WiFi Network Locking iMac Up
I have an issue that I believe I have narrowed down to my WiFi network. Starting about two weeks ago, my late 2012 iMac started freezing up. It was happening with all apps. Eventually the apps would un-freeze, but it was not uncommon for the Mac to become unresponsive for ten or more minutes. I have a late 2013 retina MacBook Pro that is configured almost identically to my iMac and there are no issues with that machine. I took the iMac to the genius bar today to have them run some hardware tests and everything checked out just fine. So, I came home and attempted to do a fresh OS install. When I went to set up the system from scratch, it would get as far as setting up the user account and then it would lock up. I tried several times to no avail. I finally tried accessing the internet via the hot spot on my iPhone to see if maybe it was an issue with my WiFi network. There were absoutely no problems and my iMac completed the setup.
I have an Actiontec Q1000 router with a new Time Capsule. Is there anything in my Time Capsule or router settings that would be causing these problems with my iMac? It's strange that it worked just fine when I accessed the internet through my iPhone hot spot. I've never had a WiFi network cause problems with any of my machines and it's strange that it's not causing problems with my retina MBP or any of the other Macs in the house.
Any feedback would be appreciated.
Thanks, Greg
Yes, I have a Fusion drive, but this problem is new as of two weeks ago. I've had the iMac for a little over a year with no problems. This is more than just a slowdown though. It's definitely something wrong with the iMac. I suppose it could be related to 10.9.1, but I haven't read anything about other people having this issue. And, it's strange that it works just fine when connected through my iPhone hot spot.

Setting up a WiFi network from iMac... works on "old" iMac, not "new"
Hello,
I hope I'm not crazy, or even worse, stupid.
I an running two iMacs in my home office. Old one= 21" 2 Ghz PowerPC G5, purchased summer 2005 and still running like a champ. New one=27" 2.7 Ghz Intel i5. Purchased the new one July 2011. I have a cable modem plugged into the ethernet port on the old iMac. I've been accessing internet on new iMac with wifi and the internet sharing network I set up on old one. I also use wifi on my ipad and laptop. I have never had even a single dropped wifi connection on any of these devices.
I pretty much expected the same kind of result and performance when I reset the cable modem and plugged it into the new imac and took similiar steps to set up internet sharing/wifi network on new iMac. This has not been the case.
What's happening is:
The cable modem plugged to new iMac is working fine; verified with ISP. I set up wifi network on new iMac and turn on internet sharing. I locate my network name on ipad, laptop, even the old iMac, and I see the name in the list, so I figure so far so good. The signal icon appears in menu bar as usual. I open a web site to verify it's working. And it's working...for about 20 seconds. Then I get alert messages that there is no internet connection.
After creating a bunch of new networks and changing channels, changing type of security, even passwords, I realized I wasn't going to figure this out by myself. I'm not a technical person; Apple spoiled me and I stopped learning how to do anything except plug stuff in 20 years ago.
I started researching online including these discussion boards and answers have ranged from "It's the iMac! It's a hardware problem they never fixed! The aluminum case gets too hot!" to, "there's no airport card and you have to buy an external router." I gave up and called Apple, thinking surely they'd be able to give me a straight answer. Ha ha. Nope.
Of course the bottom line is I could buy applecare (haven't yet...haven't used the computer hardly and I'm still under warranty), I could buy telephone tech support, or I can take the machine to the geniuses.
I keep thinking this can't be that complicated. When I buy a new iMac--this is my 4th one--I expect things will get easier, not this complicated mess.
Oh, last I want to include I just reversed everything back to the way it was. My old iMac is connected to the cable modem and the old iMac is back to being my wifi network, sharing internet with the new imac, my ipad and laptop. Easy as pie.
I'm making an appointment with the geniuseses but hoping it's just something I'm too dumb to realize I'm doing wrong.
Thank you in advance for your patience; any help is much appreciated!SuznK66 wrote:
It never occurred to me that the wireless network/internet sharing thing wouldn't work just as well if not better on a brand new machine with the improved technologies I pretty much expect. Metal could be interfering with the signal? The machine is aluminum!! I'm no engineer but that seems kind of...flawed. I just don't understand.
