El Capitan 10.11.2 disconnects from the network of Canon printer macbook pro after each use but with the same OS version iMac remains connected

How to prevent my Macbook Pro El Capitan 10.11.2 going to disconnect my network printer Canon?   My iMac running the same OS version don't unplug and behaves like any normal wireless connection.  I deleted the printer and added back, reset printing, etc. nothing works.  Given that the Mac is 6 "each other and 5 feet of printer during the last test, it must be something specific to the Macbook.  The Macbook identifies the printer after each reboot the printer as printer Canon right, but once the task is completed does not have the printer.  Everything is on the same wireless network. Computer Windows also recognizes the printer and it keeps alive after printing.

Please read this message before doing anything.

This procedure is a diagnostic test. It is unlikely to solve your problem. Don't be disappointed when you find that nothing has changed after you complete it.

The test is intended to determine if the problem is caused by a third-party software that loads automatically at startup or logon, by a device, by a police conflict or corruption of system files or some system caches.

Disconnect all devices wired except those required to test and remove all the expansion cards from secondary market, as appropriate. Start in safe mode and log on to the account of the problem.

Note: If FileVault is enabled in OS X 10.9 or an earlier version, or if a firmware password is defined, or if the boot volume is a software RAID, you can not do this. Ask for additional instructions.

Safe mode is much slower to boot and run as normal, with limited graphics performance, and some things work at all, including an audio output and a Wi - Fi connection on some models. The next normal boot can also be a bit slow.

The login screen is displayed even if you usually connect automatically. You need your password to log on. If you have forgotten the password, you will have to reset it before you begin.

Test in safe mode. Same problem?

After testing, restart as usual (not in safe mode) and make sure you always have the problem. View the results of the test.

  • Wireless router is disconnected from the PC (s) during the use of Firefox 37.0.1

    This problem occurred for the last 2 weeks whenever I use Firefox on each of the 2 PC's I use it every day. The problem may occur a few minutes after the start of Firefox, or it may be hours of continuous use before the connection is lost. It's okay if I'm in Firefox by itself or have the background applications running, but without a doubt requires Firefox runs before I see a problem.

    Configuration: WIN 8.1 and VISTA 64. the two latest updates.
    LAN: cable modem and Belkin wireless router; together with the latest firmware.
    Firefox v37.0.1 without add-ins or modules. Start page is 'empty '.

    Symptoms:
    Status bar Windows shows that I'm disconnected from the router.
    Router and the modem status LED shows that I am connected to the internet. Same thing for the VICTORY of the network status app. It shows no connection to router.

    The problem can be temporarily fixed by power cycling the router. Or, in the meantime just a random delay the connection may (or may not) be restored on its own.

    I also use a standalone PC application that streams the text given in short bursts and runs all day (no video or music... just short lines of text) with no problems until I launch Firefox in the background. Then he can go a few hours before the connection to the router is lost. I also often watch videos on my Tablet without the router problems. While typing in this issue on a PC I was disconnected from my router. I'm hoping to get some suggestions as to what to inspect or modify. Thank you!

    Fred, I had to leave the House early this morning and had no time to dig a cable long enough to reach my modem to try your suggestion. But, what I did was half of your suggestion. I pushed the reset bit recessed on the modem and left the House around 08:30 with Firefox running on both computers. Seven hours later everything is normal. No router disconnects and I gave a very good workout system.

    I have also now initial notice that connects to the web sites are faster.

    It is obviously a logical explanation for what was going on, but to an outside observer (), I see absolutely no logical link to the 'solution' for the rest of the universe. I won't lose sleep on. And I'm going to ask you more specifically when the next puzzle problem occurs! Thank you, Fred!

  • Why is that every time I open an application that my phone disconnects from the wifi

    Everytime I open an application that my phone disconnects from the wifi.

    Here's a tip for the user on the problems of Wi - Fi. Suggest from the top and bottom. Maybe one of them will help you.

