Windows 10: ip4 no internet access but ip6 is connected

I'm trying to setup my home network, but ipv4 stopping working almost every evening and I don't know why.Do I need to send ipconfig page info here?I'm new here and appreciate any help.

:)

 

IP4 no DHCP addr; IP6 yes

WiFi. IP4 works if I do the assignment. If I enable IP6, then an IP6 addr does come.

 

"No Internet Access" on Ethernet and Wireless - Windows 10

Steps taken to resolve:

• Downloaded from Realtek and installed Windows 10 driver for Realtek PCIe FE Family device
• reset winsock and ip4 and ip6.
• reset DNS cache
• forced media connection by changing ip4 to fixed ip address, gateway, and dns server. Able to ping other devices on network - including gateway, but could not connect to internet. Diagnose unable to find issue with connection.
  • "ipconfig /release" message is "no operation can be performed on (adapter name) while it has its media disconnected."
• when using DHCP, do not receive response from default gateway, so ipconfig has strange addresses. Diagnose returns:
  • "Ethernet" doesn't have a valid IP configuration.
• all other computers on network able to use DHCP for addresses.

trudging through topics on tech forum(s) to find other solutions. Need suggestions on resolution.

 

W10 can connect to wider internet but cannot access web pages

I have an odd issue with my W10 laptop linked to Sky broadband in the UK via wifi using a Sky router. The effect is that while I can actually access the internet (I can send and receive emails using Outlook and can connect to other machines using TeamViewer) I cannot access any web site (Google, BBC etc). There is no specific error message, merely that the access request timed out and a suggestion that it may be to do with proxy. I have tried the following:

1. Other systems (W10 and ios) can access web sites using the same Sky router (therefore probably not a router problem)
2. I have sent and received emails using Outlook, so the broadband connection is working (probably not a Sky problem)
3. I have tried two different browsers (Firefox and Edge), no connection (not a browser problem)
4. I am using Windows Defender and have:
   1. Made sure that Firefox is in the list of allowed systems in its Firewall, no connection after a reboot
   2. Turned off the Firewall and tried again - no connection

My next step will be to re-install Windows, but has anyone got any other suggestions? Could it be some sort of virus (I have carried out a complete virus check using Defender) So - any suggestions?
