Bug ID: 252725
Summary: Realtek RTL8821AU/TP-Link T2U Nano: Frequent
disconnects on Intel Tiger Lake
Product: Base System
Version: CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: kern
Assignee: [email protected]
Reporter: [email protected]
When using a Realtek RTL8821AU/TP-Link T2U Nano on a HP Spectre x360 13t-aw200
(TigerLake) running 13-ALPHA1 6483fc224b1, I get frequent disconnections and
resets:
dmesg log:
rtwn0: device timeout
wlan0: link state changed to DOWN
rtwn0: ieee80211_crypto_encap returns NULL.
wlan0: ieee80211_new_state_locked: pending ASSOC -> RUN transition lost
This does not happen on the said Spectre with a CanaKit/Ralink dongle, or the
same TP-Link dongle on an older HP Spectre x360 13-ap0053dx (WhiskeyLake). The
latter case was used with older 13-CURRENT kernels, however.
