The router ZTE F6640 moves away from the spider-like design of older routers with external antennas.

The lack of external antennas might initially suggest poor range, but the internal antenna array is tuned for 4x4 MIMO on the 5 GHz band, offering exceptional coverage for a 3-4 bedroom house. router zte f6640
Unlike Wi-Fi 5, which handles one device at a time per channel, the F6640 uses OFDMA (Orthogonal Frequency Division Multiple Access). This allows the router to communicate with multiple devices simultaneously. If your household has 20+ connected devices (smart TVs, phones, tablets, security cameras), you will notice significantly less lag and buffering.

Great hardware ruined by anti-consumer ISP lockdown.
The inclusion of a 10G Ethernet port is a game-changer. Most consumer routers still cap out at 1 Gbps. With the F6640, you can directly connect a high-end NAS (Network Attached Storage) or gaming PC to the 10G port for blistering internal transfer speeds. The lack of external antennas might initially suggest
Using a custom DNS (like Google or Cloudflare) can sometimes improve speed and security.
The headline feature of the ZTE F6640 is unquestionably its Wi-Fi 6 capability. If you are still using an 802.11ac (Wi-Fi 5) router, the F6640 represents a generational leap.
