Fix TP-Link Archer 5GHz Wi-Fi Not Showing | Router 5GHz Missing | 5GHz Band Not Appearing- [Solved]

If yourTP-Link Archer C80 AC19600 Wireless Router ’s 5GHz Wi-Fi isn’t showing, here are some troubleshooting steps you can follow:

The 5GHz band on a router is part of dual-band wireless technology that operates on two frequency bands: 2.4GHz and 5GHz. Here are detailed insights into the 5GHz frequency:

1. Key Features of 5GHz Wi-Fi
Higher Speeds: Supports faster data transfer rates compared to 2.4GHz due to less interference and more bandwidth availability.
Shorter Range: Has a shorter effective range than 2.4GHz because higher frequencies don't penetrate walls and obstacles as effectively.
Less Congestion: Operates on less crowded frequencies, making it ideal for urban areas where 2.4GHz is oversaturated.
Ideal Use Cases: Best for tasks like HD streaming, online gaming, and file downloads, where speed is prioritized over range.
2. Channel Availability
Wide Range of Channels: 5GHz has 24 non-overlapping channels in many regions, reducing interference from other networks.
DFS Channels: Some routers support Dynamic Frequency Selection (DFS) channels, which provide additional bandwidth but may require devices to support them as well.
Regulatory Differences: Channel availability can vary based on country regulations.
3. Supported Wi-Fi Standards
5GHz is supported by the following Wi-Fi standards:

802.11n: Offers up to 600 Mbps with multiple-input, multiple-output (MIMO) technology.
802.11ac: Supports gigabit speeds (up to 3.5 Gbps) with wider channels and better efficiency.
802.11ax (Wi-Fi 6): Enhances speed, capacity, and power efficiency over 5GHz and introduces OFDMA for better device handling.
4. Typical Settings on Routers
Mode: Options like 802.11n, 802.11ac, or mixed mode for compatibility.
Channel Bandwidth: Common options are 20MHz, 40MHz, and 80MHz; 160MHz is available on high-end routers. Wider bandwidths offer higher speeds but may face more interference.
SSID: The 5GHz network typically has a separate SSID (e.g., "MyWiFi-5G") to differentiate it from 2.4GHz.
5. Device Compatibility
Hardware Support: Not all devices (especially older ones) support 5GHz Wi-Fi. Check for 802.11ac or newer support in your device specs.
Adapter Issues: Some network adapters need to be configured to detect 5GHz networks.
6. Advantages Over 2.4GHz
Better Performance in Crowded Environments: Ideal for apartments or cities where many devices compete for 2.4GHz bandwidth.
Less Interference: Avoids interference from devices like microwaves, Bluetooth, and cordless phones that often operate on 2.4GHz.
7. Challenges of 5GHz
Range Limitations: Effective mostly in the same room or open areas; performance drops significantly with walls or obstacles.
Setup Complexity: May require manual configuration for channels and compatibility settings.
8. Practical Tips for Optimizing 5GHz
Router Placement: Place the router in a central, open location for better signal distribution.
Choose the Right Channel: Use tools like Wi-Fi analyzers to find the least congested 5GHz channel.
