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?

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?

All in One Printer, losing network connection
I have an HP Photosmart, 5510. It's only about a year old but is now always losing the network connection. I have it set up properly (it has actually worked!) to the wireless router. Most times now when I need to print, it tells me the printer won't communicate with the computer. I have taken it off the network, put it back on, and it says it is all connected. I have printed out the network status page, all is okay, no problems found. Why then am I still unable to print? This is very frustrating.
I have it set up to my Macbook Pro and my iPad. It has previously worked on both devices, but I can't seem to get it back to working order now.
I have looked at the forum here and have seen many many people with the same problem, but most seem to be using a Windows operating system. Any ideas on what to do? I really need to print!!
This question was solved.
View Solution.I feel that perhaps either my post was in haste or in error since I did not see the above solution you provided when I posted this. I do not mind helping you out with router and network problems either way, but since you do not know the name of your router, it will be hard for me to assist with that. I will say, you can always contact your internet service provider and have them check for a firmware update if you have to reset the router that often. If you look on the back of the router you will see little numbers (specifically a model number).
Is that IP address that of the router or the printer?
Either way, I am very happy to hear you were able to get it working again. If you need any more assistance let me know which device has that IP address and at least a model number so I can look up your type of router and let you know if a firmware is available. I'm happy to help!
Don't forgot to say thanks by giving "Kudos" if I helped solve your problem.
When a solution is found please mark the post that solves your issue.

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?LB60 wrote:
What am I looking for in the window that pops up?
here's a (very crude) screen shot of an iStumbler scan on my MBP
my network is called pegasus. see that it broadcasts on channel 11 (2.4 GHz band) ? see also that there are six other networks broadcasting on the same channel ? now, ideally i would change my channel to broadcast on "5" or "6", but since there are so many networks around, even those would give me interference from other networks nearby.
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*_.

Losing network connection (phone, text, data)
For the past couple of weeks I have had problems losing my network connection affecting phone calls, text messages and data access. The problems seem to be occurring more frequently, and have not been able to identify a consistent pattern yet.
Phone: On 2-3 occasions recently, I have had calls dropped. I see that I have no [phone] network connection. In each case I've been in a location where I frequently make calls. Twice this was while on a major freeway in the SF Bay Area. In each case I do get a signal back, but it takes several minutes until I re-acquire a signal.
Text: On multiple occasions (3-4 in the past week), I have tried to send text messages from my office (in San Jose), where I have not had problems in the past. After waiting for several minutes to re-acquire a signal, I re-booted my phone and my text messages were sent as soon as the phone re-booted. Note: changing the phone to airplane mode and then off, did not resolve the problem.
Data: On multiple occasions (8-10 times in the past couple of weeks), I noticed that my phone shows "4G", but no arrows and I have no data access (i.e. no access via web browser, can't use any email apps, can't use any apps that use data access). Once I lose the data connection, it never re-acquires the network even after moving and/or waiting in excess of an hour. The only way to re-acquire data is to re-boot my phone.
This seem to have started 2-3 weeks ago, but definitely getting worse over the past week - very, very frustrating!
Using Samsung S4, running Android 4.4.2. I don't recall installing any new apps or new O/S versions in the past couple of weeks, though many updates auto-installed.I tried removing/replace the Sim card. Still have the problem.
I got really frustrated with this and after spending over an hour on the phone with technical support and then with Assurion, I got them to replace my phone, with a replacement S4. Spent another couple of hours getting my phone reconfigured, including having to spend another half an hour on the phone with technical support because the new phone wasn’t activating on the network. And, still have the same problem on two consecutive days where the phone hangs when I try to make a call at the end of the day. (Though I had been able to make a couple of calls during the day).
So:
· It fails in safe mode
· It fails if I set the network to LTE/CDMA rather than Global
· It fails after re-seating the Sim card
· It fails with a replacement device
What’s going on? How do I fix this? -
Hello,
currently we are using two W2K12R2 DHCP server configured in "load balance Mode". On DHCP1 the IP-scope with failover partnership to DHCP2 is deactivated. DHCP2 is working fine. Now we register that 50 percent of our clients (W2K8R2 application
server) losing the network connectivity for 3 sec. after rereleasing they IP-Address. On DHCP2 servers eventlog we receive a lot of
BINDING ACK reject events 20291 and 20292 for these IP addresses entries.
These 3 sec. of loosing they Network connectivity is our big Problem because the Client application (W2K8R2 application server) cannot handle these timeout. It looks like a
DISCOVER-OFFER-REQUEST-NAK cycle that are described here:
http://blogs.technet.com/b/teamdhcp/archive/2014/02/26/dhcp-failover-patch-to-address-a-reservation-issue-and-another-issue-related-to-failover-partner-not-accepting-state-transition-from-bad-address-gt-active-has-been-released.aspx#pi47623=2
there is a solution to prevent the 3 sec network failure?
RgdsHi Steffen,
Have you applied KB2919355 in the server?
If issue persists, please check the detailed information about the event. It will tell us why does the server send the NAK.
Best Regards.

