Huge lag

[Pakarro]

When connecting to ps, problems start on the server connect screen. I get all from Failed to huge numbers (>10000) in the server line, where I used to get around 80. Connecting is still possible, pinging always gives low numbers in the 50 ms, or below.

When I connect, I have incredible lag of a few seconds before the server response to my key-presses gets back to me. Even when mining

Further checks: I connected over cellphone and laptop, ok. And also no problems connecting from the laptop. - Although generally slower (server at 300....), but nicely playable. WLAN router is on the same line as my game computer.

Does someone have an idea where to look?

Thanks, and Have fun!

If your ping time is ok, your internet connection should be aswell.
What I can think of is, that your client lost hardware accelleration of the client. Thus, it's busy calculating graphics and reacts slow on network traffic from and to the client.
(another thing could be that your provider slows down traffic on high ports; but I never saw that acually happening)
