Expanding home WiFi coverage often requires adding access points extending your network into dead zones. WiFi extenders and access points solve the frustrating problem of strong signals in some rooms while others get nothing. Setting these devices up correctly makes the difference between seamless coverage and constant connection drops.
Understanding how access points differ from routers and extenders helps you configure them properly. This guide walks through setting up home WiFi access points and troubleshooting common problems that prevent them working correctly.
Access Points vs Extenders vs Mesh Systems
Three main device types extend WiFi coverage with distinct approaches:
WiFi Access Points connect via ethernet cables to your main router creating new WiFi zones. They provide strongest performance since wired backhaul eliminates wireless relay delays.
WiFi Extenders connect wirelessly to your router rebroadcasting signals. Simpler setup but performance suffers as they use wireless bandwidth for both receiving and transmitting.
Mesh Systems use multiple units creating unified networks. Most expensive but easiest setup with automatic device hand-offs between nodes.
Access points deliver best performance for homes where running ethernet cables proves feasible. Extenders work when cabling isn’t possible. Mesh systems suit less technical users prioritizing simplicity.
Popular Home Access Point: TP-Link RE220
The TP-Link RE220 operates as both extender and access point depending on configuration mode. Many users struggle configuring it as an access point rather than extender.
Common RE220 Issues:
DHCP Conflicts: The RE220’s default DHCP server conflicts with your main router causing IP address problems and connection failures.
Network Loop Problems: Improper configuration creates network loops where signals route incorrectly causing instability and packet loss.
Firmware Bugs: Older firmware versions contain bugs affecting access point mode stability requiring updates.
Configuration Errors: Missing or incorrect settings prevent proper access point operation despite physical connections working.
Setting Up RE220 as Access Point
Proper configuration requires specific steps:
Connect RE220 to Router via Ethernet:
– Plug ethernet cable from main router into RE220’s LAN port (not WAN port)
– Power on the RE220 and wait for status lights stabilizing
Access RE220 Admin Interface:
– Connect computer to RE220 WiFi temporarily
– Open web browser and navigate to tplinkrepeater.net or 192.168.0.254
– Login with default credentials (admin/admin)
Switch to Access Point Mode:
– Navigate to Operation Mode or Settings menu
– Select Access Point mode (not Range Extender mode)
– Save settings and wait for device reboot
Disable DHCP Server:
– Go to Network Settings or LAN Settings
– Find DHCP Server option
– Disable or turn off DHCP server
– Your main router handles DHCP not the access point
– Save settings
Configure Static IP Address:
– Assign static IP within your router’s subnet but outside DHCP range
– Example: If router is 192.168.1.1 and DHCP range is .100-.200, use 192.168.1.50
– Set subnet mask matching your router (typically 255.255.255.0)
– Set gateway to your router’s IP address
– Save settings
Set WiFi Network Name and Password:
– Configure SSID (network name) – can match main network for seamless roaming or differ to identify access point
– Set strong password matching security standards
– Choose WPA2 or WPA3 encryption
– Save settings
Update Firmware:
– Check TP-Link website for latest RE220 firmware
– Download and install updates
– Firmware updates fix bugs affecting access point mode
Reboot and Test:
– Restart RE220 after configuration changes
– Connect devices to the new access point WiFi
– Test speeds and stability
Troubleshooting RE220 Access Point Problems
Several issues commonly affect RE220 operation:
Problem: Devices Connect But No Internet
Solution: DHCP conflict likely exists. Disable DHCP on RE220 ensuring only main router provides IP addresses. Check static IP settings matching your network subnet correctly.
Problem: Constant Disconnections and Packet Loss
Solution: Network loop probably exists. Verify ethernet cable connects to LAN port not WAN port. Check no other cables create loops between router and access point. Disable any bridging or DHCP relay features.
Problem: Slow Speeds Despite Good Signal
Solution: Wireless backhaul may be active despite ethernet connection. Confirm access point mode selected not extender mode. Check ethernet cable quality supporting gigabit speeds. Test wired connection speeds independently.
Problem: Can’t Access Configuration Interface
Solution: Static IP configuration may prevent access. Reset RE220 to factory defaults using reset button. Reconfigure carefully following steps above. Access via 192.168.0.254 immediately after reset before applying custom settings.
Problem: Devices Won’t Connect to Access Point
Solution: WiFi settings likely misconfigured. Check SSID broadcasting enabled. Verify password entered correctly. Confirm encryption type compatibility with your devices. Try temporarily disabling security to isolate issue.
Problem: Access Point Shows Offline or Unreachable
Solution: Network configuration errors exist. Verify static IP unique and within router’s subnet. Check ethernet cable securely connected and working. Ping the static IP address from another computer testing connectivity.
General Access Point Setup Best Practices
Several principles apply to any home access point:
Always disable DHCP on access points. Only your main router should provide IP addresses preventing conflicts.
Use static IP addresses for access points. Makes them reliably accessible for administration and troubleshooting.
Position access points centrally in coverage areas. Maximize signal reach minimizing dead zones.
Use quality ethernet cables rated Cat5e or better. Poor cabling limits speeds and reliability.
Keep firmware updated on all network equipment. Updates fix bugs and security vulnerabilities.
Match WiFi channels avoiding interference. Use WiFi analyzer apps identifying congested channels then select clearer alternatives.
Configure same SSIDs for seamless roaming or different SSIDs for manual network selection. Both approaches work depending on preferences.
Document your network configuration. Note IP addresses, passwords, and settings for future reference.
Comparing Access Point Brands
Several manufacturers produce reliable home access points:

