Sb5101 is complete it has internet but in every device says no internet

[AquaN30N]

Did my first 5101 and all the lights are on and I went to the Motorola page and everything seems to be good but the laptop icon has a triangle and the ps4 says DNS is not set.
What do I do? I have tried everything and nothing
Did I do something wrong in the process?
Or is it my devices?

I have the modern hooked up with the coax cable TWC.
I don't think it had haxorware on it

[AquaN30N]

It's the firmware OGT gave
Ok I'll try the Google DNS

I tried it but it's the same I can't get internet
It's SB5101-2.12.2.0-GA-01-707-NOSH

Kinda illegal ✌️
And I'm good thanks
I'm just frustrated with this modern
Why do you think might be the problem? Did I do something wrong in the process

ok so
I bought This modem
And a Usb black cat
I solderd the pins to the sb5101
And got the firmware to the modem then I went to 192.168.100.1
And everything is good with the modem it has internet
But I hook it up to my laptop and it keeps giving me no internet access

To be honest
I just want to get free internet but I don't know how
I thought by doing this I would be good to go
