Ok 1st off I will give my specs

CPU- AMD A8 5600k
GPU- Geforce GT 520
MOBO- BIOSTAR A55ML2
OS- Win 7 64bit

Ok Im NOT using wi-fi. I have a cable modem. Of course I have restarted the modem, which works for a period of time, but then the problem happens again. I know this could be a problem with the modem but figured I would check here before returning it for a new one for any solutions. My PC will say Im connected to the internet, but I wont be able to get on any websites or do anything "Network" related. It happens at random times, watching netflix, playing a game, listening to music. The internet basically just stops. When this happens I unplug my modem, let it restart, and this solves the problem temporarily. All my drivers are up to date. I heard it could be a IP problem? Anyone got any advice? Its not a HUGE problem but it definately is getting too be too annoying for my liking.

"The 'ipconfig /flushdns' command serves an equally useful function. DNS ('Domain Name System') is the system that maps IP addresses to Internet addresses like http://www.pcstats.com (among other things).
By default, your computer system keeps a DNS resolver cache which stores the IP address attached to frequently used DNS names (and Internet URLs, which are essentially the same thing). This enables your system to bring up frequently accessed web pages quickly, without the need to first consult a chain of DNS servers on the Internet to find out what IP address is associated with, say www.pcstats.com.

If you are in a network that uses an Internal DNS server as the first point in this chain of servers, that DNS server's IP address is...

I did it, hopefully we will see improvement, but could you tell me exactly what this does so Im more informed on how to help other people with similar problems in the future lol? I will say everytime Ive refreshed my page it went kind of slow, then I ran the ipconfig in cmd and I refreshed and it was instant, so hopefully this did SOMETHING lol

This enables your system to bring up frequently accessed web pages quickly, without the need to first consult a chain of DNS servers on the Internet to find out what IP address is associated with, say www.pcstats.com.

If you are in a network that uses an Internal DNS server as the first point in this chain of servers, that DNS server's IP address is going to be a more or less permanent resident of your DNS cache. So what happens if that server changes or goes down? Even if there is a backup, your system still has the original IP address in its cache, and will check that address first whenever you type in a request for a web page. Obviously, querying a non-existent DNS server is not going to get you far. Unfortunately, even if you change the address of the DNS server to a valid one in your network connection settings, your system will ignore it in favour of the entry in the cache. This can lead to much frustration.

By using the 'ipconfig /flushdns' command, you delete the contents of the DNS resolver cache, meaning that your system will now recheck its settings to see where it should be going to get DNS addresses. Problem solved.

The 'ipconfig /displaydns' command will show you the current contents of your system's DNS resolver cache "


easiest way to describe what it does :)

glad to hear
