I look after a 2860 that's dropping the ADSL line several times a day. Is there any documentation that explains the benefits of each DSL modem code or are you supposed to try each one and find out for yourself?

It seems you have to try to see which one is better for your line


There are also 2 different firmware at UK download pages each one has its own modem code & if you want there are 3 more firmwares at main Taiwan each one again has different modem codes
