Description Michael 2024-02-26 12:50:31 UTC

No TX power on TP-LINK TL-WN8200ND(UN) v3
driver rtl8xxxu (rtl8192eu)

Device is detected and shown by iw, but it does not transmit (no tx power).
Scan list remains empty:
$ sudo iw dev wlp48s0f4u2u3 scan
$ 

Tested on 2 different device to make sure it is not a hardware fault.

Looks like a problem with the init tables, because the device is a hig power device.

In detail (dmesg, iw dev, iw list):

Comment 1 Michael 2024-02-26 13:53:20 UTC

Some additional information:
The device is a high power device.
Setting general "priv->hi_pa = 1;" in rtl8xxxu_8192e.c solve some problems (not all, which makes me suspect that something is missing in the init table).
I did this just for testing purposes, because it breaks entire compatibility with the low tx power devices.

Comment 2 Michael 2024-03-02 13:33:08 UTC

Some cosmetics:

The device is commented as TP-Link TL-WN8200ND V2:

/* TP-Link TL-WN8200ND V2 */
{USB_DEVICE_AND_INTERFACE_INFO(0x2357, 0x0126, 0xff, 0xff, 0xff),
	.driver_info = (unsigned long)&rtl8192eu_fops},

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu_core.c?h=v6.8-rc6#n7967


It should be a TP-Link TL-WN8200ND V3
