Question on WEP key configuration

Hi Guys,
I am following a configuration example to test WEP with open authentication configured on an Autonomous mode AP. I have noticed that when I configured a 40 bit key with value "abcdef0123", the client could not connect to the network (not getting a valid IP address), however if I change the key to "ABCDEF0123", then both of the clients are connected without any problem. I have tested this wtih windows XP and 7, both gave me the same result.
Initially I did not think this could be a problem after checking the keys configured on the client and AP, however when I go to the network and sharing center in windows 7, I noticed that after configuring the SSID and open it again, all the letters contained in the key became upper case, I have configured both supplicants with key "abcdef0123" to start with, however it became "ABCDEF0123" for some reason.
looking through the configuration guide I could not find anything related on this topic, did anyone noticed this problem before and is this an expected behavior?
Thanks in advance for your time and help.

First question ... Why on earth would you be configuring WEP with windows xp/7 clients ? go for WPA or go for open, but WEP makes very little sense.
Second, normally WEP is based on hexadecimal value, so lower or upper case is irrelevant since a letter a->f just represents a number. So the AP representing them as upper case makes no difference, it's anyway a number behind it. The problem must reside on the client who doesn't know if you are typing an ascii or a hexadecimal key ...

How to view my WEP Key ?

I need to connect to my Airport Extreme Wireless Network from a WIndow XP configured Macbook.
WIndows requires the Hexadecimal WEP key to connect.
How do i get this?
To be sure, i have read many similar questions on this forum and tried :
- The network preference panel. The "show password" tick option remains grayed out.
- The Airport utility. The "equivalent network password" on the Base Station meny remains grayed out.
- The Keychain access utility. I can only find the alphabetic passord, not the hexadecimal WEP key (of course tried to enter the alphabetic one, but did not work, so i assume it is expecting the hexadecimal one....).
- In one of the posts, the contributor is bemoaning about an upgrade on snow leopard that makes getting to view the WEP key absurdly complicated. He provides a link :
http://www.adamriggins.com/2009/11/16/how-to-view-saved-wifi-passwords-in-osx-sn ow-leopard/
... which unfortunately is not working anymore...
I do clearly remember easily retrieving the WEP key 2 or 3 years ago, maybe from OS leopard at the time. I don't quite understand why it's been made so difficult now. Was there a security issue ? then is there an Apple note summarizing those facts and recommanding steps for previously set networks ?
Anyone who can help on this is very welcome.
Thanks in advance

well first of all why are you using wep? don't you realize that all wep networks can be cracked in 15 minutes?
older versions of windows xp do not know WPA/WPA2 if you are running the latest service pack then it should support WPA or WPA2
if for the life of you cannot determine the WEP password no matter how hard you try. i found mine by going into keychain and clicked on show password and there was my wifi password
then you might as well just download the latest version of airport utility, write down all the important settings, and then use the reset button to erase everything and then reconfigure it from scratch. and then you will know your password.
while you are there, if you can turn on wpa, by all means turn it on

Passphrase left blank but not taken to page where I can add WEP key per instructions?

Hi... can anyone help me with this relatively simple question?
Model: WVC54GCA
Step "N" tells me to leave the "passphrase" field blank if I want to manually add the WEP key on the following screen. It says to hit next which will bring me to this page. However, I am not brought to a page where I can add the WEP key instead just to a page with a summary of settings. I've tried resetting over 10 times and going through the directions again to see if I missed something, but it seems as if this software just has a bug that takes the user to the wrong page? Does anyone know what I'm doing wrong? I'm just trying to get to a page where I can manually add the WEP key. THank you very much.

