I put vero 4k and Asus router AC87U together, ftp doesn’t work under 5g wifi
We need to focus on the real problem. I don’t think it’s SFTP or FTP but the network.
So this is what I think we need to do next. Use iperf to test your network.
On the 4K:
$ sudo apt install iperf
$ iperf -s
(I renamed the thread to match the real problem)
(I renamed this thread to match the actual problem)
And on your other system (iperf should be available for Mac and Windows) install iperf and then:
iperf -i1 -t60 -cname_or_ip_of_vero
(I renamed the thread to match the real problem)

Those numbers are lower than I’d expect to see. Is your router AC capable? If so, what do those numbers look like?

actually， the asus au87u bandwidth is 2400 ，dont dropped packets
OK, that’s really bad. You should be getting 90+ Mbits/sec.
Is your Vero flat on a table? Try standing it on end, so the bottom of the Vero is facing the router.
How far is the router from the Vero, and are there any walls in between?
ok, now i put 4k beside router,this 5g wifi log, but ftp don’t work

Much better!
FTP or SFTP? I’d strongly recommend that you use SFTP or SCP instead of FTP. Or even better, you should just share via SAMBA or NFS and copy that way.
I test that ftp and sftp work well under 2.4g wifi, but ftp and sftp don’t work under 5g wifi since the signal is better
in addition，i paly movie (high rate and 4k) via smb, after i put Vero 4k beside router ，the video always buffer 5g wifi，but works well under wired
What does ifconfig look like when connected at 5G, and also when connected at 2.4G?
Something in your network settings are different when connecting at 5G I bet.

Nothing jumps out at me there.
Can you copy a file with SCP? This isn’t making a lot of sense right now.
So you can play a movie with SMB, but with buffering with a 4K source, right? How about a regular HD or SD source? You may need to add the buffer settings to advancedsettings.xml
<advancedsettings>
<cache>
<memorysize>157286400</memorysize>
<buffermode>1</buffermode>
<readfactor>4.0</readfactor>
</cache>
</advancedsettings>yes i can copy file to vero 4k under 2.4g with SCP，but it doesn’t work under 5g with SCP， i copy it by command line on my MacBook
this is my advancedsettings.xml
< advancedsettings>
< cache>
< memorysize>90000000< /memorysize>
< buffermode>1< / buffermode>
< readfactor>10.0< / readfactor>
< / cache>
< / advancedsettings>
When you are switching between 2.4 and 5, are you rebooting the Vero? Or just changing the network? Because you have the same MAC address, I wonder if something in the network stack is getting confused when you switch networks. Try switching the Vero to the 5G network, and reboot the Vero and the router.
ok, could you tell the command that refresh vero 4k ip?
Just switch to the 5G network, and reboot the Vero and the router.
i do as you say, not work under 5g wifi
