Cannot connect to internet with desktop

[StopNancy]

Tried connecting to EarthLink internet and computer says internet available but there’s no list to choose from. When I attempt to create a connection it says modem problem 681. Not sure how to update network adapter if that’s the issue. I was able to connect to the internet before I switched to EarthLink. EarthLink is unable to help me.

Hi:

The product specs for your PC indicate that it only came with wired networking capability.

If you added a wireless network adapter, you would have to see if the manufacturer of the device has updated drivers for it.
