Output of 'lspci -vvnn' for D-Link DWL-G520 Rev. B4
Ok, I had overlooked the following section on the ath5k driver page: Notes on supported devices Please note that 001c is an 802.11bg device. As you can see from above the current driver design is for 802.11a, 802.11ab, or 802.11abg. We'll probably need a new device type in the driver for this device to pass only bg initial register writes and baseband gain settings. As you seem to realize, unfortunately the PCI ID alone is insufficient to determine whether or not a given card works with the ath5k driver... No improvement for kernel-2.6.24-0.110.rc5.git4.fc9. On the ath5k development list, a git commit for b/g only cards had been reported, see: https://lists.ath5k.org/pipermail/ath5k-devel/2007-December/000422.html Is it already included in 2.6.24-0.110.rc5.git4.fc9? Yes, it is. I've been following bug 254192 which seems related to this one. My wifi card is a D-Link WNA-2330 I set up my laptop dual boot. One partition has a Fedora 7 system with all updates as of 18 Dec and madwifi installed. On bootup everything seems to work. The other partition has never had madwifi installed, and has the kernel 2.6.23.9-45.fc7 installed. On bootup it creates wlan0, fails at determining IP information for wlan0, and iwlist wlan0 scan returns no scan results. Is this of any interest? Based on a register dump of my D-Link DWL-G520 Rev. B4 adapter, N. Kossifidis has added the missing RF2414A support to the ath5k driver. After building the module [from a private tarball] against kernel 2.6.23.12-99.fc8, I'm now able to scan successfully for APs in my neighbourhood. I do not succeed to associate with the AP yet though, but things are clearly making progress .. I have the same symptoms with a TRENDnet TEW-443PI card and kernel
2.6.23.14-115.fc8.
#lspci -v
Ethernet controller: Atheros Communications, Inc. AR5212 802.11abg NIC (rev 01)
Subsystem: Atheros Communications, Inc. TRENDnet TEW-443PI Wireless PCI
Adapter
Flags: bus master, medium devsel, latency 168, IRQ 10
Memory at 40900000 (32-bit, non-prefetchable) [size=64K]
Capabilities: [44] Power Management version 2
Kernel driver in use: ath5k_pci
Kernel modules: ath5k
Any clue when the changes will make it upstream?
A user with your model has confirmed that scanning works for him now, too, using the private snapshot mentioned in comment #7. However, even for an unencrypted AP, no data was transmitted. This implies that it maybe more than a matter of a simple code commit. A major update is pending but a little patience is needed, see https://lists.ath5k.org/pipermail/ath5k-devel/2008-January/000500.html : "I have a patch ready but i'll post them all together on my next series that 'll addd 2413 support + rf code cleanups/ refactoring (currently we 're having exams and i don't have any time to propertly make a patch series the way i want to)." *** Bug 429658 has been marked as a duplicate of this bug. *** The snapshot provided by N. Kossifidis at: ftp://www.kernel.org/pub/linux/kernel/people/mickflemm not only allows to scan successfully for access points but even provides full connectivity with my D-Link DWL-G520 Rev. B4 !!! Fixed in kernel-2.6.25-0.105.rc5.fc9 which now provides full connectivity as reported in comment #11 for the latest ath5k patch set. |
