Losing ethernet connection

I am losing the ethernet connection every time I close the lid on the macbook and then reopen it later. I have to wait about a minute then unplug and replug the cable to get its status back. Does anyone know how to avoid doing this?
thanks,

One thing that can work, try this, please ignore the exact symptoms and connection and Hardware types, it's worked for many others than the stated...

  • Is anyone being bothered by constantly losing ethernet connection?

    it's driving me insane. i'm in full-bore troubleshooting mode.
    any clues i can and/or should follow?

    it's losing it.
    the cable guy has been here twice. at one point he was playing around on my computer waiting(again) for it to happen (again and again) and he turned to me and said "How can you stand this? It's driving me crazy now too."
    then he talked with the Apple specialist at the cable place who said i had to contact apple because i shouldn't be losing ethernet, and he knew i was. so i contacted apple who told me to update to the current os (10.5.11) and I told him I was afraid to and he knew I had a previous complaint about 10.5.10 and was back on .8 just for my own peace of mind, so i DID update without incident and STILL I keep losing Ethernet. It's ruining my life now. not just bothering me.
    So, I will call Apple monday, after researching users between now and then so I don't feel alone or know that i am alone for the next troubleshooting session. i have to get to the bottom of this because my warranty expires in Nov (I think...or maybe Dec.) and I am WAY TOO FAR from an Apple Store to take this lightly. I bought a laptop just because of the problem I had getting my desktop iMac fixed, which I miss, because it is CRT and as a graphic artist that is important to me and yet it is still broken.
    The cable guy said "Worse comes to worse, if you go wireless, it won't matter any."
    however, that might be a last resort AFTER my warranty expires and I'm stuck with a bum ethernet plug on my machine...which might be the case.??????

  • Mini Server losing ethernet connection to FiOS ONT

    I have Verizon Fois which has worked flawlessly with either a Verizon supplied Actiontec router or a Time Capsule connected to the Verizon ONT (optical network terminal) ethernet.
    I recently bought a mini Server to connect to the ONT directly to be my NAT, router, file server, etc. The mini can use DHCP to initially get an IP via DHCP, but it will lose it over time and revert to a self assigned IP. I have worked this with verizon tech support and their network engineers say that the ONT is fine but has only a one-way connection to the mini when it is in the bad state. I have used a tried and true cable which is not the problem. The mini has had one trip back to a genius bar and they reinstalled the OS and could not reproduce the problem.
    I am about to resort to chalking it up as a weird mini ethernet hardware problem unless anyone has another idea. As I see it my next plan of action is to ask for a mini replacement to see if it helps.
    Thanks for any ideas or suggestions.

    Just like the KB said, the only way to get reconnected is to turn AirPort on and back off.

    It may also be in the developer tools. I can't remember where I got it. After downloading it. I modified it for my purposes and then had it launch when I logged in (Startup Items). It did the job, but every time the connection goes down, you do have to let the script do its thing, interrupting your work. However, at least it does it automatically.
    I finally fixed the problem by getting a new Santa Rosa MacBook Pro. Works like a charm.

    Absolutely sure.. There is no connection at all.. reset is only the router side of the TC.
    For the hard disk to be erased you need to access the airport utility disk page.. request erase and confirm the operation.

    Thank you again
    I am uncertain why if you have access you cannot change settings.. but that is why you reset things so any of those problems should be fixed.
    Here is the Apple info on reset.
    http://support.apple.com/kb/ht3728
    And here is the quote from the horse's mouth so to speak.
    Factory default reset: Perform this reset if you wish to repurpose the AirPort Base Station or Time Capsule and want to remove all personal profiles and settings first. This reset resets the device to its state when you first purchased it. Data stored on internal or external hard drives connected to the device will not be erased. If you choose, you may manually erase the hard drive using AirPort Utility.

  • Airport time capsule losing network connection

    Running a time capsule with airport utility v. 6.3.2 and it is losing wi-fi and ethernet connection daily. I have had the unit for three years or so, and while it used to happen once or twice a year, its happening daily now. Unplugging/replugging gets it going every time. I have three  Macs and 5 iphones connected.

    It may be possible that your Time Capsule is failing. However, before considering replacing it, I would suggest that you contact your ISP and have them run a "line check" between their service and the Internet modem. Even if this check proves good have them replace the modem, especially if it is more than two years old.
    If after all this, you still have the issue with the Time Capsule, I would recommend that you take it to your local Apple Store to have them take a look.

