FAQ

Is WiFi Explorer worth $20?

Depends on your needs.

Worth it if:

  • You have persistent WiFi problems (slow speeds, dropouts)
  • You need to optimize router channel (crowded neighborhood)
  • You’re managing WiFi for others (family, small office)
  • You’re an IT professional (tool pays for itself)

Not worth it if:

  • WiFi works fine (no problems to diagnose)
  • You just want to see signal strength (SignalPeek at $3 does this)
  • You’ll use it once and never again

Alternative: Try macOS WiFi Diagnostics (free) first. If you need more, buy WiFi Explorer.

Can these apps improve my WiFi speed?

They don’t directly improve speed. They help you diagnose problems.

How they help:

  1. Identify weak signal → Move closer to router or add extender
  2. Identify channel congestion → Switch router to less crowded channel
  3. Identify interference → Move router away from microwave, Bluetooth devices
  4. Identify bad connection → Reconnect to 5 GHz instead of 2.4 GHz

Example: WiFi Explorer shows 10 networks on channel 6. You switch router to channel 1 (empty). Speed improves 30%.

Do I need to buy WiFi Explorer Pro ($70)?

Probably not.

WiFi Explorer Pro adds:

  • Packet capture (for deep protocol analysis)
  • Signal mapping (walk around, see coverage map)
  • Multi-adapter support (scan with multiple WiFi dongles)

Most users need: WiFi Explorer Standard ($20). It has channel scanning and interference detection.

WiFi Explorer Pro is for:

  • Network engineers
  • Enterprise WiFi planning
  • Users who already know they need packet capture

Why is my WiFi signal weak even though I’m close to the router?

Possible causes (diagnose with these apps):

  1. High noise floor (interference from Bluetooth, microwaves, neighbors)

    • Check noise level in SignalPeek or WiFi Explorer
    • Move router away from interference sources

  2. Overcrowded channel (10+ networks on same channel)

    • Use WiFi Explorer to see channel occupancy
    • Switch router to less crowded channel

  3. Connecting to wrong band (2.4 GHz instead of 5 GHz)

    • 2.4 GHz has longer range but slower speeds
    • 5 GHz has shorter range but faster speeds
    • Use 5 GHz when close to router

  4. Router hardware issue (old router, faulty antenna)

    • Test with another device (does phone have same weak signal?)
    • If router is > 5 years old, consider upgrade

Can I use these apps to find my WiFi password?

No. These apps only show WiFi signal info, not passwords.

To find WiFi password:

  • macOS Keychain Access (search for network name)
  • Router admin panel (usually 192.168.1.1 or 192.168.0.1)

Do these apps work on iPhone/iPad?

No. Both are macOS-only.

iOS alternatives:

  • Airport Utility (free, basic WiFi scanner)
  • NetSpot (iOS version available, $9.99)
  • Fing (network scanner, free)
