Hi,
I'm a little confused about the status of the modules for the Realtek
8822BE.
Once, there was r8822be which had some issues, but worked more or less
reliable. Then came rtw88/rtwpci and in my Thinkpad A275 it is hardly
usable. According to the router, a 390Mbit AC connection exists, but
downloads drop to 70-100kb/s. The TX-Bitrate is stuck at 6.5Mbit and the
rx drop misc counter increases nearly every second from time to time -
while being at the same place all the time, 5m away from the router, a
FritzBox 7590.
In contrast to the mainline module, lwfingers module does not have the
TX-Bitrate-stuck issue and the connection drops are more rarely.
I switched to the 4.19 LTS kernel and r8822be gets a 866Mbit AC
connection with 200-300Mbit througput, which is somehow impressive
compared to the 50kbit-40Mbit of rtwpci. In addition, it shows that the
issues seem not to be caused by interferences, as here are only 3 5Ghz
wifis.
Can I do something to improve the situation regarding rtwpci?
Best Regards

Tony, that rtwpci sounds like very confusing name for a rtw88 module,
even I was first confused what driver is that. I think it should be
rtw88_pci or something like that.

True, I can rename it to rtw88_pci. I am also thinking if I should rename
all of the prefixes from "rtw_" to "rtw88_", but that seems to be a huge
patch. I will try to see if this is necessary to do it.

Great, thanks.

Yeah, that's not so important but good to have anyway. I think you
should start with symbols marked with EXPORT_SYMBOL().
