Wifi not re-connecting on startup, after exiting sleep mode, etc.

For a while we had this issue with our wireless network, but as you can see the issue was resolved using the fix mentioned.
Now, we have a new problem. Approximately once per day (or more), my iPhone, after waking it up, will not re-connect to the wireless. It'll ask me to connect to a network, my network will show up, but when I click on it, it either says "Unable to Connect to Network" or asks for the password, I put it in, and then it says "Unable to Connect". We experience this on all of our family's devices...iPod Touch, iPhones, laptops, PS3...everything. The only solution we have found is to unplug the router, after which everything works fine. It's sporadic, unpredictable, and really annoying.
I've tried to keep track of when it occurs, but it's nearly impossible. The only difference I notice is that when a lot of the family are gone (like on vacation), it doesn't happen. So I don't know if it's the fact that there's so much traffic on the router that it can't handle any more device connections, or if it's one specific device that is making it knock off the other device.
Any help would be greatly appreciated. Thanks!

Well it depends which router you are using.. and how many devices that you are trying to connect with the router..

OSX 10.9.1 macbook pro 13 retina - wifi does not reconnect automatically when waking up from sleep mode since I have a Bluetooth apple magicmouse

Hello,
My config is OSX 10.9.1 new macbook pro 13 retina (2014).
The wifi does not reconnect automatically when waking up from sleep mode since I have a Bluetooth apple magicmouse.
It was not the case before I bought the BT mouse.
Is this problem between Wifi and bluetooth coming from the OS?
Is there a fix already available or scheduled?
Thanks

OS X Lion: Fix for wireless not reconnecting when exiting sleep mode

http://www.tech-recipes.com/rx/18931/os-x-lion-fix-for-wireless-not-reconnecting -when-exiting-sleep-mode/

I have the same symptoms with a 2011 iMac and my Senheiser Bluetooth headphones.
10.7.3 did not correct this bug.
I'm also using MS Messenger and notification sounds are also buffered until the headphones are switched on.
I found other threads dealing with this bug :

I'm currently trying the tip given in the last discussion :
"Success - in the Audio Midi Setup (Applications/Utilities) I changed the output to 2ch - 32bit Float and all the audio works well."
My headphones already had this setting, but internal speakers had 2ch - 24bit... is it a possible explanation ? Time will tell ...

E550 will not come back after hibernation/sleeping mode

Thinkpad E550 will not come back after hibernation/sleeping mode. please help. I just bought this garbage laptop about 1 month ago. the big issue is the laptop will not come back after sleeping. I often run some calculation for some hours, the laptop always goes sleeping and wont come back. I had to power off the laptop and re-started it again. All of my calculation results were gone. Lenovo support is very bad, I already submitted a service ticket 2 weeks ago, but nobody contacted me. Lenovo laptops are garbage. I will not buy it anymore. Anyone can help? thanks a lot!

HI Clare,
In the Toshiba Power Management utility you should click on the 'advanced' tab and about half way down the resultant window you should see an option for the action to be taken when you close the lid of your SA30.
Make sure that this is set to 'hibernate'. Then go to the power save modes and click on the 'details' tab and then the 'Power Save Mode' tab and make sure that the 'Hibernate' option is set to 'never'.
With these settings your notebook should go into 'hibernate' when you close the lid but not at any other time.
Note that you can set the notebook to hibernate when running on battery when the bttery capacity reaches a pre-set value of your own choosing.
regards,

Problem with the "now playing"-function after timer sleep-mode

At first: sorry for my english.
I have the following problem with the Nano 6G: I set the timer of my iPod Nano to shut it down after a while of playing. When I turn it back on afterwards, the now-playing-button does not show the song that it played at last. Instead of that the nano is automatically set to shuffle mode which was not activated before and the now-playing-button will show any other song randomly.
This does not happen when I switch it to sleep-mode with the button on the top, only when the sleepmode ist activated by the timer.
Does anyone notice the same issue with his nano? How can I bring my nano to play the same song after the sleepmode, that it played before?

Hey Ipaqman, that strange behavior of the Nano 6G annoys me for exactly the same reason: audiobook in bed + sleeptimer = losing the place. As You say, the 5G works better with that and I also hope that Apple takes notice of that issue and will solve it.
Until that I got myself a "workaround". I create a new playlist on the device, with just the single audiobook in it, that is actually in use. This helps me finding back into it, as long as "now playing" will not work correctly with the sleeptimer.

YouView box does not re-connect to network after l...

My youview box does not re-connect to the network after the home hub has dropped out. The original message I put in regarding this was moved to the BT Infinity Speed/Connection Issues forum but I still think this is an issue here. Is connectivity still an issue with the youview box or am I facing a problem? I have to restart youview whenever there has been an issue. I'd like not to have to do that. It should realise (several hours after the hub has restarted) that the network is present and use it.

You should be able to just go into settings and redetect the network - try this before performing a full power off
Tried successfully. Don't know why I never tried it before. It's a lot easier than rebooting the box
Get used to doing it on a regular basis especially as the HH5 reboots at least every 30 days

Could not even connect to wireless after apple up date!

