yeah I've done those instructions in you're sig, the only thing I haven't tried is an tweaker! i however got some help from a covad guy and we tried a differnt test and I am getting over 8,000 kb/s so I am actually doing well...we couldn't really figure out why is was so much slower on testmy, but even cnet.com has confirmed simialr results as speed test servers have outputed! I will look into seieng if my sb 5120 modem is outdated and if so...request a different one!
