You connect to your hotspot or home WiFi… everything’s fine… then suddenly your phone switches to your neighbor’s open network.
No warning. No permission. Just slower internet and random disconnects.
Yeah—this is one of those annoying Android behaviors that feels broken.
Good news: you can stop it completely.
Quick Fix (Try This First)
- Turn OFF WiFi, wait 10 seconds, then turn it back ON
- Go to WiFi settings → tap the neighbor’s network → tap Forget
- Disable Auto-connect to open networks
- Turn OFF WiFi Assistant / Smart Network Switch
- Enable Metered network on your own WiFi or hotspot
This usually fixes it instantly.
Why This Happens
Android is designed to “help” you stay connected—but sometimes it overdoes it.
Here’s what’s really happening:
- Your phone detects a stronger open WiFi signal nearby
- It assumes open WiFi = better connection
- Features like WiFi Assistant automatically switch networks
- Saved networks + open networks compete in the background
This usually happens after updates, when settings get reset quietly.
Most people don’t notice this setting—even though it controls everything.
Step-by-Step Fixes
Turn Off Auto-Connect to Open Networks
This is the main cause.
- Go to Settings → Network & Internet → Internet
- Tap Network preferences
- Turn OFF Connect to open networks
On some phones, it may appear as “Auto-connect to public WiFi”.
Disable WiFi Assistant / Smart Switching
This is where things get tricky. Different brands name it differently.
- Look for options like:
- WiFi Assistant
- Smart Network Switch
- Adaptive Connectivity
Turn them OFF.
These features constantly scan and switch networks—even when you don’t want them to.
Forget the Neighbor’s Network
If your phone remembers it, it will reconnect.
- Go to WiFi settings
- Tap the neighbor’s open network
- Select Forget
Try this first if the issue keeps repeating.
Set Your Network as Metered
This tells Android: “this network matters—don’t switch away.”
- Tap your connected WiFi
- Find Metered or Treat as metered
- Turn it ON
It reduces aggressive switching.
Reset Network Settings (If Needed)
If nothing sticks, reset everything.
- Go to Settings → System → Reset Options
- Tap Reset WiFi, mobile & Bluetooth
This clears hidden bugs from system updates.
If It Still Doesn’t Work
Now we’re dealing with edge cases:
- Custom Android skins overriding settings (MIUI, ColorOS, etc.)
- Carrier apps forcing WiFi optimization
- Corrupted saved networks
In rare cases, your phone may reconnect because the open WiFi has no password—making it “priority” by default.
Extra Tips to Prevent This Issue
- Always forget unknown open networks immediately
- Keep WiFi off when using hotspot or mobile data
- Avoid connecting to public/open WiFi unless necessary
- Update your phone regularly (some bugs get fixed quietly)
Small habit. Big impact.
FAQ
Why does my Android keep connecting to random WiFi?
Because auto-connect and WiFi Assistant features are enabled by default.

Why does my phone ignore my hotspot?
It may detect a “stronger” open WiFi and switch automatically.
Does forgetting the network fix it permanently?
Usually, yes—unless auto-connect settings are still enabled.
Will turning off WiFi fix this?
Yes, but only temporarily. The real fix is disabling auto-switching.
