Connection problem Internet accounts

Hello, I am currently using MBP 13' early 2015.

After that I updated OS X 10.11.4 to 10.11.5, many problems has produced, including chrome and safari closed the problem that often needs force to restart the mac.

Today I "noticed" my calendar a major problem. It was linked to my google account and cannot sync more. So I got out my google account in preferences and tried to re-login. Even if I tried more than 30 times, I can't log in to my account. The situation is exactly the same in fowllowing link:http://apple.stackexchange.com/questions/218098/cant-add-google-account-to-osx

I tried a few prescriptions: delete some files (related to the google account) in the keychain, try to connect in safe mode, restart the mac, etc. Nothing has been useful.

After 3 hours, I also found other accounts have the same problem: once I log in, I can't log in again. More google reader shows another problem-sometimes I can not connect and it disconnected after the mac is restarted.

I think that my macbook has a problem on his ring or accounts on the Internet but I have no idea how to solve this problem.

Is there someone who has the same problem? Any solution?

If you have enabled the validation in 2 steps, you must generate a password specific to the application in your Google account and enter instead of the password for the login that you use on the Web site.

  • Connection problems Hotmail account on Satellite A305-S6909

    I experienced a problem connecting to Hotmail using IE8 on my Toshiba laptop. I posted this problem for Windows Live and my anti-virus. The two parties have not solved the problem after 2 months. The issue started around November 20, 2009. I think it may be related to a security upgrade or CrashFree upgrade.

    Information on the basis of the problem:

    When you sign in on Hotmail on IE8, I firstly have a message that my password is incorrect. If I try to log in again, I get the login screen (no message). If I choose the enhanced security Option, my browser allows to browse several blank screens before expiring. The site of hotmail then sends a message that the site is down, etc. Also, I can connect in the rest of the Windows Live, including MSN.com. When I connect to MSN.com, I can see the sidebar that shows the last 5 emails on my hotmail account. I just can't access these emails. I have no problem with any other website.

    Where this problem does not -

    1. this problem does not exist when you use FireFox.
    2. in Safe Mode with networking, this problem does not occur on IE8.

    Attempts at a solution-

    1. I worked with my anti-virus software tech support to confirm that hotmail is not blocked by the firewall. I have confirmed that it is not a virus affecting the program.
    2. with the Windows Live team, I went through the entire process of clearing cache, flushing the dns, restoration... I reloaded even IE8 on my system.
    3 Windows Live suggested that I use Fiddler Cap in order to acquire more information. This program generates an error when I try to run it. However, it works when I run it in Mode without failure.

    Laptop: Toshiba Satellite A305-S6909
    OS: Vista 64-bit
    Browser: Internet Explorer 8 (32-bit)

    Hello

    I don t use Hotmail but it is really strange. In my opinion, it has something to do with the settings of Internet Explorer, because everything does work with Firefox. Theoretically, this means that nothing is blocking your connection and AntiVirus/firewall doesn't block these connections in Hotmail.

    In the Internet Explorer options, you have different areas, like trusted sites, restricted sites, etc.. In your case, I would like to add MSN page you need to trusted sites.
    In addition block you / allow Cookies of some Web pages. Make sure that Cookies are not blocked.

    All that s what I can tell and the time and I hope that I could help you! :)

  • WRT1900ac internet connectivity problem, internet white flashing light!

    So my wrt1900ac has been flashing white tonight. I logged into the router, and do you have a router reboot. That did not work, then I rebooted my modem still does not work.

    After all that I did a factory delivered to my wrt1900ac which was a big mistake because now my wrt1900ac THAT WILL NOT back upward. He remains stuck on the detection of internet.

    So I did a factory reset my modem which is c1000a and after resetting my modem works fine connected to the wifi without problem what so ever. I handed my modem tried to re-setup my router and transparent bridge mode. Once more the internet wrt1900ac light just flashes white and not connecting, even if my modem works perfectly fine, can anyone help me please?

