Internet/Shared Drive just goes down

This has been happening for the past few weeks. I will be surfing on my laptop as well as being connected to a shared drive that is connected to the Airport Extreme Base Station. Suddenly...everything just drops. I am still showing a strong connection to the base station and my IP seems to be the same as when I first connected. However, all internet access and the shared drive just disappear. This will continue for about 3 minutes and then...everything is back to normal.
Not sure what is causing this or what steps I need to do to fix it. Obviously it is very annoying.
Any help would be appreciated.

Happens to me all the time and it's driving me insane. In fact, it just happened a couple of minutes ago.
What's even more annoying is that I went out yesterday and bought a new Airport Extreme router to replace my Belkin Pre-N router, because of precisely this problem, thinking (hoping) that it was a router issue.
Clearly it's not, as it's happened several times today. There HAS to be a way to fix this, no? I keep losing my video iChat sessions, getting interrupted during downloads, screwing up backups to my network drive, etc etc. Infuriating.
Help, anyone?
Thanks,
Steve

AP 1200 Just goes down hard

We have a 1200 Aironet just go down hard for no reason through out the day, we replaced the Power Injector with a C2960 POE Switch, we also replaced the cabiling. When it goes down hard all three lights are still green as if the AP is still up. We verified the IOS with other stores and everything is the same on the configurations, versions, and IOS.
Can anyone give us a suggestion on what the issue or something else we can look at that we might be over looking?
Couple more things that we have done:

Thanks in advance......

Hello John,
As per your query i can suggest you the following solution-
Please check the POE for the AP and whether it is proper or not.
Types of Power over Ethernet
This section describes various types of Power over Ethernet (PoE) including Cisco pre-standard power, IEEE 802.3af power, and IEEE 802.3at power.
Cisco Pre-Standard Power
The first generation of Cisco pre-standard PoE was designed to power devices such as Cisco IP phones and access points. This pre-standard solution had relatively low power requirements (approximately 6 to 7 watts). Later generations of pre-standard power supported higher power modes (up to 15 Watts) and added power negotiation via Cisco Discovery Protocol (CDP). In July 2003, the IEEE ratified the 802.1af standard (up to 15.4 watts of power). With the ratification of IEEE 802.3af, Cisco supports both IEEE 802.3af and Cisco pre-standard PoE concurrently. Cisco has also extended pre-standard power management using CDP negotiation to Cisco IEEE 802.3af compliant devices to further optimize Power Source Equipment (PSE) power management.
When using a Cisco pre-standard source for power, it is important to check the power draw in watts (Table 1) and verify that the PSE can supply enough wattage to the powered device. Depending on the version of your PSE, enough power may not be available to supply some of the newer access points.
IEEE 802.3af Power
The IEEE 802.af-2003 PoE standard:
•Defines terminology to describe a port that acts as a power source to a powered device.
•Defines how a powered device is detected.
•Defines two methods of delivering PoE to the discovered device requiring power.
•End-Point PSE—PoE-capable Ethernet port. Power may be delivered by an end-point PSE to a powered device using the active data wires of an Ethernet port or the spare wires. An end-point PSE, such as a PoE-capable Ethernet switch may implement either scheme.
•Mid-span PSE—Can be used to deliver PoE if an existing non-PoE-capable Ethernet switch is used. If a mid-span PSE is used, it can only implement power delivery over the spare pairs of the copper cabling and cannot be used to deliver PoE over 1000BASE-T connections.
Hope this will help you.

Hard Drive Space goes down when I turn on AirPort and go online.

So, when I turn the AirPort on on my MacBook Pro you can see the hard drive space go down on the bottom of a finder window. When I turn AirPort off the the GB available on the hard drive stays the same. I'm not downloading anything. that I know of. Is some virus downloading in the background that I can't control? I did a full scan with VirusBarrier Express and it says that there are no infected files on the computer. Any help would be greatly appreciated. Thanks!

Welcome to Apple's discussion groups.
Launch the Console utility and look in the "All Messages" category for repeated messages. If you see such messages but you don't understand what they mean, copy a few of them and paste them into a reply to this thread.

That's extremely doubtful.

IMac hard drive keeps going down and now will not boot up.

This is my first post here so I hope I am in the correct area. I recently purchased a iMac 24" Intel Core 2 Duo Processor, 2.16GHz, 2GB RAM. It ran well at first but now I keep getting errors that say "There has been a problem with your system, you must turn off the computer by pressing and holding the power button on the back of the panel". This has been happening more and more often.
I took it to a local Apple auth repair shop. The guy looked at it for 10 minutes, said everything is fine and sent me home.
Now when I turn the computer on all I get is a blank white screen that never changes.
I just switched from PCs to Macs, I have to say that I am more then a little frustrated with how poor the computer has been. Does anyone have any suggestions on what I should do now. I do have the Applecare for another 26 months. Thank you.