    (1) perform a forced reboot: hold the Home and Sleep/Wake buttons simultaneously for about 15-20 seconds, until the Apple logo appears. Leave the device to reboot.

    (2) resetting the network settings: settings > general > reset > reset network settings. Join the network again.

    (3) reboot router/Modem: unplug power for 2 minutes and reconnect. Update the Firmware on the router (support Web site of the manufacturer for a new FW check). Also try different bands (2.4 GHz and 5 GHz) and different bandwidths (recommended for 2.4 to 20 MHz bandwidth).

    (4) change of Google DNS: settings > Wi - Fi > click the network, delete all the numbers under DNS and enter 8.8.8.8 or otherwise 8.8.4.4

    (5) disable the prioritization of device on the router if this feature is available. Also turn off all apps to VPN and retest the Wi - Fi.

    (6) determine if other wireless network devices work well (other iOS devices, Mac, PC).

    (7) try the device on another network, i.e., neighbors, the public coffee house, etc.

    (8) backup and restore the device using iTunes (ask for more details if you wish).

  • SOLUTION for your HP printer disconnect and/or constantly disconnecting from the network

    If you are having a problem printing, scanning or fax with any HP printer because of this be disconnected and constantly disconnecting from the network, here again is the fix!

    I thought that this all after several failed attempts with HP Support, my Internet access provider and various troubleshooting tasks including reinstall the HP software and more and more.  Well, through self teaching on internet and exhausting search for 6 months, I FINALLY thought to it.  OMG!  I'm a paramedic (not IT) and a little computer but far not an expert.  I have all of you here!  Nobody seems to have the answer, but I'm sure that I'm doing it to 97%.  Whatever it is, if it please answer and let me know that it worked for you!  :-)

    It doesn't matter if your printer is installed cable or wireless.  You don't reinstall your software, no recycling power of your printers or your router/Modem.  Your printer is unstable on the network and continues to log out or disconnect from the network it is NOT because the software is glitched, it isn't a firewall problem by saying, is not a router problem, is not a problem with your power cord, because most networks use a 'Beach' and IP addresses for security reasons This kind of "cycles" the IP addresses of the devices to reduce the risk of an attack.  A printer is not a threat, but the 'network' don't own human intelligence, so he does not know this.  Here are my step by step instructions on how to basically your printer address IP (static IP) instead of change back through a cycle so drop your printer on the network or disconnected.

    Funny, if you're someone who has had the elements in your print queue, they will not print, and you turn your printer off and on again and suddenly your print... well documents, join my club.  The reason it works is that when you turn on the printer, it starts with the same IP address before cycle.  If you are someone who is sitting there for a while and all of a sudden your printed documents without changing you something... it is because through the cycle of change of IP address, it hits your printers IP address and the network would allow him to print.  Not very funny, I know.  It took me forever to figure out why my printer would print sometimes, but not always.  Since I thought at this point, I can SCAN, PRINT, and use all the features of my HP software installed like HP, Photosmart Essentials Solution Center.

    On your printer, go to menu/Setup/network and press OK.  In the network menu, print a "network configuration page" so you can see the IP address and other settings of your printer.

    Now, back to the main menu on the screen of your printers.  Or you can go to your web browser and type the IP address using decimal numbers too and this will take you to the web page of your printers.  Choose: setup\network, then press OK.  Look for the IP settings and press OK. Choose "manual" instead of "automatic". Manually enter the IP address it as well as the default gateway that you can see the Network Setup page you printed earlier.  Note: If you manually set the IP Address of the printer, make sure that it is outside the range of your router's DHCP. Otherwise you might encounter a problem with IP addresses on your network duplicate. (If you don't know how to do this, write back and I'll explain).  Don't forget to click "save changes".  Now, restart your computer, and print just what you want.  :-)

    A trick I often use with DHCP network printers:
    In printers and faxes, right-click on the printer and select "Properties".  Click Add a new port.  Choose standard TCP/IP port configured for the host name of the printer. Read the host name of the network printer configuration sheet.

