Why won’t my phone’s wifi hotspot stay connected?

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.

  1. 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.

  1. 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.

  2. 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.
  1. 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.

  1. 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.

  2. 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.
  1. 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.
  1. 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.

  1. 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.

Try rebuilding the hotspot connection from scratch.

Change your hotspot name and password. On your laptop, forget the old Wi-Fi network. Restart both devices, then connect using the new details. Keep only one device connected for 15 minutes.

This clears stale Wi-Fi profiles and corrupted saved settings, wich somtimes trigger repeated drops. If the conection stays stable, reconnect your other devices one at a time. Remove or update whichever device causes the hotspot to fail again.

Half the ‘random’ drops I’ve seen blamed on carriers are actually the 5 GHz band doing something people never think about. A lot of phones, when they run hotspot on 5 GHz, land on a DFS channel. Those channels are shared with radar, and if the phone thinks it detects anything it’s legally required to jump off that channel. To you that looks like a clean disconnect out of nowhere, every few minutes, with no pattern. So before you go down the carrier rabbit hole that @nachtschatten laid out, just force the hotspot to 2.4 GHz for a while and see if the drops stop. If they do, it was never your plan or your laptop.

The advice to flip between bands is fine, but flipping blind is a waste of time. That’s the one place the NetSpot suggestion earlier actually earns its spot, since seeing which channels are congested beats guessing. I’d treat it as a quick look, not a fix. It tells you where the noise is, it doesn’t stop your phone from parking on a bad channel on its own.

Where I’ll push back a bit: everyone’s stacking up VPN, DNS, IP conflict, battery optimization all at once. If you change five things and it stabilizes, you learned nothing. Change one, test long enough for it to normally drop, then move on. ‘A few minutes’ is a useful clue, so time it. Does it die at roughly the same interval every time, or only when traffic picks up? Same interval smells like a timeout or a channel event. Only under load smells like heat or carrier shaping.

One thing nobody mentioned that trips people up: cheap or older laptops sometimes can’t hold onto a phone’s 5 GHz hotspot cleanly at all, especially if the adapter is a basic single-band or a weak dual-band. If the phone stays connected to everything except the one laptop, stop blaming the phone. USB tethering that same laptop for an hour, like was suggested above, is honestly the fastest way to prove that in about two minutes of setup.
