Got new modem and my laptop won't connect anymore

Hello! We have around 3 computers and 2 laptops in our house, and we just changed our modem to a new one (U-verse), and all our computers and laptops work fine except one now. It does "connect" but it says connceted to a unidentified network. We have tried reseting the modem/making sure it auto obtains IP/DNS.
Not sure if these help but here are some screenshots

Any help would be loved :( Can post more information if needed. Thanks!
 
Try this in a command prompt (elevated, run as administrator)

netsh winsock reset

Restart and observe.

Tried a static IP?