Losing network connection and NIC acts weird from warm/hot weather/temperatures?
Hello.
Is there a known issue on MSI P43 NEO3-F (MSI-7514) motherboards' onboard RealTek RTL8168C (P)/8111C(P) PCI-E Gigabit Ethernet NIC network disconnecting and acting weird during warm/hot weather?
I noticed lately and back on 1/11/2009 night when weather got warm/hot (e.g., my room can get over 85F degrees, but lately it has been 80F degrees), my network would lose its connection. See http://img9.imageshack.us/img9/5580/screenshots.gif for a few SpeedFan's sensor readings when the incidents occurred. I have never seen this happen when the weather is cooler (60-70F degrees in my room).
I also think this only happens if I am using the PC lightly (nothing intensive) like watching fullscreen videos (video overlay), surfing the Web, etc. I don't see any errors or evidences that it happens when idled (e.g., asleep or out). Uptime doesn't seem to matter since I have seen days to 3.5 hours.
I tried upgrading network driver twice (e.g., Realtek_XP_5714_0219 from
http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=13&PFid=5&Level=5&Conn=4&DownTypeID=3&GetDown=false ...), disabling Kerio Personal Firewall v2.1.5 (XP's disabled already), releasing and renewing IP address (works, but still no network -- can't even ping my router!), unplugging and replugging the cat5 cable (do see the network port lights on), touching the network jack and hardware inside and outside of the case (not hot), trying another cat5 cable and a network port on a switch instead router's), changing from "Minimal Power Management" to full power (no underclocking/slowing down when idled), etc.
During the disconnections, I tried:

I also noticed the disconnections usually start with red X icon in my taskbar with its bubble and then later the long disconnection even though no red X (1 GB and connected). If I were to disconnect the cat5 cable from NIC, then it wouldn't even detect it is missing the cable!
The only way to fix this was to reboot (best way and last longer) OR disable network connection and re-enable it (Windows XP's Network Connections) or the NIC itself (Device Manager), but that doesn't always last long (maybe a minute). Example of my pings right after disabling and re-enabling NIC:

Force your NIC to run at 100Mbps full duplex and see how it goes.
Check your router / switch ports as well as cables.
I will try 100 Mbps if it happens again. So far, it hasn't occurred after installing the driver supplied by MSI's Web site and not RealTek's Web site. The room temperatures even got warmer like 83F degrees.
As for router and switch, what am I checking for? Other computers didn't have any problems. As for cat5 cables, I already tried another one like I said in my original post. -
ATV keeps disconnecting and losing network connection
I konw this has been posted on seval discussion boards, but the answers are all over the place. I have been watching Netflix over the last several weeks and noticed that almost routinely my ATV will stop playing and go back to the home screen. Sometimes I am able to resume where I left off but more often it loses my network connection. I have to unplug ATV or go through the menue and reset.
I have not had this problem until recently. I have done all of the disconnecting, checking cables, restarting router, etc. Nothing seems to work. I even cancelled my Netflix subscription because I thought it was their issue. However, I have learned that it must be the ATV itself. I love my ATV, but I can't seem to figute out why this is happening. I don't have any other issues with WiFi in my house or with any other devices.
Any ideas if this is a software update issue? I did read that people were having issues after the latest software update.We've had our ATV for about a year and it's always worked perfectly. But every day for the last five days it has needed to be reset each day. Doesn't matter if we are trying Netflix, YouTube, or Podcasts it will say "can't connect to server, try later." So we will either unplug it and plug it back in or select reset from the general menu then everything works again. Can't figure out why it's doing this. All software is up-to-date.