    Sorry, I'm such a newbie to metworking. I take a Cisco class at my local community college. I have no ideal just like the static IPS of default gateways. Now, I know I put my router for a PPPOE connection with my ISP provided connection information. And when I did a factory reset, I continued stuck in the 1st stage of the installation. I know that it does not help anyone to help me. But if someone could give me a few steps on exactly what to check before considering again to exchange it.

  • connection problem internet wrt1900ac

    Hello

    I'm having a real problem of base; probably missing something easy, but I can't the wrt1900ac to connect to the internet.

    This is my situation.

    WORK SITUATION: Cable Modem connection to the PC via cable yellow or orange or blue.  Set PC to DHCP.  No problem.  wrt1900ac NOT in question.

    Does not WORK: ADD wrt1900ac to the situation: disconnect the cable from the computer, turn off the modem for 5 minutes, then plug the cable/modem wrt1900ac.  Turn on wrt1900ac.  Internet light will blink orange and orange flashing white, then blinks, then flashing orange white, then solid.  IN CASE OF FAILURE.

    I don't understand how this could be true, unless there is something wrong with the wrt1900ac.

    What Miss me?  Why the wrt1900ac does not connect to the internet?

    I was on the phone today with high Linksys support for more than 2 hours.

    So here's the bottom line, maybe you will not have to suffer as I did.

    Step 1: Update the firmware.  In my case, I went to all that 1.1.7.160.177.

    Step 2: Under the connectivity > Internet settings, select "Clone MAC address".

    Step 3: Click on 'Clone MAC from my PC'.

    Step 4: Click on 'apply '.

    Fact.  Problem solved.

    PS - My ISP is Cox Communications.

  • Why do I get "Connection problem" on my laptop, when I try to access my e-mail account Yahoo with the new version of Firefox?

    Since I updated firefox to 29.0.1 on my desktop, I can't access my account at Yahoo.com from my ASUS laptop. "Connection problem" appears when he tries to retrieve new messages. I received mail on the ASUS 12/03/13, but from now on I get this message and no new mail arrives at the ASUS.

    Some problems occurs when your Internet security program was set to trust to the
    a previous version of Firefox, but no longer recognizes your updated as version
    level of confidence. Now how do I solve the problem: to allow Firefox to connect to the Internet
    Once again:

    • Make sure your Internet security software is up-to-date (for example, you are using the latest version)
    • Delete Firefox to list your program of trusted or recognized programs, then add it again. For detailed instructions, see Configure the firewall so that Firefox can access the Internet.
  • When I connect my hotmail account, I can't open any folder, the Inbox, the new message,... everything seems normal, but when I click on something, it isn't responding.and it doesn't see the error.it works very well in internet explore.

    When I connect my hotmail account, I can't open any folder, the Inbox, the new message...
    everything seems normal, but when I click on something, it isn't responding.it works very well in internet explore.

    I think the next thing to test would that interfere with Add-ons. Disables the Firefox Add-on - Add-ons that only list compatibility with Firefox 5, but some add-ons could cause problems.

    To test, the simplest method is to restart Firefox Safe mode.

    First of all, I recommend you backup your Firefox settings in case something goes wrong. See your backup information. (You can copy your profile folder Firefox together somewhere outside the Mozilla folder).

    Then, try help > restart with disabled modules > continue in Mode safe (do not check the boxes). This article gives more information on the options and features of Safe Mode: Safe Mode.

    What is fix? If so, you may have to disable some add-ons.

  • Problem with my Treo Windows Mobile 6.1 800w (Sprint) always connect to internet via Power Vision data services?

    I don't know if it's a good 'problem' or not (I don't see anything during my brief search), but Im wondering if anyone else has the same problems.

    I really like this phone compared to my previous 755 p, but I have two gripes in this regard.  First of all, there is no light that flashes when an alert or notification has taken place, or a call came, etc., as had the 755 p.  Why would this feature removed?  If the screen of the phone is off and vibrate (like how my phone is at work), you'd never know unless you have checked the phone or had put on alert constantly rehearsing and vibrate my office all day.  I can live with, I guess, but an update or application that could resolve this would be great.

