Just to follow up on my router problem:

That sounds like experience speaking. I think I'm stuck with 10Mbps,
which is what I've had all along by forcing 10Mbps Full with ethtool
(after someone here pointed me to it, tnx.)

Can of worms, eh, Jim? Dead-chicken cure, eh? Did that. Yes, I
pulled the power plug. Card and DI-713P still twiddle infinitely when
plugged together, no connection. Resetting to 10BaseT-FD makes a

Yeah, well, comparable routers seem to start at $60. Then I need a
($40?) USB->Centronics converter cable for my perfectly good laser
printer. Plus setup time and re-learning stuff I already know but
with different knobs and levers. I can live with a 10Mbps LAN.

Probably. You'd think there'd be a bunch of net reports or questions
about the problem, though, since there are numerous (old) posts
praising that model.

Just have to go buy new electronic doo-doo to keep my old gear
running. No, just to *diagnose* it. I'll just buy a new router when
this one finally dies or I truly need better speed or more features.
Maybe when Eastlink finally gets the wireless tower for this area
I was hoping for a magic incantation. F'rgzample, this DELL P4 (now
nearly all customized to suit me) would consistently crash X when
doing a console switch from console n (0<n<7) back to X in console 7.
Seems there is a smallish family of DELLs with a BIOS bug such that
BIOS is never correctly notified about X's video RAM
allocation. [Arcane details elided.] A guy in Germany wrote a little
(OSS) program which can be run from /etc/rc.d/rc.local at boot which
patches whatever is broken. Magic incantation, all fixed.
Not so lucky with the router.
Thanks all for suggestions, pointers and enlightening discussion,
