WiFi drops (DNS) when charger is connected

Hello

Whenever I plug my charger on my Macbook Air 11 '', my fair blocks Wifi. Not only on my macbook, but on everything. It's sort of something to the router. I have no idea what. I had my ISP mechanic come over a few times to check if it's something on their side, but it is not. I can not find similar problems on the net. And I've checked everything. All settings are good. But only when I plug in my MacBook charger, it messes with my router and all of a sudden he says "Resolving host" and the DNS is lost. Even tried using different open DNS addresses. Nothing helps.

The magsafe becomes openly warm? You can use this mac/systems/power on off button to see what voltage it is putting out. Should not be more 12500MV.  https://support.Apple.com/en-us/HT203207 you can also try a SMC reset.  https://support.Apple.com/en-us/HT201295

  • 55WL768G: photo drop-outs when it is connected to the Win 7 PC (HDMI)

    Hello!

    My Toshiba 55WL768G is connected to a Windows 7 PC via HDMI (4 HDMI on TV) cable.

    I experience intermittent dropouts of the image (screen goes black for 1-2 seconds, as if it was looking for entry) then the picture comes back.

    It happens randomly - I tried to replace the HDMI cable without success. I also tried different graphics cards in the PC: AMD and Nvidia. Problem persists.

    PC sends 1920 x 1080 p at 60 Hz.

    How to solve this problem? Thanks in advance.

  • Internet goes when you are connected to wifi

    Bought an iMac on eBay this week, works fine apart from a problem I encounter with internet stall, which really starts to get boring!

    It's an iMac, mid-2011, with OS X el Capitan 10.11.3 installed and put to update to the most recent update.

    The question...

    When you are connected to our home network (Sky Broadband) I get internet access for 5 minutes for an hour then stop him internet but the wifi is connected. At this point if I check all other computers/phones/tablets on the network that they are all still connected to the internet with absolutely no problem.

    The temporary solution...

    If I disable the wifi on my iMac and then back on again once it reconnects immediately and internet works fine still a time - until it stops!

    What I tried...

    Restart the mac repeatedly

    Restarted the router again

    In network settings, advanced on the mac, I renewed the DHCP lease (loads of times - note it always seems to come back with exactly the same ip address - I guess it's good?), updated the DNS (last post I read said to use 2.4.4.2 so am currently on that), tried to manually set the MTU to 1453, I deleted all the other networks stored outside my home network Too much.

    Does anyone have any suggestions please for all messages that have worked for them, or things that I could try?

    Thanks a lot for your help

    Joe

    Did you erase the internal drive and install OS X yourself? Did you run the hardware test? If this isn't the case, please do both.

  • When my Macbook connect to WIFI my normal PC to the internet cut

    First off sorry for my bad English, but as say the title "when my Macbook connect to WIFI my normal PC to cup of the internet.

    I was playing online games (WoW) on my normal PC I opened my macbook to work with her, and then I saw that I was disconnected from my game online so I test a few times and the problem is that whenever my macbook is connect to my Wifi my router send... my PC internet is disconnected (my PC is using cable connect to the router)

    Thanks in adv

    That would be a problem with the way you have the router or computers configured for wifi. It could be that they are all both use the same ip address. Usually, when configuring a router you begin by setting up a computer with cloning the mac address of the computer to the router and then the other set up. If you do not have a mac address on one of your computers, it's the problem.

  • Freezing of L650 - 1 k 5 satellite when the charger is connected

    Hello

    I just bought a Toshiba L650 - 1 k 5 in a store of Toshiba with no OS on it. I put on a Windows 7 Professional X 64 purchased, legal with all toshiba drivers necessary. It was a week ago.
    There are a few days that the laptop has begun to freeze for no reason but only when the charger is connected. It was freezing with no runnig software, all of a sudden, when I went to the control panel and device control a yellow triangle were shown, but when I clicked on the failure notice it did not show anything a few clicks later, it showed that something wrong with one of the PnP devices, but none has been mentioned. I installed sp1 and a couple of drivers from Toshiba Web site and the machine still keeps freezing with no reason, especially when the charger is plugged?

    What is going on? Should I put a x 32 windows 7 on or what?

    Thank you

    Tomo

    Hey Buddy,

    I don t think that the 64 bit version of Windows 7 is the problem: is IT s software/driver related hardware problem or problem, but it is not easy to say because your computer laptop wasn t equipped with operating system preinstalled so you can t test with the factory settings.

    What you can try is reinstalling Windows 7 new with all the drivers prétestées on official website of Toshiba. Then, make sure the Device Manager shows no yellow exclamation more and test again the situation as a whole.

    If the same error, it seems to be a hardware malfunction and an authorized service provider can help you get rid of this.

  • IPad no charging current when it is connected to the computer, said

    Original title: why ipad indicates no current when charging connectd to computer

    My iPad needs to be reloaded, but when connected to the PC with the cable apple, says iPad not charging. Someone knows why?

    This is quite normal.  Apple has designed the iPad to the only charges when it is connected to a charger taken approved or to a USB port of high amperage only found on Apple iMac and MacBook products.  If you connect it to a PC port or non - Apple USB it will not load.

  • Randomly, the screen is blank when the charger is connected; generally very well during the execution of a battery

    We have a Dell Inspiron 6400 laptop.  When the charger is connected the screen will become black suddenly, and you can't seem to get the screen goes again.  It does not seem to close completely because when I press the power button twice (or more?) it brings back me to the password screen.

    This only occurs when you run the battery, IE. not connected charger.  I bought a new charger thinking that was the problem, but the same thing with the new charger.

    My only thought is that it could be the battery but unwilling to spend £60 on a new if it does not solve the problem.  And also the battery OK charges when the laptop is not activated.

