#21594: Atheros WNDR3800 - WiFi regression
-----------------------+-------------------------------------------
Reporter: raz123 | Owner: developers
Type: defect | Status: new
Priority: normal | Milestone: Designated Driver (Trunk)
Component: packages | Version: Trunk
Resolution: | Keywords: dma mac beacon r48234 dd wifi
-----------------------+-------------------------------------------
Comment (by raz123):
Tried Designated Driver r49088. Connected devices experience frequent
intermittent hiccups. I'm investigating.
Also: 2.4 Ghz appears to be much less stable than 5 Ghz.
Logs after 32 hours of uptime:
