My phone’s wifi hotspot keeps disconnecting my laptop and other devices after a few minutes of use. I’ve checked data limits, restarted everything, and even tried different locations, but the hotspot still drops randomly. I rely on this for work when I’m away from home, so I really need a stable connection. What settings or troubleshooting steps should I try to fix an unreliable mobile hotspot?
Phone hotspots drop for a few common reasons, and most are pretty boring stuff like power saving or radio conflicts. Here is what you should check, step by step.
- Turn off battery and hotspot power saving
- On Android, go to Settings > Battery and disable aggressive/battery saver modes.
- In Settings > Hotspot, look for options like “Turn off hotspot automatically” or “Timeout” and set to Never.
- On iPhone, keep the screen on while testing. Also disable Low Power Mode.

Disable Wi‑Fi on the phone while hotspot is on
If your phone connects to another Wi‑Fi while sharing data, it often freaks out and drops clients.
Use mobile data only when you run hotspot. No Wi‑Fi on the phone itself. -
Change hotspot band and name
- Change the SSID and password to something new. Short name, no special symbols.
- Switch between 2.4 GHz and 5 GHz in hotspot settings.
• 2.4 GHz works better through walls, slower but more stable.
• 5 GHz gives more speed but shorter range and more drops if signal is weak.
- Check laptop’s network settings
On Windows
- In Network & Internet > Wi‑Fi > Manage known networks, remove your hotspot, then reconnect.
- Run:
netsh winsock reset
netsh int ip reset
Then reboot. - In Device Manager, open your Wi‑Fi adapter, Power Management tab, uncheck “Allow the computer to turn off this device to save power”.
On macOS
- Delete the hotspot network from Wi‑Fi settings and reconnect.
- Turn off wireless power saving in any vendor tools if present.
-
Look for signal and channel issues
Crowded channels cause random drops, even if it looks like full bars.
Use a Wi‑Fi analyzer on your laptop or phone to see nearby networks and channels.
A good option for laptops is NetSpot Wi‑Fi analyzer and survey tool.
It helps you see interference, signal level in dBm, and which channel works best.
Pick a less crowded channel in your hotspot settings if your phone lets you. -
Carrier and data issues
- Some carriers throttle or drop hotspot traffic after a limit, even if regular data works.
- Try a different SIM or another phone on the same carrier if you have access.
- If it drops around the same usage amount every time, this screams carrier policy.
- Heat and hardware
Hotspot mode heats up phones. When they get hot, radios start failing or throttling.
- Take off the phone case, place it in open air.
- Avoid charging with a fast charger while hotspot runs.
If it keeps dropping only under heavy use or when hot, the phone’s radio or battery might be worn out.
- Test with a simple matrix
Do a quick test table to isolate the cause:
- Phone A hotspot to Laptop A
- Phone A hotspot to device B
- Phone B hotspot to Laptop A
If every combo drops, it points to interference or carrier.
If only “Phone A + any device” drops, it points to that phone.
If only “Laptop A + any hotspot” drops, it points to the laptop.
- Last resort resets
- Reset network settings on the phone. On Android and iOS there is a “Reset network settings” option.
- Update OS on phone and laptop.
- Try safe mode on the phone and test hotspot, in case some VPN or firewall app breaks it.
If you post your phone model, OS version, carrier, and whether it drops at a certain time or data amount, people can narrow it down more.

Had this exact circus with my hotspot for months, so here’s the stuff that usually gets missed on top of what @mikeappsreviewer already covered.
1. Check if your laptop is actually dropping, or just losing internet
First, figure out if:
- Devices are getting kicked off the hotspot Wi‑Fi itself
or - They stay “connected” but internet dies
If they still show “Connected” but nothing loads, it’s often:
- Carrier messing with tethering
- VPN / firewall / “security suite” on the phone or laptop breaking NAT
Try:
- Turning off any VPN, DNS app, “secure Wi‑Fi” or firewall app on the phone
- Temporarily disabling VPN / security suite on the laptop and see if it magically stays up
2. Watch for IP conflicts
Routers at home usually hand out addresses like 192.168.0.x or 192.168.1.x.