I think the WiFi antenna is near an edge of the computer to avoid being encased in metal. It should work like t did in your old computer, but as I said, the use of a Mac to share an internet signal is much less common than use of a router so even if the newer computers have a non-optimal design, it might not get widely noticed in forums like these.
Sounds like AppleCare is what you want, so I'd get it and then have them check that your Mac is transmitting thru the wireless card/antenna as strongly as it should be. The antenna clearly works as you can RECEIVE a signal, but the transmitter uses different circuitry than the receiver. By the way, I think AppleCare is a good thing to get for iMacs and for laptops as they are very compact and tend to be more prone to thermal problems than other desktop computers.
I have no idea about routers aside from, of course, the apple air port one that the phone tech support guy mentioned. Are there others that are less money and just as good? I don't feel like rewarding apple for selling me a product that doesn't do what the earlier geration machines did without a problem. Seems like they shouldn't make another $200 because of their flaw. My old iMac's wifi signal was strong enough for a 3500 square foot house, 2 laptops and an iphone.
Would getting an external router definitely solve my problem? Which one would you recommend if I go that route?
I also did not understand why the Apple routers (Airport) were so much more expensive than other brands. So I purchased a linksys n router some years ago and it has worked quite well. They are very easy to configure through an ordinary web browser (some Mac folks prefer the Airport utilities that are used to configure the Airport routers, but I find the web browser interface very easy to use for the non-Apple routers), and they are in very widespread use (linksys isn't the only brand that is good for this, there are others, but I've had good experience with both Belkin and Linksys). You can get very high performing n routers from Belkin and Linksys for under $100. I'd get a router that has dual band (2.4 GHz and 5 GHz), and I think most include standard features like MAC filtering (a security measure), WPA2 security, and I thiink offering Gigabit ethernet ports would be good also in case you connect something to it like a hard drive server or a printer or want a fast local network sometime in the future.
I think the router will solve your problem and do a better job of wirelessly distributing your internet signal, but if the problem is due to a faulty wireless card (that receives fine but doesn't transmit properly) in the new iMac, I'd want to get that fixed under warranty (or AppleCare) now rather than later.
One more thing: if your wireless card in the new iMac is working properly but the physical layout is such that the internet sharing isn't working well, you OUGHT to be able to eventually get it to work by moving the other devices you are sharing with around to different locations, as eventually one should end up in a spot that works. If nothing can receive the shared internet from the new iMac, even when 3 feet away, then something might well be wrong with the new iMac's transmitter. -
I recently upgraded to version 4.1 and also at that same time changed the router on my home network.
Now for some reason when I go to use the network wifi on my phone I find that is locked.
I'm pretty sure that it has to be something to do with the router as my wife's phone is the same way and she hasn't upgraded yet.
I've tried clicking on the blue button which takes me to the next screen but can't find anything except the information for the network such as IP address, Subnet mask, Router etc. all of the fields are filled in correctly.
I tried selecting (Forget this Network) and filling in the fields that would allow it, however seeing as I was entering just the same information as the original network I didn't see any change when I re-selected WiFi Network from the settings.
I also tried rebooting my phone but that didn't change anything.
I can't find anything in the manual that was of any help so short of changing my network password and name I don't know of anything else I can try to get rid of the padlock.
I'm hoping that smarter minds than mine can figure this out.

That because you shouldn't click the arrow. Click on the name and it will prompt for the password and log you on. Clicking on the arrow SHOWS you what the router has set up for you, so by entering stuff in there you are overriding the router settings which it doesn't like - and still not entering the right password for access. -
My iMac suddenly no longer connects to wifi network when in KIOSK (username) mode, and only connects when as ADMINISTRATOR mode. Its strange because the iMac has been working fine in KIOSK mode for over a year until 2 days ago.
One of the memory cards was indeed faulty, and the other completely fine
Thanks very much for all your help!