    Using my method means that you always connect to the printer even if its IP address changes (which can happen with the dynamic configuration). This does not jeopardize the security of your network.  It shows just your printer to stay put and stop traveling the highway of IP address.  :-)

    The DHCP range is the range of IP addresses that the router distributes automatically as devices to join the network.  The DHCP range is determined by the router and each brand has a range that is set at the factory (which can be changed by you).

    Default value for the DHCP of your D-link is 192.168.0.100 to 192.168.0.199.  Thus, outside the DHCP range est.2 a.99.200 a.254.

    Is a handy cheat sheet attached.

    You can change this interval by entering the router settings page - type the router's IP address in a browser, enter the login information and access the DHCP parameter area (varies depending on router, hunting around).

  • Tecra A2 crashes when you are disconnected from the internet

    We have a customer with a Tecra A2 provided by ourselves that, after 5 months without a problem from time to time, hangs when it is disconnected from the internet.
    Reboot the laptop and the internet can be found sometimes up to 20 times and then it blocks again when we disconnect from the internet IE. A Ref post causing VOIP problems were found and the software disabled and disconnected hardware. No difference. Running XP SP2, IE6, Kaspersky Anti Virus, Tiscali ISP ADSL, modem ADSL Tiscal (a new requested just in case). A lot of work to do and lose valuable time with customer problem.
    Thank you

    Hello

    It seems that a 3rd party software causes this very strange problem.
    You suggested that VOIP is causing the problem. Well, the problem is that Toshiba doesn't support any 3rd party software and applications.
    What I can suggest is to check the Event Viewer logs. You will find all the errors that appear on the OS. Double-click the error and you should see the description of Microsoft.
    Maybe you will find a solution.

  • Satellite A200 Win8 64bits - Atheros AR5006EX disconnects from the network at random

    First of all, sorry for my bad English.

    Hi, I installed W8 a few weeks ago and I have a problem with the WiFi. The adapter disconnects from the network at random. Not a protocol TCP/IP fail because I don't lose the connection to the internet, I lose the connection to the network for everyone.
    Simply disconnected from any wifi network.

    I have read that wifi chips Qualcomm have problems with drivers in W8. I tested many pilots and all do not work properly.

    Any help?

    The wifi card is: Qualcomm atheros AR5006EX and the laptop is: Toshiba satellite A200-1TP.

    Drivers I tested (and didn't work):

    http://drivers.Softpedia.com/get/network-card/Atheros/Atheros-AR5006EX-WLAN-driver-300119-for-Windows-8-x64.shtml

    Thank you!

    Do you have these problems with the operating system supported?
    I mean A200 is pretty old machine and certainly not supported for Win8, so it can be a problem with all of this, especially with the drivers.

    Let's see if someone else has the same machine and have the solution to this.

  • Current file to use when it is disconnected from the network wireless/wired - shared network drive

    Hello

    We have a problem where we receive a "file in use" message when you are disconnected from the network. To reproduce the problem, what we do is:

    (1) connect to the wired network wireless disabled with

    (2) create a test document

    (3) to enter text and save on network share

    (4) remove the network cable

    (5) add additional text

    (6) reconnect the network cable

    (7) try to save the file to the network share

    At the beginning by clicking the X is the new message you want to save. Click Yes and the message arrives until the next time you hit the Hit of X no. and he loses the last change.

    From here we then go up to the network share, open the file and it comes up with "file in use. Open read-only. File is opened by us (Administrator account), and there is NO temporary file in the shared folder.

    Tried so far:

    -Run net config server/autodisconnect:-1 for trying to stop it disconnect the share

    -Checked pane, pane preview and off 'display the description of the pop-up window for folder and desktop items '.

