AT&T Internet - Optimize Wi-Fi Performance and Network Speed

Purpose

Use this procedure when a customer wants to improve Wi-Fi coverage, increase internet speeds, reduce network congestion, or optimize home network performance.

Customer Symptoms

Customer reports:

• Slow Wi-Fi speeds
• Weak Wi-Fi signal
• Poor coverage in certain rooms
• Frequent buffering
• Lag during gaming
• Smart devices disconnecting
• Network congestion
• Slow performance with multiple devices
• Inconsistent internet speeds

Understanding Wi-Fi Performance

Wi-Fi performance can be affected by:

• Gateway placement
• Building layout
• Number of connected devices
• Device capabilities
• Signal interference
• Outdated hardware
• Outdated software and drivers

Optimizing these factors can improve network performance and coverage.

Optimize Gateway Placement

For best performance:

1. Place the gateway in a central location.
2. Position the gateway upright.
3. Place it on an elevated surface such as a shelf or desk.
4. Keep the front of the gateway facing the primary usage area.
5. Ensure the gateway is not blocked by furniture or walls.

Avoid Placement Near

• Cordless phones
• Bluetooth devices
• Microwave ovens
• Large metal objects
• Heat sources
• Moisture
• Excessive dust
• Extremely cold environments

Improve Coverage with Extenders

If signal strength remains weak:

1. Install a compatible Wi-Fi extender.
2. Position the extender between the gateway and weak coverage area.
3. Verify devices connect to the stronger signal.

Use Wired Connections

Direct Ethernet connections provide the fastest and most reliable performance.

Recommended devices for wired connections:

• Desktop computers
• Gaming consoles
• Smart TVs
• Printers
• Blu-ray players
• Streaming devices

Benefits

• Faster speeds
• Lower latency
• Reduced Wi-Fi congestion
• More bandwidth available for wireless devices

Reduce Network Congestion

Too many active devices can reduce Wi-Fi performance.

To improve performance:

1. Disconnect devices not currently in use.
2. Close background applications.
3. Move stationary devices to Ethernet connections.
4. Remove unused devices from the network.

Configure Wi-Fi Broadcast Mode

Wi-Fi standards include:

• 802.11b
• 802.11g
• 802.11n
• 802.11ac

Older standards:

• b
• g

Newer standards:

• n
• ac

If all devices support a newer standard:

1. Access gateway Wi-Fi settings.
2. Change the Wi-Fi Radio mode to a single supported standard.
3. Save settings.
4. Test device connectivity.

Important

Changing to a single mode may prevent older devices from connecting.

If devices stop connecting:

1. Return the gateway to mixed mode.
2. Upgrade older devices if possible.

Upgrade Older Wi-Fi Devices

Older network adapters may limit network performance.

Consider upgrading:

• Internal Wi-Fi cards
• USB Wi-Fi adapters
• Legacy wireless devices

Preferred standards:

• 802.11ac
• Newer supported standards

Update Firmware and Drivers

Regular updates improve performance and stability.

Gateway Updates

1. Verify the gateway firmware is current.
2. Allow automatic updates when available.

Device Updates

1. Update operating systems.
2. Update wireless network drivers.
3. Install manufacturer firmware updates.
4. Restart devices after updates.

Troubleshooting Steps

Weak Signal in Certain Areas

1. Move the gateway to a central location.
2. Remove physical obstructions.
3. Install a Wi-Fi extender.
4. Test signal strength again.

Slow Speeds with Many Devices

1. Disconnect unused devices.
2. Move stationary devices to Ethernet.
3. Reduce background network activity.
4. Test performance again.

Devices Disconnect Frequently

1. Verify signal strength.
2. Update device drivers.
3. Restart the gateway.
4. Verify firmware is current.

Older Devices Running Slowly

1. Verify Wi-Fi adapter capabilities.
2. Upgrade outdated hardware if needed.
3. Update drivers and firmware.
4. Test performance again.

Expected Outcome

The customer's Wi-Fi network provides stronger coverage, improved internet speeds, reduced congestion, better device connectivity, and improved overall network performance.
