Fedora 10 Atheros 5007EG was working now broken

There seems to have been a flurry of updates recently.
Somewhere along the way my wireless broke (I've been plugged in to the local lan so I'm not sure what broke it, but it did work).

My current kernel is
output from lspci -nn is
02:00.0 Ethernet controller [0200]: Atheros Communications Inc. AR242x 802.11abg Wireless PCI Express Adapter [168c:001c] (rev 01)
This web page http://home.roadrunner.com/~computer...hwireless.html discribes the chip as Atheros 5007EG. The kernel defaults to ath5k module.

In dmesg it shows:
ath5k_pci 0000:02:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16
ath5k_pci 0000:02:00.0: setting latency timer to 64
ath5k_pci 0000:02:00.0: registered as 'phy0'
ath5k phy0: Support for RF2425 is under development.
phy0: Selected rate control algorithm 'pid'
ath5k phy0: Atheros AR2425 chip found (MAC: 0xe2, PHY: 0x70)
ath5k phy0: gain calibration timeout (2412MHz)
ath5k phy0: unable to reset hardware: -11

the last two lines repeat.

I did try moving back to the previous kernel /vmlinuz-, but that didn't help

I get the same info in dmesg

If I run iwlist wlan0 scan it doesn't find any wireless hubs.

I did try madwifi by blacklisting ath5k and running modprobe ath_pci

I ran ifconfig wlan0 up
iwlist wlan0 scan
No hubs were found (not normal for my neighborhood, should find at least 5 besides my own).

dmesg shows
ath_pci 0000:02:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16
ath_pci 0000:02:00.0: setting latency timer to 64
MadWifi: ath_attach: Switching rfkill capability off.
wifi0: Atheros AR2425 chip found (MAC 14.2, PHY SChip 7.0, Radio 10.2)
ath_pci: wifi0: Atheros 5424/2424: mem=0xfdff0000, irq=16
udev: renamed network interface ath0 to wlan0

Note: that was after a reboot.

Can anyone help me troubleshoot this?


Quick note at the top to say powering down the laptop resolved the problem

I haven't been able to duplicate your issue. My guess is that you might have turned off a hardware switch. (For example, on my Aspire 4720z there's a button that turns it on and off, unfortunately, it's not a switch that's in one position or another. simply a button that's pressed.)

If using MadWifi, the card is probably called ath0, rather than wlan0. (That's not a definite, but is usually the case.)

Make sure that whichever one you're using, (ath_pci or ath5k) that you've blacklisted the other one.

Make sure that the module is definitely loaded (whichever you use)

lsmod |grep ath

power cycle fixed it

On the Averatec, the hardware transmitter control is a button at the top with some Icon I haven't figured out yet.

I did try that. That was my initial barrier to getting wifi to work.

What did remedy the problem I think was powering down the laptop. I had rebooted numerous times, but in this case a power down was needed to reset the chip.

Thanks for the suggestion, it led me down the right road.

I have exactly the same problem with you. same wireless card. same fedora10! do you solve that problem?

I have XP and Fedora 10 both in my laptop. Recently I find my Network Manager didn't show any AP, not by updating or other "things", the problem just occur suddenly, just "suddenly". when I entered the windows I found my wireless didn't work either! In fact wireless did work well in fedora several minute ago.

Lightbulb Re: Fedora 10 Atheros 5007EG was working now broken

I was getting some days now similar error messages on my Fedora 16,

May 9 23:19:59 loft kernel: [188617.065908] ath5k phy0: gain calibration timeout (2452MHz)
May 9 23:20:00 loft kernel: [188617.531234] ath5k phy0: gain calibration timeout (2457MHz)
May 9 23:20:01 loft kernel: [188618.918127] net_ratelimit: 2 callbacks suppressed
May 9 23:20:01 loft kernel: [188618.918131] ath5k phy0: gain calibration timeout (2472MHz)
May 9 23:20:02 loft kernel: [188619.379969] ath5k phy0: gain calibration timeout (2462MHz)
May 9 23:21:56 loft kernel: [188733.347585] ath5k phy0: gain calibration timeout (2412MHz)
and what I did and worked was as root:

rmmod ath5k

At the moment I don't use wifi but ethernet. When I will want to use wifi on my laptop I suppose or I will do a reboot or ( first ) I will try to load ath5k module first

Thanks for adding a 'fix' on the thread, but since the last post was 3 years ago, hopefully the problem's solved long since.
