Title:
10ec:8185 rtl8180 driver unstable with RTL-8185 IEEE 802.11a/b/g
Wireless LAN
Status in linux package in Ubuntu:
Confirmed
Bug description:
The rtl8180 linux kernel driver
(/lib/modules/3.2.0-23-generic/kernel/drivers/net/wireless/rtl818x/rtl8180/rtl8180.ko)
works fine for a while, then slows down, finally disconnects from the
wireless access point and after some seconds reconnects again. This
happens to me with the following network card:
03:05.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8185 IEEE
802.11a/b/g Wireless LAN Controller (rev 20)
Subsystem: Realtek Semiconductor Co., Ltd. RTL-8185 IEEE 802.11a/b/g
Wireless LAN Controller
Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV+ VGASnoop- ParErr-
Stepping- SERR+ FastB2B- DisINTx-
Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort-
<MAbort- >SERR- <PERR- INTx-
Latency: 64 (8000ns min, 16000ns max), Cache Line Size: 64 bytes
Interrupt: pin A routed to IRQ 20
Region 0: I/O ports at e800 [size=256]
Region 1: Memory at febffc00 (32-bit, non-prefetchable) [size=1K]
Capabilities: <access denied>
Kernel driver in use: rtl8180
Kernel modules: rtl8180
Might be useful for the driver maintainer to know that at some point I
had two of these network cards connected and it was almost impossible
to connect to any network. When I disconnected one of them it was
possible to send/receive packets but at slow speeds and with
disconnects every 2 to 5 minutes.
The ubuntu-bug tool should have caught this, but I'm using
"3.2.0-24-generic #39-Ubuntu SMP Mon May 21 16:52:17 UTC 2012 x86_64
x86_64 x86_64 GNU/Linux".
Blacklisting rtl8180 and trying to load rtl8187.ko and r8187se.ko did
not solve the issue since those modules did not create the wlan0
interface I was hoping; and lshw showed the hardware as unclaimed.
Trying to compile the driver from Realtek was very difficult since
they don't provide it for the latest kernel.
If there is anything I can do to help solve the bug with rtl8180,
please let me know. I'm willing to send more information, test
patches, recompile stuff, etc.
