| Post subject: | R5A30.1: Issue with WLAN card... kernel config? |
Summary: - I have performed an upgrade to R5A30.1 - The old wireless card does not associate anymore - A new wireless card compatible with madwifi has trouble associating, and when it does, traffic doesn't seem to go anywhere - The same hardware setup works flawlessly under a stock Knoppix 4.02 live CD Log: - Machine has been running under R4V4 for a while. Figured it was time for an upgrade - Did an upgrade to preserve /myth partition, but config files from backup caused many-o messes. So I renamed the backup file so that the upgrade wouldn't find it. Re-installed (with upgrade option). - Can't get the wireless card to work. It worked for months under R4V4, after cutomization to get it going (ndiswrapper, etc...) - Tried getting it to work for a while (ndiswrapper, acx100), then figured it was maybe caused by the switch to 2.6 kernel. - Changed the card to a Netgeat WG311T, said to be supported by Madwifi (atheros chipset) - Downloaded, installed, configured latest madwifi drivers Current situation: - The card will "sometimes" associate properly (with an AP that is about 3 feet away). When it does, reported connection speed is lousy. - I have noticed that bringing up eth0 will trigger ath0 to associate about 5 seconds later. I don't understand at all why that is. - I then bring eth0 down and try to ping the gateway with ath0, but it can't connect. - Everything *seems* to be working fine. Logs look ok, config looks ok, etc. - The same hardware setup in the same spot works flawlessly under a stock Knoppix 4.02 live CD. The card associates right away, connection speed is 54M, connectivity is here. - I just can't figure it out. It annoys me. I need help. My questions: - Is this a kernel problem? Is the kernel somehow misconfigured (explaining the weird behaviour). I have tried rebuilding it from the sources included, but no luck. Are there some secret config options that need to be enabled? - Is someone actually running a WLAN with Atheros chipset under R5A30.1? - What should I do next, short of starting from scratch with a Sarge netinstall CD? Log file and such: Code: iwconfig:

Following up on my own thread... Someone managed to get an atheros-based card working, so it's probably not a kernel issue (http://mysettopbox.tv/phpBB2/viewtopic.php?t=7935) but I reinstalled from scratch with a Debian 3.1 CD, and everything works well, so it doesn't seem to be my hardware. Bottom line: I have no clue. |

Hi Saruman, Have you made any progress? I've just bought a netgear router (WGT624) and network card also netgear (WG311T) and the router side looks good and is set up ok. My mobo in my Mythboxen is NF7 v2 and I've disabled the onboard LAN in the BIOS. I was under the impression it should just detect the card. But not so far. Any more info would be good. btw, thanks for the thread link. That's useful. I had already googled Netgear WG311T and Linux and I got lots of hits. haven't had time to investigate fully, but this looks interesting http://www.packetpro.com/~peterson/linux-netgear_wg311t_pci.html In my initial glance I noticed they refer to "ath0" which I assume is atheros chipset, which means the drivers are there if the thread you listed is correct. Anyway, I'll be trying to get this sorted over the next couple of days. Regards Chris |

Well, as I mentioned, everything works now, using the madwifi drivers. The thing that really stomped me was the fact that I didn't get any errors, problems, etc... but the network connectivity just wasn't happening, or intermittently with very strange patterns. So, again, I don't know what it was. I just couldn't figure out where to start to fix it, so I just reinstalled from scratch (I had wanted to do it anyway someday). A few comments 1) I installed a 2.4.27 kernel, not a 2.6. Maybe that's the difference. 2) Installing from scratch took a long time, and quite some skill. Good thing I had prior experience with MythTV and Linux...: so stick with KnoppMyth, it's the best solution! 3) I will test with a later release when I get a chance (but it requires taking apart my box so it might not happen right away) |
