A lot of hang-ups and disconnected WRT120N in all installations with multiples Wireless Routers

i'm so tired, i have a lot of installations (school, university,..) that have various WRT120N (4,6,8,12,...) all routers have the latest (no is very new) firmware 1.0.0.4 build2, and in a installation all routers have the same SSID and diferents channel.
Every day all routers hang-up and the user need to stop and start every router.When a router hang-up this can't receive any ping, telnet,web,... across the wired LAN (ping timeout) but all links seem correctly and SSID is published.
I try another brand in this scenario and work fine.
I try to chat with linksys support but is'nt possible, nobody know my problem ?

Sorry I missed the Access Points description - I'm wondering - because there are so many routers - if there may be an issue with the channels and wireless overlap. One IEEE 802.11 "N" can typically communicate within a radius of 70m indoors 250m outdoors. However, the actual range of communication can vary significantly, depending on such variables as indoor or outdoor placement, height above ground, nearby obstructions, other electronic devices that might actively interfere with the signal by broadcasting on the same frequency, type of antenna, the current weather, operating radio frequency, and the power output of devices. I'm thinking that you will have to separate the channels on these ... I don't know for sure why the other routers worked - maybe only one was changed at a time instead of all the routers in the whole network ... at any rate if you have overlap on frequencies there may be something there ... especially when using these as AP's. I believe this router has the ability to change frequencies in the the advanced wireless settings under the wireless tab.
Just shooting from the hip here.

Clips hang up and repeat on Blu-ray disc with multiple clips

I have developed a DVD for background videos at my office.
It has 44 clips on it.
Only a few will play.
I have tried it on 4 different BluRay DVD players = same result.
I have burned the project 5 times = same result.
Why does it stick?
Using the fastforward button on the remote controll shows all clips are there.
Sometimes it will play 8 or 10 clips before sticking.
Then it repeats the same 2 clips forever.
Please help me.
Rob

Rob,
Could not find the screen-caps. If they are JPEG or PNG, just use the little "camera" icon in the editing page to "attach" them, or post a URL for others to view them from a server. This ARTICLE will give you some tips on screen-caps.
Thank you for the info, and the description of what you wish to have happen.
Now, what are the End Actions for each Timeline? If I understand what you want, the End Action for each Timeline should be to the next, and for the final Timeline, back to the beginning of Timeline 1. That will create the "looping."
Check carefully for any Overrides, and make sure that each is set to "Not Set."
Good luck,
Hunt

You installed adware along with something else.
You can either follow Apple's manual instructions for removing it, or use the free automated tool, AdwareMedic.

I downloaded Yosemite and now I have lots of pop ups and my safari isn't working correctly. How do I remove Yosemite?

I updated to mozilla firefox 18.0.2. the fox is gone, but there are lots of pop-ups and no way to disable them. i want to TALK to someone, please

Last week i downloaded Filezilla to edit my web page. When i did so, the firefox page looked weird -- there was no fox. The page has a WhiteSmoke icon instead. So i updated to mozilla firefox 18.0.2. The fox is still gone, but there are lots of pop-ups and no way to disable them. i want to TALK to someone, please

Sorry this is really your only support option. The live chat support option was closed down last year.
Maybe attaching some screen shots will help us understand your problem. I am not sure I understand about ''the fox is gone'' & ''he page has a WhiteSmoke icon instead. ''

My iphone4 when connected to any computer will not charge and is constantly connected and disconnected. does the same with itunes. Also i'm talking on the phone and all of a sudden the other person can not hear me.

My iphone4 when connected to any computer will not charge and is constantly connecting and disconnecting. It does the same with itunes so it doesnt really sync. Also when talking to someone, all of a sudden they cant hear me.

I'm having the same issue. I went to my local apple store and they could not work me into the genius bar so i made an appointment for tomorrow morning. The clerk did check the phone for the pink indicators at the top and bottom of the phone (where you plug in your USB or headphones) He said if you can see a pink indicator dot you may have gotten it wet, or had some sort of condensation in it, which could cause the plugs to not work.
In regards to people not being able to hear you, i'm waiting for my appointment tomorrow for more news! I would recommend taking it into your local apple store for more answers.

All iPhones constantly connecting and disconnecting from 2014 MacBook Pro with retina display

So I have an iPhone 6, 4s, and 3gs, whenever I plug any of them into my MacBook pro they rapidly connect and disconnect. After about 20 seconds of doing this they trackpad and keyboard stop responding and won't be recognized until I restart the laptop.
Just as more information I have used 5 or 6 different cables and it works fine with my LG G3 and every other usb device I use. I have iTunes updated to 12.0.1 and OSX updated to 10.10, and this has been happening for about 2 months or so. My iPhone 6 is running 8.1 but did this before, although with the first sync when I first got the phone it worked fine.
Any information would be helpful
Thank you

I'm having the exact same issue with the new 2014 iMac 5K Retina i5. iPhone 5 and iPhone 5s both work flawlessly.

