Slate 7 slower speed than Beryl AX

Routers
1

I just bought new Slate 7 router to replace my Beryl AX, and when using my laptop (which has WiFi 6) speed of copying file from other computer in the network dropped from 90+ MB/s to 60 MB/s. The setup is identical for both routers, both connect at 1200mbps to the laptop (link speed), that other computer is connected to the router via ethernet, but Slate 7 provides lower actual data transfer rate.
Ho do I fix this?

Are you talking about USB read/write speed?

Is your BE3600 using the standard power adapter?

What format is your USB device in?

No, it's actually network speed. My setup is following: server <-> router <-> laptop. Server is connected to the router via 1 Gbit Ethernet, laptop - via WiFi. In both cases WiFi connection is 5 Ghz, 102.11ax mode, 1200Mbps. Laptop has WiFi 6 adapter. Router is connected to 100W PD adapter.

When I use Beryl AX as a router, and copy large file (10GB or so) from the server to the laptop, file is copied at about 90-100 MB/s, though when I swap the router to Slate 7 (having same settings as Beryl AX), copying speed drops to 60 MB/s.

What I also noticed is following. When I use iperf3 to check speed, on Slate 7 I get quite low numbers:

~> iperf3 -c 192.168.8.1 -R
Reverse mode, remote host 192.168.8.1 is sending
[ ID] Interval           Transfer     Bitrate
[  5]   0.00-1.00   sec  20.8 MBytes   174 Mbits/sec
[  5]   1.00-2.00   sec  27.6 MBytes   232 Mbits/sec
[  5]   2.00-3.01   sec  29.1 MBytes   243 Mbits/sec
[  5]   3.01-4.00   sec  30.2 MBytes   254 Mbits/sec

I can get slightly faster speeds if I run it in parallel (pasting only SUM values here for brevity):

~> iperf3 -c 192.168.8.1 -R -P 4
Reverse mode, remote host 192.168.8.1 is sending
[ ID] Interval           Transfer     Bitrate
[SUM]   0.00-1.00   sec  36.0 MBytes   301 Mbits/sec
[SUM]   1.00-2.00   sec  46.1 MBytes   387 Mbits/sec
[SUM]   2.00-3.01   sec  47.0 MBytes   393 Mbits/sec
[SUM]   3.01-4.01   sec  49.9 MBytes   418 Mbits/sec

Though with Beryl AX I get faster speeds even with one connection:

~> iperf3 -c 192.168.8.1 -R
Reverse mode, remote host 192.168.8.1 is sending
[ ID] Interval           Transfer     Bitrate
[  5]   0.00-1.00   sec  58.6 MBytes   491 Mbits/sec
[  5]   1.00-2.00   sec  73.2 MBytes   614 Mbits/sec
[  5]   2.00-3.01   sec  75.6 MBytes   632 Mbits/sec
[  5]   3.01-4.00   sec  75.4 MBytes   635 Mbits/sec

Can you connect to BE3600 to test again?
During the test, collect the following information when the laptop is connected to the router's WiFi speed test:

  1. cat /etc/config/wireless
  2. wlanconfig wlan1 list //Execute this 5 times
  3. apstats -i wifi1 -r //Execute this 5 times

If it is convenient, you can also connect to MT3000 to test and collect information

  1. cat /etc/config/wireless

Send the collected information to us for inspection

Also,What is the model of your laptop's Wi-Fi network card?

Sent output of mentioned commands to support@gl-inet.com with topic "Slate 7 slower speed than Beryl AX". During copying file for collecting these data speed was around 60-80 MB/s.

My WiFi adapter is "MediaTek Wi-Fi 6 MT7921 Wireless LAN Card" (Asus TUF Gaming A16 laptop).

Update from email communication:

The thing appeared to be that Slate 7 had "DE" as country code, and Beryl AX had "US", and power for different country codes is different. After I set Slate 7 country code to "US", file copy speed became 90-110 MB/s.
