That's right, my current ADSL is a little too flaky to count on. For
example, it's only delivering 27k cps today with lots of dropped packets. It
was also down for a full day two weeks ago.

Not sure this would be suitable plus no solution to sharing printers or
other devices.

It sounds like this would work, but would be limited as far as adding other
computers to the network, which is a real possibility.

I already have a dial-up backup, but this ties up the phone line. I had to
give up my second phone line when I moved into this condo and it would be a
hassle to have another one installed here. I would prefer two broadband
connections.

Thanks for the input.
