I just got an install of cable (no contract/trial) Got on the internet and Xbox live in minutes. I noticed there was some lag on my online game, so I did a speed test. It showed it was 5+ megs/sec (an improvement over DSL) But then I checked packet loss and latency. It showed 58% loss up to 80% loss and graded it an F. One guy with this router says he also showed an 58% loss (same as I) and fixed it by turning off the firewall. Is this dangerous? What alternatives do I have to clear this up? I am not with Comcast. I am with Cable One in the Midwest. Thank you!
