Hi all..just 4 my general knowledge... can anyone give me a list of problems that may be caused by signal strength and range??? for example.. deadspot, congestion,....any other proposal?

Good question — and thanks for listing the common symptoms. Below are practical root causes, measurements, and fixes that go beyond what was already mentioned.

Common root causes include building materials that heavily attenuate RF (metal, concrete, foil-backed insulation), simple distance and free-space loss, destructive multipath from reflections, poor AP/antenna placement or orientation, mismatched client/AP radios or firmware, crowded 2.4 GHz spectrum and adjacent-channel overlap, and single-AP overload (too many clients). Also remember the 2.4 GHz vs 5 GHz tradeoff: 5 GHz gives capacity but shorter range.

Practical troubleshooting checklist:

  1. Measure actual RF: use a site-survey app (phone or laptop) or OS tools to read RSSI/SNR. Rule of thumb: RSSI around -67 dBm or better is good for typical data rates; SNR above ~20–25 dB helps sustain higher link rates.
  2. Run a continuous ping to the gateway to look for loss and jitter.
Windows:
netsh wlan show interfaces
ping -n 100 <gateway>

Linux/mac:
iwconfig
ping -c 100 <gateway>
  1. On 2.4 GHz, use non-overlapping channels (1, 6, 11) and reduce channel width to 20 MHz if congested. 4) Reposition APs (central, elevated, away from big metal objects) and align antennas. 5) Update AP/client firmware and drivers. 6) For larger coverage, add APs with wired backhaul and proper channel/power planning rather than relying on extenders or maxing transmit power. Caution: cranking power can create asymmetric links and more contention.

For complex or dense environments, a professional site survey with a spectrum analyzer will reveal hidden interferers and guide optimal AP placement.

Weak signal strength causes:
Deadspots
corrupt packets
vulnerability to interference
intermittent connectivity
lower throughput
and on some level added latency, since you are bound to have to resend packets
