Ubuntu Networking :: ALFA AWUS036H - Adapter Not Running On Any Channel At All
Dec 8, 2010
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 have Ubuntu 10.04 (32 bits) and a wireless usb adaptor Alfa Network AWUS036H with Chipset Realtek 8187L. After a few minutes connected, the adaptor disconnects and I can't reconnect again. I search this forum but I'm not sure about what to do. Do I need to get and install another driver? I need to use the windows driver?

Works fine in Windows 7 on this PC. It's a 2 week old Dell Studio 1749, with no after market software installed aside from Ubuntu (as a secondary OS). When I plug the USB adapter in, the computer locks up. Only while in Ubuntu though. Not sure what the deal is. Chipset is RealTek RTL8187. The adapter is new, fresh out of the box.

I recently bought the Alfa AWUS036h which uses the Realtek rtl8187 chipset. I am able to load the module and connect to any network, but its almost as soon as I try to load a page the connection drops. It never stays connected for more than 30 seconds. My other computers using the same adapter in the same spot work fine, unfortunately there not running slackware. I've tried compiling the newest stable kernel and checked the rd.inet1.conf settings.

I have Ubuntu 9.10 and I am trying to get my ALFA network adapter to work. It shows a few wireless locations including my brother who lives beside me. He is going to let me use his internet on my laptop. His connection is opened and I can connect to it fine... but no sites load... I've tried about 4 other open networks that I picked up and the same thing... it sometimes loads the first page but then thats it... This is suppose to be the best network adapter on the market for under $100. I have a 5dBi ant and a 2.4ghz 6dBi ant.
Oh yea, I've tired this on two other ubuntu 9.10 desktops and 1 laptop and get the same thing... I am however able to connect to my wireless router and browser the internet... but I will not have internet much longer

i have ALFA AWUS036H 500mw wireless card which uses RTL8187L chipset. Ubuntu 9.04 and 9.10 come with preloaded rtl8187 driver but they DO NOT work for internet surfing. However they do work with aircrack suit for injecting etc. Specific problem is: They only work with really close ranged AP, anything far and you will have random disconnects or inability to connect. So basically its unstable compared to patched driver.
To get this alfa card working for internet access, the only way currently is to use any LInux distro with Kernel 2.6.30 and lower. Starting from Kernel 2.6.31 they have made some changes to net api structure which wont let you patch the driver with the patch available at aircrack website which is normally used to make this driver suitable for internet browsing. Refer to this thread for more info: [URL]... I am currently using backtrack 4 pre final but i was going to install kubuntu 9.04 till i recieved an email from realtek with a new driver that compiles in kernel 2.6.31. I tested it on Kubuntu 9.10 and it compiled fine but i could not make it run. Under NetworkManagement for Kubutnu, the problem is that it keeps asking for WEP key and gives me the message 'wlan4 failed to connect' instantly after i enter the key, so its possible that its not compatible with NetworkManagement. I havent tried it with wicd yet, it may work........

I am using Ubuntu 10.04 64-bit and I purchased a new ALFA AWUS036H wireless card. I would like to know if this "1Watt" wireless card is configured for full power. iwlist wlan0 txpower results:
wlan0 unknown transmit-power information. Current Tx-Power=27 dBm (501 mW). It appears to me that I should be able to increase the power. "iwpriv wlan0 highpower 1" does not work. Do I need to patch the new default driver that comes with Ubuntu 10.04 64-bit with the aircrack one following these directions:[URL]...? Monitor mode and a injection tests seem to work fine with the driver I have installed.

This is wireless adapter: [URL]... USB/Detail.bok I have 2 AWUS036H Wireless USB adapter that uses the RTL8187 Chipset connected to a USB 2.0 Port. It is very slow when I try to go to websites or download anything using Ubuntu 10.04 Lucid Lynx. The max speed I can get out of it is 135 Kilobytes per second when downloading anything. But when I am on Windows I can max out 2.6 Megabytes per second. I have been trying to find a solution but have found none. When I look at the light on the wireless adapter and compare it to what it looks like on both Ubuntu and Windows. It seems that the wireless adapter light is dimmer on Ubuntu. So I was thinking it was txpower set very low. I changed it but no success on changing speed. I am using WPA2-PSK which obviously uses AES. I have also tested it while it is in WEP and when it is Open with no change in speed. Speed results Ubuntu 10.04: Speed results Windows 7: I changed the settings to Megabytes on those speed results.

