SSID disappearing from Aeronet C1240
Hi,
I'm having a strange problem in the office with one of my Aeronet C1240 access points.
My current topology is a hub-and-spoke with my HQ which contains 2 Cisco wireless LAN controllers with version 6 OS. I have 10 AP's, 2 of which are in the HQ building and 8 AP's spread over VPN using HREAP that are in our branches throughout the country.
The problem that I'm having is specifically related to one of my AP's and that is that the ESSID located on the management VLAN keeps disappearing from the device..... this seems to be a local problem as we haven't experienced any thing of this sort with any other branch in our topological setup. Currently we have 2 VLANs trunked to the AP, VLAN10 which is a guest VLAN that shows up without any problem and VLAN1 (management VLAN) which is for employees.
The ESSID from the management VLAN keeps disappearing and we can't figure out why this is happening as any configuration change has not been implemented and as stated previously seems to be a localized problem.
Checking the device output both VLAN's 1 and 10 are propogating to the device and each sub interface IP is ping'able.
I have never come across any issue like this before and am totally baffled by what the cause of this could be.......
Can anyone give me any advice or tell me which output is necessary to help debug??
This is the current logfile from the AP:

I just backed up my 3gs iphone using itunes. All my photos and contacts have disappeared from my phone. I am unable to locate them on my computer. HELP!!!
OK, I understand. Try this ... it's much safer. It will simply restore your backup, but not do anything to your iOS:
While your iPhone is plugged in to iTunes, right click on the iPhone icon on the left side of the iTunes display.
Choose "Restore from backup ..." from the pop-up menu that appears.
Again, what this will do is place that backup back on your iPhone without changing iOS. So you should be very confident in the backup contents before doing this. -

I have been using Firefox for almost a year now,and had upgraded to Version 7 recently.
My problem started with the downloads.
1) When a download is to be commenced,a box appears with two options,namely "SAVE" and "CANCEL".
Even when I click on "SAVE",the the box shows it as 'cancelled'.When I right click on the box,another dialogue box appears with a number of choices ,the top one reads 'RETRY'.
When I click this option the download starts and it is shown in the chosen location until 99% is completed,bu the moment the download is complete,the item i.e. the downloaded item just disappears from the chosen location and is not traceable thereafter.This has happened to me repeatedly over the past week or so and I am so disgusted that I have been compelled to uninstall Firefox,and have started using Chrome.
Please help,as I would like to get back to using Firefox again but without the above problems.Understood. However, the point that I'm trying to make is that it's not the WiFi access point's security that's in question, it's having your phone's WiFi in an always-on mode that's in question. It's simple: if your phone's WiFi is on, then it is both discoverable and hackable... even when it's not connected to a WiFi network or access point. Here's an article about a drone in London that was created to hack smartphone WiFi signals (and hackers have been doing what this drone does for years):
http://money.cnn.com/2014/03/20/technology/security/drone-phone/
The point is that it's not secure to have your phone's WiFi in an always-on mode. It would be better for privacy and security if Apple made WiFi location aware so that it is only enabled when you are at a trusted location (e.g. your home or office). Or, at least give us the option of location aware WiFi so that each user can determine the best mode for their phone:
(1) Always-On (current default - not secure and many privacy issues).
(2) Trusted mode (only on at trusted locations).
(3) Off. -
Tunes disappear from folder - but still play in iTunes???
I can play songs in iTunes that have disappeared from the iTunes music folder. Maybe I'm fundamentally misunderstanding something, but this has me baffled.
Here's what's happened: I was looking at my iTunes music folder in Finder. I double-clicked on a song (an mp3 file); iTunes opened and played the song. But when I closed iTunes, the song was missing from the folder!
I opened iTunes, found the song in the library, and played it again. I did a 'Get Info' in iTunes and it still shows the song as being in my music folder.
I used spotlight to search for the song name, and it, too, shows the song as being in the iTunes music folder.
But it still doesn't show up when I open the folder in Finder.
Worried that something was going wrong with the file structure, I did a clean install of the OS (10.4.11) and upgraded to the latest iTunes (7.5).
Since then, I've replicated the process with two other songs.
Any ideas?All of the PDF documents on my iPad disappeared. This seems to be a problem that a number of people have experienced, although a clearly documented solution does not appear to be readily available.
This issue can be resolved by deleting all the PDF documents in the iTunes library. Copying the PDF documents back to the iTunes library and then syncing the iPad will allow the missing documents to reappear back in the collections into which they were filed.
It is a good idea to make sure that you have a complete backup of all of the PDF documents in the library before deleting them. -
Downloads disappear from list immediately and automatically when download completed
Everytime a download completes it disappears from list automatically
Are you using Firefox 3.6 or Firefox 4?? Your "More system details..." link shows that you have turned off storing of history using a Firefox 4 preference (places.history.enabled), but your post says Firefox 3.6.17.
Anyway, the general history setting affects not only site URLs, but also downloads. To treat them separately, go to
Tools > Options > Privacy
and change to Custom history settings. Does that solve it? -
I recently bought a Galaxy Note 10.1 2014 edition and downloaded Verizon Messages. All of my conversations synced with my laptop and phone, but whenever I send a message from my tablet it immediately disappears from the conversation on all of my devices. The people on the receiving end still get the message, but I do not see it. Please help.
Hi Nickbon!
I'm sorry to learn of any issues viewing messages sent from your tablet using Verizon Messages. When did this issue begin? Were messages from your tablet ever appearing for you? Please share some details for me, thanks!

