- | **Interface**: Select the desired inteface. \\ | + | **Bandwidth: auto(WWANX) ** \\ |
- | **auto**: Qos manages the bandwith according the configured priority.(1=high/10=low). \\ | + | IP to ping: Configure a reachable host in the internet, preferably the target host. \\ |
- | IP to ping: A host is needed in order to measure the current bandwith. \\ | + | Based on the RTT the bandwith ratio is divided as follows: \\ |
- | **fixed**: QoS works with the configured settings. The amount of bandwith should never be higher as the available bandwith. \\ | + | higest priority = 50%, \\ |
