Both my desktop (running Windows Subsystem for Linux) and raspberry pi 3 connect to router via WiFi.
Download speed from internet on desktop is decent :
~/tmp$ wget https://cdimage.debian.org/debian-cd/current/amd64/iso-dvd/debian-10.2.0-amd64-DVD-1.iso debian-10.2.0-amd64-D 7%[=> ] 287.30M `11.5MB/s` eta 4m 51s
Download (with no other major network activities going on, of course) speed from internet on rasp pi is more than 10 times slower :
pi:/data/tmp$ wget https://cdimage.debian.org/debian-cd/current/amd64/iso-dvd/debian-10.2.0-amd64-DVD-1.iso debian-10.2.0-amd64-DVD- 2%[ ] 95.29M `846KB/s` eta 78m 3s
scp between the two is even slower :
~/tmp$ scp rasp:tmp/debian-10.2.0-amd64-DVD-1.iso ./ debian-10.2.0-amd64-DVD-1.iso 46% 16MB `218.5KB/s` 01:29 ETA
What could have caused problem of speed on rasp pi? How can I go about troubeshooting the problem ?
sudo iwconfig wlan0 power off. Any improvement?
