Boosting your line sync ADSL

In my last post on this topic I lamented that my line sync performance went down compared to what I got on Westnet to now Optus. Well today I found a handy nugget of information on Whirlpool Forums. Apparently you can adjust your Signal to Noise ratio sensitivity and have a degree of control on the line sync. The only problem is that you cant permanently save it into the router but at least you can squeeze a little bit more performance out of your router.

Mine is a Netcomm NB9W - though many routers with Broadcom chipsets will also be able to do this setting (like Dynalinks for example). Warning: I will not warrant that this works or wont damage your modem or phone line or providers DSLAM...you accept the risk ok??

Process:

1. Telnet into your router

2. Login to it

3. Check that it has an "ADSL" command and "Configure" property

3. Make the following setting - "adsl configure --snr XX" where XX is a number that you control the SNR ratio.

 

I initially set it quite high (200) and the sync dropped. So I knew it worked! I then started working down the number list eventually settling on 20. My line sync went up from 3.5MB to 4.7MB. So long as I dont reboot the router it will hold the setting - if the line drops out (which it hasnt so far) the router resync's at this setting.

Awesome!
