Description Jonathan Underwood 2012-02-01 09:05:37 UTC 
Description of problem:
I have a Samsung netbook with built in wireless:

09:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev 05)
	Subsystem: Samsung Electronics Co Ltd Device c0a8
	Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+ FastB2B- DisINTx+
	Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR+ <PERR- INTx-
	Latency: 0, Cache Line Size: 32 bytes
	Interrupt: pin A routed to IRQ 46
	Region 0: I/O ports at 2000 [size=256]
	Region 2: Memory at f050c000 (64-bit, prefetchable) [size=4K]
	Region 4: Memory at f0508000 (64-bit, prefetchable) [size=16K]
	Capabilities: <access denied>
	Kernel driver in use: r8169
	Kernel modules: r8169


With kernel 3.2.2 wireless associates with an AP just fine, but after a few seconds to a few minutes the connection drops. NetworkManager still thinks the link is up, nothing appears in dmesg, but the link is dead. Restarting NetworkManager.service restarts the connection, but after a few seconds it dies again in the same way. Reverting to kernel 3.1.6-1 fixes the problem.

Version-Release number of selected component (if applicable):
kernel-3.2.2-1.fc16.x86_64

How reproducible:
Everytime

That lspci info is for an ethernet card. :-)  Can you attach the full lspci (or 'lspci -n') output?

Created attachment 558869 [details]
lspci output
Comment 3 Jonathan Underwood 2012-02-01 16:27:49 UTC 
Not enough coffee, sorry. It's a:


05:00.0 Network controller: Intel Corporation Centrino Wireless-N 130 (rev 34)

so, iwlwifi and friends.

OK, this now looks like a duplicate of BZ 785239, closing as such.
