A rule of thumb is 2 MB per product shown. Additional screens showing the same material does not demand an increase in network connection bandwidth. **Connecting player hardware to wireless network** * Broadcasting SSID * The wireless network needs to have Broadcasting SSID * The wireless network needs to have WPA2-PSK encryption with passphrase *(open unencrypted networks will not work)* * The wireless network needs to have proper and stable signal strength. * The two Wi-Fi antennas included with the player hardware must be mounted. Furthermore, if the SSID or the passphrase is changed the player hardware must be reconfigured. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://shoppa.gitbook.io/knowledge-hub/systemkrav-eng/digital-signage.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
