I cannot go on-line after connecting the Suddenlink cable fom the external modum to my iMac G5. The same cable is currently providing servive to my HP Laptop, withput problems. How do I configure the iMac?
just because the modem works with the hp - you cant assume that it will work with the imac.
you need to confirm that the specific modem is supported with the version of macos you are using.
for example when i got my imac g5 als back in 2005 i used an existing work laptop intel adsl modem.
it would work fine for an hour or 2 and the the mac would blue screen with the fans running full tilt.
looking on the intel site told me the modem didnt support tiger.
I ended up buying a low cost router - provides a lot more flexibility so if you can afford that it's probably well worth it.
