i now only connect lan cable to get updates and then disconnect it. I have a AVOV box for IPTV so F10 receiver is only needed for satellite.
I like having powervu and works ok.
If your mostly wanting to view Satellite channels rather than IPTV channels, then a suggestion would be to go back to an older firmware release (20171512). There are less power related and channel scanning issues compared to the later releases for both Single and Multi satellites. I believe the later releases are more geared up for IPTV viewing, and has had an impact to some of the satellite functionality.
Dont forget to do a factory reset after the firmware has been updated.
