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