Ubiquiti (UniFi): Professional-grade requiring controllers but exceptional performance and management. Popular with tech enthusiasts.
Netgear: Mid-range pricing with good reliability. Configuration generally straightforward.
ASUS: Gaming-focused with advanced features. Higher pricing but strong performance.
When Access Points Make Sense
Specific situations benefit from adding access points:
Large homes where single routers can’t cover all rooms adequately.
Multi-story buildings where signals struggle penetrating floors.
Homes with thick walls blocking WiFi signals in certain areas.
Properties with detached buildings requiring internet access.
Situations where ethernet cabling to remote locations proves feasible.
When to Choose Alternatives
Sometimes other solutions work better:
Mesh systems suit less technical users prioritizing plug-and-play simplicity.
WiFi extenders work when running ethernet cables proves impossible or impractical.
Upgrading main router delivers better coverage if current one uses outdated technology.
Powerline adapters with WiFi provide alternatives where electrical wiring supplements signals.
Security Considerations
Proper access point security prevents unauthorized access:
Use WPA2 or WPA3 encryption never WEP or open networks.

Change default admin passwords preventing easy unauthorized access.
Disable WPS if not actively using this feature reducing attack surface.
Update firmware regularly patching security vulnerabilities.
Monitor connected devices watching for unauthorized access attempts.
Maintenance and Monitoring
Regular maintenance keeps access points performing optimally:
Reboot access points monthly clearing temporary issues and memory leaks.
Check for firmware updates quarterly installing security patches and bug fixes.
Monitor performance using built-in tools or network monitoring software.
Review connected devices periodically removing unauthorized users.
Test speeds from different locations ensuring coverage remains adequate.
Adjust positioning if coverage patterns change or dead zones appear.
Common Configuration Mistakes
Several errors plague home access point setups:
Leaving DHCP enabled causes IP conflicts and connection failures.
Using overlapping WiFi channels creates interference and poor performance.
Incorrect subnet configuration prevents access point reaching internet.
Connecting to WAN ports instead of LAN ports confuses routing.
Outdated firmware contains bugs affecting stability and security.
Weak passwords allow unauthorized access compromising network security.
Poor placement in corners or behind obstacles limits effective coverage.
Testing Your Access Point Setup

Check IP address assignment ensuring devices get addresses from main router not access point.
Test internet connectivity from devices connected to access point WiFi.
Measure speeds comparing access point performance against main router speeds.
Verify roaming between access points and router working smoothly if using same SSID.
Check coverage in previously dead zones confirming signal strength improvements.
Monitor connection stability over hours watching for disconnections or packet loss.
WiFi access points significantly improve home network coverage when configured correctly. The key challenges involve disabling DHCP servers, assigning proper static IP addresses, and selecting access point mode rather than extender mode. TP-Link RE220 and similar devices work reliably once configured properly but confusing interfaces and poor documentation create setup difficulties. Following systematic configuration steps and troubleshooting methodically solves most common problems enabling seamless whole-home WiFi coverage.