Although there is one little thing that I've noticed. The iMac works properly, but I tried to software update to see if that may help my Minecraft sound issue (as I still don't think only having 2GB instead of 4GB would cause such a problem) but the software update application won't work. Running the "Software Update" from the apple menu on the toolbar gains no response, nothing happens. If I run the software update from system preferences, the application icon appears for a second, then disappears (as in the blank app. icon, the blank canvas with the pencil, pen and ruler in the bottom right corner). It does this every time I try to run it. It did work when the computer was crashing, but this started when on one of the occasions I ran the app. while it was crashing. Since this occured during the crashes, and still occurs now, I'm wondering did something simlar happen minecraft, as it's sound disappeared during the crashes and is still gone now.
However, the computer is now working again without crashes, which is the main thing, thanks for helping me fix the issue
Edit: I would mark the topic as solved, but I'm unsure if this would lock the topic or something simlar, so I'd rather leave it open for any ideas regarding the software update and Minecraft issues I'm having -
So far I have pulled the system configuration file, I have reset safari, I deleted all old passwords from the wifi network in Keychain I restarted both devices. I am at the end here and I cannot get it to work I have an iMac that works fine with my network but for some reason this computer will not connect. It is system wide specifically to my personal hotspot. I can connect fine to any other network (wifi) but just not mine. I have not changed any wifi settings. I have been trying to figure this out. I have a MacBook Pro Late 2006 model running Lion (10.7.5) So any ideas anyone? Please help!
12. At a WiFi hotspot, you can't get connected. The most frequent reason is the login screen for the WiFi hotspot is only able to be connected with a single type of browser. If Safari doesn't work, try Firefox, Chrome, Omniweb, or Opera.

Hi people
I need help to configure a new Airport Express only to extend the range of my WIFI network.
My ethernet cable from modem is connected directly in my iMac and I am sharing the internet by WIFI inside home very fine.
Now, I would like connect my devices on my garden on backyard.
I can't move my iMac from their place and i just want add a Airport Express between the iMac and backyard to extend the range of WIFI.
But I can't to configure to that. On Airport Utility appear the Airport Express connected directly to internet globe, but don't work.
So, what can I do? What is wrong?
Thanks all and best regards.
Carlos Sgrillo, from Brazil.The AirPort cannot do what you ask.
The Airport needs to connect to a modem, or another router......not to a computer.
The Express can only extend a wireless signal that has been provided by another Apple router. -
Hello all, I could use some help with my iPhone 4, I hope this is the best place to ask!
The Problem:
I want to do a full backup of my iphone to either itunes or to icloud. Unfortunately the iphone got wet and isn’t working properly. The phone turns on and still works, but the touch screen no longer works. I have a passcode lock on the phone so iTunes will not allow me to backup it up until I type in the passcode (which I cannot physically do). WiFi had been turned off before it got wet so it won’t connect to any known WiFi networks either to backup automatically to iCloud.
What happened:
I had been travelling for 6 months and went tubing on a river with my iphone in a dry bag. Unfortunately the dry bag failed and filled with water ruining my iphone.
What I’d like to do:
It’s an old phone and I was planning on buying a new iPhone anyway. I would love to do a full backup to either iCloud or to my computer so when I get a new iPhone I don’t lose anything. I’ve already connected it to my PC and downloaded all the photos and videos off the phone so at least I haven’t lost that, but I would like to be able to recover all the text messages, WhatsApp messages and notes I had created during my 6 months of travel.
The last time it was backed up to my pc or to icloud was in April, so there are 6 months worth of very meaningful data I would love to keep to remind me of my travels!
Is there anyway to force a full backup of the iPhone without typing in my passcode lock or is there anyway to force it to connect to a WiFi network so the phone can backup to iCloud??
iTunes recognizes the phone just now and I tried upgrading the phone to iOS7 in the hopes that it would first backup and then upgrade. Unfortunately all that happened is the phone upgraded to iOS7, but it didn’t backup to iTunes. Now the phone is stuck at the iOS7 welcome screen and I can’t do anything else with it.
