My router is working perfectly, and all other computers use automatic DHCP to get an IPS address (all hard wired--no wireless). This one laptop network connection preserved getting stuck "identifying" the network, until I set a static IP in the ipv4 config properties (win7). Endpoint site firewall policy settings for Windows press macOS in Microsoft Intune
Reasons would that resolve the issue?
ipconfig /release
theipconfig /renew
prior you did the static IP? And did you see reboot your DHCP server/router? I've had it where certain devices will connect just good, whilst other won't be able to. A reboot of the router always worked and a reboot of that computer never hurt.
