Observations:

  • Ethernet Ports: The TL-WR844N, TL-WR841N V14, and TL-WR845N V4 offer more LAN ports (4) compared to the TL-WR820N V2 (2 LAN ports), making them more suitable for users requiring multiple wired connections.
  • Power Supply: The TL-WR841N V14 and TL-WR845N V4 models use a 9 V ⎓ 0.6 A power adapter, whereas the TL-WR820N V2 and TL-WR844N use a 5 V ⎓ 0.6 A adapter. This difference may impact energy consumption slightly but is not a major differentiator in terms of performance.
  • Physical Size: The TL-WR845N V4 is the largest, which may be due to its additional antenna and potentially more robust internal hardware to support that antenna array. This could offer slightly improved range or signal stability in multi-directions over the other models.
  • Antenna Configuration: The TL-WR845N V4’s third antenna may offer improved coverage and signal fidelity, particularly in environments where signal directionality and interference are issues.

Conclusion:

When choosing between these models, your decision may lean towards the TL-WR845N V4 if you require slightly better coverage and can accommodate its larger size. For most standard home applications, however, all models are fairly comparable, with the choice largely coming down to the number of required Ethernet ports and slight variations in physical dimensions and power requirements.
