ICloud services stop working suddenly? Read if you use OpenDNS

Hi,
If your iCloud services like Find My Friends or Find My iPhone have stopped working on your devices recently while connected to your wifi network, and you get errors about not being connected to the Internet, and you use OpenDNS domain filtering services on your network, you might want to add icloud.com to your OpenDNS whitelist. It appears that they just added icloud.com to various blocking filters like chat, file storage, etc.
You'll know if OpenDNS is blocking your access if you use your desktop browser to go to iCloud.com and you get the OpenDNS block page. That's how I finally figured out what the problem was. I was going to try to log into iCloud from my browser to make sure my account was not hacked.
I wonder how many support calls Apple is getting because of this...
Anyway, I hope this helps others who might find themselves with icloud services not working suddenly on their devices.
Mike

Mike,
Thanks for your posting. I observed the same situation at my location and it seems that someone inserted the "icloud.com" domain in the "Instant Messaging" category as I block that one.
At the moment of writing these lines, the "icloud.com" domain is part of the following categories at OpenDNS:
Instant messaging
Chat
File storage
Webmail
Software/Technology
Some solutions will be for you to either whitelist the entire 'icloud.com" domain or allow the above mentionned categories.
Cheers

Data services stop working after updating to new OS version for Q10

I am from Qatar, after i updated my device ( Q10 SNQ100-3 ) to new OS ( 10.2.1.537 ), the mobile data services stopped working, but it works everytime I connect to wifi. This is the same with Z10. Please need help.

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 1 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!

@Keith:
Why are you always proposing your 'further questions' as answers? That's not adequate in any way!
Especially as a 'Moderator' you should know better, I really dislike this and I am quite sure that I am not on my own with this opinion.
http://social.technet.microsoft.com/wiki/contents/articles/4865.whether-or-not-you-should-self-propose-an-answer-in-an-msdn-or-technet-forum.aspx
It is pretty obvious from the post that this happens while loading WinPE, what is there to misinterpret?
Are you using different WDS servers for your sites?
If yes, try to remove the boot image from the 'Broken' one and re-import it.
Comparing checksums is never a bad idea in such a scenario.

NB520 - Wifi stopped working suddenly on its own

Hi,
I bought my NB520 in Singapore.
The WIFI was working properly for almost 3 years until recently I have this strange problem.
It stopped working suddenly on its own last June for almost 2 weeks.
Just when I was about to send it to the repair centre, it came back on again.
But the WIFI comes on and off for a few more weeks before it stabalised.
It works ok ever since, until 3 days ago it went off again like the last time.
Usually, when I switch on the netbook, the WIFI indicator (red light) will come on within seconds.
To use Bluetooth, I just right click on the Bluetooth icon and press "Enable Bluetooth Function" and Bluetooth will turn on.
But now when I do that, it tells me to "Plug in Bluetooth device".
Is this a hardware or software problem ?
I spoke with a local technician but she is unsure too.
Would appreciate if you can help me with this problem. Thanks in advance.
Regards,
Fionna

> Is this a hardware or software problem ?
This can be answered very easily recovering the notebook back to factory settings.
But I guess this is not an option for you at this time. Isnt it?
However, the issue you are talking in your post looks like the WLan isnt enabled and chosen properly.
Usually you can use the FN + F8 key combination to enable and disable the WLan and BT module.
Pressing both keys would switch between WLan and BT as well as disable and enable the modules.
Did you test this in the past?
In case the FN + F8 would not work as it should, I would recommend you to download the Wlan driver from Toshiba page released for this notebook series and to reinstall the Wlan driver.
Your feedback would be greatly appreciated.

Integrated microphone stopped working suddenly on my HP i-7 DV6! I tried everything!

Hi guys! Thanks to anyone seeing this. My laptop's integrated microphone stopped working suddenly. I have daily skype meetings and it worked perfectly fine but today it suddenly didn't work. I didn't make any significant changes before that.
I tried uninstalling and installing the drivers from the website but when I uninstalled, the new drivers said that a device is missing. I cannot paste the error message exactly how is written for you because it is in greek. but the translation is that a device part is missing or something.
after that I've done a system restore went back 4 days and I have now my drivers back but the microphone still isn't working.
I figured out that if i plug my apple headphones i can hear audio but it doesnt detect my recording. (i dont know if it's supposed to anyway!
Thanks in advance to anyone that might have a solution!
Windows 8
HP Pavilion DV6-2150EV
Product Number: VY101EA#B1A
Serial No.

