Lost connection (short)

I have a WRT54G router. 3 desktop PCs connected with network adapters (WUSB54G) and a laptop with an unknown network card.
This configuration has worked flawlessly for 2 years.
All of a sudden the remote computers are experiencing BRIEF periods of lack of connection. This is highly problematic when users are working on documents on the network or doing web-based data-entry or other activities where SOLID 100% up time network is essential.
What might be causing the loss of signal/connection to the network? How can it be fixed?
Thanks.

Did you tried upgrading the firmware in two years of time ... because if the software is older than the disconnectino will happen ... so first check the updated firmware for the router ...
After upgrade .... reset & reconfigure the router ...
See if it works ....

Why has my ipad lost connectivity to the AT&T cellular data network after upgrading to iOS 8.1.2? My iPad is model #MD367LL/A, 32 GB WIFI + Cellular, about 2-1/2 years old.

Why has my ipad lost connectivity to the AT&T cellular data network after upgrading to iOS 8.1.2? My iPad is model #MD367LL/A, 32 GB WIFI + Cellular, about 2-1/2 years old. It;s been working perfectly up until now. I have no problem on my home WIFI, or through personal hotspot working through my iPhone 5.
I have worked with AT&T, replaced the SIM card with a new one, and done a backup/restore to factory settings, all with the same result that when I turn Cellular
Data on, with or without Enable LTE, it goes into "searching" mode, or reports "no service". My iPhone 5 works perfectly on iOS 8.1.2, on Cellular. I've browsed the blogs and have tried Apple's suggested fix, all to no result.
Oddly enough, every once in a while I do get connected to the network for a short ime (minutes), but it always returns to "searching".
I've filed a report with Apple, along with a request that they contact me, but no results yet.
Help? (and thank you).

Hello razmee209. Thank you for your response. I spent the better part of yesterday working with Apple Support. They tried their best, to include backing up photos to my HP laptop, backing up the iPad to iCloud, then resetting the iPad in total. Same problem. I restored from the cloud to recover my apps, same problem.
AT&T installed a new sim card - same problem. I spent time with AT&T Support yesterday, too. In both cases, (Apple and AT&T) the support techs who worked with me were extremely polite, courteous and helpful to the best of their abilities, but I think the problem lies deeper, and nobody at Apple is admitting they have a problem with iOS 8, that I'm aware of.
I didn't have this issue before I upgraded to iOS 8.1.2.
Everything else with the iPad works fine: WIFI, Personal Hotspot, email, all my apps, etc.
In browsing the web for this issue I see that many other folks have the same problem. I filed a report with Apple this morning, requesting that they contact me, but no word yet. I was going to go to iPhone 6, and had been considering the iPad Air 2, but I see reports of this problem with those units as well.
At this point I don't think I'll be spending any more money with Apple, at least not till this issue is resolved.
Thanks again for your response and suggestions.

Apple Wireless Keyboard lost connection when "command+space" is pressed

Hi, my apple wireless keyboard lost connection when command and space key was pressed. it does not lost connection when other keys combination was pressed. Are there any people has the same problem with me?
I am using Emacs all the time, the command and space key is the default short cut for Mark in Emacs. It is constantly used in my daily work. The wireless keyboard does not lost connection always, but it does lost connection sometimes. I have observed every time it lost connection, the command + space was pressed. Really strange. Any advice?
I am using Macbook Pro 13inch Late 2012, OSX 10.9.1, and Apple Wireless Keyboard

Got the keyboard working again, here how incase it can help anyone else:
I borrowed a USB keyboard to allow me to get past the pasword login.
First I rang disk utitlity to repair any permissions. I opended up the app 'Bluetooth Setup Assistant' selected 'Keyboard' then I turned the keyboard 'on' so the green light is flashing' and then hit continue. At this point the keyboard appears in the listing of found items, hitting continue I am then given a unique pairing code. Enter this on the keyboard and hit 'Return' after a few seconds, the pairing is complete and by wireless keyboard is back and working again!

Adobe cloud has lost connection with the server

Adobe cloud has lost connection with the server, can't get adobe cloud to work so I can re-install photoshop to fix a corrupted DLL file.

*Adding new items/removing orphans*
Try iTunes Folder Watch or iTunes Library Updater. Folder Watch is much faster on the adding files front, can be set to run in the background and includes a useful exclusion feature, however it’s slow at removing orphans. iTLU is better for this although doing it manually after looking at a list of proposed removals generated by Folder Watch is probably faster still. iTLU can also be set to update iTunes when you've used 3rd party tools to change tag info.
You may need to amend the list of file types these programs look for. My list includes:
.mp3 .mp4 .m4a .m4b .m4p .m4v .mov .wav .aif .mid .ipa .ipg .ite .itlp .m4r .pdf
Note the last 6 types may not be recognised as already being in the library so should either be omitted from the search or you can add (at least for Folder Watch) individual exclusions for files you know are already in your library.

