Good evening Xing,
This is a quick link to the most recent and complete version of my “first-aid-kit” list of settings to check first; for your case specifically, selecting “Do nothing” under the Communications tab, would seem like the first go-to point.
It would be nice if you could run through the list and apply the tips that seem the most useful and practical to you, then post back with your results; if the problem persists after that, we can explore further options - I’ll be online for at least five more hours.
