Hi. Thank you your reply and feed-back. I tried to notice if turning off the TV and soudbar would make a difference. I also disconnected the subwoofer since this is the component that uses Bleutooth. It seemed to have made a difference for a while (hence the delay for checking my post for replies), but then Friday and Saturday this week, we had the same Internet disconnections issues as before (usualy 4 or 5 times a day).
I will try what you suggested and unplug de soudbar. To answer your question, the soundbar and Helix are right next to eachother. Intially, Helix was on the bottom shelf under the TV. I moved it on top of the TV unit (next to the soundbar) because Videtron Website said the unit should be above the ground and unobstructed from furniture. So I will also try to reposition Helix (or the soundbar) so they are at least 3 feet away from eachother.
Thanks for your advice. I will keep you posted if what you suggested worked.
