Connection to apple

Normal connection to Apple is okay. I can obtain 300 MB set up recordsdata in a couple of minutes.

I do not assume there’s a firewall problem, as I’ve no downside doing this from one other pc working Excessive Sierra. I’m presently utilizing wifi as an alternative of cable, because it’s a simple solution to change IP addresses. Similar behaviour.

Applications like Transmission torrent downloader works superb.