Just bought an apple tv, it loaded up fine and I signed in with my ID, connected it with my iPad and computer. Perfect. Next day could not even connect to my network. When I try to it says "there was a problem connecting to the network. Check your settings and try again. (-3906) Please help as I have spent all day resetting and fiddling around with it with no luck
And if it's not solid in 14 days I'm taking it back

No promises but a system Reset cures many ills and takes but a minute to perform:
Hold down the on/off switch and the Home button simultaneously until you see the Apple logo. Ignore the "Slide to power off" text if it appears.
A Reset does NOT delete apps, photos, movies, music or any other data. A Reset does NOT delete any settings for email, network access, etc.
Also, you might wish to download the 4.2 User Guide. Read the suggestions on page 170 with special emphasis on the Network Reset.

Ipod touch will not stay connected to network after trying to use scrabble

I had a new ipod touch and purchased the scrabble app from EA games. I could not log into facebook to load my games onto the app on my touch. The ipod would send me to my home page and disconnect me from the internet. Eventually my ipod would not connect to the network at all. I called Apple and they determined that the ipod was faulty and sent me a new one. Upon receiving the new ipod I downloaded and tried to use Scrabble again not thinking that the problem was the Scrabble app from the get go. Now again my ipod will not stay connected to the network. I have deleted the Scrabble app and reset my network settings and still nothing. It will occasionally connect but I cannot do anything with the ipod. However, it will work when plugged into my computer. I have contacted EA Games with the problem and they have "escalated my issue to their expert team", but I have yet to hear anything back from them. Anyone else having similar issues and know how to resolve this?

Does your Wifi drop when your iPad mini went into sleep mode after upgrading to iOS 7?

Dear iPad mini users, to those who have upgraded to iOS 7 like I did, do you experienced WiFi drop when your iPad is in sleeping mode? I noticed this problem only few days after upgrading my iOS. Initially I don't think there is such issue. After your iPad mini recover fom sleep mode, then it will automatically connect to WiFi again. My point is it no longer connected to WiFi in sleeping mode and so could not keep me up-to-date with my mail if I am on WiFi.
Do share your view and if there is a solution, do share with me please. I have tried almost all solutions available online but no no avail. At the moment, I am activating my 3G network so that when mail came in, my iPad will notify me even during its sleeping mode but this is getting expensive considering I am using the 3G 24 hours every day now.

I found an solution. Go to Settings/Mail, Contact, Calendar/Fetch new data and than enable Push and choose to fetch hourly or every 30 minutes. In this case your iPad will stay connected to wifi even when smart cover is closed. If you select Manualy than wifi connection will be terminated when in sleep mode.

Again getting black screen after Exiting Safe Mode in Windows 8 as suggested by hp

I'm again getting black screen after entering safe mode after upgrade to Windows and exiting from safe mode but after exiting my laptop display was of 8.b but after some time it again went back to same black screen problem .I disabled Intel and amd hd 86graphics driver in safe mode.please help .

Hi there ,
Thank you for visiting the HP Support Forums and Welcome! I have looked into the issue you are having with your display Turning Black after entering Safe Mode. I found a document for you called Troubleshooting Black Screen Displays with No Error Messages During Startup or Boot. It would be very helpful for me to know what has been done already so that I can narrow down what troubleshooting would be best for you. You mentioned in your post "again". Is it an intermittent issue? Please follow these provided troubleshooting steps, re-post with the results of the steps in the document, and any other troubleshooting steps you had tried and the results. Have a great day!

Bluetooth fails to connect to mouse after reboot/sleep

My bluetooth mouse (an Arc Touch) fails to get connected when my MacBook Pro starts up or comes out of sleep mode.
So I reset the mouse and "pair" it again, removing the previous entry for it, and the mouse works again.
If I then power off and restart, it fails and shows up as "not connected".
Have to "pair" it again, every time.
This was working fine until I upgraded to OS X 10.2.2.
I've reset the SCM and PRAM with zero success.
Any further things to try?

Ok Rb621,
Follow the same procedure as you have done before. Exception - At the restart, boot into Safe Mode. You don't have to log in. Wait a while, have something else to do. During this time, OS X will clear some caches. Come back and restart normally and see what happened.
Have fun

Firefox 14.0.1 tabs not responding after active sleep mode in the new OS X Mountain Lion.

Further to installing OS X 10.8 Mountain Lion, the tabs on Firefox become unresponsive if I try clicking on them further to my Macbook Pro going into energy saving (sleep) mode.

Search these forums. There are hundreds of posts for the same thing. There was apparently a bad batch of 330M cards that Apple used.
Also, you have no third-party extensions interfering. Therefore, it is more than likely a hardware problem and not a software problem.
And, this is a nice little clue:
Kernel Extensions in backtrace:

And, we just picked up my daughter's Mid 2010 15" MacBook Pro from the shop after having the same servicing done.

After resuming Sleep Mode WIFI Must Be turned off and on to work

I have an IPad 2, 64GB, WIFI 3G. EverytTime I resume Sleep mode, I have to restart WIFI to get a connection. It runs perfectly, until the next sleep mode resume. This is ennoying. Does somebody have an idea?

