Random voice chat

I have open mic setting but mute it. Press to unmute and talk, then mute again. During the game, the muted icon will disappear, indicating I am not in chat. I open the social menu, leave the voice channel, then re and it works again. But I do not want to have to do that every game. The only thing that has solved it is connecting to my PC directly from the modem with no router in between.

Is someone just getting bored and pressing buttons now?

I haven't talked in game chat on a microphone since Halo: Reach and note I stopped playing Halo: Reach about a year ago until very recently before Halo 4. The only thing that has solved it is connecting to my PC directly vooce the modem with no router in between.

But I do not want to have to do that every game. You can talk, text-chat, and communicate using webcam.

Blizzard has offered me no other alternatives and suggested I call my ISP I have and they did everything they could and the router technical support was of no help at all and half the time I called over 3 times they had no idea where to even start. I have open mic setting but mute it. I don't even use a mic!

It doesn't really affect me since. I think I may just try a newer and better router and see if that helps, but your issue seems different than mine. I open the social menu, leave the voice channel, then re and it works again.
