I just got Gigabit internet with Digital TV and Home Phone last weekend, and today (5 days later) I woke up in the morning to a locked up modem - white Hitron CODA-4582 with 33T3 firmware. The lights were on, and were either green or blue, with the one that looked like a computer flashing green (which I think may be normal). However, I could not access the GUI of the modem, and I had no internet access. The line was still active, as TV was still working, and home phone still seemed to be OK.
I waited a while, but internet access never came back, and I still couldn't access the modem either by wired Ethernet or by WiFi through Apple WiFi access points (configured as access points only, not routers) hardwired to a switch connected to the modem. (2.4 GHz WiFi on the modem is turned on, but I don't use it, since I have the Apple access points. 5G is turned off.)
So, I just power-cycled the modem and all was fine. IIRC, the icons lit up as before, complete with the flashing computer icon.
This is concerning, as my modem didn't even last a week before a lockup. Maybe it was just a random thing, but how best to troubleshoot this?
P.S. How do I change the handle name for my account? I just typed that in as a temporary thing, but didn't realize I couldn't change it later.
I'm glad we were able to assist you with the name change .
Seeing a loss of connectivity within your home network can certainly come as a shock for sure. Given the information provided thus far there isn't enough to indicate where exactly the issue lies but to troubleshoot it a bit further can you confirm for me if you tried bypassing your switch to connect a wired device to the modem before the reboot?
No it wasn’t a direct connection bypassing the switch. I only tried connecting via WiFi and via Ethernet through the switch.
After a modem power cycle all was fine. I did not power cycle either the WiFi access points or any of the switches. They remained on and now everything works fine through them to the modem. Next time I’ll try plugging into the modem directly. However, IIRC I couldn’t see the WiFi from the modem as a WiFi network option anymore when the internet was not working.
It's possible there may have been more than one issue that was restricting your ability to connect. Should it occur again though definitely let us know if a wired connection to the modem works prior to the reboot, with that we'll have a starting point .
