Internet MacBook becomes very slow

THE PROBLEM

A week ago from the internet on my Macbook has become very slow. Web sites load then, but it may take up to five minutes on some occasions, or even longer. This happens systematically 10 seconds to 5 minutes after the connection to the web. At first everything is super fast, then all pages/apps using the internet starts to turn.

ATTEMPTED SOLUTIONS

  • Replaced the modem & router: I bought a new modem-router combo to replace my original separate modem and router, no change in question.
  • Tried a third modem/router: a friend gave me his modem router to try and the same issue. (In both cases I had my ISP to update the MAC address)
  • Tried other devices: I tried the connectivity to other devices (iphone & ipad) and found no problem. Speedtest app appears 32mbps to the low and 5 Mbps + constantly.
  • Tried another browser: was using firefox, I tried Chrome - same question. In addition, any application on my computer using the web runs slowly, no browsers only.
  • Tried to connect to the Internet through direct ethernet modem: no improvement
  • Tried to restart the computer and the modem/router: it is 7 + times for two days with no change
  • Tried to connect to the web via a mobile hotspot on my phone: problem persists.
  • Updated my computer and all applications: no change
  • I started in safeboot and the problem disappeared

  • Firefox has become very slow. It takes a lot of time to load any website. I reinstalled FF but the fleeting problem.

    Firefox has become very slow. It takes a lot of time to load any website. I reinstalled FF but the rest of the problem.
    As a test, I downloaded Chrome and it is much faster.
    But I love FF and would be very happy if you can help me solve this problem.

    Hi Reos,

    When you reinstall Firefox it always uses your old profile with all the old things that you had. That said, you're lucky, there is a new feature that lets you "Reset" of Firefox. This will remove some of the pieces that might cause problems while it keeps your bookmarks and other important things safe.

  • Satellite A660 - Internet connection is very slow

    Hello

    I have a Toshiba Satellite A660-guest 1GT, bought the Poland and I have a problem with the internet. Where I live there is a wireless router and my laptop connects to the wireless but the internet works very slowly. I have a older laptop which I use in parallel on which the internet is much faster. When I clicked on the network and diagnose the problem, there was a message that the connection seems to be broken. In addition, the number of packages I'm sending is twice or three times less than the package I receive.

    I took out the battery, reconfigure power settings, reinstalled both drivers for the LAN and wireless, all uninstalled programs of eternal but the internet is still very slow. I have to wait more than 10 minutes to load a video on youtube. Which, on my old computer, it must be about 1 min. can you please advise me what to do?

    P.S. I donno if that counts. I got Windows 7 in Polish and I installed an English pack with vistalizator,

    Thank you!

    Hey,.

    Is Internet connection too slow when you connect the Ethernet cable? So, you can determine whether the problem is related to the Internet itself router or WLAN connectivity.

    Generally speaking, it is difficult to say something about the WIFI configuration and router. In your case I also get in touch with your internet service provider and ask for the correct router configuration. They can also tell you how to set up the laptop to go online. :)

  • HP DV3 become very slow where implementation failure

    HP DV3-2105ee

    Windows 7 ultimate 32 bit.

    Since I bought this laptop new each time failed when his laptop battery performance becomes very slow start of braking, power option is to select "Balanced" if I select 'Power saver' he not become slow when running on battery power, but often it becomes slow with any program running.

    In my country Bangladesh there are break after every hour of power.

    How can I solve this problem?

    This sounds like it may be related to a power management.  Looks like it's to reduce the performance of the material to save batteries.  This is a normal behavior with laptops, but it can become a nuisance if someone does not create a power plan that does not take account of this.

    Go to start, search for food options and open this result.

    Click on Show additional plans.  There should be a plan for high performance.  This plan will be favourable performance during the conservation of battery, so your battery charge may not last as long.

    Activate the power plan.

    The problem is still happening?

  • WiFi constantly fall, becomes very slow or can not find the network

    You just bought a new Sony Vaio with Windows 8 and the wifi keeps deleting, becomes extremely slow or can't find my home network. I know that it is not the router because my other two laptops work fine and have full wifi signal (1 running Windows 7, the other is Windows Vista). I tried using the troubleshooting and it cannot solve the problem (if it is said) and claims that my ethernet cable or cable router is not connected (does not solve anything because my problem is wifi, not on the cable).