    The real problem I have is with the phone always tries to connect to Sprint Power Vision Data services via #777 to synchronize my email accounts.  I have all the e-mail settings (Outlook and Gmail Pop) to manually check for new messages, and the UNCHECKED check box to enable the internet connection.  But every few minutes, or if a message appears asking to connect to the internet even if everything is set to manual.  It is so ANNOYING so now I just put it to stay connected.  The real problem is that it seems to be to kill the battery even more fast because its connected throughout the day.  Im trying to minimize consumption to save the battery life (turn down the backlight, disabled WiFi, screen turn off immediately when done using the TI, etc.), but I'm close to the point to get rid of the phone if I can't understand it.  Its a new phone and battery (Christmas gift) and I think that the battery should last more than a full day even with the light for no use.  I don't use the phone that much but it honestly be dead from 22:00 with only plain text messages and phone will use during the day.  I have probably of less than 200 minutes per month.

    I contacted the Palm support and worked with someone for a while, and it doesn't seem to be sure if it was supposed to be like that or if there was a problem.  In the end we left it as it was and he said I need to contact Sprint to see if they have something in their automatic configuration that makes the phone connect ALL THE TIME.  I still have to communicate with them, and I'd like to hear what others have to say.

    Don't make me get an iPhone lol.

    Thank you

    Well, I guess I figured out how to stop it from asking me to connect to the internet EVDO service every few minutes.

    It seems he was trying to do because of my two Pop email accounts I have set up.   On the enamel of the Options screen, it lists the e-mail accounts and there is an asterisk next to one of them.  If I leave the asterisk next to "Outlook E-mail" then it seems not repeatedly, try to connect to internet EVDO.  If I leave the asterisk next to one of Pop email accounts, he seems to want to connect to EVDO repeatedly.  I guess that the asterisk indicates the default or the main e-mail account of something, then he tried to update via internet services.  I guess that Outlook is configured to only update when a synchronization is performed, or something.  so if I browse the web with IE, I just manually disconnect after the browsing session and it is more requested to connect to EVDO when the asterisk is next to "Outlook email" in the list of accounts on the Options screen.

    Note, with some other applications and tweaks installed that I found on the forums, my battery life is now acceptable even with normal use.  still has 30% left before going to bed each night.

    Message is about: Treo 800w (Sprint)

  • Strange internet connectivity problem

    Hello!

    I'm having a connectivity problem I have never met before. I use a wireless router from Apple with internet cable.

    Yesterday, my computer would be is no longer in contact with my router wi - fi. I get a message that the network could not be attached (I ran the Diagnostics wireless, but it's a whole lot of sense to me empty files). However, I also have a Roku, and which IS connected to the WiFi without problem. I completely stopped and restarted the computer, no joy. Reset the modem and the router, no joy. Still works with Roku, not with the computer. But the weird part is, I have Optimum Online, which allows subscribers to log-in to its hotspots, and it worked! I am connected Optimum wi - fi network on my computer right now.

    So I don't know where is the problem! It is not the router, because this is related work with Roku and is not the computer, because it is connected and working with the Optimum hotspot. What gives?

    Try this!

    Go to the Apple menu > System Preferences > network

    Select a Wi - Fi connection in the sidebar and then click on the button "Advanced...". "in the lower right corner of the screen

    In the list of preferred networks, delete the name of your Wi - Fi network

    Click on the "OK" button to save that change and then 'apply' in the network preferences window.

    Now, go to the Applications folder > utilities > Keychain Access

    Make sure that "Login" keychain is selected and "All items" in the category is selected in the sidebar

    Use the search field to find items that Keychain with the name of your Wi - Fi network and remove

    Quit Keychain Access

    Now try and access your Wi - Fi network
