I need to compile backprots-20131206 into ath10k device driver

Angela — Sun, 05 Jan 2014 20:13:11 -0500

Hi , there

I need to compile source code backports-20131206 into wireless AP device driver as ath10k I used

make clean
make defconfig-ath10k
make

but I found there are no ath.ko mac80211.ko ath9k.ko ath10k_core.ko rt2x00lib.ko

rt2x00mmio.ko rt2x00pci.ko rt2800lib.ko rt2800pci.ko

These are device driver for ath10k, how & where can I use the source code to compile

into ath10k for these device driver for wireless AP.

Thanks

How does linux identify / recognize w wireless network?

dontcare — Wed, 04 May 2011 12:04:28 -0400

I am wondering how linux does recognize a previously used WLAN? Is this done using the BSSID of the access point, using its name (SSID), using, both or maybe something different?

Thanks for any hint :-)

IP Address

What is the command (Linux Mint Julia) to discover the IP Address of a computer connected to a wireless router?

backtrack4 ipw2100 module not being loaded for intel pro wireless b lan

rfelsburg — Tue, 19 Apr 2011 02:10:35 -0400

I can't get my wireless card to be used/assigned under backtrack4. I know it works I've used it on other backtrack installs.

Everything seems to point to backtrack recognizing/seeing it, but it's not recognizing the eth1/wlan0/ath0 interface when I try to set it up.

ThoughtS?

Connecting to a wireless network which uses wpa-psk encryption using Backtrack distro

rfelsburg — Tue, 19 Apr 2011 00:11:28 -0400

PROBLEM

I was having a problem setting up wpa_supplicant on backtrack4.

My wireless point uses wpa-psk.

In /etc/network/interfaces:


root@bt:/usr/bin# cat /etc/network/interfaces
auto lo
iface lo inet loopback

#auto eth0
#iface eth0 inet dhcp

auto eth1
iface eth1 inet dhcp
pre-up wpa_supplicant -B -Dwext -i eth1 -c /etc/wpa_supplicant/wpa_supplicant.conf # you might change these bold parameters to suit your wireless card and interface.
post-down killall -q wpa_supplicant

#auto eth2
#iface eth2 inet dhcp
#
#auto ath0
#iface ath0 inet dhcp
#
#auto wlan0
#iface wlan0 inet dhcp

Everything I read said to use wpa_passphrase like below, and delete the commented lines:


root@bt:/usr/bin# wpa_passphrase My_ssid My_ssid_key
network={
        ssid="My_ssid"
        psk=e8a2c6fb04c3537ec1ea7c027b78f96fba46bc5497503dfe0aa2510844e82ce9
}

however this failed miserably with my setup.

Ideas?

Connecting to internet with a wireless router

Elad Lending — Sat, 26 Mar 2011 19:45:10 -0400

Need to find the *.inf file that I need in order to install the driver that supports the D-Link DSL 2650U wireless router. I've already installed the ndisgtk package, so I have the windows wireless drivers directory in the system area. But I don't understand the bit about the inf file, nor how to search for it. Thank you in advance.

Connecting to internet with a wireless router

Elad Lending — Sat, 26 Mar 2011 11:31:06 -0400

So yesterday I used a USB stick to boot up to Ubuntu for the first time. I can connect to the internet with a cable, but when I try to use the same device in wireless mode, I cannot connect. My wireless router security code is 64 bit, but Ubuntu, under the security dialog box apparently only recognizes 128 bit security codes. Is there a way to log on other than redefining the security code of the wireless router?

WiFi not working

slothcheetah — Tue, 24 Aug 2010 11:02:34 -0400

I'm running Debian Lenny on a Toshiba Satellite A200.

It has a builtin Atheros AR242x 802.11abg Wireless PCI express adapter.

The modules that are automatically loaded to drive this are:

ath ath5k

When using kernel 2.6.32 in a wireless hotspot /proc/net/wireless does not even exist. When using kernel 2.6.24 it exists but has no entries.

I don't know where to go to from here. Can anyone help? (The WIFI switch at bottom of notebook is on).

