Wifi packet injection?
I was wondering if the new late 2011 MBA had packet injection ability on it's wifi device.
Does anyone know if the wifi driver with Lion allows this?
I was thinking of buying a MBA 11 inch for on the go surfing and work related solutions.
Perhaps the Nexus has a better antenna or the way you held it could have maintained a better line of sight to the wifi accesspoint? Wifi is 'polarized' so you can sometimes get better (or worse) reception by rotating the antenna through 90º.
It's also possible that the router was too busy when you tried the Mac & iPhone but then was less busy when you tried the Nexus.
Interference could be another reason (portable phones, microwaves, other radio transmitting devices can potentially interfere).
Being too close to an accesspoint (or another transmitting client) can also cause trouble.
Wifi networks can also be configured to 'channel hop' to try to get better signal to noise ratio, this means you may have used different channels on the different devices and may not be comparing like to like. It could also have been another neighboring accesspoint that decided to move away from that channel that helped the Nexus speed up.
It's tough to say, the only real way to test accurately is to have control of the accesspoint so you can control how many clients are connected.
For what it's worth there are a few wifi graphing apps on Android that can indicate how many other networks are around you… (there are also free ones IIRC).

I'd disable wifi on the other devices and try one device at a time & move around to see if one part of the room has better reception.

Wifi packet loss after upgrading to 10.7.4
After upgrading all three macs (mb pro, mb air, imac) in the house to 10.7.4 they all experience wifi packet loss. I ping to the local router. I have connected to a multitude of wireless routers with similar result.
But here is strong evidence that is a the OS X software problem. I am running linux inside of vmware fusion. I have run the exact same ping commands simultaneously in (1) mac and (2) vmware linux. The linux ping experiences zero packet loss, not even a single packet. The mac at its best will lose 1% packets, but can increase beyond that.
We are suffering from slow internet in our corrent location as it is, and this has a noticable impact on our performance. I am a bit afraid to upgrade to Mountain Lion for fear it may be even worse.
Any thoughts?Your
com.apple.systempreferences.plist
file is likely corrupt in your
(use the Finder > Go > Go To folder and paste & Go)
~/Library/Preferences
folder, Trash the flle you can (may be two of them, one is a lock file) and reboot.
Reset your system preferences again.
Also see OnyX here: It has a plist checker for corruption

I have bcm4311 which is supported. Looked over here here and here and I only see 2.6.26 patches, and I have 2.6.27 kernel version. Will 2.6.26 patch work or will I mess something up in the process?
My guess it then that this:
cd /usr/src/wireless-testing
sudo wget http://patches.aircrack-ng.org/b43-injection-2.6.26-wl.patch
sudo wget http://patches.aircrack-ng.org/mac80211_2.6.26-wl_frag.patch
sudo patch -p1 < b43-injection-2.6.26-wl.patch
sudo patch -p1 < mac80211_2.6.26-wl_frag.patch
sudo make net/mac80211/mac80211.ko drivers/net/wireless/b43/b43.ko
drivers/net/wireless/b43legacy/b43legacy.ko
sudo -s
make modules_install
is all that needs to be done to make packet injection work or is there anything else I need to do?
And lastly - no, I'm not trying to break into my neighbours or anyone elses network, don't really have any need for such actions. I just want to try it on my own AP to learn more..
thank you
Last edited by pootzko (2008-11-10 08:52:18)for successful injection, AP you're trying to crack has to have at least one client connected to it. and after that client makes some bandwidth, you 'steal and replicate' one of the packages it made, and with aireplay send it over and over... about 40 000 packages is enough
just follow this steps and it should work.
the thing I overlooked is when you start airmon-ng start wlan0 <channel> it made another interface mon0 which you then need to use, but i think that's not the problem in your case -
Kernel cnfiguration to get packet injection working with iwl4965
Hello,
I'm trying to configure my kernel to be able inject packets with intel wifi card using iwl4965 driver.
According to this: http://aircrack-ng.org/doku.php?id=iwlagn i need configre wifi options like this:
Networking -> Wireless :
[M] Improved wireless configuration API
[*] nl80211 new netlink interface support
[*] Wireless extensions
[M] Generic IEEE 802.11 Networking Stack (mac80211)
[M] Generic IEEE 802.11 Networking Stack (DEPRECATED)
[M] IEEE 802.11 WEP encryption (802.1x)
[M] IEEE 802.11i CCMP support
[M] IEEE 802.11i TKIP encryption
[M] Software MAC add-on to the IEEE 802.11 networking stack
So I fetched the kernel from abs and tried to configure it via make menuconfig. But i don't see these options. All i have there is this:
--- Wireless │ │
│ │ <M> Improved wireless configuration API │ │
│ │ [ ] cfg80211 regulatory debugging │ │
│ │ [ ] cfg80211 DebugFS entries │ │
│ │ [ ] Old wireless static regulatory definitions │ │

