But if connects to 2.5g LAN port, speed is normal for wired connection (1800/900), but the upload is unexpectedly slow in just ~200 for wireless connection:
All of the above were tested in the same environment, cable connects to 2.5g WAN port of Flint2, and the distance between the devices and the router remained unchanged. The wireless devices are iPhone 15 pro max and OnePlus 10Pro, result are almost the same.
I think the problem is not related with the ISP, modem and the cables, may I know what should I do so that the upload speed under wifi could reach the expected speed in around 900? Or this is a nature for Flint2 because of the bandwidth?
Don't benchmark WAN over Wi-Fi. Use Ethernet. The radios in the client devices have such staggeringly different quality between manufacturers it's almost a joke to rely on any of their advertised specs.
Once you have your baseline then start troubleshooting Wi-Fi. I suspect it may be but think it's too early to call any sort of 'bug'. You'll want to bench the Wi-Fi to the AP, not the WAN, first. See the below script to locally hosting OpenSpeedTest if you don't care for iperf3.
Well, that's better than nothing but the stated negotiated link speed (2.5 Gbps) doesn't guarantee the same when it comes to throughout (1.9 Gbps) as you just demonstrated. That benchmark might be even better with a proper Intel 2.5 or 5 GbE NIC & Cat 6 cable.
@bruce : Do you have a benchmarks for what the 'best case' bi-directional Wi-Fi rate would look like? What has GL.iNet documented in their testing?
It does not help... No matter switched off acceleration or using software/hardware acceleration, upload speed remains below 300mb/s under wifi, if connected to 2.5G LAN port of the ISP modem.. Very strange....
MT6000 WAN connects to the 2.5G LAN port of ISP modem
MT6000 wireless clients, UL speed abnormal in the Internet direction (such as speedtest.net)
LAN - WLAN and 1G WAN - WLAN are no problem, but only 2.5 WAN - WLAN has exceptions.
I suspect it's a 2.5G compatibility issue, but not very sure.
You have a 2.5G wired network card, right? How many speeds can you get by directly connecting to ISP modem 2.5G LAN?
Is there any other ISP modem that connects MT6000 to 2.5G port, is UL speed normal? Or, if there is a PC with a 2.5G network card, you can build an OpenSpeedTest Server on PC and connects to the MT6000 WAN?
