how to uses these commands to reduce delay as much as possible to multiplayer connection

[Weaver]

Unfortunately I’m not familiar with this modem. If you succeed in getting rid of interleave, then you risk making the line unreliable. Can you see what the interleave depth is currently.

[esso]

currently my interleave depth is 32

[Alex Atkin UK]

currently my interleave depth is 32

You sure that's depth and not block?  Does it tell you the delay?

[esso]

it's 8ms

[Alex Atkin UK]

Ah so its definitely interleaved then.  Not sure what to suggest as its been a long time since I used ADSL.

At a guess I'd think forcing the minimum SNRm to be higher so you sync at a lower speed then wait and hope DLM switches you to fastpath.

[Weaver]

At the risk of telling you something you already know, the interleave setting is determined during negotiation with the modem at the exchange end and either BT / OR dynamic line management or the ISP is what controls this.

With my ISP I can change the interleave setting myself:



You should ask your ISP. If they don’t know what you’re talking about, then change ISP! :-)
