(in-progress) Connecting to 2Ghz Huawei AX3 yields 5Ghz-ish connection speed and vice versa #30

Closed nikty closed 2 years ago

nikty commented 3 years ago

Strange problems here when using ASUS USB-AC68 to connect to Huawei AX3 router. When connected to 2Ghz network, the speed of connection is actualy that of 5Ghz connection (tested with iperf). Other devices (like phones) and also the same USB adapter plugged into Windows 10 host connect just fine, the result is correct speed for both frequencies.

The Linux is:

Linux debian 4.19.0-16-amd64 #1 SMP Debian 4.19.181-1 (2021-03-19) x86_64 GNU/Linux

Connection shows 2Ghz:

@nikty

It is good to meet you. This is interesting. This is the first time I have seen someone report that their network connection is too fast.

We need to confirm what is going on. Try turning the 5GHz off in the wifi router so that the 2GHZ radio is the only one on. Then do a test. Then do the same with only the 5GHz radio on. Let's see what we get.

FYI: I may be slow to respond over the next few weeks as I am busy.

5GHz off

I turned off 5GHz and restarted router both from web interface and by unplugging it from the wall. The settings are as follows. Iperf:

I was wrong about speed of connection with Windows 10 host.

The tests above give for Win10/Driver 1030.38.0712.2019

5 Ghz is certainly slower than I would expect.

Let's see what the following shows:

morrownr commented 3 years ago

Okay, I see something that would explain a lot of what you are seeing.

rtw_switch_usb_mode:0

This setting needs to be 1. In the driver directory run $ sudo ./edit-options.sh

You were in usb 2 mode. These Realtek drivers are like a standard transmission. You can pretty much max out 2.4 GHz wifi with usb 2 but 5 GHz wifi gets limited seriously.

Let me know what you see now.

I also have adapter with 8812au chipset, tests like above give 118 / 142 / 163 for modes 0/1/2.

BTW, my system doesn't have USB 3.0.

nikty commented 3 years ago

The results seemed random, I moved away from the router (~3-4 m) and did this test:

Repeated for 8812au also (see below). 8814au doesn't even hit 100Mbit/s.

I see. Good job testing. USB 2 is limited to around 480 Mb/s so iperf3 could show up to around 240 Mb/s in a perfect world. So I guess the question is why are we not getting close to that 240 Mb/s? The small amount of retries tends to make me think you have a solid connection so what could be causing the difference in speed? A lot of things but the only things different in your tests appear to be different chipsets with different drivers.

My experience working on both the 8812au and 8814au drivers tells me that the 8812au driver is a MUCH better driver. In fact, the 8812au driver is better than any of the other 4 Realtek drivers that are maintained here. Why? I really have no idea but the versions of the drivers here are the most recent versions from Realtek that have worked their way to the public.

You may just have to play with various settings to see if anything makes a difference. I'm not a fan of letting a wifi router decide what to do so if it were me, I would look at checking the congestion so as to set a channel for both bands. Have I seen lower speeds in managed mode between the 8812au and 8814au? Yes. Nothing new there. The 8814au driver is just not a very good driver. I've been trying to find ways to get updated code from Realtek, if it exist, but have not had luck. I'm not a fan of how Realtek does its driver support. I wish we had good in-kernel drivers but we don't. That is one reason that I push folks that are asking what to buy to look at Mediatek based adapters.

@morrownr Many thanks for your support and comments!

I'm going to stop investigating this for now, but if anything interesting comes up, I'll update the ticket.

Hi @nikty I been following this conversation and just want to add the following. I was gonna say that it could be that the antennas of the ASUS USB-AC68 may not be optimised for the 5Ghz spectrum. Yes, far fetched - I am aware. Unfortunately you cannot replace them, as it seems when looking at the device. So I googled for other iperf3 tests using this device and I found this asus-usb-ac68-wifi-test. Unfortunately only windows driver tests, but they reflect hardware capabilities nonetheless. You are using your device in STA mode (client connecting to an access point) plugged into a usb2 port. In you testing, as far as I can tell, you have been running your iperf3 in client mode on on the computer where the AC68 is plugged into. When running iperf3 the way you did, you have been testing the uplink (data flowing AC68 --> iperf3sever). This is TX. iperf3 -c 192.168.3.113 -t 60 -R would test the downlink (AC68 <--- iperf3server). This is RX. The device in USB2 mode uses more receive channels/antennas (Not quite sure.). Downlink speeds should be higher. From iper3 man page:

Normally,  the test data is sent from the client to the server, and measures the upload speed of the client.
Measuring the download speed from the server can be done by specifying the -R flag on the client.
This causes data to be sent from the  server  to the client.

              iperf3 -c iperf3.example.com -p 5202 -R

So maybe try testing in both directions. Or is that what you did, because you sent each iperf block twice?

I ran the 4 tests on a 1 core cpu laptop using a 8814au plugged into USB2 simulating a 1G file upload and download on 2.4Gz and 5Ghz with default 8814au.conf:

In 5Gz, the downlink maxes out the USB2. I also noticed on 5Ghz, the data sending (TRx) of the my device is a lot more flackier/unstable on lager files, but 2.ghz seems to fine. But that could be my antennas (I can change them). hope this helps.

Hi @abroenni

Your comment is quite insightful!

So maybe try testing in both directions. Or is that what you did, because you sent each iperf block twice?

No, I only did TX test, because its instability and speed initially triggered me. RX does indeed has higher speeds.