For all those with D-Link routers and problems with iTunes dropping AppleTV

My setup: Custom built WinXP PC with iTunes 7.6.2. Apple TV w/Take 2. D-link DI-624 wireless N router, wired to the PC, wireless to the aTV.
I have an intersting phenomenon occuring with my Apple TV. I can sync the aTV to my PC and it works fine, but the first time we receive a phone call on our VOIP phone, the router drops the ATV connection to the PC. aTV still has internet connectivity, but iTunes on the PC cannot see the aTV, and I cannot sync.
A search yielded gobs of folks with D-link routers and iTunes/AppleTV connection issues. I just won an Airport Extreme router off ebay...as soon as I have a chance to test it out I will post back in this thread as to the results.
I know folks don't like the solution to be "spend more money", but I think it would be worth it to a lot of people if they knew a different router would solve their issues (rather than continuing to guess or throw money at the problem randomly).

I have a WinXP PC and a Linksys G class router. I am on Comcast broadband cable. Both ATV and PC are on wireless link. And I have tried a borrowed Apple Airport router (G class). That didn't help resolve this problem so far. I don't think it is a router issue as you will see that many folks on this forum have the same problem with a wide mix of environments. Many of them are on pure Apple components and so one cannot blame Microsoft and non-Apple devices.
Having said this, I hope the new router resolves your issues. In my case, the only option left is to keep calling Apple Care.

For some reason, my compression option is grayed out under "File" menu, and when I select a folder with multiple files, or multiple documents, and try to right-click or tap the mousepad with two fingers, I do not get a "compress" option available. Help.

I don't know why, but when I select a folder with multiple docs contained within it, or multiple files, the Compress option is grayed out under the File menu, nor is it available when I right-click. Please help.

Yes it is, but I have the same problem of the option does not appear with "right click" (I'm actually control-clicking), and COMPRESS is grayed out under the file menu. I'd like to fix it.
Hmm. After finding the Archive Utility,* I tried archiving the folder. It came out as .cpgz, ugh. Found there was a preference to make .zip the default. It worked!
And now…the menus are not grayed out. ?!?! OK.'
Hope this helps someone.
*You cannot find this via search, apparently it is a hidden file, you have to click from the root drive through to /System/Library/CoreServices (Thanks for the file path Alberto!)

Installation with multiple as and one DB (no cluster)

Hi, I'm trying to setup a production environment with three Jboss AS non-clustered and one MSSQL database. I've made the installation on each AS and for each AS I've executed all the steps of the Configuration Manager.
Now I have some problems about the three AS line up; when I modify an user password on one AS the other don't see this modification. Moreover, some common features works such as the policy definition; for example, when I create a policy on the first AS the others can see this policy.
Can you help me?
Thanks
Fabio

Multiple, non-clustered LiveCycle instances against a single database is neither tested, nor supported. For each instance, you'd need a separate database (with multiple sets of tables, views and sequences). All changes have to be repeated for every instance you have.
This technical whitepaper from Adobe will provide more details:
http://www.adobe.com/devnet/livecycle/pdfs/lc_platchoice_wp_ue.pdf
What you are attempting is a deployment architecture the author of this whitepaper calls "Server Load Balancing" (see page 11).
You might be better off clustering the three instances.

Safari 5.0 Upgrade Slow and Lot of Hang-ups

I'm new to the Discussion forum. I joined because of issues I'm having with Safari 5.0.
I installed an auto upgrade to Safari 5.0 from ver. 4.0.5 yesterday. Immediately I started having problems with slow loading of web page, incompletely loaded web pages, could not use more than one file tab, and network disconnecting.
I called Apple support under my APP and they had me run v4.0.5 as the User Agent under the current 5.0 version by going to the Develop menu in Safari.
The steps were as follows;
Develop=>User Agent=>SAFARI 4.0.5 - MAC
(You may need to re-boot after this).
This appears to have "fixed" all of my issues!! But the fix was to basically go back to v4.0.5 by the "long way".
I was told Apple was working on a fix for 5.0.
I saw quite a few similar posting having the same problem.
Has anyone else tried this fix using the User Agent as v4.0.5?
Are there any downsides to this?

