9300i invalid wep key

Hi all,
I usually can connect my wifi at the office.
Suddenly now I can not connect it again. It works fine at home.
I'm sure that I enter the right wep key. But it always said Illegal characters in WEP key data.
Please help me

Check to ensure that your WEP key format setting is correct, eg. Hex or ASCII. My guess is it could be Hex but you set it to ASCII.

  • "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?

    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).

    This also works (pretty much) with the J6480 printer.  I was using a Linksys wireless 'G' router which creates 4 WEP keys letting you choose which one to use.  I was sending key #2 and it would not accept it.  The only way i could get it to work was to disable wireless security-not my idea of a good option.  After numerious emails and 1 voice call to support with no ideas i decided to look here and finally got it to accept the WEP key.  I ended up uninstalling/reinstalling completely to get everything to work 100% but now it works like a charm.  For those of you with a similar problem, using a router that generates more than 1 WEP key, try using(sending) key #1
    note to HP: your email/voice support should be as good as your on-line forum support

  • My WEP key don´t work with Apple Base Station Snow

    Hello.
    I have an Airport Base Station Snow and two computers. One Apple iMac G5 and Apple PowerBook G4 667MHz. I have a new Nokia E65 and the phone can connect to internet using WLAN. I try to connect to my base station but I can´t enter because I enter my password (6 alphabetic password) and i receive an INVALID WEP KEY. How is this possible when I can connect with my two computers??...and others computers can enter too?....Anyone has this problem withan Nokia E65 and ABS Snow?

    Try using the network equivalent password. See KB 106864, AirPort Extreme: Getting an equivalent network password.

  • Can't set WEP key for broadcom-wl?

    I did a fresh install of Arch this morning at my office. I have an Acer Aspire laptop with a Broadcom wireless card that works with broadcom-wl (I've used the driver for a long time and it works perfectly... with open or WPA networks). The network at my office is WEP. So after installing the drive, adding lib80211 and wl to my MODPROBE (and !b43 !ssb), I reboot and see my wireless as eth0.
    If I try to iwconfig eth0 key XXXX-XXXX-XX or iwconfig eth0 essid WIFINAME key XXXX-XXXX-XX, no matter what combination I try, I get an error saying that it's an invalid argument for SET_ENCODE. I've check the Wiki and man pages for iwconfig, and can't seem to find any solution. Does anyone know why I can't put in a WEP key?
    ((Side note: everytime I've installed Arch, my wifi starts out as eth0 until I get connected and run pacman -Syu. Then I reboot and it shows up as wlan0, and my Atheros ethernet is eth0 or eth1.))

    Thanks for a response. So this is a fresh-from-the-oven install. I usually get my wifi connection set up and then create my user and go about setting everything else up. Meaning I've been trying as root.
    I can see the wireless network with iwlist scan and it shows up as encryption key: on. Also, I tried using each lib80211 mod or some combination thereof in my rc.conf. No dice.
    Lastly, since I didn't include it before, here's the exact error I get when I try to assign a WEP key with iwconfig:
    Error for wireless request "Set Encode" (8B2A) :
    SET failed on device eth0; Invalid argument.
    UPDATE: I can set the key using [x] between key and XXXXXXXXXX. However, any combination I'm trying of essid and key/enc isn't showing up in iwconfig. No errors, but my iwconfig information isn't changing. It's progress... I think.
    UPDATE #2: I can iwconfig eth0 essid linksys (the office next to us) and grab that one (I don't know their password ) and it updates iwconfig, but our own network doesn't update iwconfig when I run iwconfig essid. >.<

  • No able to connect to router with WEP key

    I want to connect to a router with a 10 digit hex WEP key. Entering this key into Airport, I says that the password is invalid. Using a XP system, I use the same key with a shared autentication option. How can I wireless connect to this router. I know the SSID name. I tried also to start with a $ sign, but no success.

    Put a $ sign in front of the password. So if your password is bnghtybngh type in $bnghtybngh.

