Solution 4 – Set your IP address manually

When you connect to wireless network you’re usually given an IP address. This process is done by DHCP, but if there’s an issue with DHCP or with its configuration, you’ll get an IP configuration error. One workaround that is suggested by users is to assign an IP address for your device manually. To do that, follow these steps:
  1. Press Windows Key + X and choose Network Connections.
  2. Right click your wireless network and choose Properties from the menu.

We used settings that work for our configuration, but you might have to enter different data. In addition, you’ll have to enter the DNS server manually. In our example we used Google’s Public DNS, but you can also use 192.168.1.1 as your Preferred DNS server.
  5. After you’re done, click the OK button.
