Recently, I changed my internet service to a new provider. These guys promised some decent bandwidth at a good price.
After getting it installed, nerd-proofed, and monitored, all looked good.
That is until I had a remote training class to teach over WebEx – then the audio issues began. (Of course! Why do these issues always KNOW?!?! Right when you need the connection the most – boom!)
Every 10-15 minutes or so the audio would drop for about 5 seconds. The students could still see my screen, but the audio was clearly having issues. Fortunately, I could call in using my cell and finish up the class with no further problems.
As much as I wanted to blame WebEx, I knew that it was no small coincidence that I had just changed my internet service. Alas, this time it looked like it really was the network! Time to crack out the tools and troubleshoot.