Finding wireless cards

oldgamer — Fri, 06 Aug 2010 12:07:41 -0400

I am looking for a wireless card for my Linux laptop (not too happy with my Broadcom adapter) is there a list of wireless adapters that don't have a binary blob as a main part of their operation and can go into promiscuous mode?

gnome network manager versus /etc/network/interfaces

Matyas — Wed, 21 Jul 2010 14:19:24 -0400

I need some troubleshooting help with a wireless network problem.

I can connect wirelessly using /etc/network/interfaces. ifup wlan0 gets an address via dhcp and all works well. However, I have to click and disable the network manager trying to connect in order for this to work.

If I let gnome network manager connect, it does not succeed. I am getting in daemon.log: NetworkManager: Device 'wlan0' IP6 addrconf timed out or failed.

Interestingly, gnome network manager succeeds in connecting to public networks in coffee shops. This makes me think something is not properly set up at my home router.

Any suggestions? Thanks!

Intel 4965 WiFi refuses to connect to open, unauth AP

Bolster — Mon, 05 Jul 2010 17:10:56 -0400

I have an intel card that refuses to connect to a completely open AP; Win7 has no problem on the same machine, and the machine has no problem connecting to other, secured, AP's. The Access point itself is a Netgear, and the specific wifi care is a intel 4965.

Syslog pickes up a lot of disconnect reason=6 events (see attached) which implies that the AP gave up waiting for authentication, but there is no authentication!

I've been looking for answers on this for a while

Packet sniffing software for wireless networks

Chris Stewart — Thu, 01 Jul 2010 04:05:21 -0400

I'm interested in learning more about security and I'd really like to run tests against my network here at home to see just what is accessible by modern software. What readily available packages are out there that I can run against my network to see what's being exposed, quite likely without my knowledge?

random wireless disconnections (lucid lynx)

dr. Hannibal Lecter — Wed, 09 Jun 2010 11:18:47 -0400

I'm using Ubuntu 10.04 and I'm having problems with my wireless connection. It simply stops working randomly.

I thought the cause might be a number of connections or something like that, but it's not. Sometimes it stops working while you're off doing something unrelated to the network.

Also, once it stops working, I'm unable to connect anymore until I reboot the machine. Some say it might be a problem with NetworkManager, but I can't use the recommended wicd because it won't even connect (it seems like hidden SSID + wep bothers wicd).

I'd also like to note that I have a windows PC connected to the same router and it never drops a connection like that, so there's obviously nothing wrong with the router.

Any hints would be helpful. I'd like to drop NM altogether if possible, but I'm not aware of any good alternative.

sudo iwlist scan got me a large list of available networks, I'm assuming you don't need it if that's the expected output :)

Edit 2:

No dice! :( My "solution" in the answers below didn't work, in fact it made everything worse, disconnections every few seconds. dmesg said this:

[ 1170.188961] wlan0: deauthenticating from XXXXXX by local choice (reason=3)

I have no idea what it means, but it sure as hell wasn't by MY local choice!

For now I've reverted to NetworkManager and the funny thing is that is seems more stable than before(?). Possibly due to WEP->WPA switch, but I can't be sure..

Any ideas?

DEBIAN 5.04 - Ralink RT73 can see wireless but cannot connect to WEP

SteveG — Mon, 31 May 2010 11:20:48 -0400

I am puzzled as to why my computer MSI notebook which uses the Ralink RT73 drivers cannot connect to my WEP network even though it can see my network and other networks?

All other distros like Ubuntu (and variants), FEDORA 13, Linuxmint 9, PCLinuxOS can easily connect to my WEP network.

Is this because of Debian's outdated kernel?

Hoping for a quick and newbie-friendly fix.

sudo modprobe wl? Root issue? x86 64-bit

techie.brandon — Wed, 19 May 2010 14:38:11 -0400

I'm using ubuntu 9.10 w/ ndiswrapper as wireless driver. After each reboot I am forced to run the command 'sudo modprobe wl', however I am not certain what I lack that it is not detecting the wireless device automatically. I could certainly add some commands in the .profile shell script to run this automatically but I feel like there is a larger issue just under the surface which needs addressed.

Sometimes after lots of downloading the wireless connection seems to die, not that it looses connectivity via the gui or that disconnecting and reconnecting make any difference. To get a good wireless connection again I have to reboot the machine and re-enter 'sudo modprobe wl'.

Anyone have thoughts?
