On my PC I am Rinning Win XP Professional. I have Comcast cable modem service which has always worked seemlessly (no dropped connection) until I installed a Linksys 4 port router. Since setting up the router I get dropped constantly. Sometimes I will turn on the machine and it will run fine with no connection loss other times it will drop the connection every 2 minutes (literally). I have to release and renew the IP to regain conectivity and sometimes this only lasts for a minute or two. I am set up for DHCP through the cable modem and I have configured the router settings for the same. Under advisement of Linksys tech support I have also set the MTU to 1500 but I am still loosing connectivity. I do run Zone Alarm but I have it set to allow IE full access. Any help would be greatly appreciated!
