Can anyone advise which the best firmware for the Vigor 120 (v1) would be to handle variable line quality. The SNR downstream fluctuates by about 4dB and this is triggering the DSLAM to apply overly large margins to the line. I know that there are subtle differences in the ADSL driver versions and I am currently running the following.
Code:
Model Name : Vigor120
Firmware Version : 3.2.4.4
Build Date/Time : Aug 16 2010 11:14:51
ADSL Firmware Version : 332201_A Hardware: Annex A
CISCO have in the past offered "specialized" versions of their ADSL code to manage bad lines and I am wondering if DrayTek do the same.
This is the current "adsl status" for reference, if anyone is able to offer some suggestions. The line quality issue is a BT one and there is little I can do from my end, apart from graph it to use a a big stick if it should eventually fail altogether.
Code:
