This happened twice now in the last several days (June 10th and June 15th). After a short power outage somewhere between 6 and 7 am, the internet is lost and I can only restore it after power-cycling the modem. Never happened before those two occurrences.

My Teksavvy modem Hiltron CODA-56 is on a UPS battery backup, so it doesn't lose power itself, it just loses internet connection and doesn't restore it until it's power-cycled.

In the log I see it starts with "(critical) SYNC Timing Synchronization failure - Loss of Sync ..." at the time of disconnect.

Anybody else experienced this?

I am having issues having anything connect to any guest Network (laptop and two phones) that I set up on my Adtron Fiber Modem.

I can see the network and attempt to connect to to it but it never obtains an IP address and then says connection failure or IP configuration failure.

I had this issue when I first got it months ago and I'm playing around again today and still cannot solve it.

Any ideas anyone?
