Problems connecting to internet (please help!)

I live in apartments and share a connection with 6 people and decided to get my own connection with 2 megs only for me so I can skype and game in peace. So the tech came and installed my connection through my phone line that I have here in the apartment. He configured the router, made sure everything was working on my laptop and then he left. This all happened yesterday.

I used the internet for a while and everything was working fine but then I needed to go to work so I turned off my laptop and put it away. When I got back home I got out my laptop, fired it up, then plugged in the ethernet cord but this time I got the little horrible yellow symbol with the ! inside which says I don't have internet access. Here is a pic of what I saw...

However, I noticed that besides the connection that he configured (Network 2 in the photo) there is another network on the list that says "Unidentified Network" which also has no internet access but I'm only connected to 1 network and I have the settings so that my laptop doesn't connect to the wireless connections for the apartments unless I manually connection. I tried to into network and sharing center to perhaps disable that connection or whatever but it wouldn't let me do that or maybe I didn't do it correctly.
( I am running Windows 7 Ultimate 64 by the way )

I tried to manually reset the router and do the normal troubleshooting steps but I got the same results. I logged into the router to see if the settings were ok and the diagnostics said that everything was ok but the DNS failed. I called the ISP to get some support and he had me do all sorts of troubleshooting for like 45 minutes but we couldn't get anywhere and he told me that it is probably a setting in Windows but I honestly have no idea what is causing this problem.

Have any of you ever experienced this problem? Any helps/suggestions will be appreciated. Thanks in advance guys.

 

Check the details in Windows- what's the gateway, DNS, IP and so on.

 

IT is totally normal with DSL to have Unidentified Network (and no access with it). Was part of the troubleshooting to power down the modem, disconnect the phone cable, reconnect the cable and power back up.
IF this settings look good (as downloads said) login to the router and try Google DNS servers.
If you want to use Google’s DNS servers, you can add the following two items to the list:
•8.8.8.8 (Pri
•8.8.4.4 (Sec

 

Wow, after doing some research it turned out to be the weirdest thing that was giving me trouble. I read that if you have Adobe Photoshop or Dreamweaver CS3 there is a service that can cause trouble when you are trying to make a direct connection to your modem.

So if any of you happen to encounter this same error and have Adobe PS or DW CS3 give this a try...

1) Go to start and search for "msconfig"
2) When your in the program go to "Services" tab
3) There should be a service called "##Id_String1.6844F930 (then more numbers)" in the list
4) Simply disable it by unchecking the service.
5) Reboot

That should work for you if you had a problem similar to mine. I actually don't even understand how I have that service on my laptop because under manufacture it says "Apple Computer, INC." But I have absolutely NO apple software on my machine. Pretty strange, but this worked for me. I don't know if it's just a temporary fix or whatever but so far so good.

Thanks for the suggestions anyways guys. Peace!
