    I'm using a Compaq Presario CQ57, and recently it's been randomly disconnecting from the internet, with Google chrome saying that there is a DNS look-up failure. It still says that it is connected to the internet, but with no internet access. I've done everything it suggests to when it happens, but with no success of it not doing it again.

    I have tried re-booting the router, and it makes it work temporarily, before doing the same as above. Also if I turn off the wi-fi signal on the laptop, and back on again it works for a few minutes before disconnecting again.

    It did it for a while just after Christmas, but it's just started again recently. The computer is almost brand new. I purchased middle of December.

    Please help. I'm worried there's something wrong with the computer and it will have to go back.

    Go into your routers settings and set google's public DNS server as your alternate DNS server. Googles DNS server address is 8.8.8.8

    How do I go about doing that? I'm with Virgin, and the 'Super Hub' won't let me edit those settings.

    You can edit them from your laptop if you cant get into the router. It sounds like an internet connections problem and not a problem with your laptop.

    Are you using a windows operating system?

    Follow these instructions.

    1. Go to start menu and seach for "network and sharing centre." Click on it.

    2. In the top left hand corner of the network centre click on "change adapter settings."

    3. Right click and select "properties" on the network adapter you are using (probably the wireless one).

    4. Select "internet protocol version 4" and then click on "properties".

    5. Select "Use the following DNS server addresses."

    6. Enter 8.8.8.8 as your preferred DNS server and 8.8.4.4 as your alternate DNS server.

    7. Click "Ok."


    This will hopefully solve your problem.

    Hmmm that is a puzzler.

    Try removing google chrome and reinstalling it or try using internet explorer.

    Have you got an ethernet cable so you can connect your laptop to the router via a wired connection?

    Seems strange that the connection works for a short period upon wireless establishment but then cuts off.

    Would be worth connecting your laptop with a wired connection to see if it is the wireless connection that is causing the problem.

    Nope I don't but I can acquire one with limited hassle. I'm gonna de-install chrome this evening and see if it makes much of a difference.
    Thanks for the help.

    Sorry to bother you again.
    This is still happening. I have un-installed chrome, and the same thing happens.
    The ethernet cable does work happily. And it does the same thing at uni when I take it there.
    I took it comet today. As usual they were unhelpful, and the woman said it was probably a virus, which I took on board, got back, scanned with avast, antispyware and malwarebytes, and nothing came up except some tracking cookies. RAGE.

    I'm going back there at the weekend with my dad for some extra support and a second opinion at a different store. I just hope this sorts itself out. I can't get on with coursework at uni, when it's like this.
