C4580 Wireless Networking Issue - WEP Security Key not accepted.

I keep getting this error whe doing network setup on my new Photosmart C4580.
"Your wireless rounter requires a WEP secuirty key. The security key configured on your printer does not match exactly. Reconfigure your wireless network WEP security key for your printer."
I have downloaded an updated installer. I have tried to access the printer via the IP address to make the change. It is never updated. When I run the Wireless Network Test Report it also shows it fails. I am entering in the first WEP security key (Index 1). I know the key is being entered correctly. I have even copied and pasted it. Nothing works.
Help Please!

Jim:
Thanks for your comments. I think you may be right. I have more information now. I installed a later version of the C4500 package (to fix another problem where the PC Firewall and internet access was disabled for 3 mins at startup), and the network setup/diagnostics are different in the newer package. After installing this the first time, everything worked - I mean everything, even scan from printer. During the Network Setup the wizard found only one network (mine). However, the Wireless Network Report said it had detected two.
However, the next time I switched the printer on, it never connected. Network diagnostics then told me that the PC and the printer were on different networks, 192.168.0.0 and 169.254.0.0 and that this usually results from two close networks with the default router manufactures SSID. This is not the case here - I am in any case in a very isolated country farm! It also (predictably) said the WEP was wrong. At one point in the diagnostic I can see it's trying 169.254.196.213. There's nothing on my network other than 192.168.0.* Attempts to reconfigure the network again show that there is only one network detected on-air, and no duplicate SSIDs, but the same result in the diagnostic - crossed-networks. Even re-installing the software won't fix it now. Whereas before I could at least print/scan from the PC and only the printer 'thought' the network was dead, now the network really IS dead and I am left with a USB-only setup.
I think you may be right that the printer somehow 'remembers' a phantom/ghost network. What I need is some way to hard-reset the printer. I saw in other postings that you know something about this, at least on other printers. Alternatively, I need a way to set the printer network parameters, including hard-coded IP address, over the USB but WITHOUT the router radio on, then switch it on and let the HP network setup wizard find it over the radio. Any ideas on that one please?

Lost Security key, not accepting my password

I'm trying to sync my Iphone with outlook.
I have 2 apple accounts for the cloud, I have misplaced my Security Key for the account I need to sync with. When I enter my ID and Password, I get an error message that says, account has been locked for security reasons. Can this be reset without the security key?
Thank you

See #6 here and reset the password, then follow the links to fix the Keychain also.

I have iphone 4 and it connect to some wireless networks and some others are not visible while other lphones can find these networks and i tried to restart the phone many times and there is no result, kindly advice

i have iphone 4 and it connect to some wireless networks and some others are not visible while other lphones can find these networks and i tried to restart the phone many times and there is no result, kindly advice

Some updates and clarifications:
1. I already have my 2.4 channel fixed.
2. Wireless network name is 8 alphanumeric characters; no spaces
3. Already using WPA2 security with a 10 alphanumeric key (again, no spaces)
4. I am running Airport Utility 6.0, Mac OS version 10.7.4
I should also say that these problems started happening less than a month ago...prior to that all devices where working normally.
An added update: My two e-readers (nook ST and Kindle 3) are also refusing to connect...perhaps confirming that I have 2.4 GHz issues?

Mimo access points with Static WEP security do not allow connection speeds above 54mbps

I am getting this message:
Access Connections - Mimo access points with Static WEP security do not allow connection speeds above 54mbps
If I switch from WEP to WAP i do not get the message but I still only get 54mbps speed. I have a Linksys Wireless-N Broadband Router. Is there a setting that I am missing???

Yes you need to use WPA-AES or WPA2-AES, or no encryption, to go faster than 54Mbps. This is part of the 802.11n spec.
That's not so bad, because if you have the right 802.11n card and use the right settings you can go up to 300Mbps!
What bites is that the 802.11n card which comes with X-Series ThinkPads is the Intel 4965AGN. It does not support the broader 802.11n 40MHz channel width option, limiting the top speed to 130Mbps .
The new ThinkPads based on the Montevina/Centrino 2 platform will most likely use the Intel WiFi Link 5100/5300 802.11n/WiMax cards, which I hope will fix this, coz I'm going to buy one!

