Phenomenon: If WIFI is working normally before hibernation, the WIFI system icon cannot be seen in the lower right corner 20 seconds after waking up from hibernation
Reason: When waking up the system, WIFI occasionally fails to wake up, the probability is extremely low
Solution: Re-enable WIFI (Desktop->PDA Settings->WIFI->Turn on WIFI)
If it recurs multiple times, consider restoring to factory settings or disabling system hibernation (Desktop->PDA Settings->Hibernation->System Hibernation->Never)
