Many times WIFI issues can be solved with a few simple fixes. Some of the most common example are below:

	Symptom	What to do
1	Desired Wireless network is not detected by my computer	If you do not see any wireless networks. See if your computer has a switch that can turn off the WIFI adapter, make sure it is in the on position. If other SSIDs are visible, but not the desired SSID Please Call IT (x3199)
2	Your computer is connected to ACC SSID, but you receive an error or are unable to browse the internet. (This may happen to a computer that was previously registered to our system)	Check your IP address (Directions for both PC and Mac are below) Make sure IP address is within the scope for the campus you are at (Correct values listed below) Try to release and renew IP (Directions Below) If you are still unable to properly connect Please Call IT (x3199)
3	You are connected to ACC SSID, but are not being redirected to the login page in your browser	Attempt to navigate to another web page, such as Google or yahoo. Sometimes this can get the login to redirect. Check IP address and DNS setting (Directions for PC and Mac Below) Set you Network Adapter to obtain an IP address automatically (Directions below).
4	Cannot pass authentication (Students and Employees)	Ensure password is correct and has not expired Try to login to a lab computer with the same credentials. If you cannot login your account may be locked out Call IT (x3199) If you are able to login probably trying to register a 6^th device (You can only have 5 registered devices) Call IT (x3199)
5	Cannot access the network even though I was approved by the front desk agent (Guest Access)	Retype in provided credentials at the login screen (email address and generated password) If you still cannot login Call IT (x3199)

How to check IP address and DNS setting

On a Windows 10 PC:

Go to “Start” > “Windows System” > Command prompt.
- Double click to select “Command Prompt

A new window will open

Type: ipconfig /all (Note the space between "ipconfig" and "/all")
- Press “Enter”

Scroll Down and Look for “Wireless Lan adapter Network Connection”
- Take note of the IPv4 Address and the DNS Address

The correct values for your IPv4 Address and DNS Address are as follows:

Main

Parker

Castle Rock

IPv4 Address

10.110.xxx.yyy

172.16.xxx.yyy

192.168.255.xxx

DNS (at least one of the listed is present)

10.105.248.2

10.105.248.3

10.105.248.4

10.105.248.2

10.105.248.3

10.105.248.4

10.105.248.2

10.105.248.3

10.105.248.4

If any of the values appear to be incorrect, you need to release and renew the addresses.

At the same command prompt type:
- ipconfig /release (Note the space between "ipconfig" and "/release")
  - Press “Enter”
- Then type: ipconfig /renew (Note the space between "ipconfig" and "/renew")
  - Press “Enter”
Check the IP and DNS address using the steps from before.
- If the values are still incorrect, it is possible the user entered them manually. The user will need to change their Network Adapter properties to: “obtain an IP address automatically” and “obtain DNS server address automatically” (Directions below)
