Name of my iMac suddenly changed on home network

I received a prompt saying the name of my iMac was being changed on the because there is another computer with the same name on my network. I have no idea why this happened. As far as I can tell, my iMac is the only one with that original name. Can anyone tell me why this happened. I have virus barrier 6 installed, and there is no indication of outside mischief.

There are several potential causes for this, among them is having mounted an additional volume containing OS X.

Intego Virus Barrier is self-infliced mischief. Get rid of it. It will do nothing but cause problems for you.
Be sure to follow Intego's uninstallation instructions with care, and verify its complete eradication.
Do not install such junk on a Mac.

I changed my home network.

I changed my home network. The router and all information has changed. My time capsule stop updating. I can see the time capsule in the airport utility, but am unable to access it. How do I add my current capsule to my new network?

Reset it to factory and start over clean new setup;.
Factory reset universal
Power off the TC.. ie pull the power cord or power off at the wall.. wait 10sec.. hold in the reset button.. be gentle.. power on again still holding in reset.. and keep holding it in for another 10sec. You may need some help as it is hard to both hold in reset and apply power. It will show success by rapidly blinking the front led. Release the reset.. and wait a couple of min for the TC to reset and come back with factory settings. If the front LED doesn’t blink rapidly you missed it and simply try again. The reset is fairly fragile in these.. press it so you feel it just click and no more.. I have seen people bend the lever or even break it. I use a toothpick as tool.
N.B. None of your files on the hard disk of the TC are deleted.. this simply clears out the router settings of the TC.
Setup the TC again.
ie Start from a factory reset. No files are lost on the hard disk doing this.
Then redo the setup from the computer.
Since you run Yosemite in particular the following help.
1. Use very short names.. NOT APPLE RECOMMENDED names. No spaces and pure alphanumerics.
eg TCgen5 and TCwifi for basestation and wireless respectively.
Even better if the issue is more wireless use TC24ghz and TC5ghz with fixed channels as this also seems to help stop the nonsense. But this can be tried in the second round.
2. Use all passwords that also comply but can be a bit longer. ie 8-20 characters mixed case and numbers.. no non-alphanumerics.
3. Ensure the TC always takes the same IP address.. you will need to do this on the main router using dhcp reservation.. or a bit more complex setup using static IP in the TC. But this is important.. having IP drift all over the place when Yosemite cannot remember its own name for 5 min after a reboot makes for poor networking. If the TC is main router it will not be an issue.

Imac g4 dropped off home network, other still good

airport (snow) network with g3 ibook, intel imac and g4 imac. g4 was tuned off for couple days and will now not see home wireless network. airport symbol appears gray and it shows up in system profile, so i think it is functioning. in addition, the other computers, as well as this problematic g4 imac have always picked up 3 or 4 other neighborhood networks. but now this g4 imac will not see any of these other networks when the other 2 computers do.
i have tried the airport admin utilities and network assistant in preferences with not luck. the fact this computer is not seeing any of the networks that the other 2 are picking up makes me think this is a hardware problem ( card, wire). before i take it appart, are there any recommendations. thanks.

I also have an airport (snow) network with G3 iBook, intel iMac and G4 iMac. I also have been able to pick up 3 or 4 neighborhood networks with all three computers. After a recent power outage, my G4 was no longer able to see any of the networks (my intel imac and ibook G3) automatically reconnected to my home network. My G4 cannot seem to see the airport. I have run airport admin utilities and network assistant (diagnostics and assist me) with no luck. Can anyone help us?
Thanks.

OJ 6500 E709n, W7,How to change which home network computer receives scan from the printer?

Only one computer of the three on my home network can receive any scan from this wireless printer. It was the first one set up to do that.
That computer is now away at school. How can I change the computer on the network that will receive the scan?
I have tried to change the printer from the printer's Set up on the printer's face, but it only shows the one computer and I can't figure out how to change it to another printer.
Thank you for your help.

Hi AtlArchitect, and welcome to the HP Forums.
I see you are looking into connection options. Due to the age of the printer, there is not software to connect to Windows 7. You do have the option to connect with a USB via the Windows basic print driver. You can find more information here:

Name of screen shots suddenly changed

I upgraded to 10.6.0 via DVD and 10.6.3 via combo four days ago; all is well. Until today any screen shots were named
Picture 1.png and so on. Suddenly they are named Screen shot 2010-04-01 at 4.49.11 PM.png
What is going on?