"There has been a problem with your system, you must turn off the computer by pressing and holding the power button on the back of the panel".
This means Mac OS has crashed. Mac OS shouldn't crash too often. You should give applecare a call. They'll probably tell you to re-install the OS.

Wireless APs going down randomly

Hi All
We have a situation where wireless access points are just going down randomly on our network. The situation is as follows:
We have 2 Cisco 5508 WLCs (licensed for 250 APs each, with more licenses en-route), both running software version 7.2.103.0. Then we have a large-ish number (±300) of Cisco AIR-CAP3502I-E-K9 APs connecting to these two controllers. The APs are either connected to Cisco WS-C2960S switches, or in "older" areas of the network they are connected to WS-C2950 switches. We do not have PoE switches installed yet, so all APs are powered by power injectors (AIR-PWRINJ4=).
Anyhat, all the access points are in FlexConnect (previously HREAP) mode, and they all connect via trunk ports to the switches in order to get the VLAN per SSID working. Both controllers are in the same mobility group, and both are in the DNS as "cisco-capwap-controller" as they are load balancing. The APs are installed about 25m apart in most areas. There is one installation where two APs are about 10m apart, but this is due to the shape of the building in which they are installed. We have no autonomous APs deployed at all...
The problem is that some access points work for about a day, and then they just disassociate with whichever controller they were associated to, and then they just fall off the network completely. Both WLCs, the NCS, and the network monitoring system (WhatsUp Gold) show the affected APs as physically unreachable. Looking at the trunk port on the switch, it shows that the port is up and the line protocol is up, input rate is 0 bits/sec, and output rate is up to 70,000bits/sec. There are no input or output errors on the switch port. Here is the output from one such switch port:

Connecting a console cable to an affected AP is fruitless, as the AP appears to be unresponsive while it is "down". Rebooting the AP, then connecting a console cable works, but then you've lost your syslogs. Looking at the Ethernet interface on the AP, it appears as if the interface is picking up a lot of errors, especially CRC errors, which would indicate a physical cable problem.
I got our cabling contractor out to do a cable test again, and it passes every time. We have them test both the Systimax and the Molex cable installations of affected APs, and all is OK. They use a Fluke MicroScanner² cable tester which certifies the Cat 6 cable from patch lead to flylead. No problems there, and I trust that the cable is 100% as tested.
So I swap the power injector of an affected AP (let's call it AP A) with an AP that is not affected by this (let's call this one AP B), and AP A goes down again after a day, or sometimes only a couple of hours. AP B remains operational as usual. If I swap AP A out with a new AP (AP C), then AP C starts showing the same symptoms after about a day, and then it also just goes down. When "suspect" AP A is installed somewhere else, then it works and stays operational for, well, 58 days now. Changing the switch/switch port also makes no difference.
This happens to one of the APs that are part of the "10m apart deployment", but it also happens to another AP that is completely on its own in a building far away from any other wireless source, so I cannot think that this could be the problem. I happens to an AP that is less than 100m away from its closest WLC, and it happens to an AP that is more than 350km away from its closest controller. All the other APs deployed in our remote campus (350km fibre link) are 100% OK. It happens to APs connected to the older WS-C2950 switches as well as the brand new WS-C2960S switches.
I am at wits end with this one. Where could the problem be? I trust the "Big Green" company that does our cable installations, and I trust the equipment they use. I also trust both Systimax and Molex to be very good products. And I do trust Cisco, as this is the only network equipment we deploy.
Where to from here?
Regards
Connie

This issue has now been resolved. Details can be found here: http://www.cisco.com/en/US/partner/ts/fn/635/fn63537.html.
Here is the short version:
Problem Description:
Calibration between DRAM and processor on AIR-CAP350x and AIR-LAP126x results in Access Points (APs) failing to boot properly. One symptom includes a white LED and no console output.
Background:
The root cause is the DDR memory calibration process that was performed on the Access Points (APs) at the time of manufacture. The fix recalibrates the existing memory hardware, so it will operate more reliably.
Workaround/Solution:
The fix for this issue is now publicly available. Go to www.cisco.com to obtain Access Point (AP) IOS code version: 15.2(2)JA or later and/or WLC software version: 7.0.235.3 (or later 7.0 release), 7.2.111.3 (or later 7.2 release) or 7.3.101.0 (or later 7.3 release).
As of June 2012, new AP3500 and AP1260 products with version ID (VID) V02 are free of this issue.

