I Lose Internet connection each time my Mac Sleeps

I have an iMac 21" late 2009 model.
Since I installed Lion, every time my Mac "nods" after leaving it a bit, after waking up it will take about a minute for the internet connection (dsl ethernet) to come back. It's frustrating, I turn on my mac to browse the web, I open Safari but then I have to sit there waiting for the internet connection to come back.
Something is wrong and it's annoying..

If you had mountain lion, you could've used a feature called power nap. It keeps networking on even when the mac is asleep.
On other OS, I guess its bound to disconnect all networks when it goes to sleep You can try an app called Caffeine that doesn't let it go to sleep.

  • My ipad mini loses Internet connection every time it automatically locks.

    My ipad mini loses Internet connection every time it automatically locks. I have to re-establish the connection but sometimes it would take too long for the Internet to be connected. I'm using a wireless connection

    just browsing around I found this question. Also on my mini retina I fight with this problem. After a lot of searching I found that the only solution is to switch to
    Airplane Mode, wait few seconds and switch again.
    Or, if you are lucky, to find a Genius who replaces your unit. Cheers

  • 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

    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.

  • Macbook loses internet connection every time it is put to sleep

    every time i open my macbook pro from sleep mode there is no internet connection, even though my wifi bars are full and black and my home router is found and ticked. after a 1-2 minute delay my mac then connects to the internet. this happens every time i open my laptop from sleep mode.  i have to wait 1-2 mins. this has only started to happen in the last few days and is driving me mad as it shows it is connected to the internet. any ideas ?
    thanks

    Delete the network from your macbook, system preferences, network, select advance tab and delete it
    Then Re join the Wi-Fi network you want.

  • Airport extreme loses internet connection all the time with imac and macbook pro

    I keep losing the internet connection with airport extreme on my imac and macbook pro but NOT with my pc

    Ok, so when you say you lose internet connection, is it disconnecting from your wireless network so there are no bars?
    And are there usually full bars?

  • Lose Internet Connection

    I thought that my new $29 Apple keyboard caused my MBP to lose the Internet connection. Not.
    I have since discovered that I lose the connection every time I shut down (or start up). I have since put Internet Connection icon in my taks bar, so I can reconnect every time I start up.
    I am using a Netgear wireless router. Any suggestion as to what I can do to keep the connection? I don't think having to reconnect every single time is common.

    Ginny, there are a number of threads over in the networking forum in the MacBook area on this topic. This seems to be a common issue on Intel Macs, and there are some workarounds. I've just been reconnecting when I boot up or move locations, and I'll wait for a fix.

  • Re-post: iMac with Mavericks loses internet connection (browsers only)

    I posted this question a while ago. Noone answered. I'll try again since this is now becoming VERY annoying...
      I have a very strange issue. My 21.5" mid 2011 iMac with Mac OS X Mavericks 10.9 has, since upgrading to 10.9 (and now 10.9.1), started to lose its internet connection from time to time (once a day).
    It has full access to the entire local network AND the VM Ware Fusion Windows XP running on the same machine has full internet access. I can use apps like Skype - but no browser. I have Safari, Firefox and Opera installed - they cannot access ANY web site what so ever. App Store does not work.
    The only way to restore the connection is to reboot the computer.
    - Re-starting the browsers does not help
    - Changing from Ethernet to WiFi does not help
    - Re-arranging the connections in Network Settings does not help
    - Renewing DHCP does not help
    - Setting the IP-address manually to something else does not help
    - Deleting the network in Network Settings does not help
    - Deleting the files "NetworkInterfaces.plist" and "preferences.plist" does not help
    - It is not a sleep issue. Sleep mode is OFF
    - It is not a DNS issue
    - The Mac OS X Firewall is OFF
    - The network settings for Max OS X and the virtual Win XP are identical except the local IP-address
    Please, someone, HELP ME!!

    Here I'm having the same trouble... Exactly the same!
    It's not a DNS problem, nor connection. All other apps still has internet connection, I can ping any domain, etc. But Chrome, Safari and Firefox are completely offline. It's terrible, because I'm always working and then I need to reboot to have internet on browsers again...

  • G4 QS 733 loses internet connect often with Comcast any ideas??