To setup your Camera rather than using the CD setup you should use it's web interface...
1. Connect your Camera to a computer, click on the Start button >>> Settings >>> Control Panel >>> Network Connections - Right click on the icon for Local area connection and go to properties- On the 'General' tab select 'Internet Protocol TCP/IP' and click on the Properties button- Select 'Use the following IP address'- Provide IP Address - 192.168.1.5, Subnet Mask - 255.255.255.0...Click on Ok button to Save and Click on "Close" on main Properties window...
2. Now open an Internet Explorer browser page on your wired computer(desktop).In the address bar type - 192.168.1.115.
Use admin for both Username & Password in lower case...It should open your Camera set-up...
3. Once you get to the set-up page you can follow this link to change the Camera Settings...While changing the Camera settings you have to make sure that the Wireless Settings(SSID/Network Name and WEP Key) are identical on both the devices(router and camera)...Also make sure to change the camera's default IP to match your network and Gateway Address should be your router's address...ex. Camera's IP Address : 192.168.1.115(assuming your router's default address is 192.168.1.1), Subnet Mask : 255.255.255.0, Default Gateway : 192.168.1.1.
4. After configuring the Camera you should disconnect it from the Computer and go into Local Area Connection TCP/IP Properties and set it back to Obtain IP Address Automatically...Disconnect the Camera from the computer and power cycle both the devices(Camera and Router)...Your camera should be configured...
In case if you don't get the Camera set-up just leave it connected to your computer and reset it for 30 seconds...
Press and hold the reset button for 30 seconds...Release the reset button...Unplug the power cable from your Camera, wait for 30 seconds and re-connect the power cable...Follow Step 2, Step 3 & Step 4...

How to set up wireless WEP keys in GPO? - possible?

Summary:
How to switch users from using Intel ProSet to manage their legacy SSID w/ WEP to using Windows Zero Config w/ both legacy & new SSID's automatically?
Detail:
Some of our sites are still using WEP for wireless encryption (believe it or not) over 802.11b AP's.
We're in process of upgrading encryption from WEP to WPA2 & from 802.11b to 802.11a/g AP's.
One immediate challenge we have is how to keep both networks in parallel and make this transparent to the end users.
We can't cut all floors over at once, but need to do one floor at a time because users move from floor to floor.
We were able to roll out the new network / SSID in Windows Zero Config through GPO, but learned that we can't do the same for the legacy SSID - setting WEP keys isn't an option in GPO, at least according to the server admins.
Does any of you know how we can do this in an automatic & transparent fashion?
So far we've been using sneaker net to switch users from Intel to Windows, & configure WEP keys in Windows, which is taking up way too much time.

If you use a GPO to manage the wireless it will disable the intel proset software. This can have a negative impact, as you may have user that like to use the Proset when not in the office.
If you are going to use GPOs then the transition should be pretty smooth, just setup the new secure SSID first and then roll out the GPO. There are several M$ patches that you should install as well. Do a search for Microsoft Wireless hotfix and rollup and you will find them.

My new smart TV recognizes my network, & asks, "Please enter you WEP keys (10 or 26 hex digits)" but my netwotk uses a password of 6 characters. How can I get my smart TV to connect to my network?

I have a current iMac with the latest OS update.
My new smart TV recognizes my network, & asks, “Please enter your WEP keys (10 or 26 hex digits). My Airport Express, an early model, only requires a password of less than 10 characters.
When I open “airport utility,”on my iMac it tells me this version doesn’t support my base station & says go to “Airport Service & Support.” That’s what got me here.
My earlier MacBook runs OS 10.6.8. Its version of Airport Utility works. Its Airport ID has 17 characters, & uses the same password to access the internet, but it also has a “wireless password” of 26 characters, but only shows me the dots. i haven’t the foggiest notion what the characters are, if I put them in there years ago when i did the original configuration, or if they got there otherwise..
I’m afraid of changing those settings for fear that I’l mess up the whole thing.
How can I get my smart TV to connect to my network, ?

Very simple question, how do you configure windows 8.1 to use a SF card as the default install location for software applications?

Very simple question, how do you configure windows 8.1 to use a SD card / external drive as the default install location for software applications? Primarily interested in apps installed from the windows store. This should be available in the settings
charm within the windows store. This must have been overlooked in the development of windows 8.1 or is a bug.

The registry method does not work with 8.1. I found this out the hard way. Doing it on 8.1 will leave you reinstalling the OS if you didn't do a SRP beforehand.

What is a WEP key and where do I find it?

Any dumbed down help would be greatly appreciated because I'm close to returning the base station time capsule thing. I can connect macs because I know the password, but friends with PCs can't connect, I can't connect a netbook or a blackberry because they all request this wep key. I can't find it and I don't know what it is. Sorry for being stupid, but I'm a loss. Thank you.

