## Problem

I connected to the Cal Poly VPN using my T-Mobile Home Internet, but now I can’t access any Cal Poly websites or resources while other websites either load slowly or won’t connect at all.

## Solution

Adjust Network Settings on PC…

### Steps for Windows Devices 

1. **Log in to the PC** with an account that has **Admin Privileges on the device**.
2. Open **Settings**, then choose **Network & Internet/Advance Network Settings.**
3. Choose **Advanced Network Settings**.
4. Choose **PANGP Virtual Ethernet Adapter Secure** and **Edit More** adapter options.
5. Click on **Configure **in the** Adapter Properties **box.
6. Click on the **Advanced Tab**, then **MTU** and **change the value to 1300. **
7. **Close** out all windows, then **Restart the computer**.
8. **Connect to the VPN again**.  
*Connection should succeed and all websites and resources should be available. *

> ℹ️ **NOTE: **Users have reported degraded performance when connecting to the VPN with these new settings. This is a temporary workaround until PAN can provide a permanent solution.