    I have a G4 QS 733 that loses internet connection through Comcast at least 2 times a day everyday for no rhyme or reason. I have had the cable modem replaced (on number 7 in 18 months but 2 were dead out of the box stupid refurbs) with a Motorola Surfboard from Best Buy and when it works it is great - 13mbps download consistently. I have a Belkin router wireless/wi-if and a PC and the Mac wired to it at the same desk with KVM and when the Mac loses connection if I switch to PC the PC connects fine so I think it is in the Mac but not sure. I have had several Macs hooked up to this same router including 2 Intel minis, several G3 towers and a few G3 iMacs and G4 towers as well and ALL had this problem at one time or another with no explanation whatsoever. I have replaced everything a minimum of 2 times now including router,modem, cables etc. and the cable drop from pole to house was replaced a few months back but no luck. Also all computers, router etc all hooked to APC battery backups so I do not think it is power related. I have no problems connecting my Pismo wiht either an Airport card or a Belkin 54g wireless PCMCIA card so I am convinced it is in the ethernet somwehow but not sure where. Anyone else have the same problems and fixed it?? Comcast is just not helpful and 14 service calls in 18 months is wearing thin at this point.

    Well just for kicks I tried running Firefox for a little over a week along with Safari and jumping back and forth between the 2, very interesting results. I have found that when Safari loses internet connection and gives "cannot find server" type errors that Firefox still has a connection and keeps right on going. I am convinced the error is within Safari but cannot pin down what it is yet. I had same EXACT disconnection issues with an Intel Mini that got so frustrating I finally sold it and it too was running Safari and I wonder if it had the same issue. Not bashing Safari but maybe there is a problem with Safari and Comcast cable that is not showing up with other internet providers or browsers ?? I am pretty sure my connection is good as all the cable wires, modem etc are all new and my PC which his hooked to the same router and shares the monitor/keyboard with the G4 never loses connection when Safari does so I think this cuts the cable out of the loop as a problem. Anyone else have similar issues???

  • Lose internet connection with TC wired

    I want to connect my TC with a network cable to my iMac to speed up the backup (time machine). But as soon as i connect the cable, I lose internet connection. I use an external modem/router from my ISP. Is there maybe an IP-adress conflict or...?
    -Reidar

    That is correct.. your cannot simply plug another router into the Mac..
    The correct way to do this is to plug the TC into the modem router your ISP supplies and set it up correctly as part of the network.
    Then you can connect either by wireless or by ethernet to the TC.

  • All devices on network lose internet connection when Dell laptop connected

    I have successfully setup my AEBS network and am using two wireless clients--HP printer and Xbox access point (both 802.11 G) and a wired iMac that also is connected via Airport (so I can move it around if i want). I tried connecting my Dell Latitude D830 wirelessly and within a few minutes of connecting the AEBS loses internet connectivity. Unplugging and restarting the AEBS restores the internet but it just drops off again in less than 10 minutes. My question is, what might be causing this and what can I do about it? One peculiar thing to me is that I am using the WEP security option since the Xbox doesn't seem to support WAP2. When connecting the Xbox it reports the network as WEP but the HP printer and Dell Laptop but suggested the network was indeed WAP even though I'm clearing using WEP security. Maybe it's nothing but wanted to add for completeness.
    The Dell is running Vista Enterprise edition.
    Thanks for any help.

    I've noticed a similar issue. Any time my HP/Vista laptop is connected to my AEBS it loses the network connection at inconsistant time intervals(~10-15 min).

  • How to disconnect internet connection in Time Capsule and reconnect without restarting the whole device?

    Hi, I would be very grateful if someone could tell me how to disconnect internet connection in Time Capsule and reconnect without restarting the whole device?
    The thing is that as I have a dynamic IP address, everytime I restart the internet connection my IP address changes. I sometimes need it to change, so I need to restart the connection. I don't know another way to restart the connection than restarting the whole Time Capsule.
    Thanks!!
    PD: the computer I use is Windows based, using the Airport Utility for Windows, but I also have a MacBook Pro I could use and an iPhone too.

    The utility in windows is very like Mac so the screenshots are from Mac as I don't have windows available now.
    How this works depends on the setup of the TC.. which you did not tell us.. you cannot change anything if you do not have the TC as the main router in the network.
    So on the internet tab you need to share a public IP address.
    On the next tab where you set IP address.
    Click the renew IP address.
    It might work.. and it might not.. the problem is you are not disconnecting the network.. sometimes the hard disconnection is required before the address will renew..
    What about unplugging the WAN port.. then click renew the IP which will fail.. then plug the wan back in again.
    In the end it is easier and faster to power cycle the TC.

  • Connecting printer to TC makes me lose internet connection

    When trying to connect my Canon Pixma MP550 to the Time Capsule, I encountered a mysterious problem: I can print from my MBP via TC but I am losing the internet connection (the DSL light on my ADSL modem starts to blink and the AirPort Utility says that there is a problem with the PPoE connection.
    Anyone having the same problem? Any help would be greatly appreciated!

    I have discovered that the problem was probably not related to the printer (even if other USB devices like memory sticks work when plugged in the TC). When trying to do a faster Time Machine backup and connecting my laptop to the TC with an Ethernet cable, the same thing happens - my modem loses Internet connection. Very curious, and to the date noone has been capable to find a solution...
