Hello – I have Optimum (Cablevision) as my ISP. They have provided me with a Cisco 2203C cable modem. From the modem, I am connected to my Linksys WRT600N router and from the router to my HP computers and my Linksys Media Hub (used for shared external storage). The problem that I have been living with for a while is that my Internet speed (as determined by Speakeasy) gradually degrades over time (matter of days) from over 20 Mbps (download speed) to less than 3 Mbps. The upload speed apparently does not change (stays about 2 Mbps). The only way I can recover the speed is to do a "release" then "renew" the router's IP address. This brings the speed back to 20 Mbps, but only for a day or two, before gradually dropping to 2-3 Mbps. I have been doing this every few days for a long time, but I am hoping that there is an easier solution to my problem.
