Description
The rtl8812au driver is glitchy, explained: https://github.com/gordboy/rtl8812au/issues/1
I tested all the drivers I could find on the internet, installed with DKMS and it never worked without glitches for both devices for both kernels 4.9 and 4.14. https://pastebin.com/6erHF6wY
- NETGEAR A6100: RTL8811AU
- TPLink AC1200 Archer T4U: RTL8821AU
The Odroid Wifi module 3 RTL8188CUS on the other side is working wonderfully with a ping of 2ms (max 150) with the in-built kernel driver.
The Odroid WiFi module 4 RT5572N is horribly bad in performances with constant high ping around ~50. With 1 second pings, we get 1 fast ping (20ms) one slow (150ms+) : https://pastebin.com/Rp64npD2
I tested the newest kernel available 4.14.15.103 and it is still present.
Do you have any idea which dongle can be used for 5GHz operation on a/b/g/n/ac standard without that glitch? Should I go for a Qualcomm Atheros based chip?
The lowest latency is the aim but the robustness is the core requirement. (Robotics)
