My ISP provides Arris TM3402A cable modems. Work great most of time, and get the 50M download speed I pay for. Recently though, have an issue were modem stops working with internet.
The ping loss rate to the local name server is generally 0 with occasional 1-10 drops.
Generally, those are fine, but then it will sometimes jump to 60% to 100% and internet becomes useless.
Can still access the cable modem on 192.168.100.1.
Have a script that sends 50 pings to the name server every 2 minutes.
If loss is less than 10% ignore it, but if higher report it with a sound.
Generally, if it goes higher than 50% the internet goes out, and next check goes higher, and eventually stays at 100%. Power cycling modem is only way to get it working again.
The web page doesn’t have a reboot option? Does have an advanced tab, but that requires a daily password?? So only pulling power to reset.
Then it is back to working? Had a surfboard modem, and recall it having a way to send a reboot command. But can find nothing for this one.
Has happened like 13 times over the past 2 days?
