    Hey, I have a laptop and use windows 7. Every time I turn my computer off for a while or leave it for a while, the internet won't work when I come back to it. I don't use a router, just straight into the wall at my dorm. This problem only occurs with my laptop, and only occurs in this dorm. It has the same problems throughout the dorm room, meaning in other peoples bedrooms and in the living room/kitchen area it won't work. However, it works in other parts of the building, works at home, and every where else fine. Like I said before, my room mates aren't having any Internet problems, It's just my computer in this dorm room. I have to unplug and replug in the LAN connection a few times to get it to work, sometimes it only works for like a minute, enough time to load a website, then it's out again. After about 5 - 10 minutes of this, it stabilizes and usually works until I leave the computer. I have never turned on the computer and was able to connect to the internet right away. I have tried most of the command prompt commands, ip flush, ip renew, and a few netsh commands, i forget what exactly they were, I can find them if it helps ( I posted here before ). I've reinstalled both my network adapter drivers, for the wireless and the LAN, multiple times with the latest drivers from the website. (btw, same problems for the wireless, my roomate has a router). I have disabled the connection and re enabled it. When I diagnose it always says the DNS server is not responding, even when the internet is working. I have also ran a few different virus protection programs as well as hijack this and posted that up on here also. I was wondering if I took a screen shot of my ipconfig/all if you would then be able to help me from there? Or if you have any other suggestions.

    Please show for when the internet will not work and also for when you have internet access ...

    Start, Run, CMD, OK to open a command prompt:
    (For Vista or 7 type CMD in the Search box after Start)

    Type the following command:

    IPCONFIG /ALL

    [Note that there is no space between the slash and ALL.]

    Right click in the command window and choose Select All, then hit Enter.
    Paste the results in a message here.

    If necessary use a text file and removable media to copy the results to a computer with internet access.

    I think you need to get help from your IT department, and show them those results.

    The difference in the two outputs is the DNS server. I think that can only happen if there are two Dhcp servers on the network--either the network is improperly configured or else, more likely, somebody has connected a rogue router to the network (probably trying to use it as a wireless access point but hasn't done it properly).

    Why it is not causing a problem for anybody else is a mystery, as the results obtained when there are multiple Dhcp servers is random.

    When I am connected through lan, it says the name of the connection is "tinglicious" which is my room mates router name, but I'm connected straight into the wall and have my wireless adapter disabled. I think you're right about the rogue router, what should I do about it?

    ok but it seems almost as if I've figured it out. It shouldn't show up as my room mates router when i connect to a jack in the wall, I'm positive my computer isn't configured improperly and I know that the connections in my room work for everyone else. I'd rather figure it out without having to go to the IT department when I've most likely made a large step further to solving this, I had computer/internet tech guy look at my computer once before and he didn't know anything, he thought I needed a new ethernet cord.

    Good luck; hope you solve it. I am certainly interested in hearing whatever you discover, especially if it is other than what I outlined in post # 7.