Any ideas or tips would be welcome!
NOTE: This is NOT a jailbroken iPhone.If there is no other way around this, is there anyway to completely wipe the phone then??
The Apple store agreed to give me a new iPhone 4 as a warranty replacement for $150 (I travel a lot and I have a factory unlocked phone, so this is still worth it for me). But before I trade it in, I would like to make sure all my data is backed up on the device first.
When I try and restore the phone now on iTunes, it says I have to turn off Find My iPhone on the phone first before I can restore it. Now since I can't use the screen I can't really do that.
So how do I completely wipe the iPhone???
Thanks! -
Somehow a wifi network connection has been created either on my airport router or iMac or iPad which is non secured, I.e. Open. I cannot workout how to delete it or make it a secure connection. My concern is that other users may able to access my computers via this open wifi connection.
What can I do to correct this?click on the wifi icon and go all the way down to network preference click and open it once you on network window on the bottom right there is a advance icon click that then you should be able to delete all the network that your mac is remember.
hope this is help. -
My iPhone 4s will not connect with my home WiFi network. I have ios6 on my iPhone. The connection was working perfectly before I updated my IMac and my MacBook Pro to ios 10.8.2. I have had ios6 since I purchased the phone a couple of months ago. It searches for a network and finds them, but when it asks for my password, it will not accept the password. Have never had this happen before.
Hello krosebear,
Thank you for using Apple Support Communities.
If you are having difficulties connecting your iPhone to a Wi-Fi network, the following article should provide troubleshooting that should help you resolve the issue.

if I got an unlocked iPhone 4s would I be able to use a 3G network? Like so when there is no wifi network can I use a 3G network to go on the internet when i am out if I got an unlocked iPhone? Or do you have to have a locked iPhone to do this?
If I am reading your question correctly, yes if there is no wifi
you can use 3G IF you have a contract with a wireless provider
and the appropriate SIM card if required. Being unlocked does not
give you access to 3G for free; you still have to pay for it. Same
for locked iPhone. Difference is that you would have to get contract
with whatever provider the iPhone is locked to if you have locked
iPhone; if iPhone is unlocked, you will have to make a choice from
your local providers.
If this does not answer your questions, please post back with more
details and someone will answer you. -
How do I share wifi data between iMac and windows based computer on wifi network?
I have an unsecured wifi network at home and need to easily share photos between computers> I have an iMac and a couple window based computer> Is ther an easy way instead of using a thumb drive?
Since photos are typically large files it will probably be quicker with the thumb drive. The other way is to set up sharing where the files are located and directing the other computers to look there.

What could cause the lock in my preferences to seemingly to click open on there own,I use my home wifi network which is private and have never given out that password either for my network or preferences password.....help,Thank you
You're welcome.
Voicemail is left at your carrier's server. That will continue to work unless you report your iPhone as lost or stolen with your carrier.
You may never find it again and you can't if the iPhone remains offline or out of service which means the iPhone is powered off or doesn't have cellular reception. -
New 27inch iMac keeps asking to choose Wifi network. How do I stop it?
I recently purchased the new 27inch iMac and i'm really enjoying everything except this little annoyance. Everytime my computer restarts or goes to sleep, it automatically asks me to join a wifi network when I start it up again. I've already selected my home network as my default network that I want it to connect to but it keeps asking me to choose a network anyways.
If I 'x' out of the the wifi selection window, it will automatically connect to the default network it's supposed to. I just want to know why it's asking me every single time I log in.seems that the card takes a few seconds to wake up after the iMac awakes from sleep. It eventually connects to the prefered network. But the dialog box continues to show up when the the MAC is waken up...

a tech company just set up a wifi network in my house and does not use my existing TC; how do I get it in the network to serve as backup for my iMac? (I don't need it as a wifi access point anymore) thanks
Just bridge the TC and plug it by ethernet into the main router.
Bridge in v5 airport utility.
In v6 it is under network.. change it from DHCP and NAT to Off bridge mode.
Turn off the wireless.
