Wi-Fi stopped working about a week ago, workaround is available
Laptop HP ZBook 15
Wi-Fi stopped working, did not change any configuration when it happened around kernel upgrade 3.16.2-1 -> 3.16.3-1, ~ September 17 - 19
Going back to 3.16.2-1 did not help, also tried to downgrade other packages, such as linux-firmware, used "pacman -U" to downgrade
Found a similar https://bbs.archlinux.org/viewtopic.php?pid=1451445, but the exact https://wiki.archlinux.org/index.php/Ne … ice_failed did not help. After some troubleshooting, here is what I do each time to connect to a Wi-Fi (I have a script):
$ rfkill unblock all # More details are in the other log below
$ ifconfig wlo1 down
$ netctl start w # Now it will work
Unless there is a better one, this workaround can help the others, please consider amending https://wiki.archlinux.org/index.php/Ne … ice_failed
Also, if anyone is up for a solid fix, or a better workaround, here is a more detailed information, all commands are performed right after boot:

Hi,
Try Disabling it then re-Enabling it.
If that does not work remove the Apple ID by using the Sign Out button and then re add it.

I have been online banking with TD Bank for years now and have never had a problem getting into the log in. About a week ago when I would click on the log in button, nothing would happen however I can get into every other link on that site. I contacted TD Bank and they said that my account was fine and I was not locked out and there were no security issues. I then called Time Warner and they checked my service and said nothing was wrong with my service and that it sounded like it was from my server since I was going through Firefox, I should call you guys and see if it is the problem.

Until a couple of weeks ago I could clear my history under the "Tools" setting.
Now the only way I am able to clear history is to open the history, select all, and then delete---all manually.Dear cor-el:
I did restart in Safe Mode; however, I DID make change in the Safe Mode restart window, resetting to defaults.
Not only did this not help, but now it is worse, as my history won't show up when I click "Show All History" so I am unable to clear history even manually.
Did I misunderstand your suggestion? I've been using Firefox with various versions of OX 10 for years w/o such a problem, and now have so many bookmarks on Firefox that I hate to abandon the browser.
However, I do not wish to have a permanent, unclearable history.
Below is a screenshot of how the Safe Mode page appeared. -
Anyone having issues syncing iPhone 3GS with Microsoft Outlook 2007? iTunes says it is syncing but it will not update calendar or contacts. It just stopped working a few weeks ago.
I'm glad to hear that I'm not the only person struggling with exact issue. I've rebooted, upgraded, re-installed, pulled all my hair out as nothing works.
The biggest dissapointment with this thread is that nobody seems to have responded with a solution.
And yes I've managed to pull together enough intellegence to tick the box "sync to outlook" in iTunes - still nothing man.
Definately does not sync from phone to PC and is very hit and miss on PC to Phone. In other words now running 2 seperate calendars - Not helpful Jan. -
I just downloaded firefox about a week ago and the first day i used it i went on to tumblr, and i logged in just fine. But now a week later i'm trying to log into my tumblr and it says it's loading but then it goes straight back to the log in page. I contacted tumblr support and they said to check if i have cookies, and i do. i'm very dissappointed that firefox won't work with tumblr.
solution doesn't work for me. i think those firefox developers are either ignorant, incompetent or simply uninterested in solving this problem which has been around at least since 2010 - we're now in 2012.
i've been loyal to firefox for 10+ years but now i gonna switch to chrome, which i have been using in parallel for a while now and which has not given me any headaches. firefox usage worldwide has been in decline since 2011 and i think this trend reflects the disconnect between the developers and their user base since the chrome-like decision was taken to go down the fast upgrade lane. google can pull that off successfully, firefox can't - sadly. -
My backyard monsters and dragonvale apps both stopped working 2.5 weeks ago.
I have read forums from apple and the developer sites. I closed the games, turned off my ipad, deleted and redowloaded backyard monsters. None of it has worked. There has been 1 update for dragonvale and 2 for backyard monsters since they stopped working and those have installed no problem. The games both stopped working the day I updated the newest iOS version to my iPAD. What do I do now? Those are my two favourite games
Thanks for any helpDelete the files extensions.* (extensions.rdf, extensions.cache, extensions.ini, extensions.sqlite) and compatibility.ini in the Firefox [[Profiles|profile folder]] to reset the extensions registry. New files will be created when required.
See "Corrupt extension files": http://kb.mozillazine.org/Unable_to_install_themes_or_extensions
If you see disabled, not compatible, extensions in "Tools > Add-ons > Extensions" then click the "Find Updates" button (in Firefox 4: right-click the extension -> "Find Updates") to do a compatibility check. -
This is what message I get when trying to open on my Mac OS X 10.10 (The file “Record of Work Nov28-Dec11-2014.numbers” couldn’t be opened), which the same file that can be opened from my IOS 8.1 iPhone.
Seriously *** givesThe most likely reason you can't open this file is that you are using an old version of Numbers. It's easy to accidentally attempt to open your document with the previous version (V2).
In rare cases, the document can be corrupt and your only recourse is to grab a backup copy.

