MacBook Pro :: It Loses Internet Connection Every-time It Is Put To Sleep
Mar 16, 2012
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.

I bought my first mac in February 2012. Ever since the beginning the Internet connection is always dropped. I have to click the wifi logo in the upper right hand corner and click turn wifi-off. I can immediately turn it back on and immediately the connection is fine again.

I am using a MacBook Air 11" (mid-2012) running OS X Mavericks (10.9.3). I'm connecting to my home LAN via WiFi connection to a TP-Link 300M Wireless router that is setup as a switch (per instructions here [URL] ...., which in turn is connected via wire (ethernet-over-power) to a Technicolor cable modem/router provided by my ISP (UPC in the Netherlands; I can look up the model number of the router if needed, but it's two floors down right now and doesn't strike me that this is the cause of the problem).Â
I have a problem that my MacBook Air intermittently loses connectivity to the internet for extended periods (minutes) even though (a) the MacBook Air maintains full connectivity to my LAN at the same time through WiFi and (b) other computers connected to the cable modem/router maintain their connection to the internet while my MacBook Air has lost its connection. Â
My test to see where the breakdown is occurring is to have four terminal windows up and running ping processes:Â
1) ping to 192.168.0.1 (my router) - this always stays live, with essentially no lost packets
2) ping to an external address (I'm using 74.125.136.94, a google.nl address) - this is my main test for access to the internet and where I see ping failures (I'm also testing with pings to other sites when the problem is occurring to ensure it's not something on the remote end).
3) ping to 192.168.0.13, which is a Synology NAS attached via ethernet cable to my main cable modem/router - this always stays live, with essentially no lost packets.
4) a login to the Synology NAS, where I am also running a continual ping to 74.125.136.94, and this external ping does NOT fail when the one from my MacBook Air does, it stays live with essentially no lost packets.Â
The problem will usually correct itself after 1-3 minutes (though the time is not consistent), and also gets corrected if I turn the MacBook Air's WiFi off and on again.Â

Just got a new MacBook Pro a few months ago. Migrated everything successfully from my old MBPro. Now, however, when I wake my computer each morning, it can't connect to the internet. It shows that my wifi is connected, but when I try to get mail or use Safari/Firefox/Chrome, it just spins until it tells me I have no internet connection. I then have to restart the computer and it works fine after that.Â
The fact that it works fine after restarting tells me it's something other than my wifi or my cable modem.Â
I'm running 10.9.3. Using 'Automatic' location.Â

My macbook air loses its internet connection after the screensaver kicks in or after it has gone to sleep.It means I have to restart the computer to reconnect to the internet, which is a real drag.I have phoned applecare who, in fairness, were really helpful but they were unable to solve the problem during my call to them.

My iMac is set up wireless. Every time it's allowed to go in sleep mode, it loses wireless connectivity. Then, when I wake it up, I must go to System preferences, Network and request it to reconnect to my home wireless network. It always does this successfully, but it's quite annoying that it seems unable to achieve this on it's own. My iPad 2 and kindle can do this, why not my iMac?

Every time I log into my imac system, i have to reestablish the network connection running the diagnostics. This only became an issue after updating the OS; I run a time capsule as my modem. This is very irritating, any recommendations?

I have 2 x 2Tb external hard drives (Hitachi Touro Desk Pro), both of which have been formatted. I am using one of them for my entire iTunes Library, whilst the other one is being used as a Time Machine back-up for the first external plus the MacBook HD.Â
All is fine with both drives until I go to use Time Machine. The external with the iTunes Library will just lose connection and I get an error message saying that "the disk has not been ejected properly and may result in damge...etc..." - just like the USB cable has been yanked out (which it hasn't). I then have to unplug it from the Mac and unplug it from the power supply, then re-conect it all for it to be able to mount again.Â
Not sure why this is happening and am getting worried that this behaviour is going to damage the drive which has all my iTunes music, TV shows & movies on it, before I get a chance to back it up.Â
Could this be an external drive issue, a cable issue or a Time Machine issue??Â

Recently my MBP (mid-09) has had issues with airport as it continually loses connection and I have to turn it off and on again in order for it to work again sometimes within seconds of doing so. I would opt for a fresh install but my dvd drive seems to be scratching the dvds and it rendered my Windows XP DVD useless when I tried to install that. So it wouldnt be ideal unless there is a method of doing so without using the dvd drive.