  • IMac keeps losing network connection

    My iMac keeps losing the connection to my AirPort very sporadically, but very often. I keep having to open Network Assistant, choose the AirPort and the network, and re-enter the password. I then get a message that my network connection appears to be working correctly, which it then is. This could happen several times in a few hours.
    I have tried creating a new network, but it still happens. We have 6 other devices on this network and do not have a problem with those devices.
    Any advice?

    in the end, i decided to hardwire (using ethernet cables) most of my devices to my router (time capsule) in order to avoid interference alltogether.
    also, there could be closed (hidden) networks around that only KisMac would be able to pick up.
    lastly, as the read about *wireless interference* revealed, there are other sources that could interfere with your network performance: microwave ovens, cordless phones - heck, even enabling bluetooth on your very own Mac could be a source.
    as an alternative to running ethernet cables throughout your place, you could consider *powerline adapters* _*such as these*_.

  • Randomly losing network connection over wireless

    Shortly after installing the 10.4.5 software update, my G4 iBook with built-in Airport Extreme card has been losing connection with increasing frequency. Built-in Ethernet use is unaffected. I'm calling this problem thrash-and-drop.
    1. When it's losing signal, processor activity goes through the roof. I had Activity Monitor running during a thrash-and-drop. kernel_task CPU consumption goes from under 1% before the event, to over 80% during the thrashing, and back under 1% after the thrashing stops. The activity is so bad the cursor can't be controlled: using the track pad sends the pointer all over the screen or nowhere at all.
    2. This has been observed to occur with two different wireless base stations: A Linksys WRT54G and an older SMC 802.11b router. Either router is within 10 feet of the computer. Only one is running at a time. There are no other base stations in range.
    3. Another iBook G4 (OS 10.3, Airport Extreme card (not built-in)), sitting next to it, shows no change and its wireless behavior is unaffected.
    Initially, this seemed more likely to happen when Safari was loading Flash-heavy pages. And after thrashing and dropping a connection, it was able to reconnect after either a reboot or a five minute sleep. Currently, it can't connect to a base station for more than a minute. Most recently, it thrashed and dropped while I was selecting the base station to use. This is true regardless of the application running. In fact, it will thrash-and-drop when there are no user applications running at all, after a fresh reboot.
    I've tried the following things to address the problem. None have affected the thrash-and-drop problem. Admittedly, most of this is random:
    1. Back up and delete network preferences in /Library/Preferences/SystemConfiguration
    2. Turn off IPv6 in System Preferences/Network
    3. Back up and delete network preferences in ~/Library/Preferences (com.apple.NetInfoManager.plist and com.apple.NetworkUtility.plist)
    Has anybody else seen this problem? I want to blame it on the 10.4.5 upgrade but I haven't seen anybody else complaining about 10.4.5 doing this to them. If there's something I can do to fix this in a software setting, I'd much prefer that to yet another roadtrip to the Apple store.
    1.33 GHz G4 iBook   Mac OS X (10.4.5)  

    Hi!
    I have the same problem of randomly losing network connection over wireless, though mine is hardly related to surfing.
    I have an external storage drive in which I use for backup of my stuff, and I access the drive via my modem, using the airport. Of late, I noticed that when copying files from my iBook to the external drive, the connection would suddenly drop before the transfer is completed. This began to occur with increasing frequency, particularly when transferring large files.
    I have since abandoned wireless connection, and reverted to my trusty cable. Still, I admit that I'm really curious about the cause of the apparent lack of reliability with my wireless connection. Has it something to do with the airport?

  • HP Officejet Pro 8600 Plus losing wireless connectivity, cannot scan to computer

    In our office, we have roughly 4 computers using the HP Officeject Pro 8600 Plus, all of which are connected wirelessly. The printer was previously connected to the internet wirelessly with no problems. A couple of days ago however our computers started randomly disconnecting. The printing function would work for a bit, then disconnect. I found the only solution to this problem was to hit the button on our wireless router that resends the wireless signal out for connectivity. 
    We hardwired the printer with an ethernet cable and I myself didn't see any further problems regarding connectivity but a couple of the other computers had spotty connections.  Again, each time this can be remedied by hitting the button on the wireless router.
    Today  however we had an additional problem, after trying to scan a document through the automatic document feeder, the printer said it was jammed (although it wasnt). When we went to rescan, the scan to computer function was no longer working. I can scan by hitting the scan button on my HP Printer Assitant interface, and I can also scan to email, but cannot scan to computer.
    I have gone through several forums and haven't been able to find a solution. I personally use Windows 8, but other people in our office are using older versions of Windows. We've tried unplugging, restarting, hardwiring, resetting wireless settings, uninstalling, etc. etc. Before a few days ago the pritner was working fine for a number of months.
    If anyone has any ideas they would be greatly appreciated.

