Agree with - RoBur - here. The game in the evening hours is just not playable. Client, internet connection, device - all of this is irrelevant, no matter what setup You use, the result will be the same.
I know a few players who have the exact problem though apparently it doesn't apply to everyone. Maybe it's issue with the account itself? Well, I guess not everyone here are equal...
Truth be told, this was happening to me for few years now but in varying intensity. Sadly, I wouldn't expect them to do anything with this.
