Internet static ip - windows has connection; mac not!

Hello everybody,

my girlfrien has the follwing problem: She is for an exchange semester in china and received the following login data for the internet connection in her studend dormitory:

IP: 211.080.093.137
subnetmask: 255.255.255.128
Router: 211.080.093.254
DNS: 202.120.2.101

Entereing these data into a windows laptop the internet connection establishes. If she enters them in the network-interface of her macbook pro it shows that it is connected but she has no internet connection.
The status of the connection is showed as:
"Ethernet" is currently active and has Ip adress 211.080.093.137

The router is not in her room and she has no information about it except of the ip adress. She tried to ping it but without success.

If she tries DHCP her mac assigns himself the following adresses:
ip: 169.254.143.130 und
subnetmask: 255.255.0.0

The status of the connection is shown as:
Connected - Ethernet has a self - assigned IP-adress and is may not be able to connect

We already tried to enter sole ip in the browser e.g the one from heise: 193.99.144.85 to check if its a DNS problem but that didnt work. Ping this site didnt work as well.

She is currently running a ifconfig -a and i'll provide this information here as well as soon as i have it myself. ( from time to time she can use the w-lan connectioin of a friend of her there)

Does anyone has any idea what is the reason for this problem?
This is the first time that a windos machine performs better in the first place than a mac - it really shocked me as the fan that i am.

It would be absolutely great if someone could help us! She is there since one week and the communication withoud internet (mail, skype) becomes increasingly expensive...

Thanks a lot for your help!

I know that one ip adress is only for one device. The thing is, that if she puts the same cable that doesnt work with the mac in a windows laptop - the windows laptop has internet connection, the mac has not. It was never meant to have two devices on one ip adress.

 

Since she sent me a screenshot of her network settings panel i am shure that she didnt forgot to insert the net mask.
Am i right that MAC filtering means that her ethernet card is probably not on the white list of the used MAC filtering procedure. And that this is a problem that hardly possible to handle without trying to explain it to a only chinese speaking ISP at the shanghai university ;-) But she will try this of course as well - the thing is that the service is closed till the end of the week...

Is there an other possibility except from MAC filtering?
And am i right that in such a filtering some laptops do have access because their cards are by chance on the white list and they simply forgot to add the macbook pro cards - or do all laptop holders have to go to the ISP to get an entry on the white list? ( that seems not to be the case)

btw: woher kennst du meine muttersprache?

 

No idea why but the described option manually-advanced from the link is not present in my network controle panel ( i really checked it )

Das mit dem Lucky Strike ist nicht schlecht! Aber ich hab leider nicht in Mhn studiert (was ist das für eine Stadt btw? ) Dafür studier ich in Saarbrücken Bioinformatik...

 

not the MAC adress

Ok it seems that it is not the MAC adress since there are two guys with windows laptops that have internet access with the cable.

My girlfriend wrote something about the 801.x connection that is weird - could the problem be related to that.

Or what could it be if its not the MAC adresses?
Has anyone an idea??

Thanks
Jo

 

When she signed in she didn't need any mac adress. It seems that the problem is not caused by MAC adressing.
She told me that the only difference between the preferences on her mac and on the windows pc's on which the internet works is this 801.x thing.

But can it be something else?

Except of MAC adressing and 801.x ?