    Hi rtaw,
    Welcome to the HP Forums!
    I understand that you cannot scan to computer, and that you are losing wireless connectivity, with your HP Officejet pro 8600 Plus. I am happy to help you with this issue!
    Please take a look through this wireless guide. Printer Does Not Maintain Wireless Connection.
    For the scanning, please see this guide. A 'Connection Error' or 'No Computer Detected' Error Message Displays during Scanning.

  • AirPort Extreme loses ethernet connection

    I am running about 20 or so base stations in my school and every once in a while, a couple of the stations loose their ethernet connection. They are still broadcasting wirelessly, but they disconnect from the network. The stations are running fw5.6 and my clients are running 10.4.2 or WinXP SP2. The only way to fix the problem is to power cycle the base station. I also have the older graphite stations which work fine, which leads me to think that this is not a network issue.
    Any suggestions?

    I also lose ethernet connection. Sometimes once a day, other times 10 times per day. The other day I was so frustrated about losing my connection that I just walked away from it, without cycling power. When I came back (about 30 minutes later) from my cooling-off period, I found that the connection was back. So, with my AirPort Extreme, cycling power is not the only solution. It's not an acceptable solution though.
    I was wondering what you mean by your statement, "They are still broadcasting wirelessly, but they disconnect from the network." I'm relatively new to this stuff and this baffled me, which isn't hard to do.

  • Losing Internet Connections

    I switched from a Linksys wired router to the Airport Extreme wireless and did not experience any problems until recently. For the past couple of weeks I occasionally lose connection to the internet. The 4 lights on my cable modem that are suppose to stay lit sometimes flashes. Computers that are connected to the AE includes an iMAC running Snow Leopard, a Windows Vista machine, and 2 XP machines (through a Linkysy hub). The problem happens regardless of which machine I use (ethernet cable). When I called my cable company they claim everything is fine on their end and suggested I get a new modem.
    Before spending $75.00 for a new modem, which might not fix the problem, I decided to re-boot the cable modem and attach it my original Linksys router and hub, and it seems to be working fine. I've been using the original configuration for about an hour without losing the connection (i.e., all of the lights on the modem that are suppose to be on are on).
    Are there settings within AE that I need to change to address this issue?

    I've been having the same problem ever since I updated my software. I only have access to dial-up which makes downloading anything a pain in the ##%! In the past I have been patient, but now I get a message indicating that I have to chose to stay connected. Can't say how often it occurs, but it is at least less than an hour. I cannot sit at my computer while a file, that is going to take 4 hours is downloading, however if I don't I am disconnected and would have to start the download all over again. I have looked at all possible preferences to see if there is somewhere to resolve the problem, but to no avail. There has to be a way to get rid of this annoyance. Please help!

  • Time capsule keeps dropping ethernet connection to BT Voyager every minute

    I have just bought a 1TB TC to get the benefit of better wireless and the backup facility all in one. Previously I used a BT Voyager 2110 as ADSL modem and wireless router. I have set up the TC to connect from the WAN port to the LAN port on the BT router, put TC in bridge mode, and disabled wireless on the BT voyager. This means the BT Voyager does all the DCHP config and PPPoA, transmits this to the TC via ethernet and then TC broadcasts this on wireless. So far so good.
    The TC works with this ok, but for whatever reason keeps losing the ethernet connection every minute or so. Literally almost flickering from amber light ('ethernet cable unplugged' for about 1-2 seconds) then back to green light sometimes several times a minute. This means I get no continuous or stable connection, e.g. for downloading/gaming online. The same happens if the BT router is in bridge mode and the TC configures the PPPoA itself - it has to 'renegotiate' every minute or so, which is very frustrating.
    The ethernet cable is fine (I have tried two different cables), and each works with no problem if iMac is connected to TC (no internet though obviously), or if iMac is connected via LAN to the router for direct internet access - the network settings in system preferences shows no similar frequent loss of connection. The problem only seems to arise as between BT router and TC via ethernet. I have done resets of both the TC and the router, both are on the latest firmware updates as well so I am now at a loss. If anyone can help it would be really appreciated! Thanks.

    Hi there, thanks for your quick reply.
    Well I'm not actually trying to get the TC to do that function, merely to wirelessly broadcast what has been negotiated by the BT Router. I.e. the router is not a bridge letting the TC do the work, but rather the router has all the settings and then this is just fed down the ethernet, just like it would be to a computer.
    Connection settings have always been 'connect using' ethernet, and 'connection sharing' is off (bridge mode).
    The thing is that this config clearly does work as I can get internet access, but I can't work out why the ethernet connection is dropped so frequently (and at all) which means I have no stable connection.
    I have tried changing the router to PPPoE, which still gives me internet access but does not resolve the problem of the ethernet connection being dropped.