Some phones use the same range for hotspot, and if your laptop cached weird info from another network, things collide and you get random drops.
Stuff to try:
- On the phone hotspot settings, if possible, change the LAN range or at least toggle “AP isolation” / “Client isolation” if present
- On Windows, run in cmd (as admin):
ipconfig /release
ipconfig /renew
Yeah, @mikeappsreviewer mentioned some resets, but IP conflicts specifically can be super sneaky and feel like “random disconnects.”
3. Background junk on the phone killing the hotspot
A bit of disagreement here: just disabling battery saver is often not enough.
OEMs like Samsung, Xiaomi, etc. have extra “app sleeping” or “adaptive battery” nonsense that silently kills background services.
Check:
- Settings → Apps → Special access → Battery optimization
- Find “Tethering & Hotspot” or similar system app and exclude it
- Turn off vendor-specific stuff like “Ultra battery saver,” “Adaptive power saving,” “App hibernation,” etc.
I had a phone where hotspot only cut out once Instagram or TikTok was open long enough. Turned out the vendor optimization was throttling the radio when “screen on + heavy app” happened.
4. Check DNS specifically
Sometimes the Wi‑Fi connection stays live, but DNS dies, so everything looks like a disconnect.
On the laptop:
- Set DNS manually to 1.1.1.1 or 8.8.8.8 in Wi‑Fi adapter IPv4 settings
- Reconnect to hotspot and see if it stays stable longer
If that fixes it, the phone’s default DNS or carrier’s DNS over hotspot is just trash.
5. Interference & channel stuff, but actually check it, not guess
Since you already tried different locations, go one step more nerdy:
- Install NetSpot on your laptop
- Use it to scan around and check signal level in dBm, plus what channels are jammed
- If your hotspot settings allow, pick a cleaner channel and band based on that, instead of just flipping 2.4 / 5 randomly
NetSpot is honestly useful here because it shows if your signal is swinging wildly, which can look like the hotspot “dropping” when it’s really horrible RF conditions.
Example use:
“If I stand near the window, NetSpot shows my hotspot at like −45 dBm and stable, but when I sit on the couch it’s −80 dBm and spiking.”
That’s a pure signal issue, not software.
You can grab it here:
analyze & stabilize your Wi-Fi connection
6. Tethering type: try USB or Bluetooth
To narrow it down:
- Try USB tethering to the same laptop
- Try Bluetooth tethering
If:
- USB works fine for an hour
- Wi‑Fi hotspot drops after 5–10 minutes
Then the problem is almost certainly Wi‑Fi radio / interference / power management on the phone, not the carrier or the laptop.
7. Hidden carrier rules that look like “random” drops
Carriers sometimes treat hotspot traffic differently from normal phone traffic:
- They may cut off tethering after a short burst of high usage
- Some detect streaming / downloads and then reset the connection
Test:
- Use hotspot for light browsing only for 20–30 minutes
- Then do a speedtest or download something large and see if the drop happens soon after
Patterns like “fine until I stream or download, then instant drop” almost always point to carrier policies, even if your plan “allows” hotspot.
8. Quick, readable version for others landing here from Google
Why does my phone hotspot keep disconnecting my laptop and other devices?
- Check if your devices lose Wi‑Fi entirely or just lose internet
- Turn off VPNs, firewalls, and aggressive battery optimizations on both phone and laptop
- Fix possible IP conflicts and set a manual DNS like 1.1.1.1
- Use tools like NetSpot to check signal strength and Wi‑Fi channel congestion
- Try USB or Bluetooth tethering to see if the problem is Wi‑Fi only
- Watch for carrier limits that cut off hotspot when you hit certain data or speed usage
Once you know which of those buckets yours fits into, the “random” part usually stops being random and you can actually fix it instead of just rebooting stuff forever.
