that firmware should work, unable to tell you what modem version mine is but line characteristics seem to vary alot, there are a few posts on here with line stats miles better than mine at distances similar to mine. Just seems to be the luck of the draw. I can tell you I won`t pay for an 80/20 product unless its free upgrade, thats how much little improvement there is over my current stats
