Orbi limiting Raspberry Pi Bandwidth
Hi! Im experiencing a really weird issue with my Orbi system. I have latest firmware on my router and satellites (2.5.1.8). My following installation looks like that: - Nokia fiber modem -> Orbi RB...
I did more tests on speedtest.net and notice that my Pi 4B starts out at "full speed" for about 10 seconds (above the 200mbs I pay for), and then the speed falls off sharply and ends up quite a bit less, but still in the neighborhood of 100mbs. My Windows computer does not exhibit this phenomenon. It stays at a pretty constant rate throughout the test. Android phone & tablet the same.
I struggle to comprehend how the Pi could be treated "differently" by the Orbi from Windows and Android devices. The Pi does respond to heat by dropping the clock rate. I am not confident how to measure for that effect while doing a speed test.
I did install Kodi, but "nothing happened" when I started it from the graphic desktop. Maybe it senses there is no HDMI connection on my "headless" Pi?
There are numerous posts on the forum questioning the Orbi's ability to deliver "full speed". Orbi was submitted to the FCC back in 2016, when 100mb speeds were rare, and I do not remember anyone offering gigabit to residential customers. Perhaps another test is to connect a computer to the switch and test speed with it. Does it achieve higher speed than the Pi? (Mine did.)
Sorry not to be much help.
Found a way to observe Pi cpu speed, and looks like that is "not it."
watch -n 5 vcgencmd measure_temp
where n is the number of seconds between observations. (I used 2). My Pi was at 49c when idle and "climbed" to 52c doing speedtest.net (55c for Firefox). The Pi 4B does not throttle clock speed until the CPU temperature goes over 70c. I cannot measure GPU temperature since my Pi is "headless".
