Good day everyone,
I would like to ask about the file transfer speed using Wifi. It is slower than what I'm expected.
It was recorded about 10MB/s or not greater than 14 MB/s.
I used FTP for transferring a file about 5GB from my laptop to my Samsung phone Galaxy Note 10.
My router is D-Link DIR-842 C1.
I connected to 5Hz for both Laptop and phone. Here is what showing on my router.
FTP invokes many more parameters in the equation, like HDD read speed, flash writing speed.
Moreover transferring between 2 wireless hosts, the speed will be halved, as the laptop needs to send a frame to the access point and then the access point to send it to the phone.
If you want to measure the WiFi throughput connect only one device on the WiFi and run an iperf with a host connected on the wired lan.
Thank you Trendy,
I would like to ask for the command to test using iperf regarding this case. I already installed iperf, but I'm still finding how to use it. Can you please help me!
That's fast (in my opinion), what speed are you seeking?
With the stock firmware, the speed was about 20 to 25 MB/s. But the slow speed is occured when I'm in Openwrt firmware.
Yes, 80 Mbps (or 10 MB/s), or 160 Mbps does seems like a good speed in a real use situation (not knowing any other factors on the channel).
A slight change due to Kernel upgrade (and the new overhead) could be expected. But I would test with one device on wired. Also 320-600 Mbps (or 20-25 MB/s x 2) seems theoretically impossible:
