Hi,
I`ve had several occurences where computers (andéor routers) hooked on the LAN side of the SPA122 are unable to access the Internet after some time. The FXS lines continue to operate normally so phone service is not impacted.
On one occasion, the ATA was directly connected to a cable modem and a Cisco WRVS4400N was connected to the LAN port of the ATA. The WAN side of the Cisco Router no longer had an IP which makes me to believe there is an issue with DNS in the ATA.
I am running firmware 1.3.1 and had the condition on two occasions with this setup
I turned on debug and noticed this in my syslog server:
Jul 21 18:44:37 ATA01 mDNSResponder: ERROR: getOptRdata - unknown opt 4
I wonder if this would give someone a clue as to what happens.
Thanks,
Benoit