    Perform a search on Google, it seems that it is a major problem with Windows 8.  Anyone have any ideas on how to solve this problem, before returning the laptop? (the question of the internet makes the laptop almost unusable because most of my things are on the cloud)

  • Typing becomes very slow in Firefox 3.6.11 in Mode safe mode with all extensions and plugins disabled.

    When I first start Firefox, all right. And everything is fine as long as I type in the text boxes on any web page. I can type in the address bar or search throughout the day with no problems.

    But, for example, just by typing in the edit box to ask this question on this site will result in the problem after I typed more say 150 characters. After this strike ANYWHERE in Firefox will be very slow, even the address bar or the search bar. It doesn't seem to matter what site use to type in the text. Cause the problem to occur after typing in enough strikes.

    Navigation & mouse clicking remains fast - it is only typing seems to be affected. In order to recover, I have to restart Firefox.

    If I look at the use of the UC Firefox.exe in Process Explorer, I see that once the problem occurs, the CPU usage starts whenever I type a key fortification. Indeed Firefox maxes one of my two hearts so the cpu is at 50%! He goes down to 0% again once I stop typing.

    As mentioned in the subject, it is in Mode safe mode with all extensions & plugins disabled. I'm running on Windows XP SP3 with an old AMD Athlon 64 X 2 Dual Core Processor 3800 + (1.81 Ghz) with 2.00 GB of RAM.

    I think it started to happen with Firefox 3.6 significantly (it's amazing how much time I can navigate without having to type), but it sometimes occurred with previous versions. Now he is annoyingly repeatable.

    I have to use '-no - Pei ForTyping distance "to start a separate session of Firefox that I use just to type in the text boxes, so I can restart at will. I also compose messages in an external editor and simply paste in Firefox to avoid typing as much as possible.

    This may be a problem with session restore. Firefox stores session data every 10 seconds to make it possible to restore a session crashed.

    It may be a problem with the sessionstore.js file in the profile folder

    Delete the sessionstore.js and sessionstore.bak and all files files sessionstore-# .js with a number in the left part of the name as sessionstore - 1.js.

  • I downloaded 8.1 on my iPad a few months ago and it has become very slow especially in the e-mail program and glitch

    I have an iPad mini version 9.02. a few months ago, I downloaded the latest operating system from Apple 8.1 and my iPad became very slow and glitchy especially in the e-mail software... What can I do?  Now it asks me to upgrade to iOS 9.1 and I fear that it will be even worse.

    Sorry - but what do you mean you have an iPad Mini version 9.02? What are your reference when citing 9.02?

    At this point, your best bet is to keep the device up to date. The latest version of iOS is 9.2. It's what you could be upgraded to.

  • Microsoft Update maintains the search forever and pc becomes very slow

    Hi all

    Last week did a cleaning installation (windows 7) on my old laptop.

    (the material is not good enough for an update for windows 10)

    At the beginning everything was fine and some updates have been installed.

    However, after the installation of "Windows 7 Service Pack 1 for x 64 systems (KB976932)" the trial was kept updated search forever and the laptop became also very slow.

    While windows searches for updates, the process "svchost.exe" develops very quickly in the memory usage and fills after a few minutes the total RAM.

    I tried various corrections (see for example the you link below), but none of the solutions worked for me: (.)

    http://superuser.com/questions/951960/Windows-7-SP1-Windows-Update-stuck-checking-for-updates

    For now I have disabled the update, but this isn't a permanent solution.

    I hope that any body could help me solve this problem.

    Thanks in advance!

    P.S. I also added a picture of the history of the update below.

    In addition, the laptop is an acer aspire 7715

  • HP BAC application VM Image becomes very slow to ESX backup starts

    Dear all,

    I have HP BAC/Sitescope application running on the Image of the virtual machine that is very slow on Fridays, while troubleshooting and usage I thought this ESX backup running during this period.

    Any Solution for this?

    Kind regards

    Slow is a very relative term.  With respect to the use of resources, if you are running in contention for resources, you can always increase actions/rights for this virtual machine.  This could be memory, cpu, disk related to resources that are on sale.  You need to understand who he is and increase/change accordingly.  You might also be reaching limits on IO, according to backup how intensive.  In this case, you can move your backup job at a time where it will not interfere with your treatment.

    You run backup jobs with an agent within the virtual machine, is the backup, that you are referring to run in a different way?
