+++ This bug was initially created as a clone of Bug #704502 +++ Description of problem: I am unable to switch on the wireless network on network manager. I have tested both Fedora 15 I am currently using a laptop with Dell Inspiron 14 having wireless driver,iwlagn. I am uncertain whether there is a missing kernel module, or if there is some error in the NetworkManager application. Version-Release number of selected component (if applicable): Fedora release 15 (Lovelock) At first, the firmware for the wireless card was missing and I installed it by 'yum install iwl6000g2b-firmware'. By this I was able to get the option to connect to wireless connection. But now I'm unable to turn it on from the network manager. How reproducible: Every time. Steps to Reproduce: 1. Click on NetworkManager 2. Trying to change wireless state from Off to On Actual results: The NetworkManager does not switch and remain turned off Expected results: Activating the wireless network and get a list of available networks Additional info: Following are the additional info as requested by 'jklimes' for the cloned bug. --- Additional comment from jklimes on 2011-05-16 04:18:25 EDT --- 1. your laptop type Dell Inspiron 14R (N4110) 2. lspci -vv | grep -B 12 iwlagn Region 0: Memory at d1704000 (64-bit, non-prefetchable) [size=256] Region 4: I/O ports at efa0 [size=32] Kernel modules: i2c-i801 01:00.0 Network controller: Intel Corporation Device 008a (rev 34) Subsystem: Intel Corporation Device 5325 Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0, Cache Line Size: 64 bytes Interrupt: pin A routed to IRQ 49 Region 0: Memory at d1600000 (64-bit, non-prefetchable) [size=8K] Capabilities: <access denied> Kernel driver in use: iwlagn Kernel modules: iwlagn 3. rfkill list 0: dell-wifi: Wireless LAN Soft blocked: yes Hard blocked: yes 1: phy0: Wireless LAN Soft blocked: no Hard blocked: yes 4. rpm -q kernel kernel-2.6.38.6-26.rc1.fc15.x86_64 5. nm-tool NetworkManager Tool State: connected (global) - Device: wlan0 ---------------------------------------------------------------- Type: 802.11 WiFi Driver: iwlagn State: unavailable Default: no HW Address: AC:72:89:20:E9:46 Capabilities: Wireless Properties WEP Encryption: yes WPA Encryption: yes WPA2 Encryption: yes Wireless Access Points - Device: p9p1 [System p9p1] -------------------------------------------------- Type: Wired Driver: r8169 State: connected Default: yes HW Address: 14:FE:B5:BB:EB:C7 Capabilities: Carrier Detect: yes Speed: 100 Mb/s Wired Properties Carrier: on IPv4 Settings: Address: 192.168.2.5 Prefix: 24 (255.255.255.0) Gateway: 192.168.2.1 DNS: 192.168.2.1 DNS: 172.31.7.197 DNS: 172.31.7.133 By looking at the output of rfkill, it seems the wireless Lan is blocked. Please help. Thanks in advance
rfkill indicates that WiFi is hard switched off. Probably, you should switch a hardware Wifi switch/button on or press a key combination (I think 'F2' or something). Try also # rfkill unblock all and check again with $ rfkill list
I am also experiencing this issue with a 6230 (rev 34) device. rfkill list shows 0: dell-wifi: Wireless LAN Soft blocked: yes Hard blocked: yes 1: dell-bluetooth: Bluetooth Soft blocked: yes Hard blocked: yes (and also a physical adapter, but that's irrelevant) rfkill unblock all does nothing. Hitting Fn-F2 changes Hard blocked: no, but it doesn't seem to allow NetworkManager to function.
When Wi-Fi is blocked either hard or soft, NM can't use it. Stephen, what is the output of 'rfkill list' *after* you enable wireless with Fn-F2. And if something is still blocked, does 'rfkill unblock all' helps? What is your laptop?
I can't explain why, but when I booted this laptop up just now, the wireless is working. Both soft and hard block is "no". For the record, it's a Dell XPS 15 L502X (Sandy-bridge). So I guess I'm in good shape.
This message is a notice that Fedora 15 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 15. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At this time, all open bugs with a Fedora 'version' of '15' have been closed as WONTFIX. (Please note: Our normal process is to give advanced warning of this occurring, but we forgot to do that. A thousand apologies.) Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, feel free to reopen this bug and simply change the 'version' to a later Fedora version. Bug Reporter: Thank you for reporting this issue and we are sorry that we were unable to fix it before Fedora 15 reached 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, you are encouraged to click on "Clone This Bug" (top right of this page) and open it against that version of Fedora. 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