I can see my wireless network,but my ipod4 will not let me connect to the network?

I can see my wireless network, but my ipod4 will not let me connect to it. When I try it tells me that it is unable to join. I can access the network on my laptop fine. I am also having trouble with connecting my ps3. It has the exact same problem. Can anyone help me?

The ps3 problem tends to indicate a router problem. Have you powered off and then back on your router?
For the iPod try:
- a reset:
Reset iPod touch: Press and hold the On/Off Sleep/Wake button and the Home
button at the same time for at least ten seconds, until the Apple logo appears.
- Reset Network settings: Settings?|>General>Reset>Reset Network Settings

Not able to connect to wireless network using WEP 128 bit hex password

I'm using a 128 bit hex WEP password on a Belkin wireless router.
My ascii passphrase is 13 characters.
I tried using the hex password generated by the Belkin router, as well as the hex equivalent of my ascii passphrase. Every time, I am told that either "there was an error connecting to the network" or the "password is incorrect" message.
I'm using channel 7, but have also tried with channel 11.
I tried using a $ sign in front of the WEP hex password. The $ does not work with Open Internet Connect or the Airport menubar.
I can connect if I don't use any encryption on the wireless network, and also through the Ethernet cable.
I have an iBook which connects fine to the wireless network.
So why doesn't the iMac work the same way ?

The security difference between NO encryption and any form of WEP is about 2 minutes or less for somebody looking to get in... besides having WEP enabled makes you look like an easy target since you think it'll stop anything!
Either leave it off, making Hackers think at least 3 minutes about WHY, or use/setup WPA of one form or another!

15" not keeping WEP security key...

When my powerbook boots into Leopard, it says my wireless network isn't available. I enter the WEP password and it works fine until the next reboot.
WEP keys aren't being saved.
After some research I found it might be the internal battery. Just replaced the internal battery and reset the PRAM/NVRAM and I'm still having the issue. Any ideas?

try zapping pram and power manager reset.

Network diagnostics asks for password for wireless network with no security

hi
I am trying to connect my Mac Pro to a wireless network which has no security settings. Other Macs in the house connect to the network with no problem, but the Mac Pro doesn't. I am setting up a new network as I have moved house. In the previous house the wireless worked fine on the Mac Pro.
When I click on the Airport Icon in the menu bar, the search wheel shows and it finds the network, but when I click on the name of the network typically it doesn't connect. Occasionally it does connect, and I briefly have internet access, but then the number of bars on the Airport Icon gradually reduce and then I can't connect again.
When I run Network Diagnostics from Safari, it finds the network also, but then typically asks for a WEP password for the Wireless Network when I haven't added any security to the network (occasionally it doesn't ask for a password and I can connect briefly)
I have tried resetting my Time Capsule and creating a new wireless network with a different name, but still experience the same issues.
I wonder if someone has any ideas as to what might be going on, and how I might be able to troubleshoot this.
Thanks
Nick

It is one of mine. Yes. It connects to it no problem, just doesn't connect to the actual internet. Network diagnostics has all green lights until the ISP and/or Internet point. If I walk through diagnostics, it will get to the point where it says that the network requires a WEP password. I don't know why it does that because my network is not password-protected (husband claims it doesn't work well with his VPN system to get into work network). If I leave it blank, the connection will work. Eventually, after the computer is put to sleep, I will have the same problem upon waking up. I just tried renaming the network and removing all preferred networks and rebooting. Let's see how that works.