I've had a Samsung network extender for over a year and it's been great. About a week ago, my iPhone 5 stopped connecting to it. I've never had problems with this. All the lights on the extender are blue, so it seems it's working fine. Any suggestions?
Oh no! Lets ensure that you are connected. Have you tried to reset the Network Extender? Are other devices able to connect to the Extender? Is your Internet service up and running?
Share details so that we can help!
Thank you,

Time Capsule error 22 - My time capsule was working fine and didn't notice anything wrong with it until it stopped backing up about two weeks ago. I never changed anything like computer names or the Airport settings. All I get is the following:
The backup disk image "/Volumes/Data/Linda's Computer 1.sparsebundle" could not be created (error 22).
I tried resetting the Time Capsule and connecting with an ethernet cable, although the Ariport Utility says everything is working fine through WiFi.If the light will not turn on the TC is dead. No matter that the hard disk is running.. it should only run at start up or when it is accessed not constantly.. that means the board in the TC has failed. Apple do not repair them.. They will replace it under warranty or applecare.
If you have gone over the 12month warranty it will still be covered if you have applecare on any computer or an Apple TV. In fact the cost of the apple TV plus apple care is still cheaper than buying a new TC.. so it is a route some people are taking.. certainly depends.. in some places like Europe or Australia now, there is a recognition that statutory warranty must be longer on a product that is premium to the market. 12months is not good enough. Apple will sometimes listen.
They might be fixable but I do not know how. -
hi
Since about 2 weeks ago for no apparent reason, the internet on my iPad suddenly stopped working (when I open Safari, it says: "Safari cannot open the page because it is not connected to the Internet"), even though the Wifi icon in the top left corner still shows full signal. However, I noticed when I went into Wifi settings (Settings>Wifi) that there is no checkmark next to my network name (only the spinning circle icon, as if it's trying to process something). This only happens at home (I can browse the internet while connected to Wifi at university). My other Apple devices (MacBook Pro and iPhone 4S) work perfectly fine at home.
I've tried resetting my router, restarting my iPad, resetting Network Settings on my iPad, and tried following Hynes' instructions on this thread:https://discussions.apple.com/thread/2453187?start=15&tstart=0, but nothing has worked so far (although I have to admit that I found the instructions on that thread somewhat confusing, so there is a chance that I accidentally did not follow them properly).
Could someone please help? It'd be VERY much appreciated. -
I have a IPhone 4S and since about a week ago my wifi wouldn't let me slide it to the on side and my personal hotspot doesn'tI don't live in Quincy anymore:( but I'm game some weekend! work either. AND also I see a lot of other people with the same problem. And I PAY FOR IT EVERY MONTH . I'm going to stop paying if You can't help me thanks.
Is your wifi greeyd out; have you attempted to reboot the system?

