8. Advanced (optional)

• Port forwarding: configure under NAT > Virtual Server for gaming/servers.
• DMZ: use only for troubleshooting or trusted device.
• VPN passthrough: enable for remote access clients.

• No 6 GHz Band (Wi-Fi 6E): This is a purely Wi-Fi 6 router. It does not support the new 6 GHz spectrum, which means more interference in apartment blocks.
• No 2.5G Ethernet Port: In 2024/2025, high-end routers often include a 2.5Gbps WAN port. The F6640 sticks to Gigabit, meaning you cannot fully utilize fiber plans above 1Gbps (if your ISP offers 1.5Gbps or 2Gbps).
• ISP Locking: Depending on your provider, the F6640 might be locked down. Some features (like bridge mode or DNS changes) may require a call to technical support for a "super password."

• Default is often admin / admin or user / user.
• ISP Lock Warning: Many providers lock the admin account. If admin doesn't work, check the sticker for a specific "User" login (often user / user), which has limited privileges.

LAN: Four Gigabit Ethernet (GE) ports for high-speed wired connections. router zte f6640
