Thanks for the reply - I think you may have solved my problem.
Today I tried speedtouch v.1 with another PC I have around, this one with a Via 
chipset instead of the old intel triton PIIX3. I figured this was a good chance at 
proving or eliminating the usb theory since it's an OHCI chipset instead of UHCI.

Night and day difference! I was able to download large files over ftp at 150KBs 
without loss of connection. So I ran out to the store to get a USB adapter (been 
searching w/o luck for old ng posts on which adapters are reliably supported by Linux) 
Bought a SIIG 2port usb board since it was the only option there aside from completely 
House-Brand models and the SIIG box stated full USB1.1 + PCI spec compliance. This 
board uses the USB OHCI driver like my via mvp3 socket 7 board.
Put this board into my old p166 router and have downloaded over a gig at high speeds 
without any interruptions. this must be a very important contributing factor to my 
adsl problems if not the whole thing itself. Before the USB adapter this kind of 
downloading would have derailed the connection 10 times already, probably many more 
times coonsidering I've downloaded, in addition to every Mozilla binary build of 
moz-v1.0rc1,. a 650 MB iso image and several 2.4.x kernel tarballs. Yesterday 
downloading a mere 30MB rpm of the 2.4 kernel was out of the question - just too many 
errors arising from too many restarts.

Thanks for the news about USB chipset problems. I was on course to rip out the phone 
wiring and put in an external dsl/pots splitter (ordered one it's en route guess I'll 
install it for fun) after that I would have broken down and bought a dsl to ethernet 
bridge from my ISP. That would have cost me more than money, but some pride too. 

thanks again,
~/j.
