First things first, I want to make it perfectly clear that I have no other lagging issues in other online games at any time but ESO towards afternoon to evening? Simply UNPLAYABLE.
We tend to do trials and our daily pledges as a guild towards 8pm and we keep on disconnecting with 999+ ping occuring every 5 seconds.
Things I have personally tried so far,
-Resetting my router with flushing DNS (not using a specific one)
-Repairing the game
-Disabling Windows Update & Defender (Not using a 3rd party Antivirus Program)
-Disabling All Addons
-Adding specified ports to my router
-Disabling everything connected to my wireless connection (a couple smartphones)
-Closing down all applications that requires internet connection (skype, teamspeak, steam, origin, discord etc.)
Yet, I couldn't find a solution that would slightly improve the things. Game is just fine late at night and in the mornings but the rush hour? The title says it all, MADNESS.
