YunCore SR3200: Problems with both radios

For Developers
1

YunCore SR3200 (ar71xx) has problems with both radios (2.4 & 5.8 GHz). They do not operate on high bitrates. It configured as 00-World (any change doesn't help) with Tx-Power: 30 dBm (any change doesn't help) but still works in range of 0-14Mbit/s.

You disabled WMM which effectively disables 11n HT operation. Remove option wmm 0 from both SSIDs and remove the bursting, ff, xr and ar options as well as these only apply to ancient madwifi drivers.

Done.

Speed remains on 20.1Mbps which is arount 15-16Mbps according to Speedtest.net.

Attached TP-Link TL-WR1043N/ND v1, OWRT 15.05.1, to the same network (on totally different channel) with same settings but the maximum output 100mW only (in compare to 200mW of YunCore) works great on maximum of 54Mbps.

I also tried to switch channels with no luck, result remains the same.

Moreover, YunCore with the official OWRT prowided by manufacturer also works great with highest speed.

There should be somethig wrong with drivers or so.

Please, attach full bootlog from your device.

5

This smells like calibration issue.

6

This distance is extremely low. Consider increasing it to something like '100.'

Also, I advise changing your:

  • country setting, and
  • removing the the additional options you've added - as @jow previously mentioned above

This is unclear, what does your router say the speed is?

  • Is there a reason you made these configuration to your radio?
  • If you use a WiFi analyzer app, are there other devices on your channel(s)?
  • How much bandwidth does your ISP give you?
7

As I use Wi-Fi at my flat, 18 meters should me more than enough.

This is necessary because of Tx-Power limitation by country.
As I use it inside building it helps to deliver signal for the whole area.

As already mentioned, done with no improvement.

Literally 20.1Mbps and sometimes it goes to even lower numbers. Never to higher rates.

Please be specific, which ones?

Are there from neighbours but with very low strength. I know how to select the proper channel.
Moreover, as I said, another device (TP-Link, see above) with half of power (100 mW instead of 200 mW) delivers much better performance on the same channel when I switch channels between devices. Yeah, both are not on the same channel, nor adjoin.
And… strength of signal is very high.

100 Mbit full-duplex over fiber. YunCore delivers that full speed on eth ports with no problems. The problem is definitely in radios on on the way.

8

I'm not so sure...counting reflections and "long path propagation." Well, I'm with @robimarko...

Are you running any type of traffic shaping, though???

9

I would first check if OpenWRT partition layout matches the stock one.
It could be that calibration partition is not in the same place or is called different

10

No, I'm not so stupid to report slow speed on throttled device.

I'm aware of:
[ 10.144363] ath10k_pci 0000:00:00.0: Direct firmware load for ath10k/pre-cal-pci-0000:00:00.0.bin failed with error -2

and
[ 10.575026] ath10k_pci 0000:00:00.0: Direct firmware load for ath10k/QCA988X/hw2.0/board-2.bin failed with error -2

13

How to do this check?

14

That's expected, if you look few lines below, firmware was loaded:

[   10.686295] ath10k_pci 0000:00:00.0: board_file api 1 bmi_id N/A crc32 bebc7c08
[   11.890267] ath10k_pci 0000:00:00.0: htt-ver 2.1 wmi-op 5 htt-op 2 cal file max-sta 128 raw 0 hwcrypto 1

Are you able to build a custom image yourself? If yes, please try patch included in this post: XD3200 (QCA9563) slow ath9k/2.4GHz - LNA/PA? - #12 by datacop. I no longer have access to these YunCore devices.

15

Unfortunately I'm not. There is no enough space on the device to setup environment for creating builds.
But if you can create build for this target I will test it.
