Anker USB C Hub 555 and Ethernet port

I do not intend this site to be the product review site. I actually search my own site to be just a memo pad for daily use.

Having said that, I ran into Amazon not letting me to write the review of Anker’s USB-C hub. I think I’ve written a review before, and I wanted to update my findings about it, and I cannot get to my own product review.

Anker USB-C 555 hub

I’ve been using this hub for quite some time. As a matter of fact, I used to have 2 of them. It works as you’d expect. Everything works as advertised, except one weakness.

The ethernet port sucks. On hot summer day, it seems to overheat and stops working. It’s rare this happens but if you hook up a 4k monitor, USB-C power PD, all of USB ports used, the adapter heats up enough to stop working.

The other ethernet port issue I found is that, it cannot do full gigabit. It caps out around 330Mbit/s. I have another Anker hub of different type and I swapped between 2 Ethernet ports, and one works full gigabit and this one goes up to 330Mbit/s. IOW, this is real apple-to-apple comparison. The benchmarking is done by iperf3.
In real world use, it’s rare that you need full gigabit speed but it shows the Ethernet port is a weakpoint of this hub.
