How TO **TROUBLESHOOT** A Network By Accident!





TP-Link (TL-SG1016D) Accidental Network Error Discovery!

The other day I saw a used GIGABIT switch for sale on Carousell, Hong Kong's local version of eBay + Amazon.  I bid on it and I won!  Yaay!

When the unit arrived, I did an unboxing video - but switches are pretty boring devices and there's not much material to do a "show and tell" with.  


So, at the suggestion of Mrs. Maker, I also did a "teardown" video where I took the switch apart in search of a moving part (like a fan) to check on, like with a 3COM switch I refurbished almost 10 years ago

No dice.  The TL-SG1016D is a passively cooled device, which means that it has heat sinks and uses airflow and convection to keep itself cool.  Maybe in a future video I'll install a miniature fan, but first I would need to determine that such hackery is needed by using a thermal imaging system (like a FLIR camera).

Anyways, I did my best to bulk up the content by taking the switch apart, putting rubber feet on it and so on...and then ran out of stuff to say...

So I went and put it into service, fully expecting a no-drama situation - only to have a "WTF!" moment when I realized that one of the ports on the switch (PORT 4) was not reporting a Gigabit connection when it should have!




After a little bit of investigation, I found out that the cable in question was not working properly.  The fix was pretty simple.  I swapped out the ethernet cable for a different one.

After that, the link came up at the correct speed:



So what had originally started off as a pretty banal video about a very simple device with no moving parts, no problems and practically zero user experience, I discovered a mis-behaving part of my network that was negatively affecting Mrs. Maker's enjoyment of her computing experience.  

Fixing this problem made me a hero to Mrs. Maker!   Mostly because I somehow magically improved the (perceived) speed of her computer...So...THANKS TP-LINK!


Help a Maker Out?


Did you see anything in this video you want for yourself? If the answer is yes, consider using one of the link(s) below to buy it directly from amazon.com. When you do, I get a small commission that keeps me going!
