I'm having a issue with my DSL which is proving a royal pain. My
connection does not drop (no speed renegociation occurs), but every so
often (there seems to be no pattern) I cannot send data. I did a
lengthy series of pings to several internet hosts and the issue shows
as a bunch of ping timeouts as illustrated below:

According to telecom my line appears to be fine. I have had a issue
just like this in the past that I traced to the filter, which when
replaced eliminated the problem, and so when the problem reappeared
the first thing I did was unplug my phone and remove the filter. The
problem this time persisted however. At this point there is no other
devices on the phone line apart from the DSL modem.

I have a ASUS AAM6000EV external DSL router, and it has been a very
reliable router. I am on a Jetstream 2 MB plan, and my typical connect
using g.dmt is 7.3 Mbit down, 320 kbit up. The 320 I understand is set
by Telecom. I have tried using g.lite which can be more resistant to
line noise, but that was no help either.

The problem appears to be on the upstream side of the connection, as I
have noticed several times (such as when playing online games) that
when it happens data will continue to come in, just the upstream side
won't send.

I then did some research and a suggestion offered (here:
http://www.nzgames.com/forums/showthread.php?s=&threadid=50223&highlight=bsp%2A
) was to go into the modems console, into the bsp menu and increase
the gain which defaults to 4. The suggestion was to increase it by 10
then monitor the getes command output for errors. I tried this and it
appeared to help some, but errors were still occurring, so I increased
by a further 10... rinse, repeat. I tried 34 and was getting nervious
Telecom may throw a fit at me for melting their exchange :) (so i've
returned it to 4).

At 34, I am still getting the problem and the getes command is
returning the following count on errors after about 15 minutes

Near-end ES=127 Far-end ES=36

In this time there was 2 bursts of "Request timed out" messages from
the pings I was conducting at the same time.

Can anyone offer guidance on whether this course of action is safe
and/or wise, and if you have any other ideas.

Lance.
