  • Connection keeps cutting in and out.


Solution:

  1. Restart your device:
    • Power cycle your device by turning it off and on again.
    • This can help refresh the connection and clear any temporary glitches.
  2. Check for IP address conflicts:
    • Ensure two devices aren’t sharing the same IP address.
    • If you notice conflicts, restart the devices or renew their IPs.
  3. Update network drivers:
    • Go to Device Manager > Network adapters > Update driver.
    • An outdated driver can cause connection instability.

    • Move closer to the router or remove objects between the device and the router.
    • Thick walls and electronic interference can weaken Wi-Fi signals.


4) Wi-Fi Not Working

Weak or absent Wi-Fi signals are often due to interference or router glitches. Adjusting the Wi-Fi channel and ensuring devices are within range often resolves the issue.


Symptoms:

  • Devices can’t connect to the Wi-Fi network, or the signal is weak.


Solution:

  • Check physical connections:
    • Ensure the router is plugged in and powered on.
    • Verify all cables (Ethernet, power) are secure.
  • Restart the router:
    • Power off the router for 10 seconds, then power it back on.
    • This can resolve temporary issues or software glitches in the router.
  • Change Wi-Fi channels:
    • Log into the router’s settings and select a different Wi-Fi channel (1, 6, or 11 are best for 2.4 GHz networks).
    • Wi-Fi interference from other networks can cause weak signals.
  • Ensure devices are within range:
    • Move devices closer to the router.
    • Wi-Fi signals weaken with distance or obstructions like walls or furniture.


5) IP Address Conflicts

An IP conflict occurs when two devices are assigned the same IP address. Releasing and renewing IPs or manually assigning them resolves this.


Symptoms:

  • Error messages like “IP address conflict” or “another device is using this IP address.”


Solution:

  1. Release and renew the IP address:
    • Open Command Prompt and type ipconfig /release, then ipconfig /renew.
    • This will force the device to request a new IP address from the router.
  2. Assign static IP addresses:
    • Go to your device’s network settings and assign a manual IP address.
    • Ensure no other devices on your network are using the same IP address.


6) DNS Server Not Responding

DNS issues prevent websites from loading by failing to resolve domain names. Changing the DNS server or clearing the cache fixes these errors.


Symptoms:

  • Unable to load websites, but services like email still work.


Solution:

  1. Change DNS servers:
    • Open your router’s settings and change the DNS to a reliable one, like Google’s (8.8.8.8) or OpenDNS (208.67.222.222).
    • This bypasses your ISP’s DNS server, which may be slow or malfunctioning.
  2. Flush DNS cache:
    • Open Command Prompt and type ipconfig /flushdns.
    • This clears out old or corrupted DNS records that may be causing issues.


7) Limited Connectivity or “Unidentified Network”

This issue arises when a device fails to get an IP address from the router. Resetting settings or renewing the DHCP lease usually fixes it.
Symptoms:

The network status shows “Limited” or “Unidentified Network” with no internet access.


Solution:

  • Reset network settings:
