Fedora Networking :: Missing Channel 12, 13 On Wifi?
May 14, 2010
I'm using wifi "usb card" from airlive with zd1211 driver in Fedora 12 OS. And I cannot access channel 12 and 13. Perhaps for US restrictions. But in EU are allowed. Any idea how to enable them?
iw phy told me the card has 14 channels width but last 3 are disabled.
I tried "iw reg set EU" but "iw reg get" still return me "Country:98"
Also set env. variable COUNTRY=SK and execute crda returns me: Failed to set regulatory domain: -22
in dmesg I can see the regulatory domain is first set to EU but when zd1211 is loaded it is set to US

I ought to understand the radio aspects of wifi better than I do. That said, is there a bad-good-best choice for wifi access point channel number? How does one select a channel number systematically (scientifically) rather than trial and error?

I'm trying to crack my wep password just for kicks, but I keep running into the same error. When I try to use airplay-ng for the packet injection, it always gives me the error " wlan0 is on channel -1, but the AP uses channel 6". I've tried setting wlan0 to channel 6 manually, but that doesn't help. I spent a while searching for a solution, but it seemed like each page had a different, usually highly complex solution, that still doesn't work. I have the most recent drivers for my wireless card, and it meets all the requirements. So, is there any solution to this that will actually work?

The wifi adapter doesn't work. The system tray icon says there is a wifi adapter present, but next to it: device not ready (firmware missing).

I tried to implement the solution given at: [URL] on a Dell Inspiron 1525 laptop, running Ubuntu 11.04. However, I still can't connect to wifi.
I can see that the files were extracted inside /lib/firmware/ (I see a b43 and a b43 legacy folder).
The lspci -vnn | grep 14e4 returns:
Code:

On my previous release *cough* if inenslave was needed, bonding instructions didn't work through aggregation did.
cat /etc/network/interfaces
auto lo
iface lo inet loopback
auto bond0
iface bond0 inet static
address 192.168.1.149
netmask 255.255.255.0
gateway 192.168.1.1
dns-nameservers 127.0.0.1
broadcast 192.128.1.255
post-up ifenslave bond0 eth0 eth1
pre-down ifenslave -d bond0 eth0 eth1
#auto wlan0
#iface wlan0 inet dhcp
#netmask 255.255.255.0
#wpa-conf /etc/wpa_supplicant.conf
For some reason the unmentioned former disto, I could not get wireless networking under this configuration and a simple wlan0 interface, in case either cable were to sever it would retain a wireless. The bonding was done for speed, and I believe I can't get faster than mode=4.

PC seems to run fine in single channel mode but monitor reports no input in dual channel mode and memtest86+ lists from 1-3 errors per pass in single channel mode. Motherboard (Gigabyte P43T-ES3G) can't be set for the 1.65 volts required by the RAM (2x2 of OCZ3P1333LV4GK PC3 10666). The mobo voltage choices are 1.6 or 1.7 volts. I have tried both and increased the MCH voltage from 1.1 v to 1.2 v, but so far can't get it to run in dual channel mode at all and single channel mode seems to run fine but I still get errors in memtest86+. Also tried optimized Bios settings and loosened memory timings (from 7-7-7-16 to 8-8-8-27 and tRFC 60 to 70) and reset Command Rate from 0 to 2. CPU is Core 2 Quad @ 2.4 Ghz, PSU is rated at 400 watts, Video card is Gigabyte GT220.

Thinking about building a new system, with 4GB of DDR3 RAM. I am just wondering, which would you prefer: Dual-channel DDR3 or Quad-channel DDR3? Does one have better speed performance over another? Will one way keep your system cooler?

I just installed Fedora 15 on my HP mini 210-1000, everything is working fine except my wifi is not up. It says firmware missing. How do i fix this problem? Previously I used to have Ubuntu 11.04 on it and wifi worked fine, but I need Fedora as i am using .rpm based applications. So please assist me in getting my Wifi up! lscpi gives this:
Code:

*edit* sorry, found a solution in another post on the forum : [URL]...

i just installed ubuntu 10.04 on my computer, and tried to airodump, but noticed that its stuck on 11th channel, when i specified only channel 6 during scan, it gave me hosts from channel 6 and 11, but then i ran aireplay-ng and it runs on 11th channel as well, even when i put my card into monitor mode with a specific channel option. btw my chipset is AR9285 with ath9k driver. everything worked in backtrack. i also tried to reinstall aircrack which did not work.

