It used to perform very well. I had connections speeds up to 7.2Mbps on a line with 34db attenuation and an snrm of 5. no errors for most of the day would start getting errors in evening when snrm would drop to about 2 or 3. its in the last 3 weeks that its got bad .Mind you with tiscali as my ISP I am still connecting at 5Mbps or better ,which is way way way above the DL speed available most of the evening and week end.I am getting all my data together for my next topic. Yes the firmware is ok I think 330 1.0.12 1999-2004.
