Quickly find access point details

The capabilities and configuration of your access points have a huge impact on whether your Wi-Fi is sloooow or fast. But this information is typically hidden for mesh systems or buried in a dozen configuration screens for standard Wi-Fi access points. With inSSIDer all of the important access point configuration details are shown in a single, easy-to-read list.

Discover which channels are busiest

Selecting a quiet channel for your Wi-Fi network will improve your Wi-Fi speed, and a channel with only a single Wi-Fi network can be much busier than a channel with multiple Wi-Fi networks. The Channels Table in inSSIDer shows you how busy each channel is, making it easy to find a channel that is relatively quiet compared to other channels.

See devices on your local network

inSSIDer not only shows your information about your Wi-Fi access points, it also scans your Local Area Network (LAN) to determine what devices are on your network. For some devices inSSIDer can even show you what type of device it is and automatically find the device name.

What professionals say

“inSSIDer...is like a Swiss Army Knife for WiFi troubleshooting.”

Pete Balkus, VP of IT at XOS Digital

“If you run a small office with a couple of wireless Access Points, you need this.”

Samuel C. CWNE

“I’ve fired up a copy of inSSIDer in several different home and SME environments… so all of them were competing for a time-slice of the same frequency. It’s so easy to spot these kinds of problems… and with a quick change of channel the wireless network suddenly starts working properly again.”
