OS X :: Losing Wifi Settings In Keychain?
Dec 26, 2010
For some reason, approximately once a month, the Mac loses the wifi settings. This sends the clock back to January 1st and takes several attempts of reentering the network name and password before it is recognised again.
Also, the wifi settings seem to no longer be part of the keychain when that happens.
This is getting to be a pain. Does anyone know why this happens (it only happens on one of the Macs; others are fine)? What can I do to repair it for good?

I have a G5 Duel 2GHz Power PC, Recently I was losing the time, date and wireless settings so I assumed as my machine is now 4 years old the PRAM battery was up for renewal.This has now been replaced but I'm still losing my settings, not all the time but randomly, sometimes I lose my wireless key sometimes I lose time and date sometimes both, this can happen daily.
I have removed the (New) Battery and checked the voltage and it reads 3.6 Volts, I haven't checked this under load though, so presuming that the battery is OK, what else could cause this.. a failing System Board?

Does the login keychain have anything to do with the iTunes authorization required to play iTMS purchased music? If so, how do I reset the keychain without losing it?
The problem is that every so often the login keychain pops up asking me to enter a password. I've changed it and the keychain did not so they are out of sync. The only solution I've found was to delete the keychain. In 10.4.11 there doesn't appear to be any other way to sync the login password with the keychain password. Furthermore as I do not remember my old dotmac password nor my iTunes Music Store password, and as I no longer have access to either the Music Store nor dotmac, I worry that reseting the Keychain would lose access to all the music I've purchased throughout the years, and that's a lot of money spent for me to lose it.
The problems these brilliant people created are just so stupid I shutter to think what else they're messing up. I realize it's my fault for having to reset the password (even though it's a system bug in Mac OS X), but how do I resolve this problem?

Stayed with 10.6.8 for years and had no issues, then started to see problems with Safari, websites not loading, email problems, updates no longer available etc etc. Â
So I used Carbon Copy Cloner to make a backup, wiped everything, then a clean install of Yosemite. All went very well indeed!Â
I have 3 accounts setup on the one iMac (2011 model i7 Quad core). 2 of these accounts work perfectly, but the thing which is driving me nuts is on the 3rd account. I set the mouse tracking speed and remove the scroll direction tick, but whenever I log out, it resets itself! Every time I log in, I have to go to System Prefs and reset it all over again!Â
The solution is to setup another account of course, and copy all files over, but I'd prefer to work through this issue to find out whats causing it if I can.Â

I have 3 macs working off my wireless router. Two out of three are still working fine, but the third (an iMac G5) keeps losing its network connection and either won't find the network or, if it does, will not allow me to rejoin it, even after entering the relevant key/password. It has been in the same location in my house and has worked fine for the last five years. But oddly, if I move the G5 to within a few feet of the router it starts working again (though sometimes seems unable to find the network, although when it does it will let me join it, hassle free).Â
Have spoken to some Apple guys and, following their advice, have gone into SYSTEM PREFERENCES, NETWORK, LOCATION but having got that far a pop-up appears telling me that an application has changed my network settings. Zapping OK, this dialog box just keeps re-appearing and the only way I can get out of this corner is by 'force quit'. Â

I'm using a Mac Mini (running 10.3.8) connected to an old View Sonic E95 monitor. No problems except that every time I leave the computer for a while it goes to sleep and "forgets" what display it is connected to. When I hit a key or whatever to reawaken it, the display resolution has been re-set to "VGA 800x600" and I have to tell it to "Detect Display" again..
Any clues? I have looked on the forums and Google with no success .

I am running an imac 24-inch Mid 2007 on 10.7.3. Always do the updates and everything seems ok. I have been having problems with connecting, reconnecting after sleep and just losing my connection in the middle of being on wifi. I have replaced my wireless router, I have deleted all previous wifi networks. I have also renewed my dhcp license. Nothing works. To reconnect, I have to continuously go to network preferences, assist me, diagnostics, then continue with the assist me and choose my network and it then reconnects. This is not just waking from sleep. Sometimes just randomly while working on the computer. I have read some things about equipment plugged in and I have an ATT micro cell plugged into 1 ethernet jack in my wireless router/modem, I also have a bluetooth mouse, a printer plugged in USB and a Lacie HD using Time machine.

Since upgrading to Lion I've had the problem with wi fi losing connection and this seems to be common?The Apple support talked me through a change in system config. I'm no expert and not sure if I could repeat if needed.The support desk could not guarantee that this will permanently fix the problem though.

Every time I try to delete my wifi certificate in Keychain Access, it continually crashes. Tried it in safe mode, still crashes. I cannot get my Airport extreme 5th gen to pass along an IP address to my Mac even though mac is connected to AE (seen via Network Utility). Thought that deleting keychain password would work.  OSX 10.10.1  retina Macbook Pro 13

For several weeks I've lost internet connection on my iMac every day or so; the wifi icon changes to show a ! and is otherwise greyed out. My internet connection is via a relatively new Time Capsule (2011) which has an ethernet cable connecting it to my Sky broadband router. I moved to this new Sky broadband router in early Jan 2012 (changing to Sky as a Broadband provider) and it works nicely as a router. My iPhone, iPad, AppleTV and a range of other devices (including an Apple Airport Express connected to a Sky TV HD box to enable it to download movies) have continued to work on the internet without problems.
The IP address of the iMac (27 inch quad core i7, 8 GB RAM, fully up to date on Lion) disappears from the Network settings when the problem arises but the connection of the iMac to the wifi (and backing up to the Time Capsule) still works. I can even use a VNC app on the iPad to connect to the iMac on the same wifi LAN when the IP address has gone and the ! is showing in the wifi icon on the menu bar. To get reconnected to the internet, I just restarted the iMac and it was then back accessing the web nicely. Eventually the iMac would not connect to the internet at all. It would momentarily get an IP address from the router and then lose it again. I then tried taking the iMac to the Apple Store.
Various diagnostics run in store at Genius Bar and during the week and the problem (using the same account) was not replicated. On its return home, it was still not working on the internet. I then tried booting into 'safe mode'. This enabled a stable and reliable connection to the internet! After several days in this mode, I re-installed Lion and booted into normal mode again. The problem returned and has been with the iMac since. However, at least a restart of the iMac gets it straight back on to the internet again. I suspect some sort of corrupted network preference file or the like. But where? The disconnection from the internet can happen any time of day; for example it happened while typing this message but more often than not it happens when the computer is unattended.

I just got a brand new MacBook and I connected to my neighbors network (its ok with them) and now I bought a router and it works but every time I open my MacBook, it automatically connects to theirs and not mine. How can it forget a Network?

I have a MacBook with OS 10.7.4 and use Safari and the Wi-Fi connection to access the internet. The computer will not save Wi-Fi settings from one session to the next. When I start up only the left side of the menu bar is displayed, and does not show the right side containing the connection icons. It will not allow me to access System Preferences, will not load Safari, and will not let me make any configuration changes. When I shut down the computer (some times as many as 3 times) and start up again it shows everything and works OK. The network was created on an iMac which shows everything to be normal.

I have to work with two different Wi-Fi (at home and office) one of which uses DHCP and other requires me to manually enter IP address. Right now I have to keep on changing Wi-Fi settings (putting IP addresses when at office and setting to DHCP at home) whenever I go from home to office and then do the reverse when I go from office to home. Can I automate that so I don't have to repeatedly fiddle with settings?Â

I got a HP Photosmart C4380 all-in-one wi-fi printer and i want to set it up on my wireless network. so i plugged it in to my MBP via USB and ran the HP setup assistant that came with the printer.
at the first step it recognized my printer as being connected via USB the next step when its supposed to detect your wireless network i get this message that says your printer is not connected to the computer, connect via USB to save settings.

I have one mcbook pro running on Lion.
I am using at work a wifi connection that requires fixed ip and specific proxy.
When i go home, i am using another wifi network, so every day i have to change the advanced network settings of my mac.
Is there any way to attribute different advanced settings for each network and save it, so it will be changed automatically?

There is a problem of a periodic signal loss. The reason for this is the password reset network settings in the airport. It happens randomly during sleep. The system log says only connect and disconnect from the network. What may be the reason?

I just downloaded the PhotoSync app onto both my iPhone 4 and MacBook Pro (Snow Leopard). However, when I try to use PhotoSync to sync all my photos from my iPhone to my MacBook Pro, I get an error message telling me to check my wifi settings - even though both of my iDevices are connected to the same wifi network. I get the same error message when I try to use PhotoSync to sync the pictures from my iPhone 4 to my iPad 2, as well.

I have a Time Capsule wirelessly connected to my iMac. Since I've encountered some problems with backups because of intermittent wifi connection failures, I want to switch to a wired connection with an ethernet cable. I know I could fiddle with the wifi channels etc. but since the TC is just sitting next to my iMac anyway, I could profit from the higher bandwidth of a wired connection as well.
Two questions:
1. What exactly do I have to do to make the switch? Are there any new settings I have to apply? Create a new network?
2. Will I still be able to use the wifi connection to get on the internet using my smartphone?

I'm sure this is a very basic question, but having just made the Mac switch a week ago...I am lost. when I did a forum search, I found out how to access keychains, but I'm not sure if I found something particular to my question- please forgive me if I overlooked something.
I was downloading microsoft software last night and all of a sudden I began getting these little pop-ups that say "A keychain cannot be found for safari" with the option to cancel or reset to default.
how can I fix this so it doesn't happen?

Safari keeps giving me popup windows saying a keychain can't be found. It's only just started doing this but it's really annoying. Could it have anything to do with the fact I installed a new flash player? That's the only difference I can think of.Also on another computer it keeps asking for a password to access the keychain. It only does this on one user account though. Any assistance is gladly accepted!

I've never used OSX before about a week ago, but I am picking up on it well (I've used GNU/Linux for almost ten years so I know my way around an operating system). But I don't really think keychain access is working as it should...It's hard to explain. I mean, the way I understand it, shouldn't it be saving the passwords I type into Safari and auto-filling them? Because it only auto-fills some passwords. Paypal autofills, but my bank's website doesn't, and even this forum doesn't autofill. I have to type in my password every time I visit.
Is this working as intended? Is there a way I can get Safari or Keychain to fill in all passwords for me automatically? This is leopard on an iMac G5 iSight model. I did a fresh install like a week ago. Sorry if my question is vague but that's the best I can do with the amount I understand.

I'm able to look at all my keychains, except Private Encrypted Data. Any ideas why? I've used my Mac password on every keychain, but this one I just can't open.