I saw a thread like this a few weeks ago but don't remember if they reached a solution. I'd do a search of the iPad forum and see what comes up and read through them.
Good luck.

WIFI slow to reconnect when phone awakes from sleep mode

Today, I updated my LG G3 to Android Lollipop. I have WIFI set to turn off when in sleep mode (unless device plugged in). Now when the phone comes out of sleep mode, it takes up to a minute before the WIFI connection is reestablished. With the previous version of the OS, WIFI reconnected immediately after awakening from sleep mode.
Has this problem been reported to Google? I have not found a way to report bugs directly to Google as a user.
Thanks,
Tim

Joel, thanks for your reply. I've followed your instructions, and the problem persists. I assume by reset, you mean reset to factory settings. No. It has been rebooted, and powered off/on several times since the OS update. I have no idea whether there are any apps that use WIFI only. How would I know what each app may require?
Since this happened immediately after the OS update, the logical conclusion is that the update caused this behavior. In my 45 years as a software engineer, I can say this is the most likely cause.
Now, here are two more observations. When I first power the LG G3 up, the WIFI connection is made immediately; before I even unlock the device. So, we know the OS is quick to establish connections upon power up. It is only when coming out of sleep mode that the WIFI connection is slow to be reestablished, taking about a minute as opposed to immediately with the prior OS version.
The second observation is that with my wife's Samsung Note 4, which was updated to lollipop several weeks ago, I do not see this delayed WIFI connection after being awakened from sleep mode. With the Note 4, the connection is reestablished immediately with lollipop as with the prior OS version.
Considering the difference in behavior between the Note 4 and the G3, I would conclude that LG made a firmware change for lollipop which is causing the delay, or LG didn't make a necessary firmware change for lollipop which is causing the delay. At this point, I would say this is an LG G3 problem. It should be easily reproduced. Under the advanced WIFI settings, the setting "Keep WI-FI on when screen is off" should be set to either "Only when plugged in" or "No".
Thanks again for your help.

Issues Exiting Sleep Mode and Odd Behavior On Restart with GPU

I'm running a completely stock HP P7-1240 desktop except for an EVGA GeForce GTX 750 TI SC GPU. The GPU runs fine when the computer is up and running (which is odd because the forums have several other threads mentioning that the 700 series should be incompatible with my BIOS).
However, there are two main strange problems that have arisen since installing the GPU. One is that, whenever the computer enters sleep mode, it refuses to wake back up properly. It seems to me that the computer activates but does not send any signals out from the back panel (at the very least, no video signal because my monitors stay blank). On a rare occasion, it will wake back up properly, but at least 90% of the time, it needs to be restarted. Upon restart, sometimes the same issue occurs (no video output), and the computer needs to be restarted a second time before it will boot up again.
This leads to the second problem. When starting, the computer goes to a black screen listing basic computer specs (see attached photo. At this screen, the computer does not respond to any input. It proceeds to beep 3 times, all the same length and pitch spaced about 30 seconds apart. After the third beep, the screen goes black and then the computer boots up normally with no further odd behavior.
Without the GPU, none of these issues happen. At the very least, not regularly.
I have seen another thread mentioning that, although the HP support page for my desktop does not list it, there is a BIOS update for my motherboard that has fixed issues relating to more modern GPU's. By nature of it being a BIOS update that does not (appear to) officially support Windows 7, I'm hesitant to move forward with that potential solution.
Although I'm planning to build myself a new computer from scratch at some point, I was hoping to at least get another year out of this machine, if not 2. While this issue doesn't appear to be immediately threatening the stability of the computer, I can't help but think that this is an issue I should iron soon to avoid future issues (not to mention it would save me a fair amount of electricity to be able to enter sleep mode on a regular basis).
Any suggestions would be greatly appreciated!
This question was solved.

Hello @johnmwalker,
I understand that you are having some issues with your HP Pavilion p7-1240 Desktop PC waking up from sleep mode. I am not sure how much can be done for the delay on your startup with an OEM BIOS you are limited in what you can do and since your graphic card works I think you would be better off not messing too much with the BIOS at this point. The one thing I would try is going into the BIOS using the HP Support document:BIOS Setup Utility Information and Menu Options, and under Advanced > Power-On Options set POST Messages to Disable and POST Delay (in seconds) to None.
Now the waking from sleep mode issue could just be the hybrid sleep setting causing you an issue with sleep mode. Use the following steps to disable hybrid sleep:
Step 1. Click Start
Step 2. Click Control Panel.
Step 3. Click System and Security
Step 4. Click Power Options
Step 5. Click High Performance from Power Options
Step 6. Click Change plan settings
Step 7. Select Change advanced power settings
Step 8. Click the plus (+) sign next to Sleep
Step 9. Click the plus (+) sign next to Allow hybrid sleep
Step 10. Select Off from the drop-down menu
Step 11. Click OK
Please re-post if you require additional support. Thank you for posting on the HP Forums. Have a great day!
