Hi, Like the title says. I've been having connectivity problems. I am using Windows 7 Home premium SP1 (x86). I can connect fine and after a (seemingly random) amount of time the connection will drop (at least according to windows).

I can also easily reconnect without a problem, but it will not pick back up the connection automatically, which is a problem because I use programs that need to access the internet and Often leave large files to download while I'm sleeping or not home. So If I'm not sitting at my computer to manually reconnect, then whatever i'm trying to accomplish doesn't get done. I'm using the. I had previously been running windows XP and this same thing would happen (though, much less often) but when it happened in XP it would automatically reconnect in a few seconds. I downloaded the drivers from ALFA's website incase the ones on disk were not up to date, and I tried both of them (they have a 'normal' and 'power control driver' option) and the problem remains. Also, I've never used an external wifi adapter before so I'm not sure if its supposed to work this way, but there are 2 'signal strength meters' in the system tray the standard windows one that you can click on and see available networks or go to windows 'network and sharing center' and then there is the ALFA one that you can click on and it takes you to the ALFA wireless LAN utility, where you can also get a list of available networks.

If anyone knows how to fix this, I would really really appreciate the help. Also below I'm going to post step by step of whats going on with pics so its pefectly clear. =============================== According to windows there is a problem with the connection, however according to the ALFA wireless LAN utility, the connection is fine (green bars means good connection, red bars means no connection) When clicking on the Windows 'signal strength indicator' in the system tray, it shows 1 of 2 different problems (notice the differences that I've highlighted with red boxes). No matter which one happens I can NOT access the internet.

Despite the 'problems' shown above, the ALFA wireless LAN utility shows that its still connected (while windows is showing a connection problem) To reconnect I switch to the 'profile' tab (which is just a list of neworks that i've previously connected to) and double click on the network. In this case it will be Enotria Public. The same one that (according to the ALFA wireless LAN utility) I'm already connected too After clicking on the network, the ALFA wireless LAN utility 'signal indicator' in the system tray will briefly turn red (signaling NO connection) while it 'reconnects'. Then it will turn back to green, and Windows network manager/signal indicator (whatever you call it) will proceed to reconnect as well. After this happens, all is good and I'm reconnected and can access the internet.

And here is Windows showing everything is all good. And here is ALFA wireless LAN utility showing everything is all good. One last thing that really throws me off. As you can see in pics above the ALFA wireless LAN utility is always connected, and it never drops the connection but even so, the internet will not work when Windows drops the connection.

However, When reconnecting I can access the internet BEFORE Windows reconnects. (I still have to reconnect as described above, but after I do so I can access the internet before windows FINISHES reconnecting) The tab shown in this picture was a web page that I loaded BEFORE Windows ever reconnected, and it is a page that I have NEVER viewed before, so its not just loading it from cache.

Quote: I had that suggested at another site I posted at as well. Anyway, have you also done these too? Have you updated your Wi-Fi adapter's driver to the latest by downloading it from the manufacturer's site? If none of the above suggestions worked please install and run from one of your wireless computers.

Double click the Xirrus Icon on your Desktop, Tap the Printscreen key on your keyboard, open up Paint then choose Edit from the Menu and select Paste, then SAVE it. Upload and attached the file here. Yes, I did those things:). Posted it over at sevenforums.

I'll copy it here too just in case anyone else wants to put their 2¢ in. ============ I've been a little busy and didn't have time to do it yesterday, but I really do appreciate your replies and any help you can give. I tried deleting profiles, didn't help.

I Did download latest drivers from website (although I think they are the same version I have on disk) As stated in OP, there were to different drivers for windows OS's 'normal/FCC' or 'power control/EC' I tried them both, didn't help. I got Xirrus. Warpspeed should be listed as a home network you can change this from public or are you referring to the free wifi?

By home network, are you referring to the windows setting that you choose Home (picture of house), work (picture of office building), public (picture of wooden bench)? In that case. Yes my router (warpspeed) is set to 'home' But I don't currently have internet service. I just use that router to stream media from my pc to my tv. For internet access I connect to 1 of 2 free internet services that are in range. Enotria Public (which is what i mainy use cuz its faster) or uptownfreewifi which are both set to 'public'.