  • Hyper-V VM is losing external connection to Internet

    Issue:
    The VM's is losing network connectivity to the external network over the virtual switch when creating a third or fourth VM. Sometimes even local connectivity is missing, but not always.
    Scenario:
    HP ProLiant ML350p Gen8
    Windows Server 2012 R2 Standard with Hyper-V
    1 NIC for management, 1 NIC for VM's (HP Ethernet 1G 4-port 331i adapter, driver version 16.6.0.4.)
    LAB environment on separate subnet for 'proof or concept' with no user load - yet!
    Things I've tried:
    Update NIC to the latest available official driver on HPs webpage. No change. 
    Alternating settings for 'Virtual Machines Queue' in NIC driver settings. No change
    Replaced physical firewall. No change.
    Firmware update using HP intelligent Provisioning (sufficient?). No change.
    Replaced physical switch. VM can now connect to external network (!?)
    Workaround:
    I've found out that changing physical switch will restore connectivity. However, loss of connectivity will occur again after creating another VM - until the switch is replaced once again.
    I alternate between two switches; Dell PowerConnection 2816 and D-Link DGS-1008G. I know the D-link is a consumer switch (HP enterprise switches awaiting, but doubt it will matter) but it should work for now.
    Question:
    I'm not completely comfortable with putting this hypervisor in production with this irrational behavior and my question is if anybody else has encountered similar problems and if so how did you resolve it permanently?

    Hi Essen,
    >>The VM's is losing network connectivity to the external network over the virtual switch when creating a third or fourth VM.
    Sometimes even local connectivity is missing, but not always.
    According to the description , the first thing I want to do is to check if there is "MAC conflict"  .
    "Local connectivity" means "management NIC " ?
    Also I suggest you to test  whether or not these VMs connecting to same external virtual switch can access each other when the issue arises .
    Any further information please let us know .
    Best Regards,

  • I keep losing my connection from iMac to keyboard and mouse any help please

    I keep losing connection between imac and my mouse and key board.I then have to power off and reboot to get connection can anyone help please!!!!

    Hi
    Update date for anyone who ha suffered with the problem of losing connection to an ext HDD.
    For me, the solution appears to have been achieved by making use of my old 802.11 b&g Airport Extreme base station and my new 802.11 n Airport Extreme Base Station.
    My network is now setup as follows:-
    Airport 802.11 n - 5GHz
    Macbook Black
    Apple TV
    Time Capsule
    Airport Express Base Station
    Airport 802.11 b&g - 2.4GHz
    Playstation 3
    Xbox 360 Elite
    Nintendo Wii
    iPhones
    iPod Touch
    Canon Wi-fi Printer
    iMac G5
    Sony VAIO TX2P
    I connect my ADSL line to both AEBS by ethernet, changed the settings and this has dramatically improved my connection reliability and speed when streaming movies and/or music.
    Through trial & error, I have also discovered that the other problems that I have are connected to situations when restart my Macbook after a shut down or restart and my iPhone is connected. This causes iTunes to start up but due to the restart, the ext HDD is not ready and therefore, ITunes opens its local library - I now just try to remember to use the Option key to choose the library. Finally, if the laptop just runs out of juice, the ext HDD doesn't have the chance to have a friendly handshake before losing its connection. When I restart, the connection does to the HDD fails and I have to restart AEBS
    I hope that helps anyone with similar problems or who wants to make the most of their fast 802.11n equipment by making is use of that kit that was maybe considered redundant - by creating a dual frequency network that maximizes speeds on 802.11 n whilst allowing use of the legacy 802.11 b&g devices.

  • PCs losing network connection

    We often have one of our ethernet-connected PCs lose its network connection.  (not just the internet, the entire LAN connection). To get it back we either reset the Homehub 3 or simply swap the cables between ports on the hub.  It isn't always the same PC that loses the connection, so pretty sure the problem isn't at the PC end.
    I've spoken to BT in India and they sent a replacement Homehub 3, but the issue persists.  Both Homehubs are Type A.  The person I spoke with insisted they no longer make the Type B hub (which I wanted for its newer firmware).
    Although we do have the workarounds above, this issue is annoying so I'd like to find a solution.

    Hi foxycat,
    Do you get any error messages on the computer when it loses connection? I presume the error messages are the same on each computer? I'm also presuming each computer is connected to the Homehub using a different ethernet cable so this would rule out the cable being at fault. Is there one computer that doesn't lose connection at all, or does the issue occur when you switch on a certain device?