My 2011 Macbook pro i7 has a chronic problem: as soon as it goes to sleep, the wireless connection is lost, and has to be manually coerced back to the computer by turning the wireless off, waiting several seconds, turning it back on again, and waiting for it to find the router again. It finds the router in a few more seconds, then everything is OK until it goes to sleep again. Â
A real pain in the butt, and shouldn't be a problem on a supposedly high end computer. Â

Everything was ok until last night when I noticed this. I'm sure I didn't change anything manually in the network settings, but now I can't keep a connection for more than 10 mins. To get it back again I have to shut the airport connection (checking the diagnostics, I get a red light on the ISP circle,yellow on Internet and server) and that lasts me another 10 mins
so far I've tried sending pings, deleting this network entry and adding it back,changing the router position, but no luck. I'm able to check the router settings (tp link), but not sure what I should be looking for
the laptop works fine at my sister's place. It's just this network at home I'm having troubles with. the same thing happened all of a sudden with my imac,so I left the Ethernet cable connected to that, as it's right next to the router and it works fine.

Basically I've tried googling this problem ever since I first received my mac. Found threads, found solutions but none of them worked for me. What I'm running:
Macbook 13"
Version 10.6.4
2.26GHz intel core 2 duo
The setup:
I'll try to explain as much as possible.
#1 ISP: Telia
#2 I have a Netgear "box" which is basically for extra internet cords to be plugged into.
#3 This box, is plugged into another Netgear box (for internet cords as well) which is connected to our Modem, which is Zyxel. (Sorry, I don't have the exact models off the top of my head. If they are needed, yell at me and I'll find out the exact models.)
Quick Information about the problem: It's only the wireless that doesn't work. Well, some times. At first it worked, then it didn't (for just a few hours) then it did for a day. Then it didn't for and you get it. But it hasn't worked for months now. The actual problem: Connection Time Out. I enter the password and it 'loads' for a bit, and then gives me this error. [URL]

I use my iMac for business. So even if the mouse loses connection once a day, that it 1 time too many. Some days it loses connection 2 to 3 times a day. When it does this, I go into system prefs/mouse and it says no mouse found. Sometimes it will find my mouse, then it after searching for a minute or 2, goes back to no mouse found and searching.
Sometimes it finds the mouse and sometimes it does not. Right now, I am using a hard wired mouse. Its been about 5 minutes and its still not finding my apple mouse. In fact, this all started after I replaced the original batteries. The mouse was working flawlessly up until that point. Its a brand new 27" IMac I got Christmas 2011, so its running Lion.

I recently got a new time capsule but I have difficulties setting up the internet connection. The time capsule is connected to our WAN using a cable in my office. The computers in our organization are authenticated using their MAC address. So, I have to add the MAC address of the time capsule to make it connected to the internet. I want to connect the TC to our WAN using a cable, then I want to connect my MacBook using a wireless connection to the TC.
When I config the TC using the NAT mode (Share a public IP address), I can use the internet but I get a double NAT error and TC's LED is yellow. When I config the TC using the Bridge Mode, the led goes green. Anyway, if I connect my MacBook using wireless I cannot reach the internet. I get no error in this case so I don't know what is happening inside the TC. Interestingly, if I connect the MacBook to the TC using an ethernet cable, it works perfectly! I have added all the MAC addresses of the wired and wireless interfaces to the list of my computers.

My time capsule drops its internet connection on a regular basis. Some times it will reconnect on its own. Sometimes I have to reboot the time capsule and the computer. Sometime I have to reconfirm the tc settings and once I had to delete the time capsule setting and reinstall.
The internet is high speed pppoe and the time capsule firmware is the latest version.
All the other time capsule setting are default.

