WiFi port turns off randomly in Blaupunkt Cape Town 945
Finally I solved problem. Generally it is work around not real solving problem but it is enough. What is needed:


root unit with init.d support (included in original firmware)
busybox installed (from Play Store)
crond installed (from Google Play)


Add line in cron configuration:

* * * * * /system/bin/svc wifi enable


Thats all!