I have Backtrack4 installed as a dual boot with Vista in my Acer Aspire 5315 laptop. I can connect to my access point with my inbuilt wireless Atheros AR5007EG wireless adapter by starting services/network and WICD. The problem I have is connecting my Alfa network RTL8187 wireless through WICD or wireless assistant. My Alfa network adapter works fine as I have used it with Aircrack-ng in BT4.

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?

I have scoured the web for every bit of information I can find regarding installing the ieee80211 patched driver for the realtek rtl8187, to use an Alfa AWUS036H for packet injection. Error after error after error, I have had no success, and all I can find is other people with the same setup having the same problems.
Assume I have installed Ubuntu 10.10 straight out the box, so no updates have yet been made. Is someone in the know willing to post some step by steps on how to download, install and patch the necessary driver and install necessary software, including precise info on how to blacklist or remove mac80211 version rtl8187.ko in order to replace it with the patched ieee80211 version?
I know there's a tutorial on here somewhere for installing rtl8187 in an older version of Ubuntu, and in that thread, the people with Ubuntu 10.10 all seem to be having the same problems.

I have a Alfa AWUS036NH that I have downloaded the lastest drivers from Alfa. I have read for 3 days straight and tryed so many fixes I cant remember them all. My problem is that it connects then after about 15 minutes the connection degrades and i have to unplug and replug in and then it goes down sooner each time. I have edited the black list and blacklisted all the 2870 chipsets as mine has 3070 chipset. once i edited the blacklist I can no longer boot into linux unless I unplug my Alfa (usb) and then once I am into the UI I can plug it back in but the wirless management client up by the top right of my screen that came with ubuntu no longer sees the card and when I do the show devices command from a terminal it doesn't show the adapter either. I also have a wired eth0 that works and a wireless wlan0 thats an internal Aethros that works. After blacklisting though it no longer shows it's name in the wireless manager but does show the connections. I am getting errors when trying to compile the manufactors drivers. I have renamed the 2 files as per several posts and still errors. I have read it works if you load the intel 2200 drivers. I got the compiler and everything but am missing the ieee80211 wireless what evers to compile and make it work. I am at wits end at what to do now to fix it.

Allright so I installed Ubuntu a week ago, I realized by net is much slower on Ubuntu than on Windows. So I did some Googling and found out I have the wrong drivers.I'm trying to fix it from this link :[URL]When I try to write in Sudo codes into terminal they don't work. They ask for a password, I put mine in and press enter I get the following message :shayan@ubuntu:~$ sudo modprobe rtl8187shayan@ubuntu:~$

Im running Ubuntu 11.04 with alfa awus036nh. I first tried to install drivers from alfa disc for RT3070. Everything seemed to be working but i got the imfamous mon0 channel -1 problem with aireplay-ng. Did some research-downloaded and tried different drivers rt2800 rtl 8170. Bottom line is i dont know what THE F*** im doing. I think i installed three different drivers. Now airodump doesnt show any output. Im going crazy. Is linux designed to make ppl go crazy. Windows is calling me to go back to it. THings shouldnt be this complicated. BTW im on a asus laptop with atheros ar 9285 card in it. a breif explanation of how drivers work in linux . Once again maybe im just putting the cart b4 the horse as im only about 2 weeks fresh into ubuntu.

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 find myself in unfamiliar territory. I am attempting to get a Dell M610 (in an M100e) running Ubuntu 9.1 64bit to talk to a Dell EMC Fibre Channel Array. The Dell has an Emulex card in it and it appears that the driver is loaded OK. What I am not sure on is what to do next! I have the SAN end configured but how do I get my LUN mounted on Ubuntu ?

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

product: PRO/Wireless 2200BG [Calexico2] Network Connection

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.

I'm using Slackware 13 on my laptop, but when I remove the AC power adapter and try to boot slackware my X server doesnt start. I had the same problem with Slackware 12, but I fixed it with adding a line in xorg.conf. Something like this:
Option "PowerAdaptor...." Now I dont remember the exact line... I'm not so sure about this line in xorg.conf.

I have been using Linux for over a month and have gone through several books on it. My weak point in linux is system internals and the kernel, (which I am reading up on now). I am a computer scientist and so I am computer savvy, but have not had much experience until recently with linux. (I was a windows guy, but Ubuntu 10.10 has changed my opinion) I am trying to install drivers for the alfa networks wireless adapter AWUS036H. I followed their online manual and I didn't get very far. After looking at the error messages then I assume it is a kernel issue. Here is the error messages I get when I am trying to make the program:
steven@steven-Satellite-A100:~/Downloads/Software/Wireless_Adapters/AWUS051NH/Drivers/RT2870_LinuxSTA_V2.3.0.0$ sudo make

Is there a way to fix this?

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

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.
