Dear Linux-Wireless,
Some time ago a bug was reported
https://bugzilla.kernel.org/show_bug.cgi?id=202943 related to
rtl8192ee, the essence of which is high ping latency (even to the
access point) without downloading something. If you generate a network
load with a background download or just ping -i 0.001 -s 512.... the
latency stabilizes and stays low.
I tested my TP-Link TL-WN881ND v2 adapters (I got two of them in my
PCs plugged in different motherboards (ASUS and MSI)) and the problem
still persists in kernel 5.2.6 (archlinux current default). Just to
mention, I tested with different module options and also two available
firmwares I found (rtlwifi/rtl8192eefw.bin and
rtlwifi/rtl8192eefw_new.bin).
Would you please take some time to look at the bug? I can provide any
additional information needed.
Please let me know if we can make rtl8192ee driver better.

Best regards,
Sergey Kharitonov
