The useful view of Wi-Fi

From a crowded spectrum to a decision you can act on.

WiFiBuddy turns CoreWLAN data into a channel map of signal overlap, channel pressure, and connection quality without sending your scan results anywhere.

01

Scan the room

Track nearby access points across 2.4, 5, and 6 GHz with RSSI, security, width, and PHY details.

02

See the overlap

Signal envelopes show which networks compete for airtime and where cleaner channels are available.

03

Respect the region

Channel guidance follows built-in regulatory policies for 18 regions, including DFS and 6 GHz availability.

04

Test stability

Measure latency, jitter, and packet loss against your router or DNS server without a cloud account.

Signal map

Networks become shapes, not rows.

Each curve shows the channel footprint and received signal strength of one access point. Hover to compare. Select to inspect. Filter by band when the room gets busy.
