inSSIDer — Defeat Slow Wi-Fi

Most of us have a love-hate relationship with our Wi-Fi network. It is awesome when it works... and frustrating when it doesn't. inSSIDer helps to remove that frustration by showing you exactly how your network is configured, how neighboring Wi-Fi networks are impacting yours, and gives suggestions for fast, secure Wi-Fi.

Super convenient and just what we needed.

Very well constructed tool and accessory cables. This tool can help you find dead spots, overcrowded channels, and allows you to see everything in 2.4 and 5.8 GHZ ranges with on single antenna.

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.