    Help needed please!  Thank you very much.

    Hi Tiffany - Sorry a very very late thank you for your help on this.

    I've been very busy and have therefore been put off watching it.  We have been surviving off the battery and when he runs out to paralyze the system / sleep mode and reload.  It became quite frustrating and that's why I've decided that I really need to fix this problem.

    As you the advised, I went just through the safe mode and the problem occurred again glancing at your advice it seems there must be a hardware problem.  I had originally bought a spare power outlet, and this does not work then maybe it's the battery.  As you suggested, maybe a qualified support store is the best solution now.

    Thank you once more!  I am very grateful.

  • When it is connected to the LAN, FF cannot find servers; no problem with the wi - fi

    26.0 Firefox running on a Windows 8.1 System. The thing I meet is this: I have no problem loading of pages and surfing when I am connected to my wi - fi network (I have a double function modem that wireless and LAN at the same time). However, whenever I plug the LAN cable, I get the error message that Firefox can't find the server. In this case if I disconnect the wireless at the same time. BUT, if I continually press the button [start] or simply tap the icon reload the page in the address bar, will eventually load, usually after a few failed attempts. However, the page loads usually only partially in a first time, apparently without advanced HTML formatting. But, after clicking on reload again one or two times, the page loads normally. Unknown, is that the behavior is not consistent - some pages of charge very well. But I can't for the life of understand me a boss.

    I've tried troubleshooting by disabling NoScript, but it doesn't seem to make a difference.  It's almost as if the wait time for a response from the server is so minimal when connected to LAN that the server has no chance of loading the first time.  Does that make any sense?  If so, how can I go about fixing the issue?
    

    Thanks for any help you can offer on this (for me, anyway) head-scratcher.

    Maybe another DNS server is used or there is still cached data.

    Have you tried a hard facing to bypass the cache to refresh all files?

    • Hold down the SHIFT key and click the Reload button
    • Press 'Ctrl + F5' or 'Ctrl + Shift + R' (Windows, Linux)
    • Press 'Command + shift + R' (Mac)

    You can also try to switch to work offline/off voltage after changing the network connection.

    If is also possible that your firewall treats the Wi - fi connection other than the connection to the local network.

  • Why the last OS update cost me gigabytes of data when you are connected directly to my computer and ISP via Itunes February 29, 2016

    Why the last OS update cost me gigabytes of data when you are connected directly to my computer and ISP via Itunes.  29 February 2016

    While it is connected to ITunes via my Dell system, I was informed of the latest OS update for my IPhone 6.  I decided that the direct connection to the internet would be the fastest way to download and install the software.  During the process I started to have some warning of our AT & T account that I approach the limit of our data plan, then in quick succession, only warnings, said I've reached the limit and then passed in the data, limit charges.  At the time it was done, I had accumulated more than 2 gigabytes of additional data charges.

    Until that point, I was very pleased with the device and confident in the ability to use Wifi and data.  Due to this incident, I became very suspicious of the camera and the huge potential for data overcharges. It is extremely disconcerting as it happened while it is directly connected to the internet using my computer at home.

    Please note that, in the episode my ISP and the computer is remained connected to the WEB with no sign of connectivity issues.

    Someone at - he had a similar experience and understand what went wrong?

    Thanks for your support,

    You have chosen the option of direct download, you have received a message of warning from AT & T about it yet.

  • Second laptop unable to connect; When trying to connect wirelessly, says connection is successful, but the Public unidentified network, no Internet.

    Hi all.

    I'm really sorry to post this question, I must have read 100 other threads on this topic, but none of the solutions seem to work for me.

    I have a home set wireless network in place, which may not have a lot of problems with it that I have a laptop W7 which has a perfect wireless connection, and also our TV connect when you want, as do our phones and Xbox.

    We bought a second hand Acer aspire laptop for our daughter. It is running Vista Edition family Basic. Even if she had the factory reset done on this, because we can connect to the router with an ethernet cable and it works very well, we managed to ensure that all updates of Windows etc are all complete.

    When trying to connect wirelessly, it says connection successful, but it is to a Public unidentified network, and there is no Internet. Also, even if it says Local access, we cannot connect to the router settings page is.

    I have uninstalled and reinstalled the built-in wireless adapter and updated the driver to do this, he says that he is as up-to-date as possible.

    I checked that DHCP is enabled, we tried dynamic and static IP addresses, we have disabled and re ipv6 enabled, we used the command prompt to reset winsock and stack ip, I looked into msconfig services for service # Id_String1.6844f930_1628_4223_b5cc_5bb94b879762 # Apple off but it isn't here.

    I have a real dislike for Norton / products McAfee and there is none of these on the laptop. We will install Comodo Internet Security, Eusing Registry Cleaner, Spybot S & D and Spyware Blaster as soon as the wireless is configured and that the Windows Firewall is disabled.

    We also have many turns of the spin off the coast and laptops, etc. and deactivation and activation of the adapter.

    It seems that all the usual solutions for the lack of connection are not the culprits this time.

  • Request to another DNS server if the connection fails with the current

    Hello

    I would like to ask whether there is an available addon or a feature hidden in Firefox, which allows him to activate try to use other DNS servers if a connection has failed to a server. Lets make an example, would be the best way to explain:

    1. I want to connect to Google.com
    2 Firefox / Windows prompts for the IP address of the DNS server
    3 Firefox attempts to connect to Google but fails (the site had long to answer, for example)
    4 Firefox will try another DNS server, that you entered in your Page of DNS IPv4

    Or Firefox already do this? Because sometimes it fails to connect to a server when you use a special DNS server. If I change the settings to another DNS server, it works.

    Thank you

    Please upgrade to version 20.
