Yo, I get some kind of weird ping lag? Everytime after 7 pm. (+-) my ping goes from 50-60 (casual) to 90-100 ms. It appeared after I re-install Windows system - but it seems like it has nothing to do with it. After testing my internet connection (It says the quality of connection is better than 81% for Czech republic users)so I found out there isn't problem as well. Also it's only problem of M&B: NW. I haven't tried all the NW servers but for example the Turkish ones are OK for me. Another example are servers NWWC S6 and NWWC S4, as for NWWC S6 I get high ping and as for NWWC S4 I get the casual one.
And because i think there aren't many of providers of the servers so most of servers are hosted by the same one, there might be someting wrong on their side since I'm not the only one who has the problem.
I'm very competitive player so I would be grateful if anyone will actually help me.
