My imac loses wifi connection when it goes to sleep, how to correct?

My iMac loses wif connection when it goes to sleep.  How do I correct?

Are you running OS X Lion? If so there are unfortunately numerous threads on here discussing exactly the same problem. So far there doesn't seem to be a definitive solution, with everyone hoping that Apple will come up with a permanent fix.
Here's a quick search of these forums alone - depressing reading:

This 'fix' has worked for a few people but, unfortunately, not everyone:

  • 7510e printer loses internet connectivity when it goes to sleep

    I own a 7510e all in one printer, I connected it wireless again after having it connected with a USB
    cable, I had to do this because my printer loses internet connectivity when it goes to sleep or if I get a power outage, this has been going on since I purchased it last year. I got a new wireless router/modem combo from my ISP server and hoped that would solve the problem but it has not.
    I cannot get any apps except for those that are on the front of my printer which are just for small kids. I am now told that this printer has been discontinued and 7520 has replaced it, I do not wish to spend another $200.00 in less than a year for a printer. It is registered with HP connected and I have a Efax # and HP connected address, I did everything correctly but it seems that each time I set it up wireless it messes up my desktop windows 7 home premium 64 bit, cloud services told me not to use  IE 10 but we are ready to download IE11 so I am using IE 10, this time HP support assistant quit working and I could not even uninstall it until I downloaded microsoft fix it and then redownloaded it from HP web site.
    If anyone has any ideas I would appreciate it, I am not on a home group yet it always tells me I do not have administrators permission to do a lot of things, I am the only user.

    Hi emma22
    Here is a document for Getting the Latest Firmware and Product Updates.

    I checked and there is no way to turn off the sleep mode on this model.
    I included a document for Printer Does Not Maintain Wireless Connection and to try Solution three: Assign a static IP address to the printer. You will need to get your It department most likely to set this up for you if you don't have full admin rights.

  • Printer loses wireless connection when it goes to sleep?

    My printer loses wireless connection to my router when it goes to sleep and I have to input the WEP key again.  As long as the printer is awake it works fine.  The wireless light remains on.
    Printer is HP Officejet Pro 8500A Plus and the router is a Verizon 7500.

    If you mean WPA, that is good.
    Let's set a static IP address for the printer:
    - Print a Network Config Page from the front of the printer. Note the printer's IP address.
    - Type that IP address into a browser to reveal the printer's internal settings.
    - Choose the Networking tab, then Wireless along the left side, then the IPv4 tab.
    - On this screen you want to set a Manual IP. You need to set an IP address outside the range that the router automatically sets (called the DHCP range). If you do not know the range, change the last set of numbers (those after the last '.') to 250
    - Use 255.255.255.0 for the subnet (unless you know it is different, if so, use that)
    - Enter your router's IP (on the Network Config Page) for the gateway.
    - Enter 8.8.8.8 for the first DNS and 8.8.4.4 for the second DNS. This is Google DNS. You can choose another external DNS if you wish.
    - Click 'Apply'.
    Now, shut down the router and printer, start the router, wait, then start the printer.
    After this you may need to redo 'Add a Printer' using the new IP address.

  • My brand new iMac loses its WiFi connection when it goes to sleep, does anyone have a proven fix?.

    I have a MacBook that is about 4 years old and a brand new iMac both are running the most up to date version of Lion.  My old MacBook has no issues; however, my iMac loses its WiFi connection every time it goes to sleep.  There are some discussions about this already out there but does anyone have a proven fix.  This is very frustrating.

    I was having the same problem for a long time.  I tried everything but nothing seemed to make it stay connected.  It was very frustrating.  I just got a new Airport Extreme.....bang!.....all better.  Problem gone. 

  • Airport drops my connection when it goes to sleep

    My iMac always drops my connection to my network when it goes to sleep How do I fix this?

    I have tried some minor fixes I saw recommended. Last tried was deleting 6 plist items from library. I have to wait and have it go to sleep to tell if it works.
    I have 10.8.2 running on my imac. I have to go now but will check thus discussion upon my return.  Thanks   John

  • Wireless losses connection when it goes into sleep.

