Default COM Ports not showing in Device Manager


I'm having trouble accessing the internet. My cable modem is fine. When I
use troubleshooting it shows the com port not connected. When I go to Device
Manager under ports it only shows the LPT1 port and no com ports.

Did my com port die? If so can it be resurrected? How do I do this?

When an internet page does load (after many seconds) it will show no server
found but when I click refresh the page appears.

I'm not real computer literate so please be as specific as possible. THANK
YOU!

Are you sure that you have a cable modem? I've never heard of a
cable modem that connects via the legacy serial (COM) ports. However,
the old telephone dial-up modems do still use COM ports. Cable modems
usually connect to the PC by way of a USB port or an Ethernet
connection.

Exactly what brand/model cable modem do you have, and how is it
physically connected to the PC?

Default Re: COM Ports not showing in Device Manager

It is connected at the back where it says 'network' so i guess that is an
ethernet connection. But when I try to troubleshoot it comes back and says
the com port is missing/not found.

The modem is a model 60678EU external cable modem.

I'm just trying to be able to connect. It seems that it is dropping my IP
address. But the cable company can ping to my computer and back. Still,
when I try to access an internet page through internet explorer it takes
forever and then says page not found but refreshing brings it up. Once I'm
on a site I can do OK until I have to go to another page (like hit the
continue button). Any ideas?

Thanks!

If you're connected via an Ethernet card, you needn't worry about
any legacy COM port settings. In fact, troubleshooting an Ethernet
connection shouldn't even test any COM ports. What make/model
Ethernet card do you have? How, precisely, are you getting to this
point?

You've still failed to mention the specific brand of cable modem
you're using. Is it the Ambit SlipStream 60678EU? If so, have you
followed the cable modem's manufacturer's troubleshooting guide(s)?

Your ISP should be able to walk you through configuring your NIC
and Cable Modem to properly communicate with their service. Can you
ping your ISP's servers? Have you configured your IP and DNS settings
per the instructions provided by the ISP?

When did you last check your computer for viruses? For adware?
