Ping Commands

 After using ping commands and traceroute commands, I have learned a lot. I am currently in a place in the world where the internet is not very good. Our options for internet are WiFi (unlimited data use) through an Internet Service Provider and Cell Phone Data. It is nice to even have internet, but the internet infrastructure is not very strong and every storm we have, the connection is either extremely slow or nonexistent. The Cell Phone Data seems to be reliable and quick, but it is more expensive and there are no options for unlimited. After performing a traceroute command and a ping to these various websites, I have determined that the Cell Phone Data is immensely faster than the Wifi. It was fascinating to see the packets transfer from one device to another at measured speeds. The packet transfer times change as well as the places they go. The screenshot below shows the internet speeds are actually pretty fast but as I am writing this, the internet is very slow and some of the hops are taking over 2800ms. The path of the packets is different between domain names because each domain name has different servers in different geographic positions. For me, servers in America are a tiny bit slower than European Servers. These types of commands can be used to find out where the internet issues are located physically. The addresses in the traceroute can pinpoint between which routers or devices there is an issue. This saves time troubleshooting and can allow for a quick fix. The book mentions some good tips about restarting the modem, router, and computer to fix slight issues. I must reset my router about every other day and almost every single time I do, that procedure fixes the connection. This class is actually helping with real world problems and I can appreciate that.