IMac - WEP-key not accepted (wifi)

My iMac has been working fine during 1 month.
Then all of a sudden, when starting up, I got a message, that I was no longer connected to my wifi-network.
When I choose my (secured) network in the list, and type my WEP-key, it's not accepted (either a message "connection time out", or no message at all, the screen to type the password keeps coming back).
With my other devices (pc's, iPad, iPhone), there are NO connection problems.
With my iMac I still can use my neighbour's internet, and I can use my own internet, when I swith off the WEP-key of the router.
So the problem is that my key is not accepted by the iMac (and I'm sure that I type the correct password; I choose "show password").
As already mentionned, the first month I could go on the internet (the key was accepted).

WRT610N (no wireless connection when using security key)

My router hooked up hard wired fine. my wireless does not work when I set a security key of any type. It all seems to work fine with the system unlocked and no security set at all. I do have networkmagic 4.9 on my machines and have had for several years. My old wrt54G seem to work fine with a security key. It just got to where I had to reset the router a lot after a couple of years. How do I get this WRT610N ver:2 to work with a security key? I use Windows XP on all 3 computers,,,, 1 hard wired 2 wireless. I have had a WRT54G for a few years ,,,so I know how this stuff works,,,but I can't figure this one out. help please I want it to work right. Thanks,,,,I have a brand new WRT610N Ver:2

First of all, in the WRT610N, give your network a new unique SSID. Do not use "linksys". Do not use your old SSID. If you are using "linksys" you may be trying to connect to your neighbor's router. Also set "SSID Broadcast" to "enabled". This will help your computer find and lock on to your router's signal.
Next, in the computer, go to your wireless software, and go to "Preferred Networks" (sometimes called "Profiles" ). There are probably a few networks listed. Delete any network named "linksys". Delete any network with your old SSID. Also delete any network that you do not recognize, or that you no longer use. Enter your new network info (SSID, encryption (if any), and key (if any) ). Then select your current network and make it your default network, and set it to automatic login. You may need to go to "settings" to do this, or you may need to right click on your network and select "Properties" or "settings". Reboot computer. Your computer should connect automatically to the router (it can take up to two minutes). If you still have problems, temporarily turn off your compute software firewall, and try again to connect.
If the above does not fix your problem, download and install the latest driver for your wireless adapter.
Some users have reported improved wireless performance by switching to WPA encryption.
Note:
For WEP, enter WEP "key 1" (found in the router) into your computer, not the WEP password or passphrase.
For WPA or WPA2, enter the key (sometimes called password or passphrase) into your computer.
Win XP requires a patch to run WPA2 (= WPA with AES) . The patch is in SP3, so you will need SP3 to run WPA2.

Iphone/IOS 6 and Enterprise Wireless Networks Issue

Hi there,
Our company runs Cisco wireless using WPA2 Enterprise and AD Authentication. Now we currently have multiple vendor phones/laptops working fine including Apple Macbook Pro's, Apple Iphone 4s, Samsung Galaxy S2/S3 working on the wireless without issue.
However Ive been seeing issues with Iphone 5s and an Ipad now as well running IOS 6 where it just wont connect to the network. I am using Iphone configuration utility to install a Wireless profile with the certificate/AD credentials onto the Apple device.
I just loaded the profile on an Iphone 5 and it worked straight away.
However on ipad and other iphone 5's this is what happened, it associated to the Wireless but never got an IP address so never finishes connecting. just sits on spinning wheel.
Here is some output from the Iphone configuration utility console:

Passphrase or WEP security key

I am trying to add a new HP laptop to my wireless network using a linksys router 54G. The new computer is asking for a security key or passphrase. How do I locate them?

Login to your router, and go to the Wireless Security tab (or similar tab).
Find your encryption method (WEP, WPA, WPA2, etc.).
Nearby, you will find the key.
For WEP, enter WEP "key 1" into your computer.
For WPA or WPA2, enter the key (sometimes called password or passphrase) into your computer.

