 Posted: Sun Jan 18, 2015 1:35 am Post subject: iwconfig not showing wireless extensions |
 |
|
Hi all,
First off: I'm new at Gentoo so don't kill me (for now).
I am having a issue with iwconfig since it does not show the wireless extensions for my wireless device.
However, with a combination of wpa_supplicant and dhcpcd I do have a working wireless internet connection.
I have tried a bunch of stuff, but no success. I'll try to list all relevant information below:
My wireless devices:
| Code: | laptop-gentoo ~ # lspci | grep -i net
03:00.0 Network controller: Qualcomm Atheros AR9285 Wireless Network Adapter (PCI-Express) (rev 01)
05:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 06)

Starting with ifconfig:
| Code: | laptop-gentoo ~ # ifconfig

iw shows wireless device.
| Code: | laptop-gentoo ~ # iw wlp3s0 info

iwconfig says it isn't a wireless device.
| Code: | laptop-gentoo ~ # iwconfig
enp5s0 no wireless extensions.
sit0 no wireless extensions.
lo no wireless extensions.
wlp3s0 no wireless extensions. |
Driver does not provide wireless file.
| Code: |

lsmod doesn't show that it's loaded.
| Code: | laptop-gentoo ~ # lsmod

But yet it is running.
| Code: | laptop-gentoo ~ # dmesg | grep ath

My kernel options:

CONFIG_WIRELESS=y
CONFIG_WEXT_CORE=y
CONFIG_WEXT_PROC=y

So, to be clear, I am writing this from my gentoo laptop with a working wireless connection.
The reason I'm so keen on getting the (outdated) iwconfig working is that applications such as conky and i3status tend to use it.
I can't stand looking at 'W: down' while browsing the internet.
Thanks for any help. |

i've had the same issue recently: some (newer) drivers just don't work with iwconfig, only with iw (took me some time to figure that out since "it has always worked" with iwconfig).
if some applications depend on iwconfig then they can't be used with these drivers, i guess.
| Quote: | | lsmod doesn't show that it's loaded |
then it's just not a module, but compiled directly into the kernel. if you configure the drivers as modules it will be shown and you can (un)load as needed.
GOOD LUCK!

Use net-wireless/iw instead. iwconfig is deprecated. So also the WEXT kernel option may be unselected. |

DawgG ... there is a compatibility layer for NL80211 based drivers to support WEXT (which wireless-tools uses exclusively) in the form of CONFIG_CFG80211_WEXT. Enabling this (which, last I checked, isn't by default) should allow iwconfig, iwlist, etc, to function. The OP has this enabled so I'm not sure what is happening in their case ... unless, your "recently" actually means "very recently".
best ... khay |

@khayyam
thx for the hint!
but since i don't have any special needs for iwconfig, iwlist, etc i'm satisfied that it works with iw just as well.

Are you saying I should not try to fix this problem?
Anyone knows anything else I could try? |

SummerIsComing ... I've gone over the info provided above and it doesn't make sense, I see CONFIG_ATH9K=m (from /proc/config.gz ... so, the booted kernel), I see the (ath9k) device renamed by udev, iw/ifconfig shows the interface, yet no module is loaded ... I can't suggest anything because I simply don't know how to interpret what is essentially conflicting data.
Now, when you say "I am writing this from my gentoo laptop with a working wireless connection" you mean the same machine/kernel from which the above info is provided ("laptop-gentoo")? That would seem to be the case because iw shows the channel set to 2462 MHz ... so, something just seems plain wrong with that.

| Thanks khay. I will keep trying things. If I do find a solution, I'll report back. |