-Connect the ethernet form the windows PC to the Time Capsule.
-Update the Windows Computer to SP3 and then head to the Microsoft Update Support Site and then search WPA Patch or WPA 2 Patch
-Download and Install the patch
-discount the ethernet from the Time Capsule and try to rejoin the wireless network
-If still having issues then change the Time Capsule security settings
Or change the security on the Time Capsule From WPA to WEP (Uses WPA By Default)
Step to do this. On Mac
-Open finder and head to the Application folder
-Once in Applications Folder Please find the Utility Folder and open it.
-Now that we are in the Utility Folder please find a application called *Airport Utility* (Not airport admin utility)
-Please Open Airport Utility
-You should now see the time capsule on the left hand side of Airport Utility (AU)
-In The bottom left hand you will see a button that says *Manual Setup* please click on it.
-Once done reading the configuration file you should see the *Summary Page*
-Now there are some tab's please click on the *Wireless Tab*
-Now you should see lots of info don't worry we only need to change one thing and that the wireless security
-Right now it should say *WPA / WPA 2 Personal*
-PLEASE HOLD OPTION and use the MOUSE TO CLICK ON THE DROP DOWN FEILD
-Now you should see a a few security protocol Please select the *WEP (Transitional Security Network)*
-Enter a New Password this password may need to be 8 or 13 numbers / letters
-Now Click UPDATE
-Now you are using WEP
-NOTE: You may have to reselect your network using airport

Windows won't remember my new WEP key?

Every time I go to log on to my ssid it has my old network key. SO I enter in my new network key and it doesn't not take it.
My connections show are shown to be working and at a high rate but I can't get by browser running?
BTW I using a Linksys WRT54GS router from my desktop to my laptop via a cable connection. I had the system running fine but I changed the WEP Key recently and now it's no longer running.Message Edited by jakethesnake on 11-17-200611:58 PM

Sorry, but it is not fully clear what you are doing and what is happening exactly.
Do you have Windows XP?
Do you use Windows Zero Configuration or a laptop specific software for the wireless connection?
How do you know it still has the old network key?
How do you know that it does "not take" the new key?
What do you mean exactly when your connections are shown to be working?
If the network key is incorrect the wireless card should not be able to connect. Thus you don't have a working connection. Instead the wireless connection icon in the tray should show a red cross to indicate that it is not connected.
Also, when changing the network settings, I usually find it easier to change the settings on the properties panel of the network connection (if you are using windows zero configuration). For wireless connection there is a wireless tab. In the lower half you'll find all SSIDs you have configured. Click your SSID and edit the settings as you need.

WRE54G v3 - WEP key setting when using ASCII passphrase

When entering WEP information for this device you may notice that the range expander is asking for the WEP key in hex (for example: 128 bits 26 hex digits). If the key that you have set in your router is using a passphrase then you will need to convert it to hex. Entering the passphrase and clicking the generate button will not work if your router is set to use ASCII as the WEP key format. The result seems to be that the PC may attempt to connect (and/or show as connected) but will not receive an IP address and does not really connect to your network. Strangely, the WRE54G will show that it has connected sucessfully to the router. Instead, convert the passphrase to hex one character at a time then enter the hex digits as the hex key. For example: if you are using 128 bit and your passkey is: 1234567890123 then enter 31323334353637383930313233 as the 128bit hex key (1 in ASCII = 31 in hex, 2 in ASCII = 32 in hex, etc...). http://www.asciitable.com/

Hi, The solution I posted above works for me . I can ping the WRE from the network and access the configuration page. The wireless router I am connecting to is a TP-LINK TL-WR340G. The extender is a WRE54G ver. 3 running v3.04.01 firmware. Instead of converting the passphrase to hex I could just set the TP-LINK router to use a hex key instead but thats a pain. Then I would have to type in a long hex key when adding another wireless device to the network or when allowing a guest device on the network. An ASCII passphrase is so much easier to remember and much less typing. If I leave the TP-LINK router set to accept an ASCII passphrase then convert the ASCII passphrase to hex and enter it into the WRE extender then I can use an ASCII passphrase when connecting a device through the extender .
What I found confusing initially though (before finding the solution) was that if I enter the ASCII passphrase into the extender setup and click the generate button for it to generate the 4 hex keys, the extender claims to connect successfully. I cannot ping it from the network and a wireless device will not get a connection through it but the light does turn blue and the setup screen shows the correct mac address in the link status section. Seems like a bug...

Help? Can I change my WEP key on my router?

