Sudden/intermittent lost connectivity

I just got a new ibook with an Airport Extreme card. My router is Linksys. Twice now, I've had sudden loss of connectivity, and the only thing that restores it is restarting the computer. (Renewing the DHCP lease may also work.) I have NEVER had this before -- on my old ibook, I had an old (non-extreme) Airport Card, with the same router. I DID upgrade to Airport 4.2 on the old computer, and did not experience any problems. Any thoughts?

From your other post, start broadcasting your SSID and see if that makes a difference.

Suddenly lost connection to my wifi and my phone can't find it again?

I was just using my iphone 4s normally and it suddenly lost connection to my home's wifi. I have been trying for hours, reset the wifi modem and turned it on and off, put my phone through recovery mode- the whole lot. Please help!!!

Howdy whitneyavon,
It sounds like you are unable to either connect to, or see your home Wi-Fi network. I would first, update your router, then reset your network settings. Assuming you restored from a backup, my thought is that the backed up network settings may need to be refreshed:
Update your Wi-Fi router to the latest firmware2. For AirPort Base Stations, install updates using the AirPort Utility.
Reset network settings by tapping Settings > General > Reset > Reset Network Settings. Note: This will reset all network settings including:
previously connected Wi-Fi networks and passwords
recently used Bluetooth accessories
VPN and APN settings

FiOS Quantum Gateway Router - Intermittent Dropped Connections

I just got this router and incredibly disappointed!! I had the Arcotec.. Excuse my spelling and was having intermittent problems with that but this new a Gateway is herendous!!! I can't believe they charge you a 199 for this. Wifi signal lost constantly. Called tech support.. Now they want to charge me 75 bucks for an extender that they say will help.. Optimum looking better all the time!! Very frustrated.

I am experiencing the exact same issue. My issue also started after i upgraded to their 50/50 plan and swapped out my Actiontech M42xxx for the Quantum Gateway Router. They had me do the following and i am still having the issue. 1. disconnect the coaxial cable and the power from the router2. Reset the fios box in my garage by unscrewing the battery power and removing the battery3. Replaced the router (Verizon did this and the replacement was another Quantum Gateway)4.

Hi All, I upgraded my FiOS service a couple of weeks ago to the Quantum 50/50 service and bought the Quantum Gateway/router (model# FiOS-G1100). I used to use the Actiontec router (model# MI424WR, Rev. I). I've been having issues probably for months with intermittent or dropped connections on both wired and wireless connections. Fast forward to the beginning of December. I called tech support enough to the point of them sending a tech out to look at it. My ONT was old, and he replaced it. I had hoped that this was the issue, but it wasn't. The drop-offs continued. I again hoped the upgrade in service and router would also fix the issue. Nope... didn't. This 'latest, most powerful' router only has two lights on it, one for wireless signal and the other that looks like a globe. The router sits on my desk, so I can watch the lights. While I am surfing around, the globe light will suddenly flash for about 5-10 seconds. While this is happening, my connection drops/stops, and then resumes a couple of seconds after the globe light stops blinking. I also noticed that the globe light will turn red once in a while, but not nearly as often as the blinking white does. It's not really consistent as to how long I can be online before the connection starts dropping. I haven't honestly watched it for a long period of time (in other words, I don't know if it's still doing it while I'm not at the computer). I just notice it while I'm trying to use the connection. Once the router starts disconnecting, it can happen as often as every few minutes. VERY annoying. My setup is:2 Mac laptops (one used wirelessly and one used wired connected to a display)1 Apple TV (wired)1 Apple Airport Express (wired)1 printer (wired) I don't have any cordless phones, powerline adapters, wifi extenders, or other electronics that might be messing with the signal. I use VPN software but haven't noticed a difference with it on or off (I think). Any thoughts as to what this might be or where to look? Thanks in advance. I am still having the issue. there is obviously an issue and either Verizon knows about it and doesn't want to say they know there is an issue and fix it, or they are too dumb to take the time to find out. Each time i call i give them detailed information on the issue and ask them to check their knowledgebase if its listed as a know issue and they keep saying it's not. The issue happened again tonight, 1/8/15. at first my laptop dropped Internet connection while i was surfing. then i checked my other wi-fi devices and they all lost connection. i then went and checked my wired devices and they too lost connection. I look at the router and this time both the Globe Internet and the Wi-Fi lights were solid white. i looked at the Internet Ethernet light and the bottom light was green. I could have resolved the issue by unplugging the router and plug it in back, but instead i called Verizon so they could see the issue. 10 minutes into the Verizon call queue the Globe Internet light changed from solid white to solid red. 5 minutes later i finally got to speak to a tech. at first he said the box in my garage wasn't connecting to the router and asked me to disconnect the coaxial cable and the power and, according to him, he sent some command and instructed me to connect the coaxial cable and power the router back on. I did that and then the issue went away.I told him the rootcause of the issue was not identified and fixed and the issue would occur again and i needed him to alert engineering or product development about the issue. i then told him its a know issue with the router and he should do a google with "Verizon Quantum Gateway dropping connection" and he would see how many people are having the same issue. I told him Verizon need to take their heads out their A*%%%$ and spend some time and investigate and resolve the issue. Me

My FaceTime won't connect. Every time I try to call my friend it says connecting. Then unable to connect. Or lost connection. And when I go to our FaceTime history it said "FaceTime answered on another device." What can I do to fix this problem?

Lost connection to mobileme galerie

Today suddenly iphoto lost on one album the connection to mobileme galerie. The content is still on the web, but the ( sync ) folder in iphoto is empty. If i drag a new photo/movie , actually this folder contains movies, to the folder it will upload to the galerie - thats fair enough - but afterwards the folder in iphoto is ( again ) empty. Anyone else experience the same thing ?