│ │ [*] enable powersave by default │ │
│ │ Rate control algorithm selection ---> │ │
│ │ -*- Enable LED triggers │ │
│ │ [ ] Export mac80211 internals in DebugFS │ │
│ │ [ ] Select mac80211 debugging features --->
Am I just dumb and missing something or what's the problem? .)
Thank you.

Run 'mplayer -vo help', see if those mentioned above are on the list. If not, you'll need to compile mplayer yourself. Though I have no idea what exactly the requisites are to get those working. If you can't get those to work, you're limited to fbdev which is indeed much slower than Xv, because colorspace conversion and scalign need to be done in software. So get vo mga working. -
WIFI Packet Loss/Jitter MacBook Air 11 & LION OSX 10.7.1
I started using computers more than 30 years ago when I was 5, I had my first IBM PC at the age of 10 and have never had any interest in paying over the odds for an Apple mac mainly because I saw the Mac as a kind of "Can't open nothing", one mouse buttoned retard of the computer world.
That is, until now.
I set up an online business 3 years ago and rented a dedicated server and set the whole business up in a cloud, so to speak. Having done that, all I needed a laptop for was a remote desktop connection and to run a SIP phone (Internet phone).
My PC based laptops had almost nothing installed on them, and I wasn't using software on the laptop itself, I was using remote desktop, so - why not try a MAC? The new Macbook Air 11 is small, light and made of metal and glass so should be robust enough to travel with me.
I have to say, this was the worst move I've ever made.
I opened the new shiny macbook and the first thing I noticed was that the internet seemed hit and miss. Moving around the room I managed to find a spot whereby pages woud load quickly. Strange, my £200 acer laptop was sh.t fast everywhere in the house. No matter, I packed it back away and carried on working on the Windows machine.
I've come to Newquay this week, and i've started to try and use the Macbook again in a hotel. The wireless signal in the room is low, and speedtest shows about 1 meg down and 3/4 meg up. That may sound bad to you, but remote desktop uses about 5k/sec (modem dial up speed) and the softphone, well, my Asterisk VOIP setup is confugured to use the GSM codec so that's 8k/sec each way + overheads.
This whole setup was deliberately designed to be "thin" so I can travel with ease and work on bad connections like USB internet sticks.
Anyhow, the Macbook was unable to hold a stable connection to the remote desktop or SIP phone, even though the speed test showed a whopping 1 meg up and down. What you may not be aware of is that there is more to a connection than the speed, there is the quality as well. How many packets are lost / how much "jitter" is on the line.
Anyhow, we're not living in the 3rd world, I ran a PINGTEST and it showed a small amount of jitter but told me the line was class B, online games may suffer but voip should be fine.
I unpacked the Acer, placed it in exactly the same spot as the Apple had sat in and it worked beautifully with 1 bar of wireless signal, all day long. Phone calls were clear.
So you know now what I'm thinking. I'm sitting here with my £200 acer because I can't use the £1500 macbook air 11. I paid nearly sixteen hundred pounds for this piece of .... and it doesn't ...... work. Time to contact Apple support.
2nd Mistake!
Representitive 1: - Told me that I can't compare the Macbook Air to the Acer, the Acer has Google Chrome and everybody knows Google Chrome is the fastest browser. I was told there was nothing more he could do, its probably a bad line at the hotel. When I explained the Acer works fine for voip I was told well, maybe it is getting a better signal. I explained the Acer has the cheapest possible parts inside it and paid 1500 for this macbook, expecting it to have quality parts inside and was told I'd paid for the size, because its so small but its not considered "powerful". Apple do you train your staff? Clearly not.
Thank god I wasn't paying to talk to this moron.
Representitive 2: - Had no idea what packet loss or Jitter was, got me to do a speedtest and said that looks fine. Then he got me to remove the WIFI adapter and re add it in the network settings.
Guess what, nothing changed, its still the same hardware and software.
Representitive 3: - Still not really understanding "quality" issues with the networking interface, I was asked to install the latest Java client. I did it, only because I wanted to comply with Apples wishes so they'd help me, but they weren't helping and Java has nothing to do with the network adapter, so that was useless advice too.
Apple seem to have no idea there is a problem, even though Google has pages and pages of people saying the same as me, and their own discussion forums have thousands of people complaining https://discussions.apple.com/thread/2664670?start=0&tstart=0
Finally, late yesterday whilst speaking to d.ck head number 3 at Apple support, we found a forum post talking about a fix, 10.7.1 update. I told d. head number 3 about the update and he suggested I applied it. So I did and everything looked great, for a whole evening.
This morning, I switched on again and the same thing, slow remote desktop, choppy unusable phone. Remember the phone needs less than 20k for a conversation, thats 0.2 meg. Speedtest again showing a whole meg both ways.
I called apple support again, this time being a little forceful, and I've asked for this to be escalated, but the bottom line is - they have no fix, they don't aknowledge this as a problem and I was told LION is new, so maybe it's got a bug..
I told the guy on the phone this is a network driver issue, the intermittency of the problem shows that and the Apple's lack of settings for the network adapter means the unit is autonegotiating with the router and choosing speed and duplex settings on its own. Sometimes it does that correctly, other times not and the connection although fast has a lot of noise / packet loss / corruption.
I've found a workaround, you put the unit to sleep and wake it up again and it runs fast until the next shutdown. Not really acceptable seeing as I was paying for "the cream of the crop".
I will definately not be recommending Apple products, and i'll certainly not be replacing the Windows laptops in my business with Apple's toytown system- i'd go out of business if I had to rely on this.
All there is left now, is to look at Boot camp and see if I can wipe this waste of space linux hack from the unit and install Windows 7.I started using computers more than 30 years ago when I was 5, I had my first IBM PC at the age of 10 and have never had any interest in paying over the odds for an Apple mac mainly because I saw the Mac as a kind of "Can't open nothing", one mouse buttoned retard of the computer world.