I'm relatively new to Ubuntu, and have just installed 10.04 on a toshiba portege M100 laptop. Having got over the intel video chipset problems I tried to connect to my WLAN. Network manager would not connect. I tried switching to WPA, WEP and no encryption. No effect I still could not connect. I also noticed that network manager can find other APs much more quickly than mine.Haveing done some searching I tried removing network manager and installed wicd. Was good at finding the AP but reported it as operatingon channel 0. Still would not connect. I tried changing the AP channel to 6, suddenly everyting worked. I switched back to network manager (wicd got in a tangle over hidden networks). Still works.
Having scoured the web for help I found reference to 10.04 kernel suporting US channels. and that I should create a file /etc/modprobe.d/cfg80211, containing "options cfg80211 ieee80211_regdom=EU". I have tried this and it doesnt have any effect. I have noted that there are numerous variants of this advised by different people.Whilst at home I can operate my AP n a US channel, when I am on the move I cannot. I would like to get this working if at all possible.For info the wireless adaptor reported is:
*-network:1

What is the quickest and the most elegant way to implement the following scheme:On my computer I have two browsers and two internet channels:
1. Ethernet cable internet
2. USB 3g modem/.
When I execute the first browser it uses only the cable internet and the second one uses the USB modem.

I am trying to audit my wireless router due to someone in the neighbourhood hacking it, and have run into a few problems. When I run airodump-ng, everything works fine. However, when I try to get the .csv file and run "airodump-ng -w test --channel 6 --bssid ---------- mon1" (obviously with my the mac address of my AP instead of x's) I get this:
CH 6 ][ Elapsed: 4 s ][ 2011-02-02 17:48 ][ fixed channel mon1: -1 ] The problem is the [ fixed channel mon1: -1 ], because when I go to the next step to try to force a handshake, it says:
18:00:34 Waiting for beacon frame (BSSID:-----------) on channel -1
18:00:34 mon1 is on channel -1, but the AP uses channel 6
I have scoured the Internet for answers, and have seen several people with the same problem, but no solutions that work for me. I think it may have something to do with the driver. I really do apologise if this has been answered properly several times, but none of the solutions seem to be working in my case.

ok so the router works in windows and i know the config details of it.i can see other wifi access points in the area but not my one. i have tried joining it as a "hidden network" to no avail.is there any reason why fedora would not detect my own wifi when it detects substantially weaker signals instead??

My laptop has an internal wireless device and a button to turn it on/off, but since it has bad reception I use an external USB wireless adapter.The problem is that if I turn the internal wireless device off using the button, it also turns the USB wireless adapter off.Is there anyway to use the killswitch (the button) only for the internal wireless device?This only started to happen in Ubuntu 10.04.

I have only had a few weeks worth of experience with linux, so I'm probably considered a newbie at this but I felt like giving it a shot. I just configured my new Toshiba Satellite A505-S6969 to jaunty. Most of the transition is going well but I'm stuck with a few issues, one of which is getting my wifi to work. Right now I'm working off of an ethernet cable.spci returns

I have just completed the installation of 11.2 on a older HP Pavillon dv5115nr. Finally got everything working except for the Broadcom wireless. I have updated the firmware and I can see the AP. I have been using yast to configure the wlan device but one of the last steps it trys to perform is install smpppd. Even when hooked up via eth0 it can't find this program.

I have an old PowerBook G4 that I would like to use as a 'dummy' computer for learning wireless penetration (WEP/WPA attacks) more effectively. I had been using a wireless router, but I gave it away I can use Mac OS X to share an ethernet connection over wifi, but this is _very_ un-configurable. You get two options only, WEP and a key-length. So, I would like to install someway to make this wireless connection more configurable.

I work for a firm of solicitors as the IT guy and I have been asked to assess the security of our network. I have recently bought an ALFA AWUS036H USB wireless adapter to help test the wireless networks. We have a few old devices that only run WEP, which I know from the start is bad. I'm trying to use the adapter with aircack. I issue the command:
[code]...
Now I set the adapter to channel 11 using airmon but running iwlist mon0 channel says the adapter is not running on any channel at all. Has anyone else experienced simular issues, and if so how was this resolved?

I just setup a new LAMP server (CentOS 5.5 x86_64) box with channel bonding on NetXtreme II BCM5709 Gigabit Ethernet (IBM x3650 M3). The problem is I wasn't able to connect to this server when I'm in different VLAN's. This server also unable to ping different VLAN's. But everything works fine when I transact in the same VLAN.Here's the config:
Datacenter VLAN = 9
Firewall = Disabled
SELinux = Disabled

I can use Ubuntu with my onboard wireless in my IBM Lenovo Laptop but it doesn't work here and in other linux distro's I have tried I need to do a lot of code manipulation with the help of experts on the forums telling me what to do. I want to install Fedora 14 and maybe even try other Distro's as they come out without needing to be a Linux expert. So I want to go down to Best Buy a couple miles down the road and buy a USB WIFI Wireless thing.
