Router - DLINK 320B: Difference between revisions

''Performance tip for long lines:'' If you have an extremely long phone line (>60 dB downstream attenuation) and you have an ADSL2+ service, it is maybe worthwhile experimenting with setting the DSL mode/standard option to ‘ADSL 2’ (only) in the list of options, that is, taking ADSL2+ out of the list of allowed standards, as opposed to allowing the modem to use ADSL2+, to see if this restriction gives a performance improvement. It will be a long process to get a meaningful comparison with many restarts and many tests needed to confirm any possible performance difference between allowing and disallowing ADSL2+. If in any doubt always enable ADSL2+ or ‘auto' mode ie ADSL1/ADSL2/ADSL2+, where the modem will use ADSL2+ if the exchange’s DSLAM or MSAN supports ADSL2+ too. With one particular 65dB downstream attenuation line, no improvement was seen, but better results were seen on a somewhat shorter, better line.
