Hi,

How to tweak the SNR on the Fritzbox with 6.06 firmware. I heard it has to be done via a phone handset on the phone port.

Cheers

Found it.

Yeah... Now my Fritz wont Sync.

Caveat and disclaimer:  Following these instructions is done ENTIRELY at your own risk.  Be aware that this firmware version has an issue where the line will appear "dead" if the incoming line is connected to the Fritz box when an SNR or INP configuration change is made, even if that's made via the web interface.  Do NOT omit step 2.

If you do manage to "kill" the line, try resetting SNRM target back to 0 (steps 2, 4, 5, 6), then disconnect the Fritz from the phone line and power it down for about 50 minutes.  Then reconnect it and power it back up, and wait a few minutes while it boots and resyncs.  This process worked for me, I can't guarantee it'll work for you.

Steps:

  1) Backups.  Backups.  Backups.
  2) Disconnect the incoming phone line from the Fritz box.  This is a precautionary step to prevent the line going "dead" when the Fritz initiates a resync after the config change.  (See post 2 on page 132.)
  3) Enable telnet on the Fritz by picking up a phone directly attached to it and dialing "#96*7*"
  4) Telnet to the Fritz box and log in.
  5) Execute the command 'ctlmgr_ctl w sar settings/DownstreamMarginOffset -30' to reduce downstream target SNRM by 3dB (i.e. 9dB target) or -60 for -6dB reduction (6dB target).
  6) Plug the incoming phone line back in.
  7) Enjoy your faster, possibly less stable, DSL line.

Semi related question: Are these newer versions stable/reliable without significant features cut yet? Or should i just keep sticking with the old trusty one?

this issue is why it was removed from the first post of the VDSL thread in the snap section.


be glad you recovered after 50 mins, when i had a wupsy doing that, took 3 techs to work out line card simple needed to be physically rebooted - it was odd that a naked VDSL line, didnt have a dialtone for the first tech... funny that..