I got in touch with Apple - for about an hour. Despite the Support team not admitting to anything at this stage, it came across to me very clearly, that the MobileMe IT does not cope very well with any combination of these scenarios:
- poor or random bandwidth
- interruptions in the connection.
- large quantities of data in combination with the above two points
I had the opportunity to re-upload a large set of photos from a higher capacity broadband connection. Result: no problems.
The fundamental technical issue, in particular for those with poorer broadband connections: The software & the MobileMe service do sometimes fail to stay connected and more fatally the software somehow loses the URL of the gallery.
The fundamental functional/managerial issue: Neither the desktop software nor the MobileMe web service make the user aware of what happened and fix the problem. SO IT’S GUESSWORK FOR THOSE AFFECTED.
Coming back to the Apple Support, I guess they will ultimately understand and fix the issue. However the process to get to this point appears to be long-winded, as there are many procedures and a lot of communication involved until the message finally reaches those, who understand and manage this product.
In the meantime the best bet is to only use broadband with high capacity uplink, if large sets of data (photos, videos) ought to be uploaded.

HT5706 every since i have had my apple tv it always stops in the middle of everything and says i have lost connection.

i am very disappointed. i should have sent it back, but i thought it was something that i was not doing right. I will be watching a movie and then all of a sudden it says i have lost connection. i was going to buy another one, but i am scared to buy another one.

Hello there, ermafrompaola.
The following Knowledge Base article offers up some great, practical steps for troubleshooting connectivity with your Apple TV:
Apple TV (2nd and 3rd generation): Troubleshooting Wi-Fi networks and connections
http://support.apple.com/kb/TS4546
Although the entire article is very useful, the following section may be helpful in your circumstance:
Apple TV unexpectedly disconnects from the Wi-Fi network or signal strength is weak or fluctuates
Check for any obstructions and adjust the location of your router or Apple TV; also check for sources ofpotential interference.
Update your Wi-Fi router to the latest firmware.For an AirPort Base Station, refer to this article for information about firmware updates. For third-party Wi-Fi routers, check the manufacturer's website for details on updating your firmware.
If after attempting the above steps, your Apple TV is still unable to connect to your Wi-Fi network:
Restart your Apple TV: Choose Settings > General > Restart.
If you can connect to the Internet using an Ethernet connection, verify that your Apple TV is using the latest software by choosing Settings > General > Software Update. If your Apple TV can be updated, install the update and test again.
Thanks for reaching out to Apple Support Communities.
Cheers,
Pedro.

Bluetooth Mouse "Lost Connection"

I keep getting a "Lost Connection" message with my bluetooth mouse even though I have plenty of battery life left? Does anyone know why or what I can do? Thanks!

Steven,
I had the same symptom. I found that there was a problem with there not being enough pressure being applied by the metal strip inside the mouse cover to the switch next to the laser. It was intermittent enough that it would lose contact every so often, making the mouse think that it had been switched off.
Making a slight bend in the metal strip so as to keep more pressure on the switch seemed to solve the problem.

IPhoto lost connection to Library

I've had my iPhoto Library on my external hard drive for quite some time without problems. But suddenly, iPhoto has 0 photos. It seems to have lost connection to the Library completely. The photos are all still in tact on the hard drive. But how do I re-connect the 2?

Hold down the option (or alt) key key and launch iPhoto. From the resulting menu select 'Choose Library' and point it at the Library on the Externa.

Lost Connection problem

Hi all, new here
Anyway have had BT Broadband for a couple of years now, had no real issues until Thursday, when we lost connection, I have a HH2 and all the Blue lights were fine, but none of the PC's in the hosue would connect to the hub all of a sudden 1 x desktop, 2 laptops and a netbook, although the net book did connect off and on for about 10 - 15 mins, but only at about 150 to 200k (not 2MB)
spoke to the helpline, went through all the usual tests, and they said in the end the HH was naff, and would order another, thus been without internet since Thursday (This one is at work !)
I did find an old HH v1 (white) on Sunday, plugged that in... same result no connection from any of the pc's, well not for more than about 10 mins max, this make me think it may not have been the hub? if not does nayone have any ideas??
Have changed the filters, and the phone line itself seems clear, BT tested it and said it's all OK

Hi Swills,
Welcome to the forum and thanks for the post.
It seems odd that you are having the same problem with a different router, seems to me that it may not be the router at fault at all. I cant be sure until I run a few checks.
Can you please drop me an email to [email protected], include your BT account details and link to this thread. I will see what I can do.
Cheers
Sean

Lost connection when attempting to setup asdm

Hi everyone,
I was vpn in and log onto my local desktop. I putty into my ASA and was in the process of configuring my ASA for asdm.
I had just input...
nameif inside <enter>
ip add <default gateway 255.255.255.0> <enter>
and I sudden lost connection to the desktop and now can't remote or ping my desktop and other servers on the network (use to able to).
I can still vpn in though..so not sure what the heck is going on. Did i set up "ip add..." wrong? Big Help please.

We do not have enough information to be sure about what the heck is going on but it sure does sound like you changed the IP address on the inside interface and that now devices on the inside (including your desktop) are attempting to communicate with the ASA using an address that is no longer the address of the ASA.
One thing about this situation that puzzles me is that if you were configuring the ASA for ASDM how does that lead you to configure an IP address on the inside interface? To enable ASDM you need to be sure that the correct version of ASDM code is loaded in flash, you need the configuration to point to that ASDM file, and you need to specify what source addresses can use ASDM.

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. 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
The 10.5.8 COMBO is here
