Testing Wi-Fi performance on a Librem 5 Birch, using the
speedtest command from the
speedtest-cli package, I get roughly the following:
Download: 32 Mbit/s
Upload: 3.6 Mbit/s
That’s the best I get, having the phone is placed really close to the Wi-Fi router.
For comparison, on my laptop I get over 200 Mbit/s down and about 50 Mbit/s up, and on the PinePhone I get about 40 Mbit/s both up and down.
According to https://puri.sm/products/librem-5/ the Wi-Fi hardware is supposed to be “Redpine Signals RS9116: 802.11 abgn 2.4GHz/5GHz” and
journalctl shows the following:
redpine_91x: ================================================ redpine_91x: ================ RSI Version Info ============== redpine_91x: ================================================ redpine_91x: FW Version : 184.108.40.206 redpine_91x: Driver Version : RS9116.NB0.NL.PURISM.LNX.1.3 redpine_91x: Operating mode : 13 [Wi-Fi STA + BT DUAL] redpine_91x: ================================================
wifi-nl80211: (wlan0): using nl80211 for WiFi device control
Is the fairly limited upload speed (about 3.6 Mbit/s) to be expected given the Wi-Fi hardware in the Librem 5, or is it something that could be improved by software or configuration changes?
