I have been playing America's Army Proving Grounds for quite a while now and I have always played on international server with a ping of 300 to 500 which was very bad and laggy but I had no choice as there was no local servers for me to play on until about 2 months ago when a few local people hosted their own server. I could then play with a ping of about 50 to 80 which was great. I played like that for about 2 months until now when my ping is suddenly no lower than 250 on the local server I have been playing on all this time with a 50 to 80 ping. I asked the host of the server if his ISP is having problems but he said no and that the ISP was fine. I also did a lot of research about this but couldn't find anything that works for me.
Can someone please help me get my ping back to 50-80 on one of the local servers? I am out of ideas and nothing seems to work.
