This article presents an análisis of the FTTR network quality, specifically highlighting the disparities between wired and wireless connections. The author, Benjamin9544, shares their personal experience with FTTR in a domestic setting, noting that their computer host machine connects via Ethernet while other devices connect via WiFi. The author observes varying ping times when using Tailscale to connect to their home in Macau, with times ranging from 160ms when using IPv4 to less than 20ms when using IPv6. In an attempt to resolve the issue, the author tested connecting their host machine via a wired connection with an exit node in Macau, resulting in low ping times but slow network speeds or no connectivity at all. In contrast, mobile devices such as iPads and smartphones, connected via WiFi, experienced no issues, with YouTube loading quickly and speed tests reaching speeds of 260M, approaching the maximum speed limit of 350M at the author's home. As expected, being connected to the same router, wired and wireless connections should not exhibit significant differences in performance. This raises questions about the underlying technical issues and potential solutions to optimize FTTR network quality.