"Lost Connection with AIM" repeatedly

Hi there,
I'm using a new Linksys WRT54GL router with the DD-WRT v23 firmware -- which is otherwise fabulous, by the way -- but since going with the router iChat has been pretty unreliable. I can't connect to my sister in England (I'm in Canada): we keep getting "insufficient bandwidth" errors (I'm on a very hi-speed cable internet connection, so I don't think it's me!). Moreover, AIM frequently kicks me off iChat with the message "Lost connection with AIM".
I've configured my router using instructions linked from this forum. I'm forwarding the following ports to my computer:
5060
5190
5220
5222
5678
16384
And while I can connect to other users okay (except my sister, it seems), staying connected it a real issue. Can anyone recommend a fix?
Thanks,
Aaron.

Hi Aaron,
This last port should be a group of 20 ports (16384-16403)
iChat needs 4 ports from this group to do 1-1 Audio or Video chats.
Many Linksys have UPnP. It is found in the Administration tab. If you have this you could use this. Disable the Port Forwarding if you do.
Also port Forwwarding points to one IP/computer. If this is the case for you and you still have the device doing DHCP there is a cance you computer's IP has changed if it goes to sleep or is shut down when the lease time runs out.
Check this on your computer and the Port Forwarding settings.

"Lost connection with AIM" error message

Hi all,
I've been a long-time iChat user — I've had very few problems, but now, at home, whenever I've been connected for about 10-15mins, iChat just disconnects with the simple iChat Connect Alert that the app has "Lost connection with AIM. The connection with the host was unexpectedly lost."
My Buddy List collapses to a "disconnected" header and I diappear from my Buddies' buddy lists. If I'm in the middle of a chat (video, audio or text), the chat continues uninterrupted, but I still disappear from people's lists as if I'd disconnected manually. Weird.
The net result is that I have to keep checking to see if I'm connected and then reconnecting all the time. A real pain in the proverbial.
It only happens at the house. My laptop doesn't disconnect if I'm at the office, for instance.
I have cable, coming in to Netgear 814v2 router; out to an 8-port gigabit switch, which then feeds my three main machines. All via ethernet cabling.
All machines have the same problem described above.
I've made the usual Quicktime setting changes.
I've listed the necessary ports in my Mac firewall settings (even though the firewall is turned off).
Each machine has a dedicated IP issued by the router (10.0.0.2 thru 10.0.0.5)
The router firmware is up to date.
What else is there?! I have no problems initiating or joining any sort of chat with my buddies around the world. I have excellent bandwidth. My internet and email are never interrupted 24/7.
Can someone help me? Pretty please?

Hi
Try this log on to AIM on port 443 rather than port 5190
Go to IChat > Preferences > Accounts.
Log out of AIM and then use the Server Settings tab
Set the port to 443.
Log back in again.

I can no longer log into my ichat linked to my gmail. right after opening up ichat, receive the following message: lost connection with jabber. the server has unexpectedly disconnected.

i can no longer log into my ichat linked to my gmail. right after opening up ichat, receive the following message: lost connection with jabber. the server has unexpectedly disconnected. how to troubleshoot? thanks.

Hi,
There can be many reasons why the Login is "up the creek".
Any break in the network at your end whilst logged in will cause an issue.
A sort of discrepancy between what iChat thinks the state should be and what the server thinks.
If they don't agree the server will refuse to accept.
A Crash at the server end which does not log you out properly will also do it.
Any file at any time can be come corrupted.
Luckily with the iChat .plists they are recreated if removed with an iChat Restart.
If it were AIM you can also get your Account Suspended and this will not log you in.
(It tends to happen from Chat rooms where people notify AIM about bad behaviour (as they see it) and you have to apply to get Un-suspended).
Most of the big IM services use multiple servers.
Sometimes these go out of Sync.
In the case of AIM this happens when they remove Old unused Screen Names from people's Buddy List prior to making them available for re-registration. I am not sure if this happens at Google.
You seem to be talking about an account that has worked at Work and having new computer at home.
As I mentioned the Priority thing you have not said that it has coincided with the new computer logging in (this will kick the work Computer out of Google whether you are logged in on the Web Mail page or in iChat)
IN addition to that iChat stays partially logged in for Off Line IMs
This is done in the background by a support app called iChatAgent
If your Computer is ON but ichat is not started people can still send you Messages.
Instead of saving these on the server until you login iChat will start up.
Depending if the home Mac is effecting the Work Login it may be holding sway over your Login.
Using your girlfriend's login may have booted her Off Line where she normally uses the name/login.
The AIM Side can be specifically set to allow Multiple Logins and therefore NOT allow them. If this happens you get a warning and messages to do something about it.
You do not get these in any Jabber or Google Login as the Priority setting is supposed to take care of it.
If the Login works at the Web Mail Login and on one computer then the .plist on the work computer is the most likely issue.
There is a small chance that a Corrupt Buddy Pic (Home Folder/Library/Caches/com.apple.iChat/Pictures) may be the cause.
Set this folder to icon view and also use the Finder's View Menu > Show View Options and select icon view.
This should show all pics as their icon.
Check that all display properly.
At this point I would try a COMBO version update install of the last Update you did over what you have.
This often corrects hard to trace things

