"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.

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).

"Invalid Index Key" Error - External HFS+ Drive

So I've got this external drive (Seagate Freeagent Go) that I formated with the Journaled filesystem. All of a sudden yesterday I could not access the drive after restarting my computer and when I could no longer see it on my desktop I opened Disk Utility. DU was able to see the drive and the partition but couldn't mount it, and when I ran a Verify/Repair I got the following:
Verify and Repair volume “Artimis”
Checking Journaled HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Invalid index key
Rebuilding Catalog B-tree.
The volume Artimis could not be repaired.
Error: Filesystem verify or repair failed.
Can anyone help me with a potential fix? I've had no power surges and had just been using the drive with no issues the night before

It's possible that Disk Warrior may be able to repair the drive's directory. If not you will have to reformat it.

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.

Why do I get a invalid WEP key when installing my printer?

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
thanks to DaniW-now I'm a happy camper

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.

Pre shared wep key

i have recently joined btfon community and have successfully connected to local hotspots using a nokia 5800 expressmusic mobile phone. while i have been away from home i tried to connect to avavailable hotspots but my phone tells me i require a pre-shared wep key .could anyone tell me what this is and how i obtain one?
many thanks acer

If it's asking for a key, then you're probably connecting to the wrong service - somebody's private internet connection. The WEP key is a password known to the wireless router, and which you also need to know to connect to the router. You get it if someone decides to give it to you.

Remove and check cartridge on right error message on 7410 all in one

I recently changed the black ink cartridge in my 7410 all in one printer. After changing cartridge it gave me an error message of " Remove and check cartridge on right". I have tried removing and reinstalling , cleaning connection points with clean damp cloth (water) and still cannot get error message to go away.
Any ideas would be greatly appreciated. Thank You.

NoProblemAtoll wrote:
I know this is an older thread but being it is a top Google result associated with the "Remove and check cartridge on right" error it justifies adding a helpful suggestion for other. Our findings have been HP Printers are very biased against refilled \ recycled cartridges. I own a total of (5)x HP 7310 and HP 7410 printers in my IT Consulting office. These are feature rich MFP’s with an abundant supply of ink available at generously economical prices. On the face of it, it sounds like a good reason to keep a bevy of last gen printers around. EXCEPT the printers work great with the $30-$50 brand new HP brand 96 cartridges from Office Depot or Staples. Unfortunately if you try and buy some recycled cartridges off ebay the Printers detect the recycled\refilled cartridges as a previously depleted HP cartridge that may not be genuine and the units suddenly turn on you. Miraculously the "Remove and check cartridge on right" only manifests itself with non-HP brand cartridges or cartridges that have been refilled. (We have even tried to re-fill out own refreshly depleted cartridges with like results.) Think of it as an HP service reminder conveying you forgot to pay HP their $30-$50 profit on your ink this go round. Remember you need HP Branded ink cartridges (HP = Homogeneously Proprietary). It’s like an intention flaw written into the firmware. Best guess (purely on conjecture) is there is a check in the firmware/drivers for if the cartridges has been previously installed, previously depleted, max install count, and expiration date validation. If it encounters a condition it doesn’t like you get this nondescript error.
[advertisement snipped]
The above post is filled with conjecture and speculation, but is not based on fact. The Officejet7410 is not programmed to reject refilled/reman cartridges. It will check cartridges electrically for various things and will reject cartridges that fail. Typical failures would include a cracked printhead (caused by rough treatment - dropping the cartridge even a few inches for example), or open electrical connections caused by debris on the cartridge contacts. Cleaning the cartridge contacts as shown in the document here may resolve the issue in case of poor electrical contacts.
A cartridge that has been previously used in a different printer will likely be marked as empty, but the printer will happily print with a cartridge detected as empty.
The reality is that the quality of refill and reman cartridges are very variable, but generally poor. The study here has a study conducted by a testing facility, here is another study.
My personal experience has been similar. I donated an HP all-in-one to my son's high school years ago. Sometime later I got a call from the teacher complaining that it was not printing properly. I went and took a look and found they had put in a renam color cartridge that was not printing one of the colors*. They tried another cartridge, which also had a problem and then finally the third cartridge worked. I asked why they used renam cartridges and he said they bought these because they were cheaper. I asked if they were 1/3 the cost....
*The color missing had nothing to do with the printer - blotting the bad cartridge on a damp tissue gave only two of the three colors that would normally be present.

HP 4500 All-in-one Wireless Wep error

I have installed the HP 4500 All-in-one wireless printer. It recognizes the Apple network and then ask's for the WEP. I enter that code and it says invalid WEP. It is not the incorrect password........Help!
This question was solved.
View Solution.

