This may indicate a modem or related hardware device failure, but some driver issues and/or software incompatibilities can also cause this error.
If you confirm the hardware is defective, replace or repair the defective item.
Often the fastest way to confirm defective hardware is to replace it with a known good item, if available.
Check if a newer version of the software is available, and if so, download and install the update.
