Z1c Losing Network Connection for no Apparent Reason

Hi there, recently I noticed that after longer calls (ca 15+ minutes) my Z1c loses network connection ("No Signal" notification & empty triangle icon instead of signal bars) right after the call has been ended. I tried to turn on and off the airplane mode or to manually select the proper cellular network but these did not bring the signal back. The only thing that helps is restarting the phone (then I get full-strength signal). Just to be clear, I am not referring to a loss of mobile data connection as experienced by some users. What I see is a total loss of mobile network signal. In other words, when this occurs my phone is unreachable (people are not able to call or text me). In the Settings I have "WCDMA (preferred)/GSM". Changing this to "GSM only" is not an option for me because the 2G signal is quite weak and spotty in my area. Using "LTE (preferred)/..." is not an option either due to the lack of LTE coverage. (What can I say -- rural area... :/ ) Additionally, I have enabled the Stamina mode but I doubt this can be the culprit because the problem appeared also when I turned Stamina mode off for a day or so. I should also mention that I use A5.0 Lollipop; however, the problem started appearing only a couple of days ago (I never noticed any such issue with A4.4). Any help would be much appreciated. nvx

I suggest that you try to repair the phone software using PC Companion..
Before repairing your device you may want to backup your information first. Check out this topic for more information on how to.
How to backup?
If the issue should still remain I think that this needs to be examined and fixed at a repair center. For more information about how to submit your phone for repair and where, contact your local support team.

DHCP Failover, one DHCP Server Partners Supnet is deactivated, Clients losing network connectivity for 3 sec. after renewing they IP Adress

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?
Rgds

Hi 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.

Keep Losing Connection For No Apparent Reason

Have had BT Infinity for about 18 months or so now. Every now again, I get spells of it (the hub and the router) crashing out for seemingly no reason. Reconnects, only to disconnect again. Was so bad yesterday, it made PC unusable. Unplugged everything overnight last night, as lost my rag with it, plug it all back in again this morning. Worked fine until this afternoon, where it started doing the same again, all be it not quite as often as yesterday. I had the router changed out by Kelly Comms in Dec, but never had a problem with the old one, so was reluctant to change it, now I can see why!!
Any ideas, before I launch it up the garden?
Cheers
Solved!

A HH3 from BT, if you report this, could well resolve this.

Why am I losing disc space for no apparent reason?

The past few days, I have been losing disc space and haven't been adding anything.
I was at about 10 GB free, and suddenly my computer was telling me that I had 0. I freed up 2 more GB, and a few minutes later it was down to 371 MB, then 100 MB, then 0 (within the span about 15 minutes). I repeated this process, and about the same thing happened.
I've deleted about half of my iPhoto library, a large portion of iTunes, deleted Safari caches, and most documents. I even did scans with Grand Perspective, and it only shows about 40 GB taken up. I should have at least 34 GB open, and yet somehow that is not the case.
Even in the past hour, I deleted 500 songs, and my space has gone down. HELP ME!

First thing I suggest is be sure you emptied your trash after all the deleting.
I use WhatSize to check space on my drive.
Disk Inventory X is also good for this.
The X Lab: Freeing space on your Mac OS X startup disk has some good information on what to look for when cleaning your drive.

hi

Since about 2 weeks ago for no apparent reason, the internet on my iPad suddenly stopped working (when I open Safari, it says: "Safari cannot open the page because it is not connected to the Internet"), even though the Wifi icon in the top left corner still shows full signal. However, I noticed when I went into Wifi settings (Settings>Wifi) that there is no checkmark next to my network name (only the spinning circle icon, as if it's trying to process something). This only happens at home (I can browse the internet while connected to Wifi at university). My other Apple devices (MacBook Pro and iPhone 4S) work perfectly fine at home.
I've tried resetting my router, restarting my iPad, resetting Network Settings on my iPad, and tried following Hynes' instructions on this thread:https://discussions.apple.com/thread/2453187?start=15&tstart=0, but nothing has worked so far (although I have to admit that I found the instructions on that thread somewhat confusing, so there is a chance that I accidentally did not follow them properly).
Could someone please help? It'd be VERY much appreciated.

Try a soft reset by pressing down the home and sleep buttons simultaneousely until the Apple logo appears, then release the buttons. This is a safe proceedure, so you won't lose any stored data.

Hi,
For no apparent reason my phone stopped working...so I did a reset and got the message 'Restore Needed'. I connected to iTunes and got this message: 'iTunes could not connect to the iPhone because it is locked with a passcode. You must enter your passcode on your iPhone before it can be used with iTunes'.
The problem is, I can't enter my passcode because I'm not given that option on the iPhone. All I seem to be able to do is make an emergency call.
It's been working fine otherwise. Any suggestions?
This is the SECOND replacement iPhone I've had this week and I'm getting a bit fed up.
Thanks in advance for any help,

Are you referring to the 4 digit passcode needed to enter the phone and use it's features?
If so reboot your iPhone and enter the passcode to get it operational. Launch Image Capture on the Mac and connect the iPhone. Now you should be able to download the video files to wherever you want on your hard drive.

