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
