Wi-Fi and Internet Connectivity Troubleshooting Guide

Step 1: Basic Checks

1. Check Wi-Fi Switch and Airplane Mode

   • Ensure Wi-Fi is enabled on your device and Airplane Mode is turned off.

2. Restart Device and Router

   • Restarting can often resolve connectivity issues. Turn off your device, wait for 30 seconds, and restart.

   • For the router, unplug it, wait 30 seconds, and plug it back in. Wait until all indicator lights are stable before reconnecting.

Step 2: Check Network Cables and Connections

1. Ethernet Cable

   • If you’re using a wired connection, check if the Ethernet cable is securely connected to both the computer and router.

2. Router and Modem Connections

   • Make sure all cables are properly plugged into the correct ports on both your router and modem.

Step 3: Check Internet Status

1. Check Internet Service Provider (ISP)

   • Visit your ISP’s status page (using mobile data, if needed) to see if there’s an ongoing outage.

   • Alternatively, contact your ISP for support if the outage isn't posted online.

2. Try Another Device

   • Connect another device to the Wi-Fi network to see if it’s experiencing the same issue.

   • If other devices are connected but one device isn’t, the problem might be specific to that device.

Step 4: Network Settings on Your Device

1. Forget and Reconnect to Wi-Fi Network

   • Go to Wi-Fi settings, select your network, and choose “Forget.” Then reconnect by entering the Wi-Fi password again.

2. Check IP Settings

   • Ensure your device is set to obtain an IP address automatically.

   • On Windows, go to Settings > Network & Internet > Wi-Fi > Properties and make sure IP assignment is set to Automatic (DHCP).

3. DNS Settings

   • Try changing your DNS to a public DNS server (e.g., Google’s DNS: 8.8.8.8 and 8.8.4.4) to see if this improves connectivity.

Step 5: Signal Strength and Interference

1. Location of Router

   • Make sure the router is in a central location, ideally elevated and free from obstructions. Avoid placing it near walls or metal objects.

2. Check for Interference

   • Other devices like microwaves, cordless phones, or Bluetooth devices can interfere with Wi-Fi signals. Try moving your device away from these electronics.

3. Wi-Fi Extender or Booster

   • If you’re in a large office or have thick walls, consider using a Wi-Fi extender or booster to strengthen the signal.

Step 6: Troubleshoot on Windows

1. Run Windows Network Troubleshooter

   • Go to Settings > Network & Internet > Status, then select Network Troubleshooter.

   • Follow the steps provided to detect and resolve issues.

2. Reset Network

   • On Windows, go to Settings > Network & Internet > Status and click on Network reset. This will reinstall network adapters and reset settings to default.

Step 7: Update Drivers and Firmware

1. Update Network Drivers

   • Go to Device Manager > Network Adapters. Right-click on your Wi-Fi adapter and select Update Driver.

2. Router Firmware Update

   • Check the router’s user manual or ISP website for firmware updates. Follow instructions to ensure you’re on the latest firmware.

Step 8: Advanced Options

1. Check Router Settings

   • Access your router settings by entering the IP address (usually 192.168.1.1 or 192.168.0.1) into a browser.

   • Log in with the credentials provided by the ISP and review network settings for any issues.

2. Change Wi-Fi Channel

   • Some routers let you change the Wi-Fi channel to reduce interference. Experiment with channels (1, 6, or 11 are standard) and test connectivity.

Step 9: Contact IT Support

1. Escalate the Issue

   • If you’ve tried these steps and still have no connectivity, contact your company’s IT support for assistance.

   • Provide details of all steps you’ve tried so far to help them diagnose the issue faster.
