If you are getting various errors like ‘Limited connectivity‘, ‘Wifi doesn’t have a valid IP configuration‘ or ‘Unidentified network‘ but your Wireless Key and SSIDs are never changed then it might happen that you or someone attempted to change adapter settings on your PC or Laptop.
Some routers and/or ISP, needs that the connecting adapter or say system must have IP address in same IP block and Subnet as of router or ISP. This is kind of security and networking feature, but is a pain area when you change the router or ISP.
On Windows 10, there might be some other reasons but if everything else is ok, then all stake are on your Wireless adapter IP settings. It can be manual or automatic depending on your service provider. So, let’s see how you can change Wifi adapter IP on Windows 10 to Manual or Automatic IP settings. This guide also works on Windows 7, and 8.
Change Wifi Adapter IP on Windows 10
Setting Wifi Adapter to Automatic settings
I am taking example of Wifi network of TP-Link MR3020 portable USB router here for all methods and ways.
If you were using a router which needs specific IPs to be accessed and now changed the router, you might need to set the settings to Automatic IP. This works well with most of the wireless routers, ISP and Ethernet ports.
Click on Start Menu on your Windows 10, and then start typing ‘wifi‘. You will see the setting ‘Change Wi-Fi Settings‘ in best results of search. Select it or simply hit Enter.
On next screen, you will see the network you are connected to and other details. Nothing might show up if you are not connected to any network. However, there are some ‘Related settings‘ present on side of this screen. Select ‘Change Adapter options‘ from that list. It will bring you to a screen where all adapter present on your laptop and available with Windows 10 will be shown.
Right click on your Wifi Adapater and select Properties.
Now, navigate to ‘Internet Protocol Version 4 (TCP/IPv4)‘ and after selecting it, click on Properties.
Set everything to automatic settings as shown below,
You are done. You should now be able to connect the router and network.
Setting Wifi Adapter to Manual IP and Subnet Mask
For this, you will first need to know the IP address of your router and/or ISP (Internet Service Provider). Most of the router works when you set any address within the IP block. So, if your router admin portal login IP address is ‘192.168.0.1’ then setting your IP to something like ‘192.168.0.2’ would mean that you are on same network.
Like in automatic method, type ‘wifi‘ in Start Menu on your Windows 10. Then select ‘Change Wi-Fi Settings‘.
On next dialog box, under ‘Related settings‘, click on ‘Change Adapter options‘ from that list. Screenshot and details are given in first section above. Find, your Wifi adapter and then go to it’s properties as told before.
Go to properties of ‘Internet Protocol Version 4 (TCP/IPv4)’.
Now, change the IP address and Subnet mask as per your ISP or router IP block. Here, I entered ‘192.168.0.2’ which belongs to same ‘192.168.0.x’ IP block. For most of the IP, subnet mask will be automatically set.
You can also enter a static IP provided by your Internet provider here. Remember that, your router will also need to be configured to accept the connection from ISP and adapter. As that is a tedious job, it’s always easy and better to use static IP for router config and then setting internal dedicated IP for adapter.
Hit OK and you are done. Now, you will be able to connect to your router and Wireless network.

Sometimes, even after changing this, things may not work as Windows didn’t actually took and applied those changes. Also, it might be necessary to release the adapter and renew the IPs from router or providers in many cases. You can simply use below steps to get it done.
Click on Start Menu and type ‘cmd’. Select ‘Command Prompt’ to pull out our oldest and reliable rescue friend – MS DOS prompt.
To release all adapter from current connection and state use below commands,
Then, issue the below to renew IP address from router or internet provider,
This should do the trick. If not, then try restarting the system once to flush all old settings out.
