sorry my connection wasn't better. I tested my speeds, and put the results in Mbs, so it might make more sense.
I don't think my upload speeds wasn't that hot. I think the 1500 was in kilobits, not kilobytes.
I did check my NAT aftewards, and I'm OPEN. According to the smoothie, the max output I did was 80.6 K, which could have been from speedtest.com.
In thinking about this, and maybe some of the network gurus know more (I'm not computer guru, just lucky and presisent), but my network goes from the modem, to smoothie (hardware firewall), to router (another hardware firewall plus wireless security), to computers/gaming. I didn't think about at the time, but I have my 360 connected wirelessly, which gives max speed of 54Mbs (can't say about actual speed). I can hook it up via eithernet cable, but don't know if that will make any difference.
Other than that, I can't do much about my speed till next month when all my promotions with comcast run out and see what can be done for a faster speeds.