IPhoto 11 keeps losing network connection
Ever since OSX Lion and iPhoto 11, one annoyance is, when you first load iPhoto, everything is 100%. Perfect. Then you go on and work with something else and when you return to that iPhoto 11 space, click share, and all the network connections are grayed out. You cannot upload or eamil photos to anybody. The only way to reconnect is to quit iPhoto and start again. This is non-productive behavior. This is ridiculous. This defeats the whole purpose of having iPhoto.
Did I do something wrong? Did I overlook some kind of settings?
Is there anyone else out there who experience the same thing?
Is there any Apple staff or inside people here who knows what is the fix?
Please help.No Apple developers here. Only users like yourself. Sounds like a damaged library. Try this: launch iPhoto with the Option key held down and create a new, test library. Import some photos and check to see if the same problem persists.
If it doesn't then try the following to fix your primary library: Apply the two fixes below in order as needed:
Fix #1
Launch iPhoto with the Command+Option keys held down and rebuild the library.
Since only one option can be run at a time start with Option #3, followed by #4 and then #1 as needed.
Fix #2
Using iPhoto Library Manager to Rebuild Your iPhoto Library
1 - download iPhoto Library Manager and launch.
2 - click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
3 - Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option.
4 - In the next window name the new library and select the location you want it to be placed.
5 - Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments. However, books, calendars, cards and slideshows will be lost. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.

IMac is losing network connection
Hi all, since the latest Update to ML 10.8.4, my iMac loses the connection to my NAS server (Synology Diskstation DS212+) from time to time, which results in a freezing of the Finder. Due to that, the whole system "hangs" until the "Network connection lost" info box is shown..
I can also manually disconnect from the NAS (via WebInterface of DS212), then most of the time I can access the Mac again.
Did anyone encounter similar problems? I think I can exlude the NAS server as source of the failure, because I have two more iMacs (without the newest update) that don't show that problem.
All advice is appreciated! Any ideas, hints where to look?
Best regards
OliverAny ideas, hints where to look?
Synology tech support, or its user forums. All third-party NAS devices use the wretched "netatalk" impletmentation of AFP, which is completely untrustworthy. -
Creative Cloud losing network connection/deleting files
My team has been using Creative Cloud since June 2014. We work off of macs running OS Mavericks and use an internal server. For months now we have experienced errors mostly in InDesign where we lose our network connection, InDesign crashes, and our files either delete or revert back to the original version despite multiple saves. We have had network and server specialists in and have ruled out any internal connection issues. Could this be a Creative Cloud issue and are there any recommended fixes?

Wired PC losing network connection to AE
I have an Airport Extreme, a Power Book (wireless), and a destop top PC.
I hook up the AE to my ethernet jack, and the PB connects just fine.
I hook up my PC through wired network connection on the AE, and I get a "network cable unplugged" error on the PC. All the while my PB is doing just fine.
I then bypass the AE, and plug the PC directly into the wall, and my PC connects just fine, so it doesn't seem to be a problem with my NIC, driver issue, or bad cable.
The other funny thing is this is a new problem. All three components WERE working just fine.
Any thoughts as to what I'm doing wrong?Check your settings against this guide:

Several Macs losing network connection
We recently upgraded 20 Mac computers ranging from first generation G4s to dual 2.7GHz G5s (no Intel procs). Of these Macs, five constantly lose their network connection - no Internet, Intranet, network drives, printing, etc. This happens several times a day. Out of the five computers having this issue, three are G4 towers, one is a G4 cube and one is a G5. All the other Macs are fine after the upgrade. The 20 Macs are on two different subnets within the building and we have Macs on both subnets experiencing the problem. These machines run similar applications, were all upgraded in the same way around the same time, and are running 10.4.5. I am upgrading a couple of the machines to 10.4.6 to see if that helps, but I am not holding my breath. The computers a plugged into Ethernet drops. Four out of the five experiencing problems use DHCP and one has a static IP. I saw other people that were experiencing this issue on home and work machines, but no solutions. Please help. My users are getting tired of rebooting several times a day. THANK YOU!
G5 Mac OS X (10.4.6)I'm having the same problem with my Mac Pro and my home Airport network. Other machines (MacBook and iMac) see the network fine, but the Pro keeps dropping out and the only cure is to restart.

We have 2 computers and Apple TV that will be connected to internet while my iPod loses its connection. It seems to happen after it goes to sleep for a while like a half hour or so, haven't actually timed how long. But I won't get iMessage notifications. As long as I am actively checking my gmail or texting or searching internet I don't lose connection, just after it sits for awhile.
New(2 months old), 32GB (still have 15GB available), iOS 7.1.2, I only have one wifi network connection setup on it and have "ask to join networks" set to offHow do I make IOS 6 keep wifi on when iPod is sleeping?
