How to improve Wi-Fi signal?
•
Place the router in the center.
•
Raise it higher, without obstacles.
•
Change the channel if there is interference.
•
Update the firmware.
•
Use 5 GHz for speed, 2.4 GHz for range.
What is the difference between 2.4 GHz and 5 GHz?
•
2.4 GHz — farther, better through walls, slower.
•
5 GHz — faster, shorter radius, more channels.
•
Wi-Fi 6 works on both.
•
For video and gaming — 5 GHz.
•
For IoT devices — 2.4 GHz.
How to protect Wi-Fi?
•
WPA3 or WPA2 (not WEP/WPA).
•
Complex password.
•
Disable WPS.
•
Hide SSID (not very effective).
•
MAC filtering (bypassable).
•
Guest network for visitors.
What is Wi-Fi 6 (802.11ax)?
•
New Wi-Fi standard.
•
Higher speed, especially with many devices.
•
OFDMA — more efficient in crowded places.
•
Target Wake Time — battery saving.
•
Backward compatible with Wi-Fi 5.
What is Mesh Wi-Fi?
•
Multiple access points in a single network.
•
Seamless roaming between points.
•
Coverage of a large area.
•
Eero, Google Nest, TP-Link Deco.

Simpler than repeaters, more reliable.
Wi-Fi: how to choose a router and standards (Wi‑Fi 5/6/6E/7)?
Start with the requirements on the topic 'Wi-Fi': what should work, what are the limitations in terms of budget/performance/security. Then choose a solution.
Wi-Fi: how to select a channel and channel width for stability?
Practice for 'Wi-Fi': create a checklist (installation, setup, backup, updates) and go through it once — this reduces the number of 'mystical' problems.
Wi-Fi: how to set up a guest network and device isolation?
Answer on 'Wi-Fi': updates and backups are more important than fine-tuning. Automate backups and enable 2FA.
Wi-Fi: how to measure coverage and where to place mesh nodes/repeaters?
For 'Wi-Fi': it is useful to find the original source (documentation, release notes) and reproduce the problem with a minimal example.
Wi-Fi: question №10
If the question is about 'Wi-Fi', start with diagnostics: log, version, reproduction steps. This saves hours.
Wi-Fi: how to choose a router and standards (Wi‑Fi 5/6/6E/7)?
For 'Wi-Fi', it is better to use simple, supported solutions. Complexity should bring measurable benefits.
