I finally got internet connection by ignoring tech support suggestions and following my instinct that it was security related.  First I removed McCaffy and turned off the windows firewall.  Then I went through the ip configuration for the 6th time and finally got dhcp and my dns settings in tcp/ip to work and I got internet.  Turned firewall back on and plan to use Windows Defender.  I'll complete setup tomorrow after Windows updates are downloaded while I rest.
I connected my new one 2020, win 8 to our office network via ethernet cable and the following occurs:  broadband connects to router, but no internet access. I can reach our router and see the router setup and status screens, but no internet.  The rest of our office has perfect internet access. I tried calling support twice, and the folks abroad insist that they have to go through their hardware trouble shooting even though the network card obviously works.  I suggested that it was probably a windows security issue and they said to reinstall windows.  Very frustrating.  Any help out there?
My new Inspiron one 2020 will not connect to the internet via ethernet.