I also have an update, some more info on the problem. The other day while searching youtube for this particular wifi adapter I saw a driver install video where the guy just did it through the device manager and that installed the driver without the ALFA wireless LAN utilitiy. So I uninstalled the ALFA wireless LAN utility and it also uninstalled the driver.

Then I used the method I just mentioned. Through device manager which installed the driver only and connected with the regular windows network manager. First of all it seemed harder to connect. But then it seemed like it was going to work. Got disconnected numerous times with 1 of 2 error messages (pics attached below) So I reinstalled the ALFA wireless LAN utility. More info, possibly a clue? Or maybe just a coincidence?

Let me start at the beginning. For a few months I had a BSOD (HDD was going bad), so I resorted to using a LIVE CD OS. Eventually I was able to transfer all my data from that HDD, reformat, run chkdsk, and reinstall XP. Ever since then My computer has not been able to keep time.

Then I got a new larger capacity HDD and that is when I installed windows 7 and the time keeping issues continued and this is also when the WIFI issues started. After checking google about the time keeping issues I'm thinking that my RTC (CMOS) battery is going bad. I'm wondering if this could also be causing the WIFI issues? On one hand, I had the same time keeping issues after reinstalling XP and the WIFI worked fine. On the other hand, once I installed windows 7 on the new HDD I still had the time keeping issues BUT.

(this is the clue or coincidence part).yesterday, out of the blue, my computer decided that it was going to keep proper time, which lasted for about 22 hours. During that 22 hours, I didn't loose my WIFI connnection a single time. Then the windows clock got screwed up again, and guess what happaned to my WIFI connection? Before that 22 hour span, the wifi connection would rarely stay connected for more than a couple of hours, just like the clock would rarely keep its time for more than a short ammount of time. Well I've had it since mid october. So I'm pretty sure its too late to send it back, which is a shame itself, because it turns out the network I'm using is N, I could have gotten the newer 2W ALFA that is N certified.

I had previously been running windows XP and this same thing would happen (though, much less often) but when it happened in XP it would. I downloaded the drivers from ALFA's website incase the ones on disk were not up to date, and I tried both of them (they have a 'normal' and 'power control driver'.

But I'd have a real hard time accepting that it is faulty hardware because it worked fine both with a linux LIVE CD and windows XP. Never dropped connection. Then when using 7 it started droping the connection.So I'm thinking its something to do with 7/compatibility with 7 or the driver? I suppose I could find out for sure. One day over the weekend I'll have to load XP and leave it turned on overnight and see if the connection drops at all.

In addition i would replace the cmos battery asap. If your model alfa does not have windows 7 drivers on their website you could try uninstalling the drivers via program and features and then on the setup file right click and choose properties and select compatability and choose vista or xp if your copy of the drivers is for one of those two operating systems click ok. Then install in normal way.

Edit: Can you please provide us with an ipconfig /all for us to review. I would like one when connected to Enotria Public. One from UptownFreeWi-Fi01.

Last one from!!!-WarpSpeed-!!! Please mark them so we know which is which. Also are they all set to connect automatically? Hi, the Enotria public one is set to connect automatically. The other are not because I don't use them often. The Uptownfreewifi also requires a password.

Not a network password like, WEP, WPA, etc. But when you sign in it redirects you to the login page where you have to create a free account with username/pass and it periodically logs you out and you have to renter the info. Here's the ipconfig /all.

They are named obviously to know which is which. Thanks again everyone who has responded. I installed XP (dual boot) booted into that and left it running all night, stayed connected fine. Back to windows 7 disconnected again.

Hi President i think i see a problem for you the Enotria Public has a default gateway 192.168.2.1 and Warpspeed also has a default gateway 192.168.2.1 so although Enotria Public is set to connect automatically it may be switching between the two hence loss of internet connectivity. What i suggest you do is log in to Warpspeed and change the default gateway to a different ip gateway address 192.168.0.1 so as not to clash with Enotria Public. If you have any static addresses on devices connected to Warpspeed then you would need to change those accordingly to within the same subnet of the new ip address of Warpspeed.

