Windows 7: Unable to USE internet connection (WiFi)

Unable to USE internet connection (WiFi)

Hey.
I'll jump straight to my problem to keep things short.
I seem unable to use my WiFi connectivity on my notebook. By this I mean that I cannot surf the internet or download anything using download managers <IDM and uTorrent>.
However, strange as it may be, Windows is able to connect to the microsoft update servers and carry on the Windows updates. So I guess it's not a driver problem.

I started experiencing problems with network connectivity a few days back, when my notebook would automatically disconnect from the network when my dad would connect on his notebook. I tried setting the IPv4 IP and DNS manually (thinking it might be a network conflict?) but that didn't solve the issue.

Anyways. Now I CAN connect to the internet while I'm surfing the net on dad's notebook. That is, it shows it is connected to the network and windows updates work fine. But the main problem still persists, dad's notebook switched on or not.

I haven't tried a wired connection yet - I don't have an ethernet cable. .__.

My drivers are up-to-date.

Extra info, might be unnecessary:
I've tried Google Chrome, Firefox 4, IE9.

Chrome says: Error 137 (net::ERR_NAME_RESOLUTION_FAILED): Unknown error.

uTorrent says it has a "listen error" and asks me to change the listen port.

I can PING update.msdn.com from CMD.
I can PING Google, gmail.com, wikipedia.com, yahoo.com, youtube.com.
I can PING 192.168.1.3 (dad's laptop)

BUT I CANNOT OPEN THE SITES IN MY WEB BROWSERS. Annoying.

Have you checked your system for any malware, spyware and Virus's? Sometimes these can reak havoc on your internet connection. If that doesn't work, a system restore to a point and time before you started experiencing your disconnect issue.

NAV didn't detect anything. I do full system scans on a regular basis (twice a week). Running MalwareBytes just in case.

After the NAV scan I tried restore. Didn't help either.

Hope MalwareBytes detects something and fixes it. =(

See if resetting the Hosts file helps ...

Download the http://www.funkytoad.com/download/HostsXpert.zip
HostsXpert 4.3 - Hosts File Manager
  • Unzip HostsXpert 4.3 - Hosts File Manager to a convenient folder such as C:\HostsXpert
  • Click HostsXpert.exe to Run HostsXpert 4.3 - Hosts File Manager from its new home
  • Click "Make Hosts Writable?" in the upper right corner (If available).
  • Click Restore Microsoft's Hosts file and then click OK.
  • Click the X to exit the program.
  • Note: If you were using a custom Hosts file you will need to replace any of those entries yourself.

Nope, the hosts file was fine (I didn't download the app though). I should have mentioned this earlier, apologies. First thing I did was check my hosts file, and uninstall DNSKong (use it for adblocks). It was a Malware after all (or some kind of infection in the registry )

MalwareBytes found an infection in the registry. =)
Turns out MalwareBytes is better than NAV. =D

The problem is now solved. Thanks a lot for all your help and support. =)
