Which is better – USB, PCI or Ethernet modems?
These days you’d be hard pressed to find an ADSL modem that is just a modem so in many cases if you do need a basic bridged modem you’ll need to reconfigure a modem/router product to do the job. USB & PCI modems sometimes have driver issues between operating systems and will also use resources on your PC but other than that they’re cheap as chips and may be all you need if you only have one PC.