Robert
For me since 10.6 I've had the behaviour you're only just seeing now. I've got a handful of macs here, 10.6.2 and 10.6.3 and every screen grab has the date and time stamp attached. For me it's normal and not a problem.
Perhaps - inadvertently/or you've forgotten - you've had a setting (somewhere) that changed this default behaviour to what you've been used to. Perhaps - deliberately - the 10.6.3 update has 'reset' the behaviour you've accepted as 'normal' to what it actually should be.
It's even possible the little man that lives inside every computer has decided on a whim to do this just to throw you loop? With it being Easter I would not rule out the Easter Bunny either.
HTH?

WRT54GS V4 has suddenly changed it's network name

I've had this router working for roughly 2 years now, and several weeks ago it started to stop logging in automatically. Today, it completely dissapeared off the available wireless list. I've recycled the power several times, and now it's back with a totally new SSID. It is the only available network. on the list. One of the times that I powered off / on, the Cisco light blinked at a very fast rate with a rather bright white light. When I checked for available networks, it showed up as an unsecured network for several minutes before the light changed to it's normal color. The WLAN light is green, and I'm sending this through the router with a cable. The DMZ light is off. The power light is on.
When I run the Net Set Utility, I get a message that the router can not connect to the internet, which is wrong, since I obviously could send you this message.
What's up with the router?
Thanks,
Steve
Solved!
Go to Solution.

As you have used this router for more than 2 years or so you should upgrade the router's firmware...Download the Firmware here
Follow these steps to upgrade the firmware on the device: -
Open an Internet Explorer browser page.In the address bar type - 192.168.1.1
Leave username blank & in password use admin in lower case...
Click on the 'Administration' tab- Then click on the 'Firmware Upgrade' sub tab- Here click on 'Browse' and browse the .bin firmware file and click on "Upgrade"...
Wait for few seconds until it shows that "Upgrade is successful" After the firmware upgrade, click on "Reboot" and you will be returned back to the same page OR it will say "Page cannot be displayed".
Press and hold the reset button for 30 seconds...
Then, unplug the power cable while holding down the reset button for another 30 Seconds...
Plug the power cable back in, and keep holding down the reset button for another 30 Seconds...
Release the reset button...Now re-configure your router...

Imac suddenly stopped connecting to network

sorry if this topic already exists somewhere. i've been searching these forums for an hour and can't find any useful help on the subject.
we bought our first mac almost 1.5 yrs ago. this beautiful 27" imac worked fine for 1 year and then suddenly stopped connecting to our wireless network. distance to the wireless router isn't an issue. doesn't matter where i move it to in the house, it sees the network, but won't connect anymore. 6 other laptops/video game consoles/pc's all continue to connect w/o a problem. this happened once approx 3 months ago and i figured our old router had kicked the bucket, so i bought a new router and it worked fine for several months and now it's happening again.
i've gone thru all the preliminary steps of unplugging the modem, the router, the imac, and renewing the dhcp but nothing helps. it will work fine if i wire it directly to the router, but i don't want to run a 75ft ethernet cable thru the house.
i'm so frustrated with this supposedly wonderful imac! can anyone help me?

Here's something to think about... I know my AT&T DSL Cable Modem will only allow a certain number of connections. A few years ago that might not have been an issue, but now with wi-fi cells, gaming systems with netflix, other laptops/ipads, you might be exceeding that limit. It could be they are all connected and you don't have a spot on the router.
This might be elementary, but thought I'd throw that out there.

I need to change the home folder name. I just bought this mac today and my cousin put his name in because he had to back up his phone while we were still at the store so he could get a new phone and now my brand new imac says his name in the home folder. This is very frustrating. I would not have let him put his name in there if I didn't think you could change it. Someone please help!

Delete his user account and create your own, using your name.

How do I change the home folder name.

I migrated my info from a Mac Pro to an iMac and now my home folder says my name and then Mac Pro. How do I change this? I tried right clicking but that does nothing, I went into the accounts tab in system preferences and that does nothing. Need help because it's annoying.

I traded for a mac; how can I change the home folder name?