Hello,
I have a iPhone 5 that constantly switches back and for between 1.0Mb/s and 54.0Mb/s.
Is this any indication that the wifi is faulty on this phone? There are two other devices on the same ap
that are totally fine and maintain a constant rate.

Trouble with bpf packet injection
I am using OSX 10.4.9 power-pc Darwin Kernel Version 8.9.0
I am using libpcap 0.9.5, which uses the BPF api to capture and inject packets. Essentially, I need raw access to the Ethernet network. The problem I am encountering is that when I inject a packet using a bpf-write() command, subsequent bpf-read() commands see the injected packet. I tried avoiding this using the BIOCSSEESENT which disabled capture of all locally generated packets. But it only worked for the OS-stack generated packets, and not the packets I was generating via the bpf write() function.
Looking at the FreeBSD kernel, they solve the problem using a BIOCFEEDBACK setting, which disables the capture operating bpf-read()ing the packets you put in via bpf-write().
My questions are:
1. Is there some BIOCFEEDBACK equivalent on the MacOS that I am unaware of?
2. If not, is there some way I can edit the BPF source code on this version of the kernel, and run my own BPF?
3. If not, what is the proper way to request Apple to fix this shortcomming?
Thanks
-DavidI don't know much about this, but the Darwin kernel is very similar to FreeBSD. Indeed, in Activity Monitor, if you do a "Info" about processses, you can see the number of Unix and BSD system calls they make.
Try using the BIOCFEEDBACK setting on OS X. It may not work, but it's worth a try.

