Recently I exchanged the old rogers modem to the new Hitron CODA -4582 .
With this the speed is slight better with asus router : Upload - around 120 and download around 20-25Mbps.. This is totally bad on a Gigabit modem but I am being forced to use the Asus router. The reason i am using the Asus router is that with even though the rogers modem shows Download around 400+ there is buffering of youtube and when I download large files over 500mb on some sites it stops around 160 to 200mb. The download issue can be overcome if I use a VPN.. This is something that rogers is doing... Till I figure the issue I have to use the Asus router.
