The steps you need to take:
1. Ensure that the wifi is working with a known SSID and password (SSID security/ encryption).
2. Please see that your linux client is able to see the SSID and the password is accepted.
3. Please see that the server is sending the data on the right port (http: port 80 default)
4. Note the client IP address and point the linux browser to the correct IP. Ensure that you can ping the IP address.
5. Can see any data coming to the browser?
6. Check the video format being transmitted by the client.
7. Check that all the relevant drivers are in place in the linux client.
8. If you have reached this point, the video data are stored in a temp file in a temp folder on the client.
9. You need to work a bit more to save the data.
