excerpt: "Here's a tutorial on configuring your iPhone, iPhone 3G/3GS or iPod Touch to connect to NUS Wireless. We use the NUS SSID rather than NUSOPEN, since NUS is PEAP-protected and much faster. Note an iOS 4 bug affects this too."

Here is a tutorial on how to configure your iPhone, iPhone 3G, iPhone 3GS, iPod Touch, or iPod Touch (2nd Gen) to connect to the NUS Wireless network. We will be using NUS WLAN SSID “NUS” instead of “NUSOPEN”, as “NUS” is protected by [PEAP](https://en.wikipedia.org/wiki/Protected_Extensible_Authentication_Protocol) and it is much faster.

**\*UPDATE 2\*** There is a bug in iOS4 which cause .mobileconfig files not recognized by Safari. For more details, read here. To overcome this issue:

1. Using your computer, go to https://lesterchan.net/nus/iphone/
2. Key in your NUSNET UserID and click Generate
3. Your browser should prompt you to download the NUS.mobileconfig file
4. Once you have downloaded the file, email the file to yourself
5. Using Mail.app in your iOS, open up the email which contains the NUS.mobileconfig attachement
6. You should now be able to install the NUS.mobileconfig profile

**\*UPDATE\*** It is now working with iOS 3.0.  
**Instructions**

1. Launch **Safari** in your iPhone/iPod Touch

**Notes**

- **At Step 18**, you may need to re-try **Step 14 to 17** if it takes more than **1 minute** to connect.
- **At Step 20**, you may need to re-try **Step 14 to 20** if nothing happens when you click **Accept**.
- If you are going to reference this tutorial anywhere, please credit it to me. I spent a lot of time on figuring out how to configure my iPhone 3G to connect to NUS Wireless network and I have put together this tutorial to make life easier for all NUS students.

**Privacy**

- The generator **DOES NOT** save your NUSNET UserID on this server.
- At Step 10, when asked to key in your password, it is iPhone authenticating with NUS and **NOT** with this server.
- In short, you can rest assured that **NONE** of your information is saved on this server.
