8/2/04 STILL SLOW:(

lo all i as u can see in my last threads that ive posted the problems ive been having. Everything is slow still all major work has been done on the exchange were i live and im still experiencing problems such as slow downstream and terrable speed test results which said that my download speed is only 50k a sec and sometimes 16 k sec on my one meg line when it should be 100+k. Ive posted three tickets already and plus net have tested my line and their results showed that my ADSL is ok. But the thing is pluset im still experiencing problems and want this sorted out ASAP beacause im realy geting annoyed with this now (no disrespect). I had these problems since installation and ive tried tweaks and everything posting tickets and non of it has helped. Also all maintainence work has been done on my exchange and the problem still orcurrs.

The unofficial line here is that "ADSL is what it is".

A cheap non-robust method of creatign a inter-network connection, using a single copper pare.

There is only so much PlusNet can help you with, and/or BT.

A few questions:

1: Did BT some to your premesis and do a speed test with there own equipment?

1a: Did it work ok?

If yes, then you are looking at a possible issue with youtr own equipment, be it PC or connection hardware

If no, then I am pretty sure BT would have never left it at that.

2: You are aware that because of the technology, you should never expect full speeds?

3: As above, but for contention?

Ideally if you can borrow a laptop off a friend and test your
line back to master socket, it would then rule out your own set up as faulty.
Could you take this tweak test
and post the results.

Uh? Your "advertized speed" is set at 122kBITS/s??
I don't know if it'd make any difference to the results.

Can't comment why your 1Mb behaves so irratically and below par, except there still being aproblem with your exchange or exchange capacity.
My recomendations would be reduce MTU to 1478 and increase RWIN to 32516.
Others will have different ideas. Tweaking is a little bit of a black art.

That isn't a bad result apart from a small amount of
packet loss.
Are you saying that you get poor results all the time
or just some periods ?
What speeds do you get on ADSLguide Speedtest
could you post some results.
Run through the MTU tweak topic and change your MTU to 1478 (MTURAS) and RWIN to
31636 . Retake the tests and see if you get any improvements.
The speedtouch modem works best with its own supplied filter so
ensure its connected or try swapping it over.

Downlaod DrTCP from
http://www.dslreports.com/drtcp

Run it and change the relative bits.
In the adapter settings, if you are using a USB modem, choose the "Microsoft TV/Video connection" (this is actually the USB) and change the MTU & RWIN settings.
If you are using a router, choose your network card and change the settings.

Dont forget to save the changes and restart the machine.

Microsoft TV/Video connection will actualy be a Firewire connection in most systems.

Most USB modems requires that only the RAS MTU be changed.

Hmm, never thought of that, USB or Firewire as the TV/Video connection.
In a system with USB and Firewire (which I havn't bothered getting), what would show up for USB ?Huh

The NIC list will only show registered network adapters and not modems.

Firewire registers as a network atapter in some cases (not all, depends on the firewire driver).

USB modems that register as network adapters will show up correctly in the list.

Those that have proprienty drivers, or that register as modems (don't always shwo up in the modem list) use the value from RAS MTU.
