    i'm sorry guys for not being able to reply as soon as possible because its my exams period. i'll probably be able to try the methods you guys suggested when i get back to my hall room later. (probably in another 7 hours)

    and w/o a doubt, my lvl of expertise in this area is just LOW.

    I thank the both of you for providing me assistance.

    The above are what I did. (Once again, with my wifi turned off and on the LAN connection.)


    Something weird that I spotted when I turned on iTunes, I was able to view the shared libraries by my neighbours. (fruit for thought?)

    I have tried what both of you asked me to.

    But they didn't work for me.

    More information, my iTunes have been crashing freely after playing for like 1 song etc. (could it be bonjour?) And I realized that I will tend to lose connection after hibernation, with the same situation as I do now. However, those few times were resolved by just rebooting the system.

    My question for you, and your IT department, is as follow:

    It seems your university own the 137.132.x.x domain.

    Your wireless ip address is: 137.132.5.199
    Your DHCP Server is: 137.132.5.246
    Your DNS Server is: 137.132.0.252
    Your Primary WINS Server is: 137.132.4.5
    Your Secondary WINS Server is: 137.132.4.25

    So...

    Why the heck is your lan connection ip address: 172.19.109.229 ?????????

    Contact the IT help desk and give them this information.

    I just called them up. They will be sending someone over to try to get it fixed.

    still, if anyone has any idea what's wrong here... i will greatly appreciate your help as I need the connection to be up...

    Thanks.

    I agree Lemur, the ipconfig doesn't make much sense to me either.

    If it is the bonjour problem "very likely if you have apple stuff or adobe photo shop installed" try this.
    To fix ...
    Run MsConfig

    Under the Services tab uncheck the service called "##Id_String1.6844[... and then a bunch of numbers]" by Apple.

    To remove bonjour from your system.
    1. Navigate to C:\Program Files\Bonjour
    2. Rename the mdnsNSP.dll file in that folder to mdnsNSP.old
    3. Restart your computer
    4. Delete the Program Files\Bonjour folder

    I helped fix this problem with bonjour just last week, not to mention about fifty other times.
    Competing internet connections...?

    Hey... I've went to my friend's room and ran ipconfig... its providing similar IPs... that Lemur pointed out.

    under the service tab, i am seeing bonjour service instead of the id_string... are they the same?

    once i figure this out, i'll go offline and try.

    Yes I believe they are the same,disable the bonjour service there and it's best to get it off of your system.

    I guess those strange IP read outs are just part of the server's ipconfig. No doubt that bonjour is to blame once again.

    The confusing part was the IPv6 addresses in front of the default gateways which made no sense to me but it looks to be part of this servers routing set up.

    I dislike Apple's bonjour, but it wouldn't have an effect on the ip address.