AP Express status light flashing amber for no apparent reason, network works fine

AP Express status light flashing amber for no apparent reason, network works fine, any ideas?

It flashes amber when there is some kind of conflict. If the internet is working but the amber light bothers you, airport utility ahould tell you why your airport is reporting a problem.
If airport utility thinks your airport is normal and the amber light bothers you, do a hard reset on the 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?
1.33 GHz iBook G4 Mac OS X (10.4.5) New to Mac, just switched from Windows 4 months ago.

Losing network connection in Lion.

I have noticed that in the past couple of days my network connection seems to go down for no apparent reason. I have to reboot iMac to get network connecitivity. I have my iMac hard wired to Linksys router. My network is not down since my iphone can connect wirelessly as well as my Macbook. I was wondering if there was a way to troubleshoot the issue. Would there be a log of any kind that I could look at in order to see what might be the culprit? What steps should I be taking to troubleshoot issue?
Thanks and I look forward to your reply.

I am experiencing the same issue on my 27' iMac (2011). Connections to shares get dropped often. I can reconnect sometimes, but others I have to restart AirPort. This is a major issue that is affecting my productivity.
Lion is not the OS I would have come to expect from Apple...far too many bugs. And to add insult to injury, Apple is silent and no patches are forthcoming?!
I guess their organization are too tied up patent trolling Android phone manufacturers and Google to insure quality gets out the door.
(Disclosure: I own 6 apple devices & 0 Android.)

Ethernet suddenly stopped working for no apparent reason

My late 2011 MBP is usually functioning as a desktop with external display and keyboard/trackpad, so I have it connected via ethernet when it's on the desk. However, my connection suddenly stopped working for no apparent reason.......... BUT clearly not a router problem as there's no problem with the wifi connection. System Preferences > Network > Ethernet is telling me:
Status: Connected. Ethernet has a self-assigned IP address and will not be able to connect to the internet.
Dunno how this happened, as to my knowledge I didn't actually do anything to cause this problem, just randomly stopped working. Any solutions much appreciated, thanks :-)

Macbook pro 13 inch mid 2010 crashing for no apparent reason

Hi there guys,
My Macbook Pro for the last few months keeps crashing for no apparant reason. I say this because it does not seem to matter what program I am running, how many programs I am running, or indeed have anything to do with my software. Im now sure of this because I took it to the genius bar today and they gave me a system format/reset and the problem is still there.
They also ran diagnostics on the hardware and everything seemed to be ok...
Has anyone else had this problem? I'll paste my report after my latest crash below incase anyone can make heads or tails of it!
Thanks everyone!

That panic was not caused by third-party software. If the problem is recurrent, the possibilities are:
A stale or corrupt kernel cache
A damaged OS X installation
A fault in a peripheral device, if any
Corrupt non-volatile memory (NVRAM)
An internal hardware fault (including incompatible memory)
An obscure bug in OS X
You may already have ruled out some of these.
Rule out #1 by starting up in safe mode and then restarting as usual. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Post for further instructions.
You can rule out #2 and #3 by reinstalling the OS and testing with non-essential peripherals disconnected and aftermarket expansion cards removed, if applicable. Sometimes a clean reinstallation may solve a problem that isn't solved by reinstalling in place.
Corrupt NVRAM, which rarely causes panics, can be ruled out by resetting it.
If your model has user-replaceable memory, and you've upgraded the memory modules, reinstall the original memory and see whether there's any improvement. Be careful not to touch the gold contacts. Clean them with a mild solvent such as rubbing alcohol. Aftermarket memory must exactly match the technical specifications of the machine.
Apple Diagnostics or the Apple Hardware Test, though generally unreliable, will sometimes detect a fault. A negative test can't be depended on. Run the extended version of the test, if applicable.
In the category of obscure bugs, reports suggest that FileVault may trigger kernel traps under some unknown conditions. Most, though not all, of these reports seem to involve starting up from an aftermarket SSD. If those conditions apply to you, try deactivating FileVault.
Even if FileVault is not active, an aftermarket SSD may be the cause of kernel panics. Check the manufacturer's website for a firmware update.
Connecting more than one display is another reported trigger for OS X bugs.
If the system is not fully up to date, running Software Update might get you a bug fix.
In rare cases, a malformed network packet from a defective router or other network device can cause panics. Such packets could also be sent deliberately by a skillful attacker. This possibility is something to consider if you run a public server that might be the target of such an attack.
Otherwise, make a "Genius" appointment at an Apple Store, or go to another authorized service provider to have the machine tested. You may have to leave it there for several days. There isn't much point in doing this unless you can reproduce the panic, or if you can't, it happens often enough that it's likely to be repeated at the store. Otherwise you may be told that nothing is wrong.
Print the first page of the panic report and bring it with you.