Lost connection with server

For about two days now, the bbm application has refused to launch. It has been writing lost connection with server....can any one please help! It's really urgent

Hi and Welcome to the Community!
With a strong carrier network signal (e.g., not merely WiFi), I suggest the following steps, in order, even if they seem redundant to what you have already tried (step should result in a message coming to your BB...please wait for that before proceeding to the next step):
1) Register HRT
KB00510 How to register a BlackBerry smartphone with the wireless network
Please wait for one "registration" message to arrive
2) Reboot
Pre-BB10 Devices ONLY. With power ON, remove the back cover and pull out the battery. Wait about a minute then replace the battery and cover. Power up and wait patiently through the long reboot -- ~5 minutes.
BB10 Devices. Hold the top button down until the counter reaches zero. Wait for the device to be fully shut down (e.g., nothing at all displayed on the screen, no LED lights, etc.). Hold the top button until the red LED is lit. Wait through the full boot-up process. IF this fails, you can attempt the battery-pull method above, but it is normally NOT recommended unless nothing else works.
See if things have returned to good operation. Like all computing devices, BB's suffer from memory leaks and such...with a hard reboot being the best cure.
Hopefully that will get things going again for you! If not, then you should contact your mobile service provider for formal support.
Good luck!

NVIDIA OpenGL driver lost connection with the display driver

Alienware M14x Laptop
Windows 7-pre 64-bit
8gb ram
3gb Video: NVIDIA GeForce GT 555M
Intel i7 2760QM
AE CS4
AE keeps crashing. I get the following message while doing something as simple as scrubbing through the timeline, or changing opacity of a layer. in 1080p, I have a picture layer, a solid, some color corrections, and that's it. i just got this new computer and i have never had this problem on my old computer.
this message appears after AE crashes."The NVIDIA OpenGL driver lost connection with the display driver and is unable to continue. The application must close."
this message appears in the taskbar: "Display driver stopped responding and has recovered. Display driver NVIDIA Windows kernel Mode Driver, Version 267.21 stopped responding and has successfully recovered"
any ideas on how to stop AE from causing my display driver to stop working?
Thanks, Ramzi Rebeiz

For anyone picking up this thread (it's probably too late for rrebeiz40 by now!) I have come across a simple but apparently very effective tip that has solved the 'OpenGL driver lost connection' issue for many people using various NVIDIA with various Adobe progs (incidentally a lot of these seem to crop up on Dell machines, especially Notebooks).
(It fixed my issue with Premiere Pro CS4 - GeForce GT 555M on Win 7 Ultimate 64-bit, Dell XPSL702X).
It's posted on http://forum-archive.developer.nvidia.com/index.php?showtopic=5331&st=40 (look for the last post, No 50) as follows:
THIS FIX APPEARS TO WORK...found on an Adobe forum
"This issue led me to this fix: go to NVIDIA Control Panel --> Manage 3D Settings --> Global Settings, and switch "Power Management Mode" to "Prefer Maximum Performance" (the default "Adaptive" setting seemed to be the culprit). And that's it! The key here is changing the "Global" setting, as my individual programs were already set to "Prefer Maximum Performance." I can cause the error to reoccur by changing back to "Adaptive."
Otherwise lots more ideas on this site: http://www.instructables.com/id/How-to-Fix...Nvlddmkm-Error/
My PC has been running for 2 days now. I only put the top fix in for now. Feel happier I have more options if need be though.

Nokia Ovi Suite has lost connection with your devi...