Wireless Network issue while using Apple Hardware Test remotely

I want to use Apple Hardware Test remotely through the disc on my MacBook Pro to check on a MacBook Air (old model). The problem is that when I start up the Air with the option key checked it does not recognise my wireless network and if I input it manually in the drop down list it will not connect. Other networks from neighbours are strangely enough visible. When I startup through the HD it instantly finds my Apple Airport network. What could be the issue?
Thanks

Hi,
Hmm.... I'm not sure I get what you mean or not but hardware test is a "in house" application for MBA and you don't need the installation disk to run the application. Unlike MBPro, you need the disk to run hardware test.

10.4.11 wireless networking issues for Intel iMac

After being prompted by software update to upgrade to 10.4.11 from 10.4.10, I did so, but found my computer stuck at the grey screen upon restart. I have since done the archive + reinstall of 10.4.4, which allowed me to onnect to my wireless network again (other Intel and PPC Macs are able to access the same network). I then downloaded and installed the 10.4.11 combo package as some have suggested on other posts throughout this forum; however the problem has returned.
Has anyone else had a similar problem and/or does anyone have a solution other than reinstalling 10.4.4 and upgrading to 10.4.10 again?
Cheers!

Mizraith,
I have the same setup as you (the WRT300N router & a macbook pro (sept 2007). I have been investigating these issues for a while now. First, to be quiet honest, this router is a crappy piece of hardware. Simply google the product name along with interesting keywords such as 'vanish' 'problem' 'issue', and make your own conclusion. Not to mention that the product has had at least 3 hardware revisions: it pretty much says it all.
Here are my takes on this, I have had 2 different problems:
1) First problem, the ESSID sometimes vanishs for a while. It is not macbook specific since I have observed that on my playstation 3 too. The only solution I have found to deal with this problem is to get to the wireless configuration of the router and change the radio band/wide channel, etc to something else. Then it'll work for some time before the problem reappears. I have contacted linksys tech support, and I strongly suspect that the support for N-mode is extremely incomplete, but of course they are not affirmative on this, otherwise they'd do a recall.
2) Second problem, the signals gets weak and the connection just freezes. Not sure it is macos specific, but the fact is that with macos 10.4.10, when it happened, simply setting aiport off -> on used to be OK. Since I upgraded to macos 10.4.11, the system will then appear to be connected to the AP with a good signal, but the NIC will be assigned a self-assigned ip address (169.x). This also happend after putting the system in sleep. It seams to happen more often on battery mode on my macbook. Manually rerunning the dhcp client does not help. Solution? You guess it, the r.e.b.o.o.t.
The router may be an unstable product, but there are some obvious regressions in the wifi support of macos 10.4.11, at least, in error handling. Here again, a simple google search for '10.4.11 wifi' with 'problem' 'issue' should convince you.
I have contacted the tech support of Apple regarding that issue. I didn't even expected to have a magical solution, but at least, some hints or even a mere acknowledgment. They never replied to my mail.
Let me know if you have some news on that issue, and good luck!

Hello,
I'm having problems with my wireless network connections, too. I did a fresh arch install with gnome3 some days ago to avoid any issues when upgrading, but i just can't access any wireless networks now. Everything else works like a charm, though. I followed the usual steps to set up my network/wifi with all the required modules and packages (broadcom-wl from the AUR, etc.) but it doesn't work like it did with gnome2 and xfce4.
My iwconfig/ifconfig output looks like dave1022's. Don't know if this is of any help...
The nm-applet in the gnome3 "panel" actually lists nearby wireless networks, but once I click on one of them, gnome asks me for authentification with my root password (user password does not work). I don't think it should be this way. If I enter my root password here, nothing happens whenever I click on the concerned network to connect to it. I deleted the /etc/NetworkManager/system-connections/<SSID> file to reset the authentification process.
I tried to consult the gnome3 pages in the wiki, but couldn't find any valueable hints either...does anyone have any idea what I might have done wrong or forgotten?
It's exactly the same for me and it's driving me nuts. I'm using iwl3945
[EDIT]
Well... actually installing the applet solved it for me. Is the applet actually needed for Gnome 3 or is a workaround?
