Diagnosing Poor Wi-Fi Quality

For remote and home-office users, the Wi-Fi link is the most common blind spot. Tools that stop at the corporate edge never see it.

What to check

• Signal strength (RSSI): weak signal forces retransmissions and lower data rates.
• Channel congestion: neighbouring networks on the same channel cause contention.
• Roaming: devices that cling to a distant access point instead of switching to a closer one.

Quick wins

Move closer to the access point, switch to 5 GHz where available, and reduce competing devices on the same band during calls.
