SBG3300

Hi all

Got my 3300 at the weekend speeds  definitly appear quicker on BT wholesale,

but I am concerned by my interleaving depth, Just wondered if anybody knows

how  I may be able to reduce it.

The only way to get your interleave depth improved is to leave the modem constantly connected and pray that DLM sees your connection is more stable, then if this happens, it should slowly release the constraints it has placed on your line.

Note that this could take a while; as far as I am aware, DLM needs to see a stable line for around 10 days before it starts to relent and then it could be even longer after that, before you see anything noticable with regards to latency, etc as DLM acts in "steps", depending on where it's current position is on your line.

Re: SBG3300

Thanks I guess I'll have to wait and see if this router makes my line more stable,

 

Thanks again.
