Windows 10: IP Address must be manually released/renewed every time Windows is restarted.

Hello all,


I am having an issue with network connectivity on my laptop. Every time I restart my Windows OS, in order to get an internet connection I must manually release and renew my IP address via the command prompt. This happens with both Wired and wireless connections, and happens on different internet connections as well, meaning I still have to release and renew my IP address via the command prompt whether I am using my internet at home, school, or anywhere else. All connections I use are set to "Obtain IP Automatically" under IP Protocol 4, so that's not the issue. This started happening after a major Windows 10 update a few months back.


Thanks for the assistance!

Side effects of releasing/renewing IP addresses?


There is a fairly well know security package that is causing some users problems on Win 10 AU - browser connections get blocked. (Other TCP/IP connectivity is unaffected - just browsers.) A user of the product found that releasing and renewing DHCP-provided IP address - i.e., doing "ipconfig /release" followed by ipconfig /renew"" temporarily fixes the problem. Can someone explain to me what doing a release/renew does to Windows such that a program - even a program with deeply embedded hooks - would even know this has happened.

Obviously the computer will get a new IP address from DHCP. (Which, for many DHCP servers, will likely be the same as the old one.) If it gets a new address, will this make Windows switch it's network profile from "Private" to "Guest or Public"? (I know the security package will see that.)

And a few more questions relating to /release and /renew but unrelated to the problem:
I see there are IPv6 versions of /release and /renew. Does that mean that /release and /renew apply to only IPv4 addresses, or do those commands apply to both IPv4 and IPv6? If only IPv4, is there a way to release and renew all addresses? The DHCP server supplied a list of DNS servers as part of the DHCP handshake. Does the release and renew process also renew the list of DNS servers? If so, is there the same division of IPv4 and IPv6?

 

IP Address Renew

Hello,

Just recently my computer stopped automatically renewing my IP address. Every time I try to access a different router, I have to release and renew my IP address manually. I am wondering if there is any way I can fix this. I checked the properties on my
wireless adapter, but it is already set to obtain the IP address automatically.

 

Need to reset/renew my IP address

• Click Start->Run, type cmd and press Enter.
• Type ipconfig /release at the prompt window, press Enter, it will release the current IP configuration.
• Type ipconfig /renew at the prompt window, press Enter, wait for a while, the DHCP server will assign a new IP address for your computer.
