Recent Bad Ping?

[Sargent Q]

Yeah I've had that problem past couple of days.  And then today i went and joined a eu server and even with my ping staying the same, the game was lagging badly.  I then went to rag na2 and it was doing the same thing for me.  Is it just my internet or are other people having this problem of ping stay about the same but the server lagging bad enough to cause the ammo refill to not work?