Safari->Preferences->Advance->on the bottom. To get the Debug menu which includes a listing of Keyboard & Mouse Shortcuts, among other useful things, run this in the Terminal app and quit & relaunch Safari:
*defaults write com.apple.Safari IncludeInternalDebugMenu 1*

Lots of hang ups when using iPhoto in full screen mode

Has anyone else got this problem or a solution? I find that iPhoto hangs up or give strange action when in ful screen mode. The other day, for example, I had two iPhoto windows showing, one in full screen and one normal window on the desk top! Another day the system became unresposive and I had to force quit iPhoto to get it back. Another day I had to re-boot the machine entirely. All other full screen apps work fine.
I am on MacBook black, 2GB memory. OS X Lion fully updated.

Try trash the com.apple.iPhoto.plist file from the HD/Users/ Your Name / library / preferences folder.
(On 10.7: Hold the option (or alt) key while clicking on the Go menu in Finder to access the User Library)
(Remember you'll need to reset your User options afterwards. These include minor settings like the window colour and so on. Note: If you've moved your library you'll need to point iPhoto at it again.)
What's the plist file?
For new users: Every application on your Mac has an accompanying plist file. It records certain User choices. For instance, in your favourite Word Processor it remembers your choice of Default Font, on your Web Browser is remembers things like your choice of Home Page. It even recalls what windows you had open last if your app allows you to pick up from where you left off last. The iPhoto plist file remembers things like the location of the Library, your choice of background colour, whether you are running a Referenced or Managed Library, what preferences you have for autosplitting events and so on. Trashing the plist file forces the app to generate a new one on the next launch, and this restores things to the Factory Defaults. Hence, if you've changed any of these things you'll need to reset them. If you haven't, then no bother. Trashing the plist file is Mac troubleshooting 101.

Even though in my Mac Book settings pop up blocker is on, i am getting lot of pop ups and security alerts from mackeepar on every click i do on the screen. how can i clear that issue?

i have a mac book 13" 0f 2010, when ever i click on the screen a pop up of google survey, lottery or security alert of mac keeper pops up. i have pop up blocker on in the settings. how to clear is issue. is that a security threat to my system? please help.

One of the most common pieces of adware that causes MacKeeper pop-ups is Downlite, and if Mark is infected with that, it will prevent him from loading the AdwareMedic website. If that happens, see:

Hang ups and jerkiness in iMovie HD export to mini dv camera

I have a big problem-- while I am trying to export a TV show created in *_iMovie HD 6.0.3 (267.2)*_ to my *Sony DCR TRV-900*, which I have done many times.
Suddenly, there is jerkiness upon export to my camera. My iMoive video which plays back normally on the coputer looks jerky and almost slo mo while going to camera, and is also like than when the mini dv is played back. However the audio quality seems to be ok on the mini dv.
FYI, this show is made up of a series of Full Quality Quicktime chunks (ie individual scenes that I made and exported thru iMovie as Full Quality QuickTime, and then re-imported as individual Quicktime video chunks so not to tax the exporting capacity of iMovie too much).
The show is about 26 minutes, and the size of the iMovie file is about 26 gigs. The file resides on a Maxtor external drive with firewire 400.
I have plugged and replugged, turned camera on and off, and changed mini dv tapes a couple of times...
Does anybody out there know what is up with this jerky outputting problem?
Thanks
Michael in LA

Not sure why you should have this problem now, but you can export the entire movie as a new Full Quality Quicktime, and then reimport that into a new iMovie and export that new iMovie to your camcorder.
Just be sure you have enough free space on your hard drive where your iMovie is located.
.....that MIGHT be the problem with the jerking......how much free space do you have?

Hang-ups and chaos in tiger?

Hello, Starting yesterday all of my programs started having the beachball rolling. I have had to forcequit all of them at various times. Sometimes I waited 20 minutes before they actually were usable. But once they are up, they are very slow.
I have repaired permissions and did do a techtool delux scan that came up with this message.
Surface Scan
Failed (Error = -4)
The Surface Scan test will scan the disk for bad blocks. TechTool Deluxe can map out the offending blocks so that they are not used in the future.
Media defects cause this test to fail. You should consider backing up the device, reformatting the media, replacing the data, and then testing again.
However, even my expose, and techtool end up floating the ball... I can get to email if I wait 20 minutes, so at least I can post this.
Any ideas? Never had this problem in Panther? And it is slowing my production down completely. Save me!? Any help would be deeply appreciated. thanks!

Hi Michael, I wouldn't worry yet. TechTool Deluxe is not compatible with 10.4 Tiger you should contact AppleCare for updated disks.
