Description of problem: After updating to kernel 2.6.25.11-97, the WLAN LED is flashing nearly all the time. Up to the previous kernel 2.6.25.10-86 the WLAN LED was only flashing occasionally, when actual data was transported. The constant flashing of the WLAN LED is distracting. It also gives the uncomfortable impression that some data is permanently transmitted to/from the notebook, even when all applications are closed. Version-Release number of selected component (if applicable): kernel 2.6.25.11-97 x86_64 How reproducible: Always Steps to Reproduce: 1. Update to kernel 2.6.25.11-97 2. Connect to a WLAN access point 3. Watch the WLAN LED on the notebook Actual results: The LED is constantly flashing nearly all the time. Expected results: The LED is flashing only on actual data transport. Additional info: It's a Lenovo R61 with iwl3945 driver. When turning off STP at the access point, the situation got a little better. Anyhow booting from the previous kernel 2.6.25.10-86 gave back the previous behavior.
This message is a reminder that Fedora 9 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 9. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '9'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 9's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 9 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
This bug is still present in Fedora 11.
This bug is still present in Fedora 12. When I update kernel to 2.6.32.9-67.fc12.i686.PAE

Still reproducible with Fedora 12 kernel-2.6.32.11-99.fc12.x86_64. BTW: This bug celebrates its 2nd birthday in a few weeks. :(
Then let's put it out of its misery... I'm sorry that you don't like it, but that is working as designed. Wireless networks are a lot more "chatty" than you might expect. And no, the LEDs are not smart enough to differentiate "actual" data from the traffic used to maintain the network.
Thank you for your help, but I think you were closing the bug too early. :) As I reported, the behaviour was allright on the 2.6.25.10-86 kernel, so obviously LEDs were smart enough, but now aren't. Okay, seriously... It seems like a single wireless package triggers the LED to flash a few times. The result is that even a permanent low traffic (like instant messenger heartbeats) causes the LED to flash more or less continuously. The behaviour I expect should be similar to the traffic LED on network switches or LAN ports. A package only triggers a single flash (LED off, LED on) there.