As it's a always a good idea to have an 'off site' backup. I thought of buying an external HD, setting it up at a family members house and backing up to it through time machine and an internet connection. I would prefer not to pay for a costly 'remote backup' subscription. Could someone guide me through the steps necessary to make this happen. Or suggest an alternative approach to automatically backing up offsite? One problem I can foresee is the large volumes of data involved, pictures, video etc. (even though I could do the initial backup through a 'hard-wired' connection.)

I try to use my new Mac Mini has a HTPC. However, when in the middle of watching video, say 20 minutes in a show or something, the warning keeps coming up on screen "lost connection," with the keyboard. Anyway around this? Doesn't seem like you should have to use a wired keyboard, for a computer that so many use in the living room?

I seriously need your help with an ongoing issue that's been affecting my time capsule for a few weeks now. First of all, my Xbox360 is connected with a wire to my time capsule and now, it's pretty much impossible to play any games online. In Modern Warfare 2, I get horrible lag and after a game or two, the disconnected from xbox live appears and the only way for me to get back the connection is by unpluging the Time Capsule and restarting the Xbox. This gets me a good connection for 30-45 min and after that, same problem. I don't really know what could be causing this since I also lose connection while playing a single player game that doesn't require any incoming data. Sometimes, I just turn on the console, I see the xbox icon searching for an internet connection and then nothing.
I really need your input on this because everything else connected to my Time Capsule works perfectly (PS3 and Wii wireless and a Powerbook wired). The Powerbook never loses the connection.

I searched the forum and couldn't really find anybody with this same situation. But anyways, me and my roommate both own Time Capsules, and both want to be able to connect to our own capsules, but we are obviously sharing the same internet connection. Is it possible to just plug the modem into one of the capsules, and then just plug the other capsule into that capsule? This way would there be two seperate networks that we could individually connect to and sync with?

When the computer goes to sleep, either on its own or if i tell it to, when i wake it up, it does not recognize my mouse or keyboard. The goofy thing is, the mouse will wake it, but it still does not appear to have any input into the machine once OS X is up and running again.

I leave my Air on pretty much all the time, and put it to sleep while moving around etc. Sleeping it disconnect the Airport connection - which if very annoying. At a desk I've just been dimming the display all the way off in order to keep my connection.
However, I recently noticed that by setting a "sleep display" hot corner, my network connection is maintained.
I have 2 questions:
1) Is sleep display equivalent (functionally) to simply dimming the display all the way down?
2) Is there a way to either set up a shortcut to sleep the display (other than a hot corner) and/or set it so that only the DISPLAY sleeps after 'x' minutes?

