Cookbook

Short recipes, a few taps each. Bottom bar names are in code style.

Find who is on my Wi-Fi

  1. Join the Wi-Fi.
  2. Open Network and tap Scan.
  3. Read Devices now and New today. Tap See all for the full list.

Missing one? Wake it and scan again, or tap Why a device may be missing.

Rename a device

  1. Open Network and tap the device.
  2. Tap Rename, type a name and tap Save.

Netglow knows it again by what it says about itself, even on a new address. Leave the name empty to give back its own name.

Keep my names safe with a names file

  1. Open Settings, then Device names file.
  2. Under Where it is saved tap Folder and pick a folder.

devices.json is saved there after every scan and rename, and stays when Netglow is removed.

Load my names on a new phone

  1. Install Netglow and copy devices.json to the new phone.
  2. Open Settings, Device names file, then Load a file.
  3. Pick devices.json. Netglow says how many devices it loaded.

If you picked a folder before, the file is already there. Pick the same folder again with Folder, then load it.

Check a rental for cameras

  1. Join the rental's Wi-Fi.
  2. Open Cameras and tap Check again.
  3. Tap Check nearby Wi-Fi too and allow location, to see camera hotspots nearby.
  4. Read each find. It says why it was flagged.

Netglow cannot see cameras that record to a card or use mobile data, or anything when the Wi-Fi keeps guests apart. A clean result is not a promise. Look around the room too.

Block an app with Firewall

  1. Install Firewall from Google Play and turn it on.
  2. Open Apps and tap the app.
  3. Tap Block in Firewall. Firewall asks you to confirm in its own dialog: tap Block.

The page then shows each connection, red when stopped and blue when it went out. If Apps says Another VPN may be on, see the runbook.

Block an app with Shizuku (Pro)

  1. Turn on Shizuku mode: Settings, Shizuku mode, then Get Shizuku, Open Shizuku and Allow Netglow.
  2. Open Apps and tap the app.
  3. Tap Block with Shizuku.
  4. To undo, tap Let it out again.

It needs Android 14 or newer. There is no VPN. After a reboot, start Shizuku again and Netglow sets the block again.

Turn on Background watch (Pro)

  1. Open Settings, then Background watch.
  2. Turn on Watch in the background.
  3. Tap How often to pick 15 minutes up to 6 hours, and keep Note for new devices on.

Netglow checks only while the phone is on Wi-Fi. Allow notifications when Android asks.

See who joined today

  1. Look at New today on Network.
  2. For more, tap Timeline in Everything Netglow does.
  3. Read Today, hour by hour and the joins and leaves below it.

If a device is yours, open it and tap It is mine so alerts skip it.

Ping a device

  1. Tap the device, then Ping.
  2. Tap Run. Netglow sends 10 pings and gives the average time.

Or open Tools, Ping, and type a name or address.

Check the ports of a device

  1. Tap the device, then Ports.
  2. Tap Run. You get the open ports, and what each is used for.

With Pro, type ports after the address, like 192.168.1.1 22, 8000-8100, up to 1000.

Wake a PC

  1. Turn on Wake on LAN in the computer's settings. Use a cable, or set it to wake by Wi-Fi.
  2. Tap the PC in Netglow, then Wake on LAN.
  3. Type its hardware address once, tap Save and Netglow sends the packet.

Nothing answers back. Give the PC a minute, then ping it.

Pick a clear Wi-Fi channel

  1. Open Tools, then Wi-Fi channels. Allow location when asked.
  2. Read how many networks sit on each channel, and the channel Netglow advises.

Netglow only shows it. Change the channel in the router's settings.

Check my network's security

  1. Run a scan on the Network screen.
  2. Tap the Security tile, then Security audit.
  3. Read the score, then open each risk for its fix. Run the other checks on the same page: Wi-Fi security, DNS check, Certificate check and Open to the internet.

With Pro, save it all with Audit report as a PDF or CSV.

Find where my Wi-Fi is weak

  1. Open Tools, then Signal meter.
  2. Walk slowly from room to room and watch the dial and the line of the last minute.

Where it turns amber or red, move the router or add a mesh point.

Look for trackers near me (Pro)

  1. Open Tools, then Bluetooth nearby. Allow Nearby devices when asked.
  2. Wait the 20 seconds of the scan.
  3. A tracker that seems to move with you pulses red on the radar.

Run it again after you have moved to a new place: a tracker that is still there is the one to look for.

Look at my router

  1. Open Tools, then Router check.
  2. Read each line. A line starting with "Look at this" needs attention.

Nothing is changed. To remove a device from your Wi-Fi, change the Wi-Fi password in the router.

Export my devices (Pro)

  1. Open Settings, then Watch and history.
  2. Tap Export devices and pick CSV or JSON.

No Pro? Share file on the names file page sends devices.json for free.

Switch to a dark theme

  1. Open Settings, then Look.
  2. Tap Dark or Black.
