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.

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.
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.
