I’m running OSMC for about 1 1/2 years on my RPi 3 now and used openelec before that for several years on my RPi 1b. I am really happy with the Software but have one particular issue now and hope you can help me out.
I have used a tiny 2.4 Ghz Wifi adapter (EW-7811UN) since my beginning with the RPi. But then I moved into a new home and have to deal with a highly congested wifi area since - primarily in the field of 2.4Ghz.
I wasn’t able to stream any HD content without permanent bufferings - even with an adjusted advancedsettings file. Thus i decided to give my Pi a little upgrade and was recommended the Edimax EW-7612UAn on several forums. Long story short: Sometimes I was able to stream HD content but often I wasn’t. I would say especially in the evening this was the case - probably a peak in data transfer in all the other WLANs reducing the performance of mine.
Now I got myself a third Wifi adapter in the hope to finally solve my problem. This time one with 5 Ghz support. The EW-7811UAC.
My other devices are running nicely in the 5 Ghz environment and there is only a second Router on this frequency, thus there is no interference between mine and other networks.
Starting a HD movie on my RPi 3 with the new Antenna in the 5 Ghz network is lightning fast. It streams perfect! BUT! After some time - and this may be between 1 Minute to several Minutes (>20) the video suddenly stops and I am back in the kodi menu. I never ever had this before.
Asus RT-AC66U + USB Harddrive attached via smb
2 ampere power supply
I did some debug log tests and found that the Pi says “connection timed out” right before the stop happens. Connection is perfect and Up-/downstream as well as my router says.
Some people with similar problems were suggested to adjust “advancedsettings”, disable Background Updater of Connmann and such but this did not help me at all. I came to the result that it might be a peak in power consumption of the Pi, which is in return disabling the USB interface for a short second because my power supply might be too bad. However, I did never see the lightning bolt sign again after I upgraded to this power supply a while ago. Is there a way to see somewhere in the log if it is an issue of insufficient power? Like an entry of “usb device removed/disabled” one might know from windows ;-)?
Before I run to the next place buying a new power plug for my Pi after i spent money for 2 “usless” wifi adapters in the first place makes me really want to think twice about it.
Regards and thanks in advance!
