Hi guys,
I believe this is the problem with wifi channel, since obviously you can see there are 11 GPS on the count.
If you are in this case, what should you do?
-Change to another wifi channel?
-Ignore the warning?
-Other suggesion?

These printable calendars are for various reasons

Land it.  You are about to lose the controller link to the Spark.  Then check the radio spectrum channel page to see if you are flying in an area where 2.4ghz and 5.8ghz are heavily used.  It would be good to pick a different place to fly.
