Running RVS4000 on a Comcast HSI line. With the lastest firmware 1.2.11 (and the older version as well) IPS is killing my speeds. With IPS on I can only run 12M down, 5M up; shut off IPS and I'm at 24M down and 10M up. IPS is knocking my speed in half. I could see some loss from due to inspection of the packets but 50% drop, wow. Anyone else seeing this? BTW, when I take the router out and hook the computer to the modem, I see the same speeds as I do with IPS off.