Hi All...
I'm a newbie to these forums and I have a question... Can I change my WEP key on my FiOS wireless router? (Actiontec MI424-WR Rev. D)
My neighbor, who also watches our dog when we go on holiday, has been using my internet from his house. He freely admitted this. My FiOS is much faster than his throttled Comcast and since he's a power user (torrents) he frequently uses my internet connection for all his massive downloads. His usage knocks me off PS3 and noticeably slows my internet speeds down.
I know he has my IP and WEP since he spends weeks at a time in my house. I'd like to change my WEP key and keep it hidden from him.
How can I kick him off and prevent him from hopping back on?
Thanks in advance.
Emma

Well... theft of services issues aside since what your neighbor is doing is illegal ...
I agree with Justin. Go with a WPA2 connection and use a reasonably long and complex password. I'd change the SSID as well although that's not absolutely required. Also make sure you change the userid/password on the router as well in case they know it. Don't get wrapped up in hiding the SSID or turning on Mac authentication -- while they don't necessarily hurt, they don't add anything appreciable to the equation and just make your own life more difficult.
Now ... I'm going ask, are you even using the the wireless at all? Perhaps you are using a hardwired PC to the router and really don't need the wireless? If so, just go into the router and turn the wireless off. Your neighbor can't steal what isn't there.
Oh ... and it might be time to get the key back and find a new dog sitter.

Still Having Problem With WEP Key

Hi:
I have been reading this forum and looking for WEP related topic however I still haven't solved my problem. So here is my problem and see if anyone from this forum can help.
I set my linksys to make WEP key mandatory. I used 128 bit key and was able to generate 104 bit key (26 hex digits). It works fine on my wife laptop (COMPAQ), it can communicate using this key. However it never works on my IBM/Lenovo T43P. The only difference is I am running Funk/Juniper Odyssey Client Manager software. Yes I have entered the 26 hex key properly and still doesn't work. It does work however if I disable the WEP key. Any idea what the problem is?
I took my laptop to my brothers house who is using DLINK router and use a different WEP and it works fine. So it seems like this WEP key doesn't work with my Linksys router. By the way my Linksys router is BEFW11S4.
Thanks,
Jim

If your one laptop is already working iwth same 28bits WEP key ..... i dont think so that there is any issue with router ......
You can configure the Odyssey Client Manager as per the settings in the router ....
Still if you want you can use WEP 64 bits key on the router ...check on both the laptops if they are able to access interent .....

Wep key not working in rc.conf

Whenever I restart my computer, I can't connect to my network (and hence the internet) because, I believe, the wep key isn't set, even though it's in rc.conf. I have to manually type
iwconfig ath0 essid *SSID* key *CORRECT KEY*
everytime. I know that the key is correct in both because I copied the key for iwconfig right out of my rc.conf. I don't know what's wrong.
rc.conf
ath0="ath0 192.168.1.42 netmask 255.255.255.0 broadcast 192.168.1.42 essid '*SSID*' key *CORRECT KEY*"
INTERFACES=(ath0)

I don't think you can set the essid and WEP there. See the wiki for wireless network configuration.

"Invalid WEP Key" Error on 7410 All-in-On Wireless Set Up

My 7410 has been connected wirelessly for over a year but I just installed a new router (Linksys N600) and can't get the wireless connection back up. All other wireless devices are connecting to the new router. Using WPA2-PSK[AES] security on router. Using installation wizard on front panel of printer and it is locating network SSID fine. But only allowing for WEP key and giving me error code every time it is entered. Have tried to change length of key on router to 5 or 13 characters and also tried 10 HEX digits. Have powered off/on the printer and restored to factory network settings. No luck with anything. The Cisco router I previously had installed was also an N router - no problems connecting the 7410 wirelessly but swapped it out because of too many lost connections. Any advice?
This question was solved.
View Solution.

If your WEP key is all alphabet then it is not WEP, it is WPA or WPA2. As discussed above, this printer will not accept WPA2.
Get into your router settings and change your wireless security type to WPA or WPA/WPA2 (you can keep the same passphrase).

How do I find my WEP key on my macbook pro?

I am trying to hook up my blu ray player and it says that I need a WEP key and every time I put in my wifi router password it will not take it. It says The number of characters is invalid. Please check your entry and try again. My question is can I find the WEP key through my laptop and if so how do I find it. Any info would be greatly appreciated.

You don't have a WEP key. Your security is set up using WPA or it is not set up for security at all.
