Here is an overview table showing the estimated Wi-Fi ranges from Wi-Fi 4 to Wi-Fi 7 depending on the type of obstacle (such as walls) and the presence of neighbors with their own Wi-Fi networks. This is based on typical estimates and may vary depending on equipment, interference and building materials.

📝 Explanation
Wi-Fi 4: Operates on 2.4 GHz, has the longest range but lower speed.
Wi-Fi 5: Operates on 5 GHz, offers higher speed but shorter range.
Wi-Fi 6: More efficient and better range than Wi-Fi 5, especially with many devices.
Wi-Fi 7: Latest standard, with higher speed, lower latency, and improved performance in busy environments.
🧠 Additional Notes
Steel walls reflect and absorb Wi-Fi signals, especially at higher frequencies like 5 GHz (Wi-Fi 5 & 6).
Wi-Fi 6 and 7 handle interference and obstacles better due to advanced techniques like beam forming and multi-band support.
Wi-Fi 7 can use multiple frequency bands simultaneously, improving range and stability in complex environments.
📡 Interference from Neighbors
The more neighbors with Wi-Fi, the more interference.
Wi-Fi 6 and 7 are better at handling congestion, thanks to technologies like OFDMA and Multi-Link Operation (Wi-Fi 7).
