I bought miracle mini set it up on a VM superhub 2. All tested OK. Took box to my brothers, connected box to his super hub 3, the one that has the 5ghz and 2.4ghz lights. I get glitching. More frequent during evenings and when other devices use the WiFi. I tried new sub line, new ether net cable. My coax connection goes from ground floor upto first floor into a splitter and back down, again split into TV and router. Could this cause loss in packet/ data loss. The free TV don't glitch, just pay TV channels. Would attenuators make any difference? In the daytime its OK, but glitch every 10 seconds or so. Any technical help appreciated.