Apple TV2 Just Disappeared from Remote app on iPad and iPhone after latest Remote app update
I Have used Remote app on my iPad and iPhones to control my ATV1, ATV2, and ATV3 for years. After the latest Remote app update ATV2 has disappeared from tRemote, and I can no longer find a way to connect it. Any advice about this?
Brilliant. Restarting did the job, and all is well. Since I have recommended this to others with other ATV problems, I'm a bit embarrassed that I didn't try it myself at the outset, and would probably have come around to trying it later, but you saved me some time. Thanks.

Songs disappear from playlist once in a while but are still in library
Every now and again I notice that a song has disappeared from a playlist. I can copy it back to the playlist from the music library. But what makes the song drop from the playlist? It's either a song I purchased from iTunes or one I imported from cd. Doesn't matter.
Not a Sony Vaio. I have one of the first iPods. It was a gift. It's not that songs disappear from the playlist in the iPod, but from playlists on the computer. They are in the music library and I have to copy and paste them back into the playlist I want them in. I haven't lost any from the music library, fortunately.
The playlists (I have a bunch of them) are blue with a music note. The songs in the playlists have checkmarks next to them, and are all checked. They just drop out of a playlist every now and again and I have to copy it back in. I can go for a while and think "hey, I haven't heard X in a long time". And sure enough it's dropped from the playlist in the computer, and I have to copy it back in from the library, then resynch the iPod. Really weird and mildly annoying. -
Why is it that when I delete an email message from an account on my iPhone it instantly disappears from the same email account on my wife's iPhone? We both have iOS7 and have imap email accounts.

HT3281 Podcasts disappeared from iTunes library and iPhone podcast app.
All of my Podcast subscriptions and content suddenly disappeared from my iTunes library and from the Podcast app on my iPhone. Checked iTunes to make sure it's running the latest version of software, and it is. Music library appears to be OK. How do I fix this and get my podcasts back?
This just happened to me this morning. I sat down to update my podcasts, and discovered that every podcast I was subscribed to that had any recent episodes (I'm thinking since the first of this year, but no way to tell a definite date for sure) had disappeared. When my iPhone synced, they disappeared from it, as well. I looked them up in the iTunes Store podcast directory, and had to resubscribe to every one of them. And some of them only make a limited number of old episodes available in iTunes, so I've lost some without ever getting to listen to them.

Files disappearing from mounted .DMG files
Hi, I've had this issue occur a few times in Tiger and I'd like to know if anyone else has experienced this and if there's a known workaround. Sometimes, when browsing a disk image, or, less commonly, a physical disc like a CD, files in the Finder will seem to disappear from the image/disk when clicked on. First the filenames will go, then the files themselves, and evidently those files then become unreadable in general as applications can't access them. I don't get any error messages; it's just like the filesystem on that disk eats itself away and vanishes. I can unmount the disk without any issue.
I'm having this problem right now with any disk image I mount on my XServe -- it goes through the "Verify" step just fine, shows up on my desktop, I can browse and even open files, but inevitably within a very short period of time the above occurs, and it becomes useless. I KNOW it can't be the .dmg file that's the problem, because if I share the .dmg over Personal File Sharing and mount it from another Mac, this problem does NOT occur. It's just on the one Mac hosting the files. Any idea what this could mean, and what could solve it?
Also, I know a lot of times a restart will cure this weird little glitches, but I would really like a solution, if you know what I mean... particularly on a server, I cannot afford to restart whenever I have a problem.Sounds like you have run into a very strange, and unfortunately no uncommon, bug involving file systems from either servers or FAT 32 mounted external drives.
