Patience and confidence are the names of the game when troubleshooting a home network, and for beginners, both of those may be in short supply.

That is the advice from Nathan Holmes, Director of Operations at WhyReboot, who himself has been in the networking game for quite some time, having worked with Access Networks prior to his job at WhyReboot, and taught many a novice installer while there.

With many people getting their start in custom installation (or just learning about home networks as a hobby) we asked Holmes to pull from his time as a teacher to offer some tips for beginners when troubleshooting a home network.

Tips for Beginners in Troubleshooting Network Issues

Here are the tips Holmes had to give for beginners in network troubleshooting.

Disconnect Everything on the Network One Device at a Time

When troubleshooting a network, the most effective way to isolate the culprit–whether you’re a beginner or an expert–is to disconnect and replace one device at a time. If the system still does not work with the replacement device, then disconnect that device and put the original device back in the system. Then move on to the next device.

What Happens When Crime Prevention Meets AI (And Why We Can’t Rely on AI Alone)

In an era where crime continues to evolve, relying solely on AI-based solutions proves insufficient in preventing sophisticated threats and false alarms. The webinar will emphasize the paramount importance of human judgment and intuition in tandem with AI technology to create a truly complete security solution. Our session will explore how Deep Sentinel’s revolutionary approach combines the best of both worlds—advanced artificial intelligence and the presence of highly trained human guards. Together, these elements create an unparalleled level of protection for residential and commercial properties alike.

“If you have 20 components in a system and you replace more than one at a time, you will never really know what caused the problem or how you fixed it,” advises Nathan Holmes, technical trainer at Access Networks. “The same logic applies to building a system. Connect one device at a time and test. It is tedious and time-consuming, but if you rush, you will ultimately lose your shirt on labor from mistakes.”

Don’t Doubt Your Networking Knowledge

During troubleshooting training one time, Holmes “tricked” beginners by purposefully including a network switch that was incompatible with the devices necessary to complete the task. In order to connect the Araknis wireless access point, Wattbox power supply and Vivitek surveillance camera, the system required a powered network switch. But Holmes forced the students to come to that conclusion on their own.

“It is very common in this industry for the wrong devices to be spec’ed on to a project. It could be the salesperson’s mistake, but most often it is caused by the homeowner deciding to add more devices to the system than were originally specified,” says Holmes.

Don’t Be Afraid to Call Tech Support

In another troubleshooting test for beginners, Holmes used a network power supply that had subsequently had the default password changed from the time the device was purchased (and thus what was printed in the manual) until the time it was being installed.

“Manufacturers update the default passwords all the time but sometimes don’t update the manual. If you know you are doing everything right, don’t be afraid to call tech support…that’s why they are there,” he says.

Establish a Repeatable Practice for Future Network Installations

“If you establish repeatable processes, you will eventually create a profit buffer for your company on your labor,” Holmes told the students. By that, he means it might take you 90 minutes to do configure a small basic network the first time, and your company might have only billed it for one-hour of labor. They lost money on your labor. But eventually, that same technician might only take 30 minutes to configure that small network, which means you are making profit on that one-hour’s worth of billed labor.