5 months has passed and many hours on the phone to Nokia. The phone has been completely reset /reboot by Nokia time and time again and still the phone gets this message when trying to update software..."Nokia Ovi Suite has lost connection with your device"....We were optimistic that the software upgrade would solve the other problems we are having with all the Nokia phones at work. They are all E52's

Having the same issue currently with an E72 software version is 054.005.266.02 and Ovi Suite 3.1.1.80
Actually I had connection lost all the time with all previous versions of Ovi Suite too... it has never been reliable.
Using original Nokia USB cable, connected securely. Tried different PCs, different USB ports, same issue.
Just now I'm trying software update and it looses connection during the backup process all the time... very disappointing. Screenshot attached if anybody is interested.

E5: Ovi Suite has lost connection with your device...

I am trying to update the software on my E5 using OVI suite but I keep getting an error during the install phase (after backup). The following error and instructions are displayed in the OVI suite window but makes no difference when I follow these instructions (just end up back with the same error).
"Nokia Ovi Suite has lost connection with your device. Follow these steps to help reconnect your device:
1. Remove USB cable from your device.
2. Restart the device (turn off and on again).
3. Re-insert the USB cable.
4. Click 'Ok' below to continue updating."
Current E5 software version is 042.007.
I am trying to update to E5 software v. 043.115
Any ideas?

Yep having the same issue. Just got a replacement handset due to the random restarting issue, soon after setting up the new handset I get a message on phone saying software update is available. Both OVI suite and Nokia software updater say version 43.115 is available (about 200mb in size), I currently have the same version as you 42.007. It claims to do a lot of improvements to the handset. The update downloads fine but when it comes to installing I keep getting the same issue. Phone simply will not restart automatically and the update restarts then fails at the same point over and over. Had the same problem with my previous handset.
I spoke with my network provider to see if it was an issue with the handset needing firmware specific to them but they said no it is an issue with the firmware itself and has been happening to everyone since its release!!! They said I should not download it until Nokia has resolved the issues with it. But how do I know when that will happen as I cannot find anything put out by Nokia stating there is an issue or anywhere on web forums saying there is actually a problem.

Disk Utitlity has "Lost Connection" with Disk Management tool"

[ Edited by Apple Discussions Moderator; please start a new topic about your technical issue. ]
Running OSX10.3.8
I installed:
"iTunes" (6.0.2)
"iPod Updater 2005-11-17" ((null))
"iChat Update" (2.1)
Went to repair disk permissions
I get this error:
Disk Utitlity has "Lost Connection" with Disk Management tool" Please quit Disk Utility.
then it says quitting Disk Utility may render the disk useless. Stopping the scan just gives a "stopped by User" red text message in the DU screen.
Had to Quit. No other way out.
Now it will not repair "or" verify Disk permissions at all.
What to do?
Powermac G4 1.25ghz, OS9/OSX Mac OS X (10.3.8)

Getting the same results booting off of the install CD. I even ran fsck -y after a soft boot(command S). Note I also installed the iPod updater and iChat update.
I'm getting a crash log that has to do with DiskManagement
Path: /System/Library/PrivateFrameworks/DiskManagement.framework/Resources/DiskManage mentTool
I tossed the pref file for Disk utility and tried to locate a pref for the Disk Management but nada...
Is there a prefs file that needs to be tossed?
Anyone do a recent Onyx Maintainence cleaning?
Is there a way to do an iTunes Uninstal and reinstall a previous version?

'Disk Utility has lost connection with Disk Management Tool' w/ RAID 10 set

Using 4 internal drives, I have specified the following setup for each:
2 partitions, 1 'speed' of 5 GB and 1 'data' of whatever remains.
The 4 speed partitions stripe to a single RAID volume correctly.
The 4 data partitions are used to make a RAID 10 volume as follows:
The first 2 data partitions are mirrored to make a 'data-A'
The next 2 data partitions are mirrored to make a 'data-B'
These complete correctly.
Upon attempting to strip data-A and data-B in order to finish the RAID 10 setup, Disk Utility quits with the following message:
"Disk Utility has lost connection with the Disk Management Tool and cannot continue. Please quit and relaunch Disk Utility'.
A search here and on the nets reveals only that this message appeared in 10.3.x when attempting to repair disk permissions and had to do with a rogue iTunes support file. This is occurring on a blank system (no iTunes installed) so I don't think its the same cause.
Note that I was able to complete this setup under Tiger several times without issue, so it seems to be unique to Leopard. Does anyone know what is going on and hopefully suggest a workaround?

To answer my own issue and leave a marker here for others, I was able to successfully set up a RAID 10 partition using diskutil, indicating that the problem is Disk Utility itself and not the RAID implementation.
Disk Utility has proven itself to be bugridden (must restart frequently to get updated view of volumes; drops device names at various times; etc.) and this latest bug would seem to suggest that it should be avoided in favor of diskutil for any serious RAID construction.
