Hello YNTCD22,
Well sb8200 is a cable modem , I understand after the outage you are unable to connect to internet
To check on internet , please connect the modem directly to computer (preferably windows) and check IPV4 address
(Tocheck IPV4 address please follow the below steps :
1.Press windows and letter R key together , you will see a RUN command , type in “CMD “ on the Open bar , after that Press OK .
2.It will take you to a black screen over there you will see a cursor and type in” IPCONFIG” (without any space) and press enter key. . It will show you the IPV4 address
If modem provides IPV4 address as 192.168.100. (1 to 254) please activate the modem to obtain public IP address .from Internet Service Provider in order to connect to internet
The lights on the modem are good but on the Send it shows green means the Upstream channel is connected in DOCSIS 3.0 mode.
Kindly activate the modem with Internet Service Provider for Upstream channel in DOCSIS 3.1 mode in order to get the lights as before
Power: Green/ Receive: Blue/Send :Green and Online: Green