  • Decrypt a wireless WEP key from across the country

    Hi All,
    I recently started a new job where there is no documentation whatsoever anywhere. I have about 200 access points spread across the planet, and the majority of them have WEP keys.  I have access to the APs and can see the encrypted versions of the WEP keys in the show run.
    I need to decrypt these keys for documentation/standardization purposes.  Are there any ways I can do it?  I tried making a key-chain in a spare router I have here and dropping in the encrypted WEP keys, but the router complained that the format was invalid, so I couldn't do that trick.
    R1(config)#key chain decrypt
    R1(config-keychain)#key 1
    R1(config-keychain-key)#key-string 7 <Encrypted WEP key placed here>
    R1(config-keychain-key)#do show key chain decrypt
    All the methods online assume you are within range of the SSID physically, which is not the case for me.
    Any help is much appreciated.
    Thanks.

    Hi George,
    No unfortunately I believe the keys are different everywhere.  You mentioned you've used tools in the past.  Do any of these tools work when the "cracker" is not physically near the wireless range/SSID?  I.E. I'm on the East Coast, WAP is in California.

  • WEP key issues

    I have been successfully using wireless over an unsecured network. Then I tried to connect to my home network with a WEP key, and, following this post I managed to get it to work with
    sudo iwconfig wlan0 essid MYESSID key [1] XXXXXXXXXX
    sudo dhclient wlan0
    After rebooting and suspending successfully several times, I suspended again and got
    Error for wireless request "Set Encode" (8B2A) :
    SET failed on device wlan0 ; Invalid argument
    whenever I tried the iwconfig command. (This was the error message I had been getting previously, before putting [1] in the iwconfig command.) Now, dhclient just hangs. I am really confused why this suddenly stopped working. I didn't do any updates between when it was working and when it wasn't. I don't know where to look for more specific error messages; dmesg and /var/log/syslog.log are unhelpful.
    Using [2], [3], or [4] instead of [1] prevents the error message from being output, but dhclient also hangs. In either case, iwlist wlan0 key lists all four keys as "off", even though I tried setting iwconfig wlan0 key on. Is this supposed to happen?
    My card is BCM4322 and I am using broadcom-wl from the AUR.
    Any insight would be appreciated!

    One of the problems with WEP is that the actual standard relies on a 10 character HEX key for 40bit WEP and a 26 character HEX key for 128bit WEP.
    In order to make things easier for people, vendors use certain algorithms to convert simple alphanumeric passwords (or passphrases) into HEX keys, thus enabling people to use simple memorable WEP password rather than lengthy HEX keys.
    The problem is that different vendors use different algorithms to generate the HEX key and therefore a ASCII password on an AEBS will be hashed differently on a Netgear client and vice versa.
    One thing is a 13 character 128 bit WEP password will be hashed by all vendors in the same way (if you use 40bit WEP then a 5 character password is required).
    Though sometimes not even that works and the HEX key must be used regardless.

  • 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.

  • Printer does accept the WEP key. any Solution, c309g wireless setup

    Hi, 
    i have a Photosmart c309 g printer. 
    I have been on phone with the tech for almost 8 hrs but with no solution. The end result being, they suggested to replace the printer.
    when i and also with assistance with the technician, ran the Wireless setup wizard,  my network is detected. when i hit ok on it, it prompts for WEP. Then i enter it, it displays connecting and then displays "ERROR " "Invalid WEP". 
    Below are the other few steps i tried......... >
    a> the printer was RESET , i guess it was SemiFull Reset . Then we tried running the wireless setup wizard, and it ended up with the same error  "ERROR " "Invalid WEP". 
    b> we installed through USB to have it in wireless .... the same issue.
    c> the tech asked me have the WEP key changed. I called my Router mfd and got the WEP key changed to only Numbers ( earlier it was alphanumeric ) , we then tried running the wireless setup wizard .. we got the same error message.
    d> We also tried Manually adding the IP, subnet mask and default gateway .... but the ping does not work. It says 100% loss.
    The tech concluded that it could be a problem with the printer wireless circuit . hence advised to replace the printer.
    I am returning the printer to the stores in a day or 2days. Let me know if "returning the printer " is the right thing to do or is there anyone over here who could suggest me steps to resolve it.
    Thanks !!!!!!!!

    Let's try an experiment.  Since I'm not sure of your exact configuration, I'd like  you to try some one of the following:
    If your Linksys wireless-router is also your ADSL modem -- disconnect the telephone line from the Linksys wireless-router and then power cycle the Linksys (unplug power, wait 30 seconds, plug power back in).  Leave the telephone line unplugged.
    -- or --
    If your ADSL modem is separate from your Linksys wireless-router, disconnect the LAN cable between the ADSL modem and the Linksys wireless-router and then power cycle the Linksys (unplug power, wait 30 seconds, plug power back in).  Leave the LAN cable disconnected.
    Power cycle the printer.  Wait 60 seconds for the wireless-router to power up completely and then run the C309g Wireless Setup Wizard from the printer's front panel (Setup -> Network -> Wireless Setup Wizard).
    If the printer connected successfully, then there is one more change we need to make and that is to set a static IP address for the printer.
    Open the printer's internal web page by browsing to its IP address.  Select Networking and then Wireless (802.11).  Under the IPv4 Configuration tab, select Manual IP:
    For Manual IP Address, use the existing printer IP address plus an offset.  For example, if the printer's IP address is currently 192.168.0.5, then use 192.168.0.30.
    For Manual Subnet Mask, use 255.255.255.0
    For Manual Default Gateway, leave blank.  This is important.
    Select Manual DNS Server:
    Leave both the Manual Preferred DNS Server and Manual Alternate DNS Server fields empty.  This is important.
    Press Apply.
    Turn off the wireless-router and reconnect the cable (telephone or LAN).  Now turn off  the printer and all computers connected to your network.  Wait 60 seconds then turn on the wireless-router and then turn on the printer.  Then turn on the computers.
    Finish up by installing the SW on the computers you want to print from.  One more suggestion -- do not install the HP Customer Participation Program.

  • Livebox password problems! WEP key?

    Hello!
    I am having major problems connecting to my wireless network using the Wanadoo Livebox. I'll give you the run-down in point form!
    - I share the connection with 2 other PC users who connect with no problems.
    - I have connected to the network before. Once i am connected, as long as I don't leave the house and connect to another wireless network (in a cafe etc) I can connect when I like. The problem is with that inital connection.
    - I have used my WEP key as my password in the past.
    - When I connect the usual way by clicking the airport icon in the corner and put in the WEP it says 'There was an error joining the wireless network'
    - When I try to connect using the 'assist me' section from System preferences (where I usually have most success) it tells me that 'the password is invalid' which I know not to be true!
    Please help!!!

    Yes, they can use your internet connection. As you say, no big deal UNLESS they start misusing it, deliberately or otherwise. For example, they get free use of your connection, use a PC on it, get hacked, and next thing there is a spambot spewing out spam by the megabyte on YOUR connection. Who get shut off?
    With your firewall in place on the mac your mac itself should be reasonably secure.
    Yes, they can sniff your traffic to the wireless hub. However, if you are sending credit card numbers presumably it is to a web page, and you wouldn't even consider doing that unless it was to a secure (https, little padlock shows closed onthe browser) page, in which case the details you send are encrypted.
    I would suggest two further steps you should take, if you haven't already. Firstly, tell the wireless hub not to broadcast its SSID. This will make it less visible to casual bad guys, but you will have to tell the mac what SSID to use (probably each time you connect). Secondly, tell the hub only to accept connections from specific ethernet addresses, and give it the address of your wireless card.
    If you are serious about the security you should consider changing from WEP to WPA, which is much harder to crack but also harder to configure.
    For more info try google - something like basic wireless security or security wep wpa should produce many hits!

  • 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, ?

  • How do i find WEP key for wrt54g

    Hi, my husband set up our system and i am trying to add a new wireless printer. He is out of the country for business, hence my problem. How do i find what the WEP key/ network key is? Thank you for your help.

    If you have other computer which had connected to this wireless network before, probably you can also use this wireless key finder on that computer to locate the WEP encryption key.
    Hope this helps.
