Network Troubleshooting and Installations

Process of elimination is the network troubleshooter’s best friend. Many things can cause network issues but they’re most commonly due to one of these, beginning with the most common to the least common:

  1. Router/firewall/switch functionality – possibly requiring a reboot
  2. Loose cable connection on the desktop
  3. Poor signal strength – if you connect wirelessly and you are more than three walls from the router, your Internet connection could be dropped
  4. Wireless and hard wire conflict on a single PC – users should choose one or the other as using both connection types causes issues
  5. Virus – run a malwarebytes scan. If malicious files are detected, supplement with a second or third scan from a reputable name such as AdwCleaner to make sure all infections are removed
  6. Antivirus software corruption – if no viruses are detected, temporarily disable or possibly uninstall your antivirus to see if this corrects the issue
  7. IP address conflict – make sure DHCP and statically assigned IPs are consistent
  8. DHCP or DNS conflict – make sure there is only one DHCP and one DNS server on your network
  9. Router/firewall/switch functionality – possibly requiring replacement

I’ve personally run into each of these issues in the field. Some of these network troubleshooting issues can be remedied in minutes, others can take much longer. That being said, I keep my troubleshooting process logical and rely heavily on my experience to find the source of the issue as fast as possible. I can also recommend known reliable network equipment. Let me know how I can help.
