I don't think it closes the vivoxservice process entirely, but it will be enough to resolve any issues caused by the chat service. How old is the modem you're using? Have you had it for several years now? In the past I had an issue with the modem supplied by my ISP and it sounds similar to the one you're reporting. Once I had the modem replaced the problem cleared up. ISPs tend to reuse the same modems quite a bit so it's possible that your model is worn out.
