DNS Server problem

Ok so I have a what I presume to be a networking problem.

IN the first 5 minutes of starting up my computer, I have access to the internet via internet browsers like Google

Chrome and Mozilla. However, after those 5 minutes, whenever I click a new page, it takes a long time to load and

eventually it stops loading.

Mozilla tells me this:

The connection was reset


The connection to the server was reset while the page was loading.


* The site could be temporarily unavailable or too busy. Try again in a few
moments.

* If you are unable to load any pages, check your computer's network
connection.

* If your computer or network is protected by a firewall or proxy, make sure
that Firefox is permitted to access the Web.

while Google Chrome tells me this:


This webpage is not available.

The webpage at http://www.google.com/ might be temporarily down or it may have moved permanently to a new web

address.

Here are some suggestions:
Reload this web page later.
More information on this error


I am fairly certain though that I am still connected to the internet because my torrents are

running/downloading/uploading/seeding and my Windows Live Messenger is still running. However I am unable to access

website pages.

The blue network icon at the bottom right hand corner of my computer tells me I am currently connected to my

wireless network and Access: Local and Internet.
When I click on diagnose problem, Windows Network Diagnostics tell me:

Cannot communicate with DNS server (218.186.1.58)

Network diagnostics pinged the remote host but did not receive a response.

Windows found a problem that cannot be repaired automatically...

My results of Command Prompt:

So what indeed is/are the problem(s)? I have tried "ipconfig/dnsflush", "ipconfig/registerdns", "netsh winsock reset catalog" and "netsh int ip reset reset.log" but apparently they do not work. The only way around it is to switch off then on my modem and router only to have them fail on me again after 5 minutes.

Thanks in advance.

What happens if you change your DNS servers to:

8.8.8.8
8.8.4.4

(Google's free DNS servers).

Where or how do I input those alternate DNS servers? In TCP/IPv4 or TCP/IPv6? In my router settings or where? I have tried several places using trial and error but they do not work.

Does OpenDNS (208.67.222.220 or 208.67.220.222) make a difference?

In TCP/IPv4. Once you get them in there right, they'll show up in the output of the "ipconfig /all" command.

And yes, either Google's DNS or OpenDNS's are fine. (Both are working for me right now, here in the USA).

Ok if I use either Google's DNS or OpenDNS servers, Windows Network Diagnostics tell me: Cannot communicate with DNS server (The DNS address I used)

However, after some meddling with the router settings, something is different now. If I set my TCP/IPv4 back to "Obtain DNS server address Automatically", Windows Network Diagnostics tell me: Cannot communicate with Primary DNS server.

Is this indication a good thing or what?

None of the DNS servers you have listed in your "ipconfig /all" results, (218.186.1.58, 202.156.1.68 or 202.156.1.78), respond to a ping request, (from here in South Florida, USA anyway).

If they don't respond to a ping from your end, you may need to call your Internet Service Provider and ask them which of their DNS Servers you should be using.

218.186.1.58 and 202.156.1.78 both comes back to Singapore, specifically DNS servers of Starhub Cable Vision Ltd.

However:

202.156.1.68 comes back as being the DNS server used by various trojans.

Malware forum me thinks.

Ok thanks guys for all the suggestions but the problem seems to be fixed. After some more meddling with the router settings, during which it went haywire, I decided to reset everything (using the disc the router came with) and it fixed the problem, for now I guess.

I will post again if I run into future problems though. In any case, thanks for all the wonderful suggestions.