If they are automatically assigned you need not do anything they will be assigned a new address automatically when they reconnect to Warpspeed with its new ip address. I also suggest you add the 3 default gateways into your Wireless Network Connection properties in advanced under default gateways in change Adapter Settings in Network and sharing centre.

Update (6-27-07): I just found out that the makers of aircrack-ng just made this method easier. Two days after I wrote this article, they released a VMWare image of their entire suite of wireless penetration tools.

So, instead of downloading and using the generic BackTrack ISO (step 1 and 5) head over to. Update II (6-27-07): I guess packet injection under Windows is feasible after all!

The same time the VMWare aircrack-ng image was released, they also that lets you inject and read packets natively in Windows without the virtualization layer. What's more, you can use the Wireshark GUI instead of the aircrack-ng command line. Personally, I would still go with the Alfa (read more below) since it has nantenna connector. But that's just me! “.crack a WEP enabled access point within a couple of minutes. 3 minutes to be exact.” That piqued our curiosity in high school. My friend and I read about how the FBI publicly demonstrated a successful wireless network crack in a minuscule amount of time.

Inspired, we obtained a laptop and searched around our neighborhood for WEP encrypted wireless networks. Our plan was to show these local folks how easy it was to acquire their WEP key. Then, we would convince them that we were good, hirable technicians who could upgrade their WiFi WEP encryption scheme to WPA. We spent literally three days practicing, trying to crack our own network with Windows tools. But in the end, our plan never materialized.

We were too “n00b” for Linux. Crippled Windows Users and I’ll say it again, “I hate being a Windows user.” I hold great respect for computer hackers who are quick to grasp other operating systems, like Linux and OS X, without a problem.

But I, having been weaned on Windows since the day I touched a computer, have a hard time operating those unfamiliar user interfaces or lack thereof. I mean, more than half of Linux is in the shell command line! Aircrack-ng Win32 Binary Port Many users like myself have a hard time integrating with the computer hacker world. Most programs are written for *nix operating systems. Only when a kind, talented soul takes pity on us Windows amateurs and ports the code to Win32, are we able to use that software.

At the time, that Win32 software was almost non-existent for my friend and me. Even today, wireless network penetration software is still in the Linux stage. The main software suite,, is just barely supported in Windows.

When I tried the Windows port, it was slow, it did not accept my drivers, and it crashed numerous times. Basically, the Win32 aircrack-ng suite was pretty unusable and unstable. Virtualization Solution Finally, I decided to just try aircrack-ng in Linux.

I bought some equipment and ran the. After reading up on numerous Linux and aircrack-ng documentation, I was finally able to crack my home network!

While I was writing about (which is not no longer relevant) with VMWare, I had an epiphany. The same technique I used with VMware could also be applied to aircrack-ng! I tried it out and after a lot of trial and error, I cracked my home network once again. This time it was in Windows! Frequently Asked Questions So how did I do this?

Before you begin my tutorial, I suggest you read this FAQ for background information. • Why aircrack-ng? Sierra Games Evil Genius Online here.

Aircrack-ng is the most popular wireless cracking suite. Because of that, it is the most compatible with different types of hardware, it offers more forum support, and it is on the cutting edge of the latest WiFi hacking techniques.

• What are the main elements in cracking a wireless network? Airodump-ng: Gather “special” “faulty” data necessary to crack a network. Aireplay-ng: Stimulate the base AP station to generate the “special” data for aireplay-ng. Aircrack-ng: Take the data from airodump-ng and, with statistical or brute-force dictionary analysis, crack the key/PSK. • Why is Windows inherently unable to crack wireless networks?

Special (mostly unavailable) patched drivers are required to use these programs. • What about the Peek Driver?

First of all, the is special software written by the, sort of a wireless network version of. The bad thing about the Peek Driver is that it only allows you to read packets. Essentially, you can only use airodump-ng and aircrack-ng.

Theoretically, you can crack a wireless network with only these two programs but it is very difficult, drawn out, and plain inefficient. Without the speeding aid of aireplay-ng, cracking a wireless network may take days. Aireplay-ng helps inject packets and manipulate the wireless network. • Why does the Peek Driver not support aireplay-ng? This is because aireplay-ng requires the network card to be in a special state called “Monitor Mode.” In normal operation, the network interface is in “Managed Mode.” The Windows NDIS API (Network Driver Interface Specification) does not support any extensions for wireless monitor mode. Therefore, the only drivers that allow WiFi cards to be in monitor mode are in Linux. • I’ve heard of Windows tools that support packet injection.

