Comment 0 for bug 1009540

The rtl8180 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.
