I don't think this is a Quake 3 issue. It sounds like you have poor line quality. Go to <a href="http://www.dslreports.com" target="_blank">www.dslreports.com</a> and do a <a href="http://www.dslreports.com/tweaks" target="_blank">Tweak Test</a> and then a <a href="http://www.dslreports.com/linequality" target="_blank">Line Quality Test</a> and see if that reveals any problems. Also try pinging the Quake 3 server quake3.king-nerd.com and also a traceroute.
