Wi - Fi pass drops after iMac sleep mode

Help, please. I had a lot of Wi - Fi problems after upgrade to Yosemite. I know that many others have had similar problems and the Genius bar was not able to find a solution. I get the same "I never heard of this problem before" and then run simple diagnostic tests. Here are some features:

-iMac 21.5 "2011 Office

-OS X Yosemite 10.10.5

-Have had problems with connectivity Wi - Fi based on the current version works, but the worst problems came with Yosemite

-iPad 2, Asus computer laptop and HP printer work fine. I tested the Modem and the router, they work well

The problem: after my iMac Sleep Mode wake up my network connection is interrupted. I have to physically click the Wi - Fi connection and wait it is the signal (it takes about 30 seconds). It is not a big problem, but it becomes very frustrating after what happens every time. I have other users in households who also have this problem and they are not very good with the iMacs.

Someone had this problem and was able to remedy?

Thank you in advance,

Scott

  • Sierra crash when after the "sleep mode"

    My MacBook Pro (13-inch, mid 2012) after update of the sierra accident when, after the "sleep mode".

    I try to reset the SMC sama NVRAM but always crash.

    suggest to solve?

    Thank you

    When you say 'crash', what do you mean?

    Probably something that runs in the background. Open the black Apple at the top left. Select system, then users and groups and login items Preferences. All deleted in this window.

    You can add applications and programs back to the points of connection with a window to see what is the origin of the crash.

    You can also start the computer start-up (hold down the SHIFT key when you start) which will make the computer start with no 3rd party apps. If that solves the problems, just disable the third-party applications and add back one by one until the problem occurs again.

  • ALL-IN-ONE PHOTOSMART HP 5510 WILL NOT PRINT AFTER GO 'SLEEP' MODE

    My printer model:

    HP PHOTOSMART ALL-IN-ONE 5510 B111A

    Problem:

    Printer goes into sleep mode. After 25-30 minutes breaks the connection between the PC and the printer wireless. Beacon wireless is the same fashionable "sleep" and I see that the printer is connected to my router and there is internet connection. HP Print and Scan doctor sees the printer, but I can't wake the printer unless I restart it.

    What I've tried so far:

    I tried all the solutions offered hp.com; Reinstall driver, updating the printer software, setting static IP on the printer, static DNS servers, using HP print and Scan doctor.

    I've seen people questioned on this issue before and there is no solution. I really need help from HP!

    After days of research, the problem was finally solved! I applied the following steps below. Some steps may be unnecessary, I didn't waste my time knowing who.

    1. find your PC's DNS servers by typing ipconfig/all in CMD.
    2. assign a static IP address outside your DHCP range. For my Linksys router him between 192.168.1.100 to 192.168.1.150. So I put my static IP address as 192.168.1.20.

    To do this, click the button on your printer wireless. This will show the IP address of your printer. This type of your browser. Go/network/network address. Choose manual IP and write 192.168.1.20

    3 now come to section of the manual DNS server, and then type your DNS servers, you found before.

    4. open your HP printer program that must be installed with your driver. Utilities hit and update the IP address. Update your address with your static IP address.

    5. now go to your router settings. Find the wireless settings and change your not automatic standard 20 MHz radio band.

    6. change your standard channel to 6.

    7 find the wireless security and replace your WPA-personal security mode.

    8 disable UPnP

    9. This is the part of the KEY. Change the renewal of your key to 36000 seconds. (10 hours)

    10 go to the Windows Advanced Firewall. Enable all the disabled printer and share, entrants and outbond rules.
    I believe that the most important parts are affecting a static IP address outside your DHCP-range and change the key renewal time. I hope this works for you too

  • U3.0 dynadock not resumed after the laptop sleep mode

    Hi all

    I am confronted with the problem that my Dynadock U3.0 does not resume if I fashion "sleep" on my cell Samsun.

    It works very well at the start, it works when I take a full stop, and I just checked it in Hibernate mode and it seems to work fine too.

    Can anyone help me please with this problem.

    _Other factors: _
    I'm running it on a USB 3.0 connection.
    I have this USB connection should remain in charge mode 'sleep'.
    Windows 7
    64 bit
    dynadock model: PA3927A-1PRP

    The only way to get after that 'sleep' mode call is to pull the power cord out the dynadock, wait, then reinsert it.

    Any advice would be welcome.

    Thank you for your help

    Hello

    I think that it s not Dynadock question but with the USB ports on your computer/laptop.

    The sleep or Hibernate mode affects devices attached to the Dynadock and not directly the Dynadock. If the computer/laptop wakes up fashion 'sleep', the Dynadock should be recognized automatically. In the case where the device does not recognize the Dynadock, there must be something wrong with the computer.

    By the way: you said the Dynadock is connected to USB 3.0.
    I recommend to go to a USB 2.0 port and test it again.

    Last but not least: make sure Dynadock uses the latest display driver that you can download from this page: http://www.displaylink.com/support/downloads.php

  • End of 2015 iMac 27 inches 5K screen lights up when the "sleep mode"

    When the iMac is in "standby", sometimes the display lights for a while and then turns back off the coast. Screen does not completely, simply turn the backlight (it's like when you see a black image with the high brightness level).

  • Portege R830-10R: No. USB connection after recovery from sleep mode

    Nice day!

    I have experienced the problem depending on my Portege R830-10R for a long time.

    Quite often, when he recovers as soon as "sleep" mode it loses the ability to recognize USB devices and built-in 3G modem does not work as well.

    After awhile, like 10-15 minutes of work (or), the problem is solved by itself, but normally, it is not the case.

    If I try to send the laptop to Hibernate or "standby mode" again, while this problem is active, allows to say, it not put into hibernation and crashes on a midway with a black screen - so I have to stop it manually, and then start again.

    Normally, the only way to solve the problem is to restart, but the issue comes after the next "standby".

    Someone has something like this? Any solution available?

    Hello

    > Quite frequently, when he recovers as soon as "sleep" mode it loses the ability to recognize USB devices and built-in 3G modem does not work as well.

    Have you noticed this behavior from the first day of purchase?

    Only special USB devices assigned as USB flash memory stick or USB HDD or are

  • Satellite M40-110: WLan is not working properly after sleep mode

    Hello, I have a M40-110. I have some problems with my wireless adapter. After I closed the screen (bed) and the computer goes into sleep mode, I open the computer screen becomes active, but this time the wireless adapter is not working properly and I can't connect to Internet with my wireless adapter. Sometimes, it seems that the wireless adapter has established a connection, but I can't send and receive data from the Internet. Sometimes after this case, the wireless adapter becomes invalid.

    My Service offered to enable the bios wake-up-on-lan option. After doing this, the Internet worked properly.
    But I am wary about this option:

    (1) not allowing this option cause draining my battery quickly?
    (2) this option doesn't make that hides my hardware failure (wireless card) and it is really necessary to solve this problem?