I just had the original 300 GB hard drive fail in my aluminum 24" inch iMac running the latest update of Leopard. I wasn't able to save it using diskwarrior (diskwarrior said it was some sort of mechanical failure) but I was able to recover most of the data from it by booting from an external hard-drive.
So I went out and purchased a brand new Western Digital Caviar Black 1TB drive. The install went fine, it found the drive partitioned it and installed Leopard successful. Then is crashed and disappeared when I left it alone to run all the software updates. I came back and the computer was stuck on "Restart Required" after downloading all the updates. I went to hit restart now, and the system just hanged, wouldn't do anything. So I hard powered down the system and restarted it. It came up with nothing, just stuck on the White Screen of Death. So I plugged the external drive back in and booted from it. Mac OSX couldn't find the drive and diskwarrior would crash if I tried to run it. I tried to boot up from the OSX start-up disk and it couldn't find the drive either.
So I took the case apart and made sure all the connections were solid and the drive was mounted correctly. Everything looked fine so I plugged it in and it started up fine. Finished the updates and the iMac ran great.
So I thought maybe it was overheating, so I've installed smcfancontrol and started to monitor the temp of the drive. I also took the mac apart again and sucked out any dust in the fans or vents. The drive never goes over a 105 F, so it doesn't seem to be overheating.
However, this is where the problem is consistent: everytime the iMac goes into sleep mode, it crashes and the iMac is unable to find the hard-drive again. Unless I unplug it completely for 5 minutes or so. Once I unplug it, it finds the drive and operates like a champ.
I think maybe there's an issue powering the drive back on? Anyone have any ideas?
And my follow up posting later that day:
Quote:
So I ran some tests just to see if was an overheat issue, hard drive malfunction, or sleep issue. I decided to start encoding a video, pulled up Word, Power Point, Excel, started downloading all 6000 mail messages off my server (I never delete my e-mail :-/), also started installing iLife 09, and pulled up a bunch of webpages in Firefox with multiple tabs.
However, I shut off all sleep mode options on the hard drive. I let it run for an hour and came back. Everything is fine, hard drive isn't locked up and smcfancontrol shows the hard drive running pretty hot (115 degrees) but not so hot I'm worried. So it's definitely something to do the hard drives going into sleep mode and not powering back on. It's also weird that I have to leave the computer completely unplugged for 10-15 minutes before the drive is recognized again.
So turning off sleep seems to be my work-around, however, this shouldn't be a long term solution. I'm worried that there is a bigger issue with the iMac, but I'm not sure what would cause this. I've been a PC guy for years, this was my first Mac, and honestly I don't know enough about the inner workings to narrow this down. I would assume this would have to do with the motherboard in some way? But I'm not sure how you would even test it.

I have a MacPro Early 2009, 2 ethernet ports.Ethernet 1 is connected to the LAN and Ethernet 2 is connected directly to a SSL Matrix console (an audio mixer), whom driver needs the used ethernet port to be first of the list in the Network connections list in System Preferences.So when I browse internet I can't use the Matrix's software, and vice versa.I had to create 2 different network positions to browse internet and to work with SSL Matrix, one with Eth 1 first place, another one with Eth 2 first place, and I always have to swap positions.Is there a way to force OSX to use by default the 2nd connection of the list for internet access?Â

I'm on holiday using my mobile phone (Nokia N80) to connect to the Internet over GPRS / EDGE / UMTS. Everything works like a charm, but often the Internet Connect applet drops the connection and just hangs disconnecting.
I'm running OS X 10.4.7 on a 17" Macbook pro, but I have the same result on a iBook G4, same OS X version, and even trying with a different mobile phone (Nokia 6600) and different network service provider.

My Mac Mini loses connection with my Onkyo receiver NR-609 after turning off the receiver then back on. The only way to reistablish the connection is to unplug then replug the HDMI cable to the Mac Mini. There's no effect if I unplug then replug the HDMI to the receiver.

Problem with Time Capsule acting as a router for home Internet connection. It would lose it's WAN IP address after 5-10 minutes, sometimes longer. Rebooting the Time Capsule would fix it temporarily. Also, renewing the DHCP lease for the Time Capsule using the Airport Utility would bring it back instantly. It's a 500 GB Time Capsule and has 7.4.2 firmware. An update check says that that's the latest. I tried a factory settings reset. At first I thought it helped because it lasted more than 20 minutes afterward. But then did the same thing again.
Some background: Time Capsule faithfully did it's duty at another home for extended period of time without any known issues. At old home it was connected to a different cable modem - an RCA I believe. At the new home it's connected to an Arris modem that provides data and voice. For the first three or four hours it worked without issue, then it started losing it's connection (right about the time I was leaving )
The cable company tech had me believing that I had a glitchy Time Capsule. Now I think I have either a:
- incompatibility between the Time Capsule and the new Arris Telephony cable modem
- network conflict on the cable company's side of things. The Time Capsule was running connected to a different modem at a different address (and account, I believe).
- final choice is a glitchy Time Capsule.
(I first wrote this post on 9/30/10, at that time firmware 7.4.2 was current, now 7.5.2 is latest. I'm attempting to recreate the problem now. This happened at a client's home with their setup - I'm now hooking it up as my main router and using the same Arris Telephony modem. It's been running with my Arris Telephony modem on my Internet connection for over twelve hours without issue).
