I have RPI 3 model B and i use it as a HTPC via wired ethernet. Bluetooth and WiFi are turned off.
I run LibreELEC on it and use Kodi for playing media, i also use the Tvheadend PVR client.
Recently i moved my PCTV tripleStick 292e TV Tunner from another PC to this RPI 3, and installed Tvheadend locally on the RPI 3 also.
The major issues that i am starting to have now is the low voltage thunderbolt icon, and frequent buffering while playing TV, especially with the HD channels. Sometimes it does not respond at all and/or freezes for a short period.
I have a 5V/2.5A power adapter, with a 1M 20AWG micro usb cable.
So far i tried to introduce this usb powered hub: https://www.hama.com/00078472/hama-usb- ... dboard-box
But the RPI 3 just freezes when i plug it in while running. And if it's plugged in before powering the RPI 3 on, the TV tunner is not recognised as plugged in. Somewhere in the boot process the TV tunner led shuts down, it's on in the noobs part of the RPI 3 boot.
What should i check?
Should i move to a more powerful power adapter?
A shorter micro usb cable?
Another powered usb 2.0 hub?
A 18AWG micro usb cable? (not sure where to find these)
