Why don’t you think that the problem may be and from the router by itself, maybe because it is old or it is having other issues. I had that kind of problem on my mac, but it got fixed as soon as I bought my router and configured it to let me everything I need, you can see more if you are interested in what I did, I mean not to block any apps, media or even sites.
