problems with crossfire servers

hopefully the ping returns to normal with the new update, because spending too much money on Zp in crossfire and not right because I use it on the server problem ... not share the internet, is free of viruses and my ping was good to the extent of the possible for that is where I live in Brazil, Rio de Janeiro ... I not only how many people not only from Brazil are complaining of oscillation of the ping ... My Internet:: Last Result:
Download Speed: 2079 kbps (259.9 KB / sec transfer rate)
Upload Speed: 477 kbps (59.6 KB / sec transfer rate)

Note: Do not want to lower the ping, I just want him to come back to normal ... is now in 190/300 = unplayable