My ipad mini is not being recognized by the new iTunes update that just came out about a week ago it worked fine till the update I have windows 8.1 does anyone know how to fix this problem and I just bought my ipad mini
I found this is another thread - same issue.
Re: iTunes has stopped working. Why?
Sep 11, 2013 6:07 AM (in response to thurdy)
Resolved!
After contacting Apple, I received a reply from their engineers:
Copy QTMovieWin.dll from: C:\Program Files (x86)\Common Files\Apple\Apple Application Support
to: C:\Program Files (x86)\iTunes
And that did the trick.

I've had my Mac and my Samsung for about 2 yeas now and I haven't had any problems with the two in regards to Bluetooth. As of about a week ago, I could no longer send files from my Mac to my Samsung. I don't know what has gone wrong, but the devices are still paired and I haven't changed any settings. I don't understand how it can just stop working
When I click the "send File to device" option, it doesn't freeze or give me any notice stating the devices are not connected, it just does nothing.I have the opposite problem. I cannot "browse device".
I have a Samsung Galaxy S3 mini which was working fabulously through Kies and Bluetooth (on Lion) until I upgraded to Mavericks about 3 weeks ago.
Now, when I go to Bluetooth and "Browse Device", the following happens:
The Mac will eventually find the phone, say "connected" then it will say "the device does not have the necessary services". This is despite the fact that both are discoverable and have been previously paired.
Bizzarely though, I can send a file from my Mac to my phone through the "send file" command. That works fine....
Is there something I am doing wrong or is this problem just symptomatic of the ongoing Apple-Samsung spat?
And yes, I know that Kies is now no longer supported by Mavericks and vice versa (boo!), so I have had to use other rather cranky solutions (Android File Transfer) and a faffy google calendar sync to sort the rest of the compatability problems out. The Bluetooth issue is just odd though.
If this is just an Apple-Samsung software war problem, I really wish both would grow up. Many people no longer care who made what first, we just want stuff that works. If iPhone contracts were cheaper, I would get one, but I refuse to pay more than £15 p/m for a mobile phone, sorry Apple. -
This is my Story...
About a week ago i was seddling into bed. I plugged my phone into my dock as usual, heard the vibrate telling that it was hooked up and charging properly. I went to bed, then woke up and went to grab my phone. I noticed it was only 94% the top right corner in the battery it didnt show the lightning bolt, which means its still charging. I never really thought anything of it at the time. by like 1:00 i looked at my phone, and it was already 50% I decided to plug my phone back into the charger. IT WOULDNT CONNECT!! i started to cry... what was i gunna do? that all my money spent on it! I tried my USB for my labtop, ive tried 2 different docks, and i also took it into Sasktel and they plugged it in to. After the day went by, my phone completly lost battery and... turned off!! thats when i started going into Sasktel etc. i was FREAKING out!!! (still am!)
All my phone will still do is when i press the power button it a picture of the red dead battery shows up, as well as a electricty cord sign, with an arrow to a lightning bolt. i know that means that it needs to be charged. Im so confused it still frashes and shows stuff on my phone.. so it cant be dead .. right? When i went to Sasktel, i got the worker to look at it. He shone a light in the bottom charging spot. he told me after like 5 minutes of looking in there that he can just barely see a super light pink olour on the "white" sticker. He told me it changes to red when it hits water, and moisture. but.... i nver got it wet. i just woke up with it like this. so, i sunno how that changed colour. im gunna call apple again tommorow and see what they say. i really hop someone can help me, i dont wanna loose all my pictures and contacts. i have some valueably stuff. 1,500 picture!!! :O sooo please! any idea is help, and i hope at least someone will try
So far, ive tried the trick where u hold the home and power button for 30 seconds. It showed the dead battery lightning bolt sign. And tried many different plugs. People say, that because its a little pink, its toast. i dont beleive that, cause, it worked alll day tell it finally died! no probablems at all. so i just need to get it backon again. ill tell you what apple says when i call. HELP
all i wish for is for you guys to try, and say what you know! anything is better! i will try EVERYTHING!If you've had it for less than a year, then it's still under warranty. Take it to an Apple store or an authorized service facility. See http://support.apple.com/kb/HT1434
