Strange packet loss

[misterkilgore]

Hi guys

I'm a quite a newbie of retropie and linux in general, but i've had moderate success in installing a nice Raspberry Pi3 with everything i need to enjoy al my beloved Atari ST games. Everything worked pretty well until recently, when i started experiencing network issues that prevented me to menage all my roms with WINSCP. While the wifi works, it started having a 50% packet loss that renders everything unusable, it's too clunky even to connect via SSH. I've found the packet loss pinging the Pi3 from my PC.

I exclude network and hardware problems, since the same Pi3, with a SD equipped with Librelec, works perfectly, so it must be a software problem. I don't want to format and reinstall Retropie since i've spent quite some time putting up and running a working configuration, so, what can i do to troubleshoot the problem? Are there some logs where i can look at?

Ideas are welcome!
Thank to everyone

Please add the information requested in https://retropie.org.uk/forum/topic/3/read-this-first to your topic. Have you updated RetroPie - including the OS packages - since you installed it ?

Ok. The Retropie version is 4.3. By trial and error i think i've figured out the problem. In the syslog i've found this error popping out when the packet loss occurred:

Sep 30 15:43:00 retropie bluetoothd[747]: Can't get HIDP connection info
Sep 30 15:43:06 retropie bluetoothd[747]: connect error: Host is down (112)

It turned out that turning on the 8bitdo bluetooth controller resolved the network problem

Now i'm updating the whole stuff to see if this resolves the bug. It's not a problem, but thinking that disconnecting the bluetooth device compromises the network is annoying

@misterkilgore Bluetooth has nothing to do with WIFI. That's how you ssh with WIFI. Maybe a problem with your router or network ?