MBP C2D Wifi Packet Drop Solution
Hi,
I just figured out my Wifi problem. Hopefully this is useful to someone else.
The problem:
My Powerbook G4 has worked just fine with my D-Link DI-614+ router for the past year+, but when I got my MBP C2D the wifi connection seemed very slow and unreliable.
Opening terminal and doing a 'ping <router address>' revealed that about 30-40% of the packets were being dropped between the router and the MBP.
I set up my Powerbook G4 as a base station and connected to it and pinged in both directions with minimal packet loss 2-5% which in a noisy apartment building I consider fine.
So, what's the difference? Looking at the advanced tab -> performance settings I noticed that the 'Basic Rates' on the base station was set to 1-2-5.5-11 Mbps but the 'Tx Rates' was set to 1-2-5.5-11-22. As soon as I changed the 'Tx Rates' to 1-2-5.5-11 I stopped dropping packets. For good measure I turned off '4X Mode'.
So the 'enhanced' features of the DI-614+ were causing me problems. As soon as I turned them off and dropped to 802.11b rates it started working just fine.
Hope this helps.
Macbook Pro C2D Mac OS X (10.4.8)Many thanks, I too had the same problem with the D-614 and my new Macbook Pro - your suggestion fixed my problem.
Macbook Pro Core 2 Duo 2.33 Mac OS X (10.4.8) -
I know this package has been out of date for the longest time now and I adopted it the other day in hopes of just getting it to work with some simple updates. Well I have had no such luck with it being an easy fix. Right now I am just kinda messing with the package to see if I can get it work from subversion builds of madwifi but I have been kinda busy. I am just making this thread to see who all is interested in it aside from me and if anyone can help me out. I will have more info on the status after I class later today.
Injection is working here with provided madwifi from core, besides that it's also working with ath5k from 2.6.27. Both tested with AR5212.

Just copy it to an editor and save as PKGBUILD, and then replace the other PKGBUILD with this one. Good luck!

New WiFi + BT combined in one miniPCI
I would like to replace my existing built-in Intel(R) Wireless WiFi Link 4965AGN with a minipci card that can: o Connect to 802.11 a/b/g/n networks (like current card) o Compatible with Connectify o Have BlueTooth capabilities o Compatible with Windows 7 x64 o Optional: Does packet injection Any recommendations?
because it is not whitelisted in the bios, and if you install the code, you would get the error 1802 message.

IPod Touch 2G w/OS3.0: WiFi + BT observations and issues
I have an iPod Touch 2G with OS3.0. I have had the Touch for about 5 months and had a great experience using OS2.x. I upgraded to 0S3.0 the day it was released and have recently begun experimenting with Bluetooth connectivity. I've noticed a general overall slow-down in OS responsivness after installing OS3.0, but some of that has been reduced by freeing memory occasionally using iStat. Still, I often get brief (0.1s to 10s) but annoying periods of seeming lock-up with no touch-screen response when browsing play lists, surfing the internet etc. I should mention that I have about half (8G of 16G) of my storage (NAND) memory used. DRAM usage is more or less out of my control and often runs between 2M and 21M free depending on how recently I have "freed memory" using iStat.
When using BT with WiFi disabled I get predicable reasonable performance. No pauses or gaps in audio playback. Good sound quality. Great range for BT.
When using WiFi with BT disabled I also get reasonable performance. I get up/download speeds limited only by internet connection bandwidth which is 5-7 Mbps download and about 500-700 kbps upload at my home on my cable modem connection as recorded by Ookla Speed Test. I get 1.4Mbps both directions at work where we have a T1 connection to the Internet. My home download numbers decrease slightly (500 kbps)if I play a song (thru built-in speaker or ear buds) during the test. I attribute this to CPU utilization, but I can't be sure without more testing.
When I have BT and WiFi enabled at the same time, I begin to experience some problems....
1 - If there are no BT devices in range (BT is on, but not connected to anything) I don't notice any issues. However, if I stream audio to a BT device, I see a noticable slow-down in WiFi performance. I see home WiFi downlowad speeds drop to 500kbps (a 10x reduction) and upload speeds decrease to 300kbps (2x reduction). I have not tested this at work yet, but plan to do so. I'm not totally sure that this is a "problem" exactly as it could simply be BT and WiFi packets colliding with one another and / or sharing bandwidth on the wired interface between the radio IC and the CPU and / or a CPU bandwidth limitation.
2 - If I steam audio to a BT device while outside WiFi coverage (or between coverage zones) the audio will often times pause for anywhere from 0.1 to 1.0 second at a rate of about one pause per minute or more often. As soon as I connection to a WiFi network, the pauses go away. This is definitely a problem. It is very reproducable and one that I hope Apple will investigate and correct in a future OS revision.
For now I try to keep my BT and WiFi use mutually exclusive where possible. If I do use them at the same time, I make sure that I'm in a good WiFi coverage zone with reasonable internet connection.
If anyone else has experiece with WiF + BT useage on a 2G Touch with OS3.0, please report it so that (hopefully) Apple will have data to use for fixes in upcoming OS updates.
DougI just recently updated my iPod Touch 2G with OS3.0 and I also notice that the speed of my internet got slow when I use my iPod. I haven't tried the BT yet. Everytime I use my iPod using internet, mails or video streaming, I always test my internet speed using the speedtest app by Ookla when it was still at its 2.X firmware. Its the same speed as I check using my computer. Internet speed is 1Gbps.
But now, after upgrading it to OS3.0, the internet connection is slow. Download speed now is at its half. Upload speed is the same I think. I tried checking my devices such as the modem cabels and the WiFi config and the settings are still the same. I even tried to play with my WiFi setting and set it to Wireless G mode only, but the output is still the same.
I've check also the forums that's posted at the intenet and it says there that you could try these steps:
1. Try to power cycle the iPod - Same result. WiFi connection speed still the same.
2. Check if the WiFi has a WiFi address - Checked that under settings>general>about. It does have a WiFi Address and also the BT.
3. Try Reset Network Setting - I also tried that but nothing's change. Same speed as before.
I even tried to download another speed test app. But still the output is the same. I don't know what is causing the issue of the new firmware but the I the new features it. Hopefully there is someone there from Apple that could take a look at this.
As for now, I'll stick with the previous firmware.