But I also heard that they cost upwards of $300 and they are not nearly as fast as aireplay-ng. • So then there still is a way to use aireplay-ng in Windows with your hack? Basically, you run Backtrack as a virtual machine in VMWare Player. Since VMWare supports passthrough USB, the Backtrack virtual machine can directly access a compatible USB wireless network adapter. Note that my method will only work with a USB adapter since the only passthrough that virtual machine programs support is with the USB interface, not PCI, miniPCI, PCMCIA, PC Card, Express Card, etc. • So, I won’t need to know Linux commands and I will be presented with that familiar, friendly user interface that I am accustomed to in Windows? If you read the answer above, you know you will still be using Linux in Windows.

This is just a convenience of not having to switch between reboots. You will still be unable to avoid the obscure Linux shell commands! Hardware Let’s just cut to the chase. There is no reason to continue if you don’t even own the correct hardware. I’m sorry, but there is no workaround for this.

I’m a frugal person and I tried doing this the frugal way. It just doesn’t work. If you’re not willing to open your wallet, I would stop reading now. In my research and tests on compatible network adapters, there is only one with the least quirks and the least breakage for this operation. USB WiFi adapters with antenna connections are almost impossible to find. Usually you have to solder and mod the circuitry of another adapter to gain this functionality. Save yourself some trouble and just purchase this one.

Data Alliance Now, if you could only find where to buy this elusive piece of equipment. I found mine at, an / store managed by a man name. If you know of any other worthy store, please comment at the end of this post. Hardesty supplies most of my wireless networking needs. His inventory is the most cutting edge (and cheapest) that I have come across. Take a look at his store. It includes one of the most comprehensive resources I’ve read on wireless networking.

Nevertheless, don’t be tempted to purchase the high-powered. I’ve used it twice! It breaks easily and it is noisy. Additionally, “high powered” isn’t always a good thing. The chipset amplifies noise interference. Therefore, the TX/RX signal gets distorted. You could also be waving a flag to the FCC to smack down a fine, especially if you are using a high-gain antenna.

Worse case scenario, you’ll give yourself leukemia. We already have enough EMI as it is with computers and cell phones. Procedure • Download the latest version ISO image of the.

• Install the VMWare Player. You may want to read in my other blog, the freeware review.

• Download QEMU and create a *.vmdx hard drive of at least 4 GB. For the lazy, the command is. Device1 = ' • Install the BackTrack ISO on the slave virtual machine. • I suggest that you install VMWare Tools as well.

It makes VMWare integration with Windows a whole lot easier and faster. You’ll have to do some special extraction though. Read my previous for more details. • When you are actually viewing the desktop of the BackTrack KDE X-Windows, plug in your USB network adapter.

Windows will recognize and install it as a 'VMWare USB Device.' On the top of your VMWare window, you should see “Anonymous USB Device (Vendor: #### Product: ####)' highlighted. The '####' values will vary depending on the wireless USB interface hardware ID. If it isn't highlighted or Windows is trying to install the driver for Windows use (like 'Realtek Network Driver' not 'VMWare USB Device') just click the 'Anonymous USB Device' button and Windows will 'disconnect' the device from Explorer and 'reconnect' it in VMware. • After about a minute, open a console window verify that BackTrack recognized the hardware. Type, 'iwconfig.'

If you see an interface (like 'rausb0'), congratulations! You're in business!

In Closing On attack techniques, I won't get into the details. There are enough tutorials online. For starters, read the aircrack-ng documentation. They just added a new “” section. You'll learn a thing or two. Remember, pretty much any wireless attack you perform in Linux can also be done in this setup. Technically, you still need a form of Linux in order to perform this workaround.

However, it sure beats constantly rebooting to switch between operating systems. Windows users may find it comforting that they can always retreat to Explorer when things get scary. They don't have to fear that any real data can be lost or hardware destroyed. Leave any questions or comments below about your experience with this hack. I'll try my best to answer them.
