I've looked for steps everywhere, and all guides seem to point towards the same point, "reinstall", "verify this games files are installed correctly" and so on.

I enter the server, manage to play if lucky five minuets, soon as I see red chain link pop up I know I have only moments before I'm booted to the main game menu with "warning (0x00040004) you were kicked off the game, connection with the host has been lost".

I have reinstalled, verified files numerous times, to the point I've lost count, never had this issue ever before in all my years in playing Dayz.

see attached video, get this issue each time since upgrading and reinstalling Dayz. Only other change that happened other than just standard hardware upgrades, has been an upgraded internet provider(got better internet pretty much). And the fact that I have switched to a dual band USB adapter from a TP-Link WPA4220 WiFi adapter kit.