All of a sudden, for no apparent reason, it takes up to 5 minutes for the prompt for my password to come come on screen?

When I open Thunderbird it takes up to 5 minutes for the prompt to come up to enter my password. This has just started happening-for no apparent reason. I opened the program in 'safe mode' and it made no difference. Please advise.

Hello Matt,
I hope you had a nice holiday...
OK, so, opening in safe mode does not change behavior.
I'm on Mac (ver 10.9.5), Thunderbird 31.3.0 - up to date.
I'm using a POP server. If changing to IMAP will be beneficial please give instructions. I didn't find anything helpful on the Mozilla site for doing this.
recap:
It takes 2+ minutes for my password verification to come up.
It no longer automatically downloads new emails once I am able to enter password (I checked the account settings and it IS selected to do this).
It takes 1-2 minutes to send messages (no attachments).
I can't think of anything I may have done to cause this change in the way it works. Is there any other specific information you'd like?
Thanks,
Laura

what happens with the operating system safe mode?
Restart the operating system in '''[http://en.wikipedia.org/wiki/Safe_mode safe mode with Networking]'''. This loads only the very basics needed to start your computer while enabling an Internet connection. Click on your operating system for instructions on how to start in safe mode: [http://windows.microsoft.com/en-us/windows-8/windows-startup-settings-including-safe-mode Windows 8], [http://windows.microsoft.com/en-us/windows/start-computer-safe-mode#start-computer-safe-mode=windows-7 Windows 7], [http://windows.microsoft.com/en-us/windows/start-computer-safe-mode#start-computer-safe-mode=windows-vista Windows Vista], [http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/boot_failsafe.mspx?mfr=true" Windows XP], [http://support.apple.com/kb/ht1564 OSX]
; If safe mode for the operating system fixes the issue, there's other software in your computer that's causing problems. Possibilities include but not limited to: AV scanning, virus/malware, background downloads such as program updates.

Firefox 15.1 stops responding for no apparent reason!

As the title says, Firefox 15.1 stops responding for no apparent reason!
I just did a re-format of my system disk and I re-installed Vista 64-bit on it. I have obviously re-installed everything from Windows updates to chipset, graphics and sound drivers. I also pulled down the latest and greatest version of Firefox which at the time is 15.1. So installed that too.
Every now and then Firefox just stops responding for no apparent reason. It looks like it is processing the request (after clicking a link etc.) but it then it's just a silence... nothing happens!
It doesn't even say it can't load the page and Windows doesn't even say that it has stopped responding. Not even after I click like crazy on the Firefox interface like different buttons and tabs and on the web page... not even then does it say "not responding" in the title bar of the window, which is usually the case when you deal with programs that are not responding immediately (you get that dialog that asks you if you would like to close the program or search for solutions online). Just nothing!... it's only quite and does nothing....
At the same time, all other programs are working flawlessly, such as the Explorer (Windows Explorer), or even Internet Explorer. And Internet connection is not lost!
I have no add-ons or extensions installed whatsoever. I just installed Firefox! I haven't even had the time to install Java yet. All I have is Adobe Flash player. That's the only extra. Otherwise it's in its' original form, default settings, etc, etc, etc.
Why is it acting up like this?...
I'm surprised that there even is such a thing as Firefox 15. This one came at the end of August, correct?
I have been on Firefox 14.x something before I re-installed Vista. For a good reason so! This is why I hate the new update model of Firefox and I don't jump on the next train (version) unless it's safe and I'm having compatibility issues with the one I use at the moment. This is why my first step after installing Firefox always is to disable automatic updates! I hate it when the software vendors are pushing out their latest software versions forcefully.
Frankly, I think this new Firefox version of yours is crap. It's not properly tested and it doesn't belong in the official release channel. This is more like a nightly build or something. It probably has some memory leak, despite the promises made by Firefox engineers that it will not have memory leaks and that it would be the fastest version of Firefox ever. I don't really need a faster browsing, I need a stable browser for reliable browsing. The speed of this Firefox version is close to ZERO! When it's not responding at all...
I have been a fan of Firefox since 0.8. I will be probably ditching this latest version and going back to an older version like 13 or 14 that's more closer to the reality and not in this fantasy world of fastest, greatest, latest, version this, version that, latest features. I just want a browser that works man!... I'm getting tired of Firefox. I may even ditch it altogether in favor of.... I don't know.... Safari?... Chrome?.... I might even go back to Internet Explorer after like 12 years of absence.

please try to uninstall the adobe flash plugin from the windows control panel. afterwards manually delete any leftover files in ''C:\Windows\SysWOW64\Macromed\Flash'' and download & install the plugin again (uncheck the option to install the bundled security software): www.adobe.com/go/getflashplayer
