Internet access in the dormitories 9905, 9906, 9907 and 9908

Upgrading of the central network components

In the coming weeks, we will be replacing the central network components in these dormitories with new, more modern equipment. The transition will be carried out one dormitory at a time. All tenants of the affected dormitories will be informed in advance about the specific switchover date for their building through posted notices and flyers.

IMPORTANT: At the time of the switchover, all devices connected directly to the network outlets in the apartments (including Wi-Fi routers) will require a settings adjustment. Further information, instructions, and contact details can be found here, updated at any time: Internet Access in the Dormitories.

The necessary reconfiguration of existing setups will greatly simplify device setup for all future tenants. Likewise, when moving between apartments or dormitories, no configuration changes will be needed. In addition, the new connection type will also support additional devices such as switches and access points straight away. Along with a more stable connection, the monthly high-speed data cap (traffic.campus-company.eu) will be eliminated in the future. You will always receive the maximum available bandwidth.

Each network connection in the dormitories is assigned a fixed IP address and a fixed monthly quota of high-speed traffic. The contingent can be requested from your own connection at http://traffic.campus-company.eu . Only the data consumption (traffic) to the Internet is counted. Internal university traffic (except VPN connections) is not counted. If the high-speed quota is used up, your network connection will be throttled in bandwidth for the rest of the month. Further information on this bandwidth restriction can also be obtained from the URL above.

Only the IP address assigned to the apartment may be used. In case of misuse, the connection will inevitably be disconnected from the network. If you have used an incorrect IP address, you will have to wait until the next full hour for your connection to be reactivated. During the disconnection you will receive a message that no network cable is connected.

Instructions

Please follow only the guide that matches your connection type — no other steps or configuration are needed.

Setting up your own WLAN router

If you want to broadcast a WLAN network in your apartment, you will need a WLAN router.
IMPORTANT: WLAN repeater or WLAN access points unfortunately do not work here. A frequently used and inexpensive model is for example the TP-Link TL-WR841N.

Setting the IP address on a router:

NOTE: The configuration and menu structure varies greatly depending on the device. Therefore we cannot provide instructions for all devices.

  1. Connect your PC either with a network cable or via WLAN to the router you want to use in the dormitory.
  2. Open the configuration interface of the router in a web browser according to the instructions manual of the device (usually it can be reached at the following IP address: 192.168.0.1).
  3. Log in there with the login information from the manual of the device.
  4. Find and open the menu item Internet access or WAN access.
  5. Change the IP settings there from dynamic to static.
  6. Then enter the data according to the slip of paper you received from your operator:
    • IP address: 143.93.XX.XXX
    • Subnetmask: 255.255.255.0
    • Gateway: 143.93.XX.1
    • DNS server: 143.93.32.2
    • 2. DNS server (alternative DNS server): 143.93.36.2
  7. Now connect the WAN socket of your device to the computer socket in your apartment (normally the left port) using a network cable.
  8. On your end devices (smartphone/tablet/PC) you now only need to connect to the WLAN router. Further settings are not necessary.

Basically we recommend that you make the following settings on your router:

  1. Change the name (SSID) of your WLAN network so that it cannot be traced back to the model used.
  2. Change the password of your wireless network to a long password and use the WPA2 standard (not WPA).
  3. Disable the WPS function, if available.
  4. Leave the wireless channel settings on Automatic to minimize interference.
  5. Change the password used to log on to your router (the password used to access the configuration page).
Windows (access via network cable)
  1. Open the IP settings of your network card at your device: Start → Settings → Network and Internet
  2. In the right column under Change Network Settings, select Change Adapter Options.
  3. Right click on Ethernet → Properties
  4. Internet Protocol Version 4 (TCP/IPv4) → Features
  5. Then enter the data there according to the slip of paper you received from your landlord:
    • IP address: 143.93.XX.XXX
    • Subnetmask: 255.255.255.0
    • Gateway: 143.93.XX.1
    • DNS server: 143.93.32.2
    • 2. DNS server (alternative DNS server): 143.93.36.2
  6. Save the settings and connect your device to the computer socket in your home (usually the left port) using a network cable.
macOS (access via network cable)
  1. Open the IP settings of your network card at your device: Start → System settings → Ethernet
  2. Configure IPv4 → select manually.
  3. Then enter the data there according to the slip of paper you received from your landlord:
    • IP address: 143.93.XX.XXX
    • Subnetmask: 255.255.255.0
    • Gateway: 143.93.XX.1
    • DNS server: 143.93.32.2
    • 2. DNS server (alternative DNS server): 143.93.36.2
  4. Save the settings and connect your device to the computer socket in your home (usually the left port) using a network cable.
