Internet access cuts out randomly

I recently moved into a my new apartment which offers included DSL internet access. Every room that has a cable and telephone jack also has ethernet as well, making it very convenient. The only problem is, is that once in a while, as I browse web sites, the internet seems to die on me. I will be at a site such as this reading posts, and after reading one post and clicking on the next, the site will never load. It takes awhile and returns a 'page not found'. I assume its not resolving the address or something? Trying to access any site from that point on is impossible. I can however, ping any site from the command prompt, even though I can't access sites in my browser.

I play world of warcraft and if I am connected to WoW and minimize the game to browse websites, which I do often, and the issue occurs, I don't get disconnected from WoW, I just lose the ability to follow new links. I briefly mentioned this to a friend of mine and he said "its probably dns". Every time this has happened rebooting my PC fixes the problem. I have also tried disabling my connection from the network properties in windows xp and re-enabling it but that doesn't work. So, is there anything I can do personally in terms of my computer to help resolve this problem? Or is it just an issue with my apartment building's router which I can do nothing about?
 
Try this:

Start -> Run -> "CMD" -> "ping 4.2.2.2 -t"

That will run a continuous ping to a Level 3 DNS server. Let it run for a while. Hit CTRL+C to stop it. It will display some info. Report back here with the average round trip time. Also, let us know how many packets were dropped.
 
Here are the results of the ping command:

Ping statistics for 4.2.2.2:
Packets: Sent = 1437, Received = 1419, Lost = 18 (1% loss),
Approximate round trip times in milli-seconds:
Minimum = 14ms, Maximum = 249ms, Average = 18ms
Control-C
 
Sounds like a problem that I had recently with my Internet connection but it turned out to be a bad NIC card.
 
I not sure its my NIC card. I'm using the intergrated Nvidia network controller built in to my DFI motherboard. I've been using it for a long time when I had my own cable intermet at my last place. It has never shown any problem symptoms before.
 
I think it uses DNS for the initial connection to the login server (based on the contents of realmlist.wtf being "set realmlist us.logon.worldofwarcraft.com"), but after that it uses IP (got that from ethereal capture while playing, for bandwidth usage testing)
 
Yes Xipher is correct, WoW uses DNS initially to login, then it uses IP to the actual server I play on, which is probably why I don't lose my connection when I can't browse websites anymore, but can't login if I want to during one of the said 'outages'.
 
Well I found out that my apartment uses Verizon for thier DSL provider and after doing some google searches on DNS issues with verizon I came across a forum thread where a bunch of people were having DNS issues with verizon. One guy said that dowloading a program called Treewalk fixed his problems completely. After installing it, it looks like it worked for me too. The program says it can resolve many DNS related issues such as slowness, or complete inability to connect to sites. It installs itself as a service and handles things in the background with no user input by me at all. I took a look at my TCP/IP settings and it put in its own DNS servers rather than having "Obtain DNS Automatically" enabled. I would recommend this program to others having similar issues. Heres the site if you want to learn more about it: http://ntcanuck.com/
 
I have used the Level 3 DNS servers before, when I was having problems with Charter. Fixed the DNS problems at least... terrible ISP. :rolleyes:

I assume that doing so is not illegal/infringement/frowned upon?
 
No, the Level 3 ones seem to be able to handle the load just fine. If they didn't want other people to use them they would restrict access to them.
