"Ethernet" doesn't have a valid IP configuration

Job ID: 33426734

Budget: $30 – $250 USD

Was working good for months and all the sudden 10 computers have the same message. I need help please.

Modem connected to router, to unmanaged tp link 10/100 switch then out to another smaller unmanaged tp link 10/100 switch. I have verified all connections are properly made. I have talked to Spectrum about modem and router settings. They claim that it is not them.

I have additional groups of computers coming off the same switch working properly. It is just isolated to these 10.
