IP addresses not renewing after resuming from Modern Standby

Hello,

I'm running Windows 11 Pro 24H2 build 26100.4061. Recently (for the past week or so), my PC is not renewing its IPv4 and IPv6 addresses after resuming from Modern Standby. It used to work fine before. Now, ipconfig /all shows only self-assigned IPs after resuming from Standby. If I do ipconfig /renew and ipconfig /renew6, the PC pulls IP addresses without issue from my DHCP server and everything works fine until the next Standby event.

All other devices on my LAN have no similar issue (Windows 10, MacOS, iOS, Linux). I don't know if this was introduced by a recent Windows update? What can I do to fix this?

Thanks!

Modern standby maintains your wifi connection by default.

Thanks. The settings described in that article only seem to apply to WiFi and have no effect on wired LAN connections (like mine).

Why do you need renewed IP's? Most people want to and need to keep the same no's for network reasons.

What I meant to say is that if the DHCP lease expires while the PC is in Standby, it will not renew automatically (with the same or different IP) when it wakes up. I have to renew the lease manually using ipconfig /renew and /renew6.

Check your services, make sure DHCP client is set to automatic and is running also the DNS Client