Disappearing shared drives

I've been pouring over old forum threads for two hours and have STILL not found a fix for this, so it's time to ask the Spiceworks pro's.I work for a university and we offer shared storage for all of our users. Everyone is on the domain, and the drive mappings come from GPO's on a 2008 R2 DC. Each user typically has a dept. shared folder (maps through GPO) and a personal storage folder (maps though home drive from profile); both are always specified as different letters so there's no conflict there.If you're working on our wired network, everything is peachy. No problems at all. However, once you log into a laptop using wireless, the shared drives just vanish without a trace, completely. If you're on the university wireless or using the VPN, you can map them manually; but with 400+ users on this campus that's not an option.We tried...
This topic first appeared in the Spiceworks Community

Solved own problem. Somebody in the office, concerned about how even light contact could cause the handle for the internal hard drive bay to pop out, thought it would be a good idea to use the hardware lock. When the hardware lock is on, the system won't recognize external hard drives. Found out the hard way that when the hardware lock is on, and the X-serve is rebooted, it wouldn't recognize any hard drive, or even the internal DVD/CD drive.

Hard Drive connected - Space Available never goes down when deleting files?

I have tried 2 different USB drives connected to the new airport N router.
Both drives work fine, an 80 GB maxtor, then replaced it with a 500GB usb seagate drive. Both drives have the same problem.
I only hook one drive up and copy over files to the drive. The space available shows up fine, but when I delete any files, the space available never goes down.
Any ideas how to fix this or is this just a nice big glitch?

Anyone with a hard drive connected to the N router.
Just copy some files the drive, then delete them while watching space available. The space available never goes down. What gives? Anyone else seeing this problem?

Quicktime codec does not work, internet explorer just shuts down!

I have reinstalled quicktime many times and still I cannot view any videos or movie previews on internet explorer that use the quicktime plugin. When I open the page that is supposed to use the plupin, a window pops up saying I should install the ActivX controller. When I press ok another popup comes up saying that internet explorer needs to shut don because of an error. So it just shuts down. I have tried to go through the support pages and I cant see anything that would seem to help so there is anyone who knows how to fix this problem, I would appreciate it.
Thanks.

It's been years since I use Internet Explorer (especially on a PC).
You must "enable" the ActiveX control in IE. (Probably a preference setting).
Have you tried using other Web browsers? Most are free.

UDPATE:
Spoke with Express lane, and issue was escalated. Kudos to the support guys that handled this one (Brian and Yi). Went through everything in detail and took all the crash dumps off the iphones and ipads to send to engineering.
After backing up the contacts, the recommendation was to delete all contacts in iCloud. Doing that caused my iCloud to crash (in the browser), so more crash dumps were sent to apple.
Eventually got all contacts deleted, then did a resync. Looks like IOS devices are coming back to life and syncing again.
Also, Outlook iCloud connector has just been updated to ver 1.0.1 so i installed that on their recommendation.
BOTTOM LINE workaround:
1. Backup contacts
2. Delete contacts in iCloud
3. Delete accounts on IOS devices
4. Recreate accounts on IOS devices.
Hoping a real root cause can be found and real fix implemented. This has caused me to doubt the stability of iCloud, so i will procees with caution.

This just started happening.. I open Itunes and the little round rainbow loading indicator just goes on and doesnt stop.. My itunes wont function.. It gets stuck. Then i have to force quit.. I tried to shut down and restart. also reloaded the latest itune

This just started happening.. I open Itunes and the little round rainbow loading indicator just goes on and doesnt stop.. My itunes wont function.. It gets stuck. Then i have to force quit.. I tried to shut down and restart. also reloaded the latest itune 11.1.3 and it still gets stuck.
i use an external HD and thats fine.. all files are in there. But I have no idea why my itunes app is getting stuck.
Am I the only person this is happening to? What can I do to correct this problem?

Have you tried giving it a reset? Hold down the sleep and home keys for about 20 seconds. When you see the silver apple let go and let it reboot and see if htat helps.

My battery on my iPad mini isn't charging, the charging sign is on, but the battery just keeps going down.

My battery on my iPad mini isn't charging, the charging sign is on, but the battery just keeps going down.

Try:
- iOS: Not responding or does not turn on
- If not successful and you can't fully turn the iPod fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.
Since you did not say how long the battery lasts I am nut sure the battery is the problem.
