[Bug 260761] Re: [ath5k] Atheros wireless chipset AR5212 is incorrectly identified as AR2414

As per Ubuntu question:

I also had a similar confusion regarding what wifi chipset I have based
on the results of dmesg vs. lspci/lshw:

dmesg | grep Atheros
[ 10.131682] ath5k phy0: Atheros AR2425 chip found

lspci -nn | grep Atheros
05:00.0 Ethernet controller [0200]: Atheros Communications Inc. AR5001 Wireless Network Adapter [168c:001c] (rev 01)

lshw | grep Network
                product: AR5001 Wireless Network Adapter

I came to the conclusion then that dmesg queries the radio, while lshw &
lspci poll system architecture, but I cannot prove it 100%.

I've updated to the newest kernel:

uname -a
Linux name-laptop 2.6.32-24-generic #39-Ubuntu SMP Wed Jul 28 06:07:29 UTC 2010 i686 GNU/Linux

and now the results of:

dmesg | grep Atheros

are nothing, and:

dmesg | ath5k phy0

produces a lot of entries of:

ath5k phy0: unsupported jumbo

part of a known issue, which can cause performance problems:

Hope that helps!
