Bug Description
The rtl8180 linux kernel driver (/lib/modules/
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.

Andres Riancho, thank you for reporting this and helping make Ubuntu better. Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http:// cdimage. ubuntu. com/daily/ current/ . If the issue remains, please run the following command in the development release from a Terminal (Applications- >Accessories- >Terminal) . It will automatically gather and attach updated debug information to this report.
apport-collect -p linux <replace- with-bug- number>
Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https:/ /wiki.ubuntu. com/KernelMainl ineBuilds . Once you've tested the upstream kernel, please remove the 'needs- upstream- testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs- upstream- testing' text.
If this bug is fixed in the mainline kernel, please add the following tag 'kernel- fixed-upstream' .
If the mainline kernel does not fix this bug, please add the tag: 'kernel- bug-exists- upstream' .
If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel- unable- to-test- upstream' .
Please let us know your results. Thanks in advance.
