I can't give you the exact model number of the Westell DSL modem that caused the problem. Unfortunately, it is long gone. Just try substituting a different DSL modem to see if that resolves the issue.
If DSL modem substitution is not possible, try taking your computer to a location which has a different internet access (e.g., cable or FiOS). If you have no problem there and you continue to have a problem using the Westell DSL modem, it's your culprit.
