS server is not working correctly, it can prevent internet access. Try changing the DNS server in your phone’s WiFi settings to a public DNS server like Google DNS (8.8.8.8 and 8.8.4.4) or Cloudflare DNS (1.1.1.1).
Captive Portals: Some public WiFi networks require you to agree to terms and conditions or log in through a captive portal before granting internet access. Open a web browser and see if you are redirected to a login page.

Intermittent WiFi Connection

If the phone with WiFi symbol Android displays flickers or the connection drops frequently, consider these troubleshooting steps:

Check Signal Strength: Weak signal strength can cause intermittent connections. Move closer to the WiFi router to improve signal strength.
Interference: Wireless interference from other devices (e.g., microwave ovens, Bluetooth devices) can disrupt WiFi signals. Move away from potential sources of interference.
Router Firmware: Outdated router firmware can cause connectivity issues. Check the router manufacturer’s website for firmware updates and install them.
Channel Congestion: WiFi routers operate on different channels. If many routers in the area are using the same channel, it can cause congestion and interference. Use a WiFi analyzer app to identify the least congested channel and configure the router to use that channel.
Network Settings: Resetting the network settings on the Android phone can sometimes resolve intermittent connection issues. This will erase saved WiFi passwords, so make sure you have them handy.

Advanced Troubleshooting Techniques

Checking WiFi Settings on Your Android Phone

Delving into the WiFi settings can reveal potential configuration issues. To access these settings, go to Settings > Network & Internet > Wi-Fi.
