changing txpower
With this driver, no matter what we do the output of:
iw dev or iw wlan0 info
is: txpower 12.00 dBm
when trying to set: (after forcing down) iw dev wlan0 set txpower fixed 20mBm or 30mBm, nothing changes.
The makefile has these options:
CONFIG_TXPWR_BY_RATE = y CONFIG_TXPWR_BY_RATE_EN = y CONFIG_TXPWR_LIMIT = y CONFIG_TXPWR_LIMIT_EN = n
But they don't seem to change anything.
Has anyone been able to set the txpower to 20mBm or 30 or something other than 12?
txpower is not implemented in the official driver. https://github.com/RinCat/RTL88x2BU-Linux-Driver/blob/master/os_dep/linux/ioctl_cfg80211.c#L4180
Lucky for you, I just updated to the last official driver I can found, and it "seems" support change TX power. It can be set and read, but I have no way to test if it actually changed TX power.
Use iw wlan0 set txpower fixed 2000 to change to 20.00 dBm.
Compiled and working. Seems it actually sets it on the adapter itself. I went back to the old driver on another OS and it was now 20dbm. Updating the driver definitely changed it from 12 to 20. But this driver DOES let you change it. Thanks so much!
When running hostapd we are seeing: wlan0: interface state UNINITIALIZED->COUNTRY_UPDATE wlan0: interface state COUNTRY_UPDATE->HT_SCAN
Hi, so after running a test with 2 clients overnight we got all these errors hostapd stopped working. Have you seen this before?

Basically thousands of those errors.
No, but the code shows the error is H2C API command timeout. Is the device under heavy load?
At that time no, but sometimes yes. How can we prevent it? Are there any run-time flags or anything we can set? Or how to handle/recover from it? It crashes the driver I think and requires a reboot.
I feel like this wasn't an issue in the older driver. Can you tell me where I can get your 5.6 version and do a comparison test?
https://github.com/RinCat/RTL88x2BU-Linux-Driver/archive/314b662331971b10eb484fbcedb06bf5abfcb211.zip Latest 5.6 version.
The manufacturer also provided me with an updated hostapd/wpa supplicant if that helps.
No ideas, since I have never encountered this bug. You may try unload and load the driver again to see if it reset. hostapd/wpa should be fine.
How about this errors:
RTW: ERROR rtl8822b_c2h_handler_no_io: C2H(9) enqueue FAIL! RTW: [HALMAC] [ALWAYS]shall R reg twice!! RTW: ERROR [HALMAC] [ERR] Dump efuse in suspend
How can we disable btrtl (bluetooth driver for same wireless card) and btusb for that card?
RTW: [HALMAC] [ALWAYS]shall R reg twice!! RTW: ERROR [HALMAC] [ERR] Dump efuse in suspend
is normal. But
RTW: ERROR rtl8822b_c2h_handler_no_io: C2H(9) enqueue FAIL!
is not.
Bluetooth is disabled, or you have anything in /proc/net/rtl88x2bu/wlan0/btcoex?
we can recompile with CONFIG_BT_COEXIST = n instead of yes and try it also...
Any issue setting this in makefile? CONFIG_POWER_SAVING = n
We also set: iw dev wlan0 set power_save off
So today we have the following failure on the latest 5.8 driver:
RTW: WARN _beamforming_leave:
and then it deauth's the wifi device...and no longer allow anything to connect without a reboot.
Set rtw_beamform_cap=0 to disable beamform. But I think you probably crashed the device for some reason.
Make sure it has enough power supply and not overheat.
still getting these errors which break the ap...? any ideas?
[75756.600303] RTW: WARN _beamforming_leave: xx:xx:xx:xx:xx:xx is neither beamforming ee or er!! [75756.600309] RTW: WARN _beamforming_leave: xx:xx:xx:xx:xx:xx is neither beamforming ee or er!!
Maybe the interface disappeared for some reason. It cannot found an interface with the mac address.
Hi, so our adapter is usb 2.0 and no matter what modprobe command comes up it seems to be trying usb 3.0 mode. is there any other way to force usb 2.0 other than during modprobe? such as in the makefile?
