Hi,
wan public dynamic up address is visible, then slipping off the Wan interface to 0.0.0.0. Why?
then, laptop locks up, then no WiFi SsID is visible, no Ethernet interface detected on laptop, but surrounding 3rd party office SSIds are visible.
these symptoms are recent , July, 2021, had to to TZ 205 wireless firewall, v5.9 os, for many years - never had problems.
Always Reboot , in past, the cable modem from Spectrum isp, & TZ firewall, 1x month, for regular maintenance.
. Already read 1 SonicWall knowledge base article on WAN public ip, not renewing, but article does not solve, why public ip slips and reverts to 0.0.0.0.
I did replace cable modem, but issue happened 1 x , again, in July.
thank you.

The TZ205 has been End of Life for over a year. Time for an upgrade.
Thank you for quick reply. I was aware of product end of life cycle, however, your answer does not explain ip address slip. That is, is the carrier, isp or firewall at fault? Or slip is something else?
disclosure: I emailed SonicWall customer service about replacement recommendations.
thank you
Hi @PFTS,
Please try the suggestions as per below KB articles.
Look to see if the firewall runs on its latest firmware version.
Hope this helps.

Will review.
regarding allowing Ping on the wan interface (wan up address 1st kB article), how to identify and contain/program the ips from the Spectrum isp? That is, to allow pinging, only from them, but close off, from the world.
Thank you.
Thank you.