Well I traded a PC for my first iMac and well...... I love it.
1. I'm running into a little problem though; I can't seem to change the home folder name to my name. Although I know it doesn't affect any of the operation of the system or my settings, it psychologically upsets me.
2. Also, is there a way to assign my Apple ID to the computer or does that not matter either?
3. I also see a little lag when trying to connect to the web, but once I do get on it seems pretty beefy, any suggestable reasons?
4. And the final question, did I make the right decision? I traded a Sony Vaio S series tablet (laptop/PC) with an Intel core i5 @ 2.30ghz for an iMac with an Intel Duo Core processor @ 3.06ghz. I've heard the numbers don't really matter but some clarification would help.

Trying to address some of your questions:
You state you are running Mountain Lion? Was that the original OS on the Mac? That is very important because:
a) if it was, the seller/trader needed to transfer the Mountain Lion license to you or it will stay with his Apple ID;
b) if he purchased ML, he is required to uninstall it before selling the machine because the license is not transferable, which means - again - that it is tied to his Apple ID (along with the machine ID).
Both/either can present some problems for you since ML is now tied to someone else's Apple ID. If you manage to "introduce" your Apple ID, it will no longer match the records MAS (Mac App Store) has, so updates or other purchases may present problems.
I would suggest that you either call Apple or book an appointment at the nearest Genius Bar and ask them how to proceed - that way you may be able to set up your own Apple ID on the machine as well as get ML registered as yours (although, as explained above, they may require you to purchase it for yourself).
Whether or not you made the right decision - well, I've never owned a Windows machine, so I can't answer your question since I have nothing to compare it with. Obviously, I use Macs...... you should be able to run your own test: just do what you normally do and see if it appears to take about the same time, is faster, or is slower.

Network name suddenly changed.

Came home and our network name has suddenly changed to "Apple (numbers and letterw) Network. Not sure why because we had no powe routage and did not reset the base station. How can I set back our original network name and password? I believe in Airport Utilities but can't seem to make it happen. Thanks for the help.

OK thanks. The reason your Extreme decided to reset itself is a mystery, but you ought to be able to get it to reappear in AirPort Utility normally with a "hard reset": Press and hold its reset button and keep it depressed, five to ten seconds or so, long enough for its LED to flash rapidly. While it starts up the LED will be solid amber for a minute or two. When it completes its startup sequence, the LED will flash amber, slowly. It should then be visible in AirPort Utility. You will then need to reconfigure it.
Before performing the "hard reset", click the Other AirPort Base Stations button:
See if your Extreme appears there.

My ipad recognizes my home network but will not connect to the internet. When I click on AirPort/preferences at the top of the imac screen it says..."AirPort has a self-assigned ip address and may not connect to the internet".How can I change ip address?

My ipad recognizes my home network but will not connect to the internet. When I click on AirPort/preferences at the top of the imac screen it says..."AirPort has a self-assigned ip address and may not connect to the internet". If this is the root of the problem,how can I change ip address?
Ipad will connect no problem to other networks.

First thing you need I think is to get your iMac connected to the Internet.
Shut down your iMac and you iPad. Then power off your router. Wait 30 seconds and power up the router.
After the router indicates that it is connected to the Internet then start up your iMac and see if it connects. If the iMac connects to the Internet then your iPad should too.
If this power up sequence doesn't work you'll have to dig into the router setup to make sure it is working properly.

I need a little help. I changed the name of my imac to reflect it's new location, but inadvertently, when I saved the change, the system unchecked the "allow this account to administer the computer" so now I can't make any changes.... I tried to reinstall the OS, but it wants me to go online while installing and use my apple id, but this is not my iMAC, so I don't want to use my account. Also, I am working in a building that will not allow me network access until I authenticate, which can't be done unless I open the browser first. So I'm stuck at this point. I can't even restore a time machine backup that I have because it gives the error message that the system encountered an error. Any suggestions?

Ask the admin/owner to sign in.

If you are using one of Lightroom's "date-based" folder templates, then the folders are created in accordance with the image capture date, not the date that you happen to import it. If you specifically want to use the import date for your folder names then you probably don't want to use the Lightroom date template, and instead you'll need to setup your folder names manually.
The vast majority of users that use date-based folder naming schemes will use a standard Lightroom template, i.e. based on the much more meaningful image capture date.
