Raspberry Pi 3 loosing wifi - busy status

[mgouin]

Hello,

I have a strange Wifi problem with my Raspberry Pi 3 setup using Xbian.

I'm connected to my home router using the onboard wifi adapter. I have a good connection and wifi works at normal speed.

After some time (it ranges from one to a few days), the wifi connection drops. The results are the following:
- SSH not working (incoming wifi down)
- Weather, Internet radio, Youtube... not working from kodi (outgoing WiFi down)
- In Kodi: when I go to System, Information: multiple status are shown as busy: Internet Status, Uptime, etc...

If I reboot, everything is back to normal for a few days again.

I would really appreciate to have ideas on how to debug this.

Thanks in advance!

Mathieu
