I have 3 devices, and only the HD5 is studdering. The Other Formuler Pro and X5 are playing fine. This happened on at least a dozen other channels, I checked on the HD5.

I have unplugged it and plugged it in again. 

Anyone know what could be the issue and how to fix it?

Box seems to have fixed itself. I rebooted it again.

For next time, Just to rule out a wifi issue, have you at least tried with an ethernet cable ?

Since the HD5 has dual band wifi, have you tried splitting your 2.4 and 5Ghz bands (disable band steering at the router) and try to force connect to 2.4Ghz and 5Ghz and see if either one makes it better ?  5Ghz may be faster but range is shorter and can be temperamental with showing full bars one second, and then showing 1 the next.  2.4Ghz may be slower (but still plenty for most iptv typically), but range is longer and can typically have a more stable connection.   If you don't split it, then the router decides if it will move you to 5Ghz or not (which may not always be the optimal situation).

 

 

 

I am connected by Ethernet cable on all boxes. Thanks for the reply and tips!
