Sometimes the WLAN network connection is lost (DM7020HD using the original stick). Symptoms:
- the router does not see the DreamBox anymore as an active WLAN connection
- network test passes using the test inside the system settings GUI !!
- weather plugin displays a DNS error

Remedy: a network restart solves the problem and puts the network into an usable state again.

The main problem is remote access over dyndns in the case of a broken connection. This does not recover by itself. This is annoying because nobody is in front of the box to restart the network in this case.

Does someone else experience this problem? Are there known workarounds? (using a LAN cable is unfortunately not an option for me)

Idea of fix: use of a cron job or another timer framework to regularly check the connection and trigger a network restart if necessary.
