Why do I have speed or connectivity issues?

If you are experiencing speed or connectivity issues, it is best to set a specific speed at half or full duplex in your settings.  You can set your network adapter to perform at a certain speed, but the device that the adapter is connected to (whether it is a router, switch, or computer) must also be able to perform at the same speed.

Note: You must log in as the local administrator before you continue.

To open Device Manager:

• Press Windows key + R.
• Type devmgmt.msc.
• Click OK.

1. Open the Networking adapters section.
2. Right-click the network adapter that you want to change and select Properties.
3. Click the Advanced tab.
4. Scroll down to Speed & Duplex. By default, it is set to Auto-Negotiate. Select any of the speeds that you see in the list.
5. Click OK and restart your computer.
