Review: Android-based Wi-Fi stumblers

Four easy-to-use wireless management and security tools that cost under $2

Wi-Fi stumblers are handy when checking for channel usage, signal strength, security status, and detecting rogue access points, in situations where enterprise-level tools aren't necessary. We recently reviewed stumblers for your PC or laptop. Here's a look at a few Wi-Fi stumblers for your Android smartphone or tablet, which makes it even more convenient for quick and simple wireless checks.

This is one of the most basic Wi-Fi stumblers, but can still be useful for simple channel and signal checks for access points in the 2.4GHz band.

Once you open it, you'll find a small bar graph showing how many access points are detected per channel (1 - 11 only), which can quickly help you identify possible channel overlapping. It also displays in numerical values how many SSIDs and access points are detected. You'll also find a SSID list, displaying the channel(s), signal (RSSI in dB), security type, and any detected access point vendor. Though it displays the security type, it doesn't distinguish between the personal (PSK) and enterprise (EAP) modes of WPA or WPA2.

It automatically sorts the SSID list alphabetically and doesn't let you sort by any other means, which could be an issue when browsing through a dozen or more SSIDs. It does however group access points with the same SSID and represents them as one entry on the main list. But the signal shown will only represent the access point with the highest signal.