Thank you for this. You are amazing for trying to help me. I kept on not being able to find the solution for 2 days and no voice application worked until yesterday evening. I logged into an online shop and bought a headset costing £10. As long as I entered my details and pressed PAY, my girlfriend called me on skype and voila, she could hear me. I think there might be something wrong with the insides of my laptop! Might be a significant amount of dust and dirt.
Thank you very much again. If this happens again I will read this post again carefully and get back to you.

Ethernet stopped working suddenly

I've been reading various topics on this board and it seems like many people have this problem but there are not many solutions.
My problem is that my ethernet stopped working suddenly. I've taken the following steps:
- reset the cable modem
- reset the router
- turned off my ethernet card and rebooted the computer then turned it on again; renew DHCP ip
- create a new location
Does anyone have any suggestions?

I'm not an expert, but here are a few suggestions & questions:
• Did you reset things in the order you wrote them in your post i.e. modem before router? (That can be important. Also I find it takes my modem a couple of minutes to establish a connection, so I wait for a while before I turn on the router.)
• Do you have any other computers wired up? Do they work?
• Have you tried setting the computer location to Automatic?
• Does your Modem have LED readouts which indicate when it is connected to the Internet and to a router?

Try Googling "sync without iTunes".
There are free alternatives and there are not so free alternatives.
Btw, to check if AVG is causing the problem, you should uninstall AVG and not just "turn it off".
Also, can you describe how you go about uninstalling a program? For example, how did you "delete" iTunes?

I own a HP Pavilion dv6915nr, it stopped working suddenly.

Hello,
HP Pavilion dv6915nr.
Windows Vista home premium 32-bit.
I own a HP Pavilion dv6915nr, it stopped working suddenly last night. It was working perfectly, I was watching a video on HULU and I stepped away for 2 or 3 minutes, when I came back the screen was off. The laptop seemed to be on sleep, but when I tried to use it again it didn't do anything. When I try to turn it on the keyboard lights turn on for about 2 seconds, then it goes completely off and there is a faint cracking sound on the speaker bar.
I already tried taking the batteries off and using the AC/DC adapter only, it did not work. When I plug-in the AC/DC adapter the light around the power connector turns on.
Hope someone could help me. Thanks.

Try a hard reset, works sometimes.Disconnect all external devices first.
1-remove power cord and battery
2-press power button for 30 seconds
3-reinstall only power cord for first startup.
4-power on
******Clicking the Thumbs-Up button is a way to say -Thanks!.******

I have the same bluetooth controller (0cf3:3005, Atheros AR3011) on my laptop (ASUS K53SV) and have the exact same problem. Bluetooth works for a while until tx errors start showing up:
[24952.326871] Bluetooth: hci0 command 0x0c1a tx timeout
[24954.332842] Bluetooth: hci0 command 0x0c52 tx timeout
[24956.338826] Bluetooth: hci0 command 0x0c24 tx timeout
[24958.344882] Bluetooth: hci0 command 0x0405 tx timeout
[24993.806536] Bluetooth: hci0 command 0x0408 tx timeout
[25033.899824] Bluetooth: hci0 command 0x0408 tx timeout
[25048.548327] Bluetooth: hci0 command 0x0c14 tx timeout
[25051.014213] Bluetooth: hci0 command 0x0c14 tx timeout
[25075.805968] Bluetooth: hci0 command 0x0408 tx timeout
Resetting the bluetooth device works sometimes but not always. There is always a chance that the device will just become unresponsive to any kinds of commands:
# hciconfig hci0 reset
Can't init device hci0: Connection timed out (110)
I've tried various methods (block/unblock them with rfkill, `rmmod btusb` & `modprobe btusb`, etc) but none works after the device is "dead". The only way to recover seems to be powering off the laptop (simply rebooting doesn't fix the problem).
