How to increase AT&T gateway to PC ethernet speed

[KPTx]

AT&T fios to gateway speed always 1000MBPS.  Using motherboard ethernet connection, gateway always 220 - 240 MBPS.  Can I increase speed, maybe with USB-C ethernet adapter?  Serial number.

Hi @KPTx, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
It sounds like your HP Pavilion Desktop is experiencing a bottleneck with its onboard Ethernet connection, which is limiting your speed to 220–240 Mbps despite your AT&T gateway providing 1000 Mbps.

Steps to Improve Speed:

Check Current Ethernet Port Speed

• Your desktop’s motherboard may have a Gigabit Ethernet (1 Gbps) port, but it could be negotiating at a lower speed (100 Mbps) due to:
  • A bad or old Ethernet cable (ensure it's at least Cat 5e or Cat 6).
  • The network adapter being set to 100 Mbps instead of 1 Gbps.
  • A driver or firmware issue.

Verify Network Speed Settings

• Press Win + X → Select Device Manager.
• Expand Network Adapters, right-click your Ethernet adapter, and select Properties.
• Under the Advanced tab, look for Speed & Duplex and ensure it's set to 1.0 Gbps Full Duplex.

Try a Different Ethernet Cable

• Use a Cat 6 or Cat 7 Ethernet cable to rule out cable issues.

Update Ethernet Drivers & BIOS

• Visit HP’s support page for your PC model and update your network adapter drivers and BIOS.

Test with a USB-C to Ethernet Adapter

• If your PC has USB 3.0 or USB-C, a USB-C to Gigabit Ethernet adapter (or USB 3.0 to Gigabit Ethernet adapter) can bypass the onboard Ethernet and may give you full 1000 Mbps speeds.

Check the AT&T Gateway

• Ensure the LAN port you're using on the AT&T gateway is indeed Gigabit-capable and not limited to 100 Mbps.
• Some gateways have specific QoS (Quality of Service) settings that could be limiting your desktop’s speed.
   

I hope this helps. 

Take care and have a good day.
