# Offenes WLAN: UniHGW

This source describes the **UniHGW** open Wi-Fi network provided by the Universität Greifswald. It is designed as a secondary access point to the more secure [[eduroam]] network.

## Purpose
The primary goals of the UniHGW network are:
- To provide short-term guests with unhindered internet access.
- To allow users with devices lacking wired network interfaces to configure [[eduroam]] without relying on mobile data.

## Technical Specifications and Constraints
Unlike the primary university network, UniHGW has several specific technical characteristics:
- **Connectivity**: It does not use the DFN X-WIN science network; instead, it operates via a separate DSL internet connection.
- **Authentication**: Access is granted only after registering as a guest via a [[captive-portal]].
- **Limitations**: Both bandwidth and the maximum number of concurrent users are limited.
- **Resource Access**: The network provides internet access only. Access to internal university resources or licensed online publications is not possible without a [[vpn]] or [[shibboleth]] authentication.

## Recommendations
- Users are strongly encouraged to use [[eduroam]] whenever possible.
- For conferences, dedicated conference access (**Tagungszugänge**) should be used instead of the open UniHGW network.

## Support
Technical support is provided by the [[universitatsrechenzentrum-urz]] via their [[groupware]] ticket system or the central hotline (ext. 1420).