Pandora + Bluetooth + Safari = serious wifi problems
Ok, so I've got the occasional "need to reconnect wifi" issues going on, like a good many people have alredy reported.
Last night I was streaming music to my belkin F8Z492 bluetooth receiver. Under 3.2.2 this worked great. Works good under 4.2.1 as well as long as I don't do anything else with the iPad.
As soon as I open safari and start hitting some of my favorites pages I my router starts loggging wifi packet errors by the hundreds. The playback on my stereo is crackly as all heck, and safari starts complaining that it can't connect to my router and asking for the password that it already has.
Seems like any 2 out of the 3 work ok, but all three together are just bad news.No guarantee, but there's a chance you may need to upgrade the iTunes software, which is revised every month or so. Good chance it's this.
The rare times that's happened to me, I unplugged the router (should you have one), restarted the router, and things returned to normal. This latter suggestion may not apply to you. -
E2000 Wifi Protected Setup Vulnerability
I am concerned about the Wifi Protected Setup vulnerability. The E2000 is running as a wireless bridge behind a hardwire router to allow wifi devices in my network. I have WPA2 Personal enabled with a strong password, as well as MAC Address Filtering, but I still have the concern of someone being able to spoof a MAC and crack the WPS. Is there a way to completely disable this router's WPS ability, so that the only way to connect to the router is to know the password? WPS has been found to be very easy to crack and it's nothing to capture wifi packets and determine the MAC address of authorized devices. What advice can you give me? Is there a version of the firmware that allows WPS to be disabled? I am unable to find firmware updates for this device. Or is there a different firmware that will work for this device and allow WPS to be disabled?
Thanks in advance for your advice and help with this issue.^^^ The WPS issue has nothing to do with Remote Management on of off. Not the same problem.

Mon0 error in airmon-ng on Dell Inspiron 6000 w/ Intel 2200BG wireless
I'm testing my home network's security, and no matter what I try,

Two things stand out:
It appears that you are using your internal wireless card,(Intel 2200BG chipset) which may not support packet injection. Some chipsets won't work at all, some can be patched.
Simple fix: grab a wireless card (usb) from ebay that is known to work. My favorite is the netgear WG111v2, about $10.00 U.S.

You don't want to be connected for this.
The best place to start for you would be http://www.aircrack-ng.org/documentation.html
You can check your chipset and find any patches you may need, as well as follow their tutorials.
You tube also has a lot of video tutorials.
Good luck.
Edit: this may be of interest, note the "mon0: ERROR while getting interface flags: No such device" errors.
