Billion 7300G secret menu (less dropouts)
I seem to have a speed / reliability tradeoff with my Billion 7300G ADSL modem.
If I enable ADSL2+, the internet drops out many times a day.
If I enable only ADSL2, then I get slightly slower speeds (I’m quite far from the exchange), and dropouts happen every few days.
I then stumbled upon a “secret” menu:
http://{modem IP address}/iptv.asp
The “noise margin” drop down list gives you options of: Normal, IPTV, Maximum line rate, test lab 18, IPTV2, Others
Its currently set to “others”
I try a few settings, and these are the results:
Normal: 4093 kbps, noise margin (downstream): 7.2db
Maximum line rate: 4594 kbps, noise margin (downstream): 6.3db
test lab 18: 4775 kbps, noise margin (downstream): 6.1db
others: 4824 kbps, noise margin (downstream): 5.2db
This explains why many 5200G owners say its a very fast modem, but it works best if you are close to the exchange.
As the speed increases, the noise margin decreases and (I assume), the chances of a dropout increase due to changes in line characteristics.
So I decide to move from “others” to “maximum line rate”, and also change from ADSL2 to ADSL2+ (although I haven’t noticed any difference between ADSL2 and 2+).
After a few days, it looks like the modem is much more stable… no dropouts at all… its worth it for a slight drop in speed!
ah..nice
I recently came across your blog and have been reading along.A very good information. Thanks for sharing. I like this topic as I am also interested anything related to computer, internet and software. Keep on posting.
Regard
thanks for the info. I never knew that page existed either. huh!
I’m on ADSL1 sadly so I’ve tried the same settings you mentioned to see if this removes the line noise caused by the modem. No progress so far but I refuse to replace my third modem to fix this issue!
Thanks again. 🙂
thanks, tried this and from a few tweaks
from 5779/1023 kbps
to 1023 / 6710 kbps