    -Windows Update

    We try to reproduce on wired connection, because it is easier to reproduce that disconnects wireless. Seems to have an impact on several operating systems. Share folder is shared on a Windows 2008 R2 x 64 machine.

    Is this a known problem or is there something that we can configure to try to prevent the locking file after logging out? Ideally, we want the decline to go unnoticed and provide uninterrupted service to the user, unless they are trying to save during the fall.

    Thanks in advance for comments :)

  • When you transfer files to the internet, the router disconnects from the internet, but the network remains in tact.

    I have a wireless router Belkin g with 1 Server 2003 cable and 2 xp machines and 1 machine vista wireless. My problem is when you transfer files to the internet, the router disconnects from the internet, but the network remains intact. I cannot remote in all computers, but not internet. Once I have restart the router, everything works fine. I was wondering if anyone else has had this problem and how to fix them.

    original title: problems with the router.

    I have no solution for you.  It seems more likely to me that it is a hardware problem - but if it was related to traffic, I would expect that the problem on the downloads more downloads.

    In addition to DSL reports, you could try to ask some of the forums that specialize in the updated firmware for wireless routers.  This is not to say that you need to install the modified firmware (although there may be good reasons to do so), but people who do usually firmware mods are much how the equipment works and what might be its potential failure modes.

    Is one of the best-known sites DD-WRT.com, but there is one list of other here: http://en.wikipedia.org/wiki/List_of_wireless_router_firmware_projects the firmware on these sites was originally designed to run on Modem Linksys WRT54G, but applies generally to Linux with chips Broadcom - based wireless routers and DD - WRT claims that its firmware takes care of some Belkin routers.  If your router is one of those on what DD - WRT will work, there will probably be someone in the forum there will have something for you.  See the list here: http://www.dd-wrt.com/site/support/router-database

  • This family member is able to make me become disconnected from the internet.

    Windows IP configuration
    Windows XP / Home Edition / 2002 Version / Service Pack 3

    A member of the family interferes with my computer and worse me. It's work! This family member is able to make me become disconnected from the internet.  I'm not sure how he does it, but I have a feeling that he is able to see my IP address and it blocks my IP address of the router. I'm not familiar with TCP/IP or DNS settings. Here are some of my settings, perhaps you can direct me in how to change a parameter, so it can stop.

    Windows IP configuration
    Host name...............................................
    Primary Dns suffix...
    Node Type................................................ Unknown
    The active IP routing... NO.
    Active proxy WINS... NO.
    DNS suffix search list...
    Ethernet wireless network connection card:
    The connection-specific DNS suffix.
    Description............................................................
    developments
    Physical address...
    Dhcp Enabled.................................................... Yes
    Autoconfiguration enabled... Yes
    IP Address..........................................................
    Subnet Mask......................................................
    Default gateway...
    DHCP Server......................................................
    DNS Servers......................................................
    ......................................................
    Whether by TCP/IP or DNS, I believe that the family member is accessing my computer. Is it possible to change these settings where the family member is not able to see my local IP address? I need to change the DNS server settings and change TCP/IP settings. Maybe I'm wrong and you can tell me what I should do to fix this problem. Thanks in advance for your answer.

    As already mentioned LEM that the rule on the router has an absolute rule that can and cannot access the internet or other network resources.  I suggest you lock your computer, turn off the server, Remote Service registry service and Remote Desktop and change the password on all administrator accounts.  Make sure that your firewall is enabled and have it block all inbound traffic local.  Then talk to the guy that controls the router and ask him to lock the router with a password, the only way to bypass the router, then will be by resetting it and the router administrator will know if everything else does.

    Having said that your problems are probably not caused by another Member of the family, it could be caused by flaky or failing hardware, bad cable, bad router, network card bad, if you really think that your problem is caused by a member of the family of your computer, then your question must be addressed and brought to a head in a "family meeting" rather than in a public forum on the internet.  There is not a lot of people read here can do to change the behavior of the members of your family.
