No, Yoshi P stated that switching to a wired connection instead of a wifi connection can possibly mitigate the issue. However the fundamental problem is the massive number of players. The fix to increase the login server limit from 17000 to 21000 has already been implemented.
"The reason for this is that, as a result of longer queues and more time spent in the queue, there is an increased likelihood of issues occurring in relation to the player’s internet connection. In most cases, this is considered to be caused by packet loss on the internet route or instability from the Wi-Fi connection in the player's internet environment."

Also, in the announcement you linked:
"The other occurs when your internet connection experiences packet loss or a period of network instability, causing the server connection to be momentarily disconnected. At the moment, we are seeing more cases caused by this."
The 2002 during queue is caused by connection issues which can stem from the large number of players trying to log in as traffic has a huge effect on connection.
