How I found my lost network packets

59 minutes

Today Gerhard shares the entire story behind his lost packets. He is talking with Drew Marshall, director at Trunk Networks and No One Internet, a Cloud Services Provider & ISP based in Sussex, UK.

Gerhard’s Vodafone ISP gateway was losing packets, and recording some of the previous episodes used to be challenging as his internet connection would cut out up to 10 seconds at a time, multiple times per recording session. He was convinced that his Unifi Dream Machine Pro was not the issue. Drew helped Gerhard realise that it actually was. Not only has Gerhard’s DNS latency improved by 3x, but he can now fail-over between two WAN connections. And because nothing beats a real-world experiment, you can guess what is coming in this episode 😉

You will find latency & packet loss graphs, speed test runs, and a few other interestings in the show notes. We hope that they inspire you to setup a better home network. Most importantly, may you find your humble & brilliant Drew.
