-------------------------+--------------------------------
Reporter: Jeremy Li | Owner: developers
Type: defect | Status: new
Priority: normal | Milestone:
Component: kernel | Version: Chaos Calmer 15.05
Keywords: wifi driver |
-------------------------+--------------------------------
I found the codes that add support for TP-Link TL-WDR6500 v2 in the trunk
branch, and add it to the 15.05 code tree. And it works, at least for some
devices, but the 2.4G wifi does not work(i can see the ssid, but can not
connect to it) on some devices(they are the same board(QCA9561 & QCA9882),
and the hardware version is the same),but the result is different.
I checked some debug info on both kind of devices. on the working devices:
root@OpenWrt:~# cat /sys/kernel/debug/ieee80211/phy1/ath9k/interrupt
RXLP: 775311
RXHP: 0
WATHDOG: 3
RXEOL: 76
RXORN: 0
TX: 143430
TXURN: 0
MIB: 0
RXPHY: 0
RXKCM: 0
SWBA: 705194
BMISS: 0
BNR: 0
CST: 1752
GTT: 1018
TIM: 0
CABEND: 0
DTIMSYNC: 0
DTIM: 0
TSFOOR: 0
MCI: 0
GENTIMER: 0
TOTAL: 1609905
on the not working devices:
root@OpenWrt:~# cat /sys/kernel/debug/ieee80211/phy1/ath9k/interrupt
RXLP: 0
RXHP: 0
WATHDOG: 0
RXEOL: 4
RXORN: 0
TX: 67330
TXURN: 0
MIB: 0
RXPHY: 0
RXKCM: 0
SWBA: 538637
BMISS: 0
BNR: 0

GTT: 0
TIM: 0
CABEND: 0
DTIMSYNC: 0
DTIM: 0
TSFOOR: 0
MCI: 0
GENTIMER: 0
TOTAL: 605971
the difference is that the RXLP is 0 on not working devices.
and there are some difference in the /proc/kmsg when open the ath9k debug
option. the detail will be list in the attachments.
