How to Fix a Wireless DNS Problem
DNS stands for Domain Name Server, representing the server to which your computer connects when making requests over the Internet. The DNS server translates your web requests into an IP format that is understandable by other computers and back again, enabling you to contact and communicate with other computers over your wireless connection. When your wireless DNS server begins to act up, you can reset the connection to fix the problem.
Open "Start" and select "Run."
Type in "cmd" and press "Enter."
Type in "ipconfig /release" and press "Enter."
Type "ipconfig /renew" and press "Enter." This will reset your connection to the DNS.
