Dear All.
I hope someone can explain something to me, and hopefully help me find a solution.
I have an Odroid C2 with LibreElec connected to home router via gigabit ethernet cable. One HDD drive for media strorage is connected to Odroid via USB port. Hdd is accesible by smb from home laptop.
My Laptop connects with home network over 5GHz wifi. Laptop with windows 10, wifi adapter is an Intel AC-8265.
The problem is that I can download data from that shared hdd relatively fast (about 280Mbps) but uploading the data to the hdd is a lot slower (20 - 50
Mbps).
Please see attached screenshot from iperf3 when odroid is a client with comparison when it's a server. This test also shows huge dicrepancies between upload and download.
Since I more frequently upload data to the odroid's hdd (photos, recordings etc) I would benefit from higher trasfer rates to the hdd, than from it.
Can someone explain this please and possibly advise?
Things that make no difference:
Changing wifi channels,
Changing laptop wifi adapter drivers,
Changing usb port where hdd is connected
Any help appreciated.
Kind regards
Marcin
