USB ADSL connection very slow on Linux (but fast on Windows)

I have Red Hat 9 running very nicely on a P3 450. I have just installed the
Alcatel Speedtouch 330 USB ADSL modem and am finding that my connection is
incredibly slow. According to the speed test on adslguide.org.uk it is running
at 56k dialup speed

When I plug the modem into my wife's Win XP machine I get the full 576 kbit/s
speed and everything runs lovely. This is connecting to Demon Internet in the
UK.

In my messages log I get the line:

modem_run: ADSL line is up (576 kbit/s down | 288 kbit/s up)

so it looks like the modem is connecting at the right speed.

Also in the messages log I am getting hundreds of messages stating:

pppoa3[1957]: CRC error in an AAL5 frame
last message repeated 53 times

Am I right in thinking that this is the problem? It sounds like the packets are
being corrupted and having to be resent thereby causing the true throughput to
drop.

Although I am quite PC savvy I don't have much experience of Linux so I would be
grateful for any help I can get in sorting this out.

Many thanks in advance,

Mike
