Experience with TL-WR844N
A home network at the office

It is a very good day today. Finally, I can connect all available nodes to the router T-Link TL-WR844N . The nodes are PC all-in- one, Intel NUC Mini PC, Synology NAS, Raspberry Pi, and digital oscilloscop with ethernet port.

Since I am not a tech-guy for networking, it can be considered as achievement for me. All but one are with wired connection, while the first is with wireless connection. The reason for the first is simple, it is located a little bit far away compared to the others and I do not have currently a network cable for such distance, while for the others there are cables from previous activities.

The lights and sounds are very entertaining. It gives a comfortable atmosphere for those who love such stuffs.

It takes about nearly a week to connect all since some of them are previously set up at home with static IP address. And when I want to change it to dynamic IP address, login to them are required. Remote access is impossible due to different subnet. Now it is 192.168.0.x, while it was 192.168.137.x previously. I do not quite remember why I have chosen the old values.

After short search it is related to a Windows service. Since Windows 7, the 192.168.137.x subnet has been used by default for the ICS (Internet Connection Sharing). It was the Intel NUC that was used to share the internet connection from smartphone.

There is still an unfinished work. Today I realize that the OS used in Raspberry Pi nodes 3 and 2 are using nmcli for network manager. As I tried to fix the node 4, I installed ifupwon via apt-get since there wasn’t /etc/dhcpcd.conf nor /etc/network/interfaces. I must uninstall the ifupdown. Perhaps next week.

Another homework is the scope that has dns 192.168.0.1 but with gateway 192.168.0.14, which can not be changed. The IP address 192.168.0.x can be pinged, but there is no other connection allowed.

The dream is to create a program that can control all nodes and get information from all nodes, where each acts as endpoint producing data from different simulation.
