1. First, Understand Your Broadband

Broadband Speed Basics

Broadband Plan	Theoretical Download Speed	Real-World Experience
100M	12.5MB/s	Basic, sufficient
300M	37.5MB/s	Smooth experience
500M	62.5MB/s	Very good
1000M (Gigabit)	125MB/s	Blazing fast (requires full gigabit equipment support)

Note: Mbps (Megabits) ≠ MB/s (Megabytes), 1MB/s = 8Mbps. When an ISP says "1000M," they mean 1000Mbps, with a real-world maximum of about 125MB/s.

Key Factors Affecting Actual Speed

1. Whether the optical modem supports the corresponding speed (old modems may only support 100Mbps)
2. Whether the router supports the corresponding speed (100Mbps port vs. Gigabit port)
3. Whether the Ethernet cable is up to spec (Cat5e or higher supports Gigabit)
4. WiFi connection band and signal strength

2. Router Buying Essentials

WiFi Protocol Selection

Protocol	Max Speed	Bands	Recommended Now?
WiFi 5 (802.11ac)	1733Mbps	5GHz	Acceptable on a tight budget
WiFi 6 (802.11ax)	2402Mbps	2.4+5GHz	✅ Recommended
WiFi 6E	2402Mbps	2.4+5+6GHz	Only if your devices support it
WiFi 7	5764Mbps	2.4+5+6GHz	Flagship tier, high price

Current Sweet Spot: WiFi 6 router, best value for money, supported by the vast majority of devices.

Port Speeds

• 100Mbps Port: Cannot support broadband over 100Mbps, obsolete
• Gigabit Port (1Gbps): Current standard, supports broadband up to 1000Mbps
• 2.5G Port: Needed for broadband exceeding Gigabit

Pitfall to Avoid: Some budget routers have a Gigabit WAN port but 100Mbps LAN ports. Do not buy these.

Router Performance Metrics

• CPU: Dual-core or higher
• RAM: 128MB or more (256MB+ needed for many devices)
• Transmit Power: Domestic legal limits are 100mW (2.4GHz) and 200mW (5GHz). Check for external power amplifiers.

3. Mesh Networking Solutions

What is Mesh

Mesh is a seamless roaming network made up of multiple routers:

• Nodes (routers) connect to each other automatically
• Phones/computers switch between nodes without needing to reconnect manually
• All nodes use the same WiFi name and password

When Do You Need Mesh?

Floor Plan	Recommendation
Studio / 1-Bedroom	Single router is sufficient
2-Bedroom (60-80 sqm)	Single router placed centrally, or a 2-node Mesh
3-Bedroom (80-120 sqm)	2-node Mesh
Large / Duplex (120+ sqm)	3 or more Mesh nodes

Rule of Thumb: If signal drops significantly after 2 or more walls, you need Mesh.

Mesh Connection Methods

Connection Method	Speed	Stability	Best For
Wired Backhaul (nodes connected via Ethernet)	Fastest	Most Stable	Homes with pre-installed Ethernet cabling
Wireless Backhaul (nodes connected via WiFi)	Fast	Stable	Most renters
Hybrid Backhaul	Flexible	Good	Some nodes wired, some wireless

Recommended for Renters: Wireless backhaul Mesh. No cabling needed, just take it with you when you move.

Mesh Buying Considerations

Same Brand Compatibility:

• Mesh nodes must be from the same brand to form a network
• Routers from different brands cannot form a Mesh

Tri-Band vs. Dual-Band:

• Dual-band Mesh: Nodes and devices share the 5GHz band, competing for bandwidth
• Tri-band Mesh: Has a dedicated 5GHz backhaul band, doesn't affect device speeds
• Tri-band Mesh is recommended for large homes or homes with many devices

4. Practical Renter Network Setup

Option 1: Single Router (Small Apartment)

Recommended Setup:

• One WiFi 6 router
• Place it in the center of the home (not a corner)
• Place it as high as possible (on a bookshelf, top of a cabinet)
• Keep it away from interference sources like microwaves and metal cabinets

Option 2: Dual-Node Mesh (Medium Apartment)

Recommended Setup:

• Main node: Place it next to the optical modem (connect via Ethernet)
• Sub-node: Place it in the area with weak signal
• Distance between the two nodes should be about 5-10 meters (1-2 walls apart)

Placement Tips:

• Try to have a clear line of sight between nodes (minimize wall obstruction)
• Don't place the sub-node too far away (effectiveness drops if there are more than 3 walls between it and the main node)
• A "relay" position is more effective than an "endpoint" (place the sub-node between the main node and the signal dead zone)

Option 3: Powerline Adapter + Router (Special Scenarios)

Best For: Extreme cases where you can't run Ethernet and Mesh wireless signal is also insufficient.

How It Works: Transmits network signals through your home's electrical wiring.

• Pros: No Ethernet cable needed, any power outlet becomes a node.
• Cons: Speed is affected by the quality of your electrical circuit (may be poor in old buildings). Real-world speed is typically 50-200Mbps.

5. Optimization Tips

Band Selection

• 2.4GHz: Stronger penetration but slower speed and more interference (Bluetooth, microwaves, neighbor WiFi)
• 5GHz: Faster speed, less interference, but weaker penetration
• Use 5GHz for close range, 2.4GHz for long range

Channel Optimization

• Use a WiFi analyzer tool (e.g., WiFi Analyzer) to see channel congestion in your area
• Choose a less congested channel
• For 5GHz, choose channels 36/40/44/48 or 149/153/157/161

DNS Optimization

• Your ISP's default DNS can be slow
• You can switch to a public DNS:
  • 114.114.114.114 (Domestic)
  • 223.5.5.5 (Domestic public DNS)
  • 8.8.8.8 (International, may be slow to access domestically)

Security Settings

• Change the router's default admin password
• Choose WPA3 or WPA2/AES for WiFi encryption (do not choose WEP)
• Disable WPS (security vulnerability)
• Update router firmware regularly

6. Moving Migration Guide

Before Moving

• Record your router configuration (broadband account, WiFi name and password, port forwarding, etc.)
• Back up your router's configuration file (most routers support exporting the config)

After Moving

• First, confirm your broadband is installed at the new place
• Connect the optical modem to the main router
• Re-position the sub-nodes according to the new floor plan
• Test the speed in each area and adjust node placement as needed

📌 Core Advice: The priority order for setting up a rental network is: First, confirm your broadband speed → Choose the right router → Add Mesh nodes if needed. In most cases, one good WiFi 6 router placed in the right spot will perform better than multiple cheap routers.
