Unplug modem and router. Plug modem in. Wait for block sync then plug in router.
Sorry, that was done when it first would not get a DSL connection.
The connection is there now, it is the lack of outbound from the computer that is the problem.
Here's what I have done that sems to have helped:
Power cycle the router.
Reset it to factory defaults.
Apply 1.31 firmware.
Power cycle the router.
Configure the router manually (no restore of settings).
Power cycle the modem and router.
I am able to send (SMTP, FTP, HTTP) from all systems at this point. The DSL connection is staying up as well.
More later. For now it seems that restoring the settings that I saved before updating the firmware may have caused a problem that was not solved except by applying new firmware.