    I'm using a Linksys Wrt54g router. Not a major problem since all you have to do is click the Airport icon and restart but why do it does it do this? My iMac flat panel doesn't do it.

    I have the same problem at my school. I have about 50 eMacs (1.42) using OS 10.4.5 and I have 3 eMacs that lose the airport connection when they go to sleep. I have tried several things but can't find the problem. Each computer is in a different room and the other 3 computers in each room stay connected. Please help.

  • HP dropping connection when it goes to sleep.

    I am running Windows 8 and my new HP Photosmart 7520 keep dropping the wireless conection when it goes to sleep. I see posts all over the net. Has anyone figured out the problem yet. I've tried scan doctor, no help.

    Hi Swenn,
    I would recommend following the document below - although you can skip the print and scan doctor until later, as you've just tried it.

  • IMac loses WiFi connection after waking from sleep on OSX 10.8.2

    Bought a new mid-2011 21.5 inch IMac this week. It is not re-establishing WiFi connection after waking from sleep. Was happening on OSX 10.7 that it came with, so updated to 10.8.2 and same problem exists.
    I am running a mid 2012 MacBook Pro with Retina Display alongside, on OSX 10.8.2 and no problems at all. Cannot work out what is causing the IMac to fail and neither can Apple!
    Could it be the Netgear Wireless Router 3 years old? Full signal strength!

    Me too!
    I am on a MAC Pro desktop and I am having the same issues. I go to system preferences and just click the network icon. Then I close mail and when it opens it now sees the network. This is getting very annnoying. 

  • Mac mini loses wifi connection when using vnc....

    I currently dont have an aextra keyboard, mouse and monitor so for short term id like to connect remotely to it. I configured the sharing settings in system preferences on my mac. Im running Mac OS X Lion 10.7 and Im using tightvnc on my windows computer and its having a hard time getting connected to the mac mini. I notice when I try to connect my wifi connection on the mini drops. Can anyone tell me why this is? Any help would be greatly appreciated.
    Thanks
    Angelo

    We'd need a Monitor & KB/Mouse on the Mini, or another Mac to log into it, but you might try navigation to...
    /private/var/log folder on the Mac & maybe look at the system.log if you can on a PC.

  • Apple TV loses WiFi Connectively After waking up from sleep

    My Apple TV, software version 3.0.2 (which gives us 1080P btw), works fine, until I put it to "sleep." Later, when I use the Apple TV, it says: "Not connected to the Internet." In effect, my wifi has disappeared from the memory of the Apple TV, and I have to enter the wifi network's password again on the Apple TV.
    I have had this Apple TV for about a year; the problem appeared maybe one month ago.
    I took it to the Apple Store after Apple Care Telephone Support consulted with engineers. The Apple engineers said it could be a hardware problem, and for me to bring my Apple TV to the Apple Store so they could diagnose it. But at the Genius bar, they put it to sleep and woke it up and it never lost connectivity every time. I suggested that as the Apple Engineers wanted the hardware looked at, why doesn't the Apple Store keep my unit, put it to sleep, and wake it the next business day? The genius bar refused, as the problem did not replicate itself at the genius bar. I told them that trying after 10 minutes wasn't enough. They should try it overnight, as I do (go to bed, try it the next day, only to discover that the Apple TV lost it's connection to the WiFi.
    So for now, my work-a-round is that after a few hours, I have to reenter the password for the wifi. I've been reading threads about similar issues with the iPad, but I don't know if the problems are related (technology wise).
    Bottom line: My Apple TV loses its connectivity after being in sleep mode for awhile. Nothing to do with the iTunes store or 3.0.2 as far as I can determine; if I don't put it to sleep I don't lose connectivity.