Yup Open Airport Utility (let me know if you cannot find it - I don't know what operating system you are using), click once on your Airport Extreme on the left of the window, then click "Manual Setup" along the bottom.
Navigate to the Wireless tab and then change from WEP to "WPA/WPA2 Personal". Enter a password that YOU create. Make sure it is at least 13 characters, numbers and letters, upper and lower case.
Click Update.
Now go to each of your wireless devices and re-login to your wireless network with your new password.

WEP Key decrypt error + Symbol 9060

I have a WLC 4400 running ver 3.2.150.6. The LAP is a 1242AG-A-K9. I am getting this error message on the wireless controller log when I try and use my Symbol 9060 RF units the message is:
WEP Key decrypt error. Station MAC Address is 00:a0:f8:ba:b5:36, Base Radio MAC is 00:19:a9:0f:d7:90 and Slot ID is 0.
My setup is WPA using 802.1x and the units do authenicate but then after a random period the users lose their sessions. Actually doesnt seem to matter whether I am using WPA or WEP, i still drop. I havent had this problem with the fat APs. Any ideas?

Cisco is saying the WEP error is a known bug and its a fake message, so that is probably not what is causing the drops. When the clients first started dropping I also noticed another error message but it hasnt show back up till today when i put more client guns back in use. the error is:
WPA MIC Error counter measure activated on Radio with MAC 00:19:a9:0f:bd:80 and Slot ID 0. Station MAC Address is 00:a0:f8:d2:34:98 and WLAN ID is 1.
Any thoughts?

WEP Key decrypt error

We have WPA2 clients and WLC4402, why is the controller reporting this error message. Does anyone know ? It doesn't seem to effect the connection but I'm just concerning.

Hi
We are using 802.1x and 104 bit WEP to authenticate against a ACS Server
(LEAP)
Sporadically we are also getting the same errormessage muliple times:
Wed Nov 1 12:09:01 2006--WEP Key decrypt error. Station MAC Address is 00:40:96:b1:d1:01, Base Radio MAC is 00:0b:85:71:21:01 and Slot ID is 1.

It seesms that this error-essage are dieplayed in different configuration cenarios.
Does anyone know what exactly the reason is for this error message is.

Unable to boot: Mac HD verify error - invalid index key

Thank you in advance for your assistance. Please provide a detailed response. There is a lot I have to learn about computers.
I allowed my macbook air mid-2013 os x 10.10.2 to update yesterday. I didn't look at what the update was (just saw the notification and clicked restart). It shut down, but did not restart. When I try to boot, the loading bar slows and tops at approx 35%, and the computer shuts off. I can boot in recovery mode. In disk utility, on the left side the first line is Macintosh HD. I can verify this without errors. The second line is also Macintosh HD written in lighter grey. I cannot interact with this until I click unlock and type in my password. After doing so, it is written in dark black, and I then have the option to verify disk. Doing so, I am given the follow error in the log:
(in red) Invalid index key.
(in red) Invalid record count.
(in red) The volume Macintosh HD could not be verified completely.
(in black) File system check exit code is 8.
(in red) Error: This disk needs to be repaired. Click Repair Disk.
A pop-up message says:
Disk Utility stopped verifying "Macintosh HD"
This disk needs to be repaired.
I click an "ok" box, but the Repair Disk button is not available.
At this point, I noticed the "mount" button is available. If I click this, it says:
Mount Failed
The disk "Macintosh HD" could not be mounted.
Try running First Aid on the disk and then retry mounting.
Of course, the only option in First Aid is Verify Disk, which I have already done.
I also tried reinstalling OS X from safe mode, but the installation failed. I would ideally like to fix this without losing any data, but my computer is backed up so it won't be terrible if I have to start fresh. My SSD failed on my macbook air 2012, so I hope this isn't happening again.
Thank you.

WAP Error Message Received invalid EAPOL-Key MIC (msg 2/4)

Hi there
can anyone help me with this error message Received invalid EAPOL-Key MIC (msg 2/4) .
Time Stamp

Service
Description
Nov 5 2012 15:11:27
warn
hostapd[4365]
Received invalid EAPOL-Key MIC (msg 2/4)
I only get this message from one device when connecting to the WLAN.
This happens only from time to time. Sometimes it connects without any problem.
Appriciate any help.
Sincerely
Patrik

This is an error when the STA (the computer) constructs the packet. 2/4 is indicate of the handshake process where it sends a nonce-value with its own MIC. A MIC is a message integrity check (or code).
Basically, this error is saying, whatever that computer is sending is invalid. You can try to make the AP behave differently such as force the use of AES instead of AES+TKIP depending on what product you have. Pretty much removing "mixed" wireless networking. As example, try using WPA2 (AES) only.
Such errors are more common using TKIP since it is the nature of TKIP to send a per-packet-key.
