The surprising thing for me is that it always worked without any problems before and now all of a sudden these problems appear out of nowhere.
In the past it was always like this, that I was forwarded immediately after entering the login data and now there is a delay of 5-7 seconds, when I have entered my login data.
I guess "delay" is a better word than "lag" in this case.
I mean the unit interaction when I spam windweaver in the forge for example. I can control the units in the forge as smooth as it was before the problems occurred.
It must really be my fault, because, as I said, no one else has such problems.
I was planning on getting a new router anyway. Maybe that'll fix the problem. You never know. I'll report back here.