    Thank you, Jamie Cox1. However, after rebooting the Apple TV, I lose my 1080P; it goes to 720P and takes about 5 minutes or so to reboot. Then I have to set the 1080P again. The good news is that the wifi returns But it is quicker merely to re-enter my password.
    The problem remains: After a while of having the Apple TV in sleep mode, I lose connectivity to my wifi And while I have a complicated password (upper and lower case letters, numbers, and not a dictionary word), it still is quicker to re-enter my password than to wait for the Apple TV to reboot and re-enter the settings for 1080P.
    Thanks anyway; if I only had 720P perhaps this solution might be enough - but I have 1080P.
    I am working with Apple Care; I have reconfigured my wifi twice with Airport Utility, removed all interference (microwaves, cordless phones), and still the problem remains. Apple Care hasn't solved the problem. The Genius Bar at the Apple Store hasn't solved the problem. Re-booting does find the wifi again, but it takes a long time, and then I still have to re-set the resolution to 1080P. So I just re-enter my password each time.
    And that's my update! I appreciate everyone's suggestions. However, the problem remains: after putting the Apple TV in sleep mode, and then later when I want to use the Apple TV, the Apple TV forgets that it is connected to wifi and I have to re-enter my password, or I can take some time and reboot the Apple TV but then while the wifi returns, the 1080P disappears.
    Thank you everyone for all your suggestions
    But the problem remains

  • New 6500 E709n loses wireless connection when it or laptop sleeps... & other problems!

    Just got this printer and am hoping we can get it to work because we really like it.  I believe we've done everything right - it is connected to PC via USB, and to laptop via wireless network.  Both computers are Dells running XP.  Our wireless router is a Linksys Wireless-G WRT54G.  We installed the disk on both.  Immediately after installing on the laptop by plugging in USB and then unplugging, we were able to get it to work.  We printed and scanned from both . . . UNTIL the printer went into power save mode.
    When it sleeps it loses all the network connections (but will still print from PC).  Even the icons disappear from the laptop after it sleeps.  The only way to get it to work with the laptop again is to start all over, plug in the laptop, enter the WPA key again, and so on.  Then it's finebut for just a short while.  Now, when I registered my protection plan, I was on the phone with a techie guy and asked him if it's normal to have to keep entering the key every time you want to print, and he actually said that maybe I shouldn't let the printer sleep - wow! I want to conserve energy, so I may even want to shut it off, okay, and I don't feel I should have to go through this rigamarole every time I want the darn thing to just be available to the network.  Furthermore, what's the sense of having to turn "Wireless Radio" on and off all the time???
    Anyway, there are other problems and the menus in the internal web browser is about as confusing as it can be.  Is the passphrase the same as a WPA key?  There's a passphrase in there which I did not enter, and I don't know what it is because it's been disguised with dots.  When I enter the WPA key on the front panel of the printer, it doesn't stick.  One thing I noticed in the instructions is to keep telephones away from it, so I moved ours (was right next to it) but it's still being ornery.
    In addition, the scan function only works from the software, not as a standalone if I use the front panel.  When using the button on the front panel, sometimes it sees the laptop, sometimes it doesn't, and then it starts to scan, but a menu pops up on the computer asking to update the buttons, and then nothing happens.
    Have we a clunker on our hands that should be returned, or is there a remedy?  All suggestions welcome!

    Let me answer the easy stuff first:
    Yes, the passphrase is the same as the WPA-PSK key.
    No, it's not normal to have to re-enter the wireless security key over and over again.  Politely tell our service agent that he is mistaken on this point.
    There's no sense in having to turn the radio on and off all the time to get the printer to remain on the network.
    When the printer goes into power-save mode, can you still access the printer's internal web page by browsing to it's IP address?  When the printer loses wireless connectivity, can you wake the printer by pressing any of the buttons on the front panel?
    I have a couple more questions:
    What WRT54G HW version do you have (it'll be on the bottom label of the router)?
    What version of FW does your router have?  You'll have to browse to the router's internal web page to find out.
    Finally, change the WPA-PSK group key renewal period to the largest value possible.  Tell if this affects the frequency of printer losing Wi-Fi connectivity?
    One more question.  After you have the printer connected to your wireless network and it's working, if you turn the printer off (via the power button), wait five seconds then unplug it then plug it back in and turn it on, does it connect to your network?

  • Apple TV 3 drops network connection when it goes to sleep

    I updated my Apple TV 3 to software version 7.0 (based on iOS 8) and now every time it goes to sleep it shuts down the network connection.  To wake it up, I either need to use the remote or use an iOS 8 device that supports handoff.  At least I think it does since my iPhone 5s can wake it up, but my iPad 2 cannot.  I believe the Apple TV is now using Bluetooth for connections.   This basically means Airplay with older devices won't work without first waking the Apple TV.  I'm not sure the point of the change since I'm using Ethernet, not Wifi, so there's no reason to "power down".
    on a side note, sometimes the iPhone 5s can't wake the Apple TV either.  It usually wakes up when I open the control panel, but not always.  It goes back to sleep when I close the control panel. 
    Ia there any setting to make it work the way it used to?

    the WIFI does not drop when my appletv goes to sleep.
    my iphone can still see the appletv (via the airplay icon) when it is asleep.
    All you are seeing is the last known Wifi state in iTunes (and similar app in iPhone, iPod, iPad). The AppleTV however has powered down "something" in its own mechanism to conserve power.
    For the Apple TV to use such low watts in operation, its got to be powering down something.
    I have seen this behaviour before in other devices that try to power down Wifi in a sleep state. It is not connected but it thinks it is. I'm not an expert in Wifi technology so won't state what is happening behind the scenes but do know that re-starting/re-powering up the devices will cause the wifi connections to be re-established.
    I would try this but don't have access to my ATV at the moment. Turn off encryption and see if the problem persists. My gut tells me that the WPA/WEP encryption has lost itself in the low power state.
    I suspect that 10/100/Gig RJ45 ethernet connections are not affected.

  • Wifi turns off when screen goes to sleep - how can i disable this?

    running 10.8.4 on MBA 2013
    is there a way to keep wifi alive when the screen goes to sleep (automatically turns off)?
    this is very annoying that i would have some internet connected application running (eg. a download) and then the screen turns itself after a timer and also cuts the wifi. this means i have to keep my screen on if i had a big file to download. is there a way around this? i cannot find any settings addressing this issue/option.
    thank you.

    edit:
    i know there's the option "prevent computer sleeping when screen is off" under power adpter, but i would like it done while running battery.
    thank you.

  • Looses network connection when computer goes to sleep... and password ques.

    So... I browsed the forum (not too in depth...) and have found anything to help me on this issue.
    When my computer goes to sleep I lose my connection. Even when I was testing it out and put it to sleep for five seconds it happened. So every time my computer goes to sleep I have to reconnect to my network and re-mount my external HD. Every time. And on top of that... when I type in my WAP password to connect... I check the option to save the password in my keychain and it never saves it. It saves the password to connect to the external HD, though... just not the network.
    Anyone have an idea?

    The keychain is pretty much a central place that stores usernames, passwords, and some kinds of cryptography information (certificates and keys). OS X provides an interface so it's easy for programmers to make their applications use the keychain. That way, all of your passwords are stored in one place. Useful feature, that.
    Keychain Access is used to access things in the keychain. So if you have a program that doesn't use keychain, you can use keychain access to display the password for various things you've long since forgotten.
    Keychain access is also useful for double-checking that something is in the keychain - or for removing things that are already there that you don't want to have in the keychain.
    As for two passwords for your network - that sounds correct. One is for the network, and the other is for the AirPort Base Station. Keychain Access has the "kind" column, and there are two kinds of entries:
    AirPort Base Station Password: This is not used to access the network - it's used to configure the base station.
    AirPort Network Password: This IS what you use to access the network.
    Though your mention of "login" and "system" passwords is making me think you may be talking about the passwords for the "system" and "login" keychains.
