Network marked “Public”? Common reasons + what to check first (Wi-Fi security, hotspot vs laptop label, sign-in pages, saved settings, updates)
Technician
Trust moment: Let’s start with the safest checks first. I don’t want you changing a bunch of settings or resetting anything just to make a label disappear.
Quick clarification so we don’t chase the wrong thing: where do you see “Public” — on the LG phone itself, or on a Windows computer that’s connected (for example to your phone’s hotspot)?
Technician
When Windows shows Public network, it’s usually a Windows safety profile. It doesn’t mean your phone is hacked. It simply means Windows is being cautious and may block things like discovery and printer sharing on that connection.
Before we change anything, what changed recently: a Windows update, a phone update, or is this a new hotspot name/password?
Technician
Small, safe check: does the laptop say “Public network” for every Wi-Fi, or only when you use the phone hotspot? For example, if you connect the laptop to your home router Wi-Fi, does it still call it public?
Technician
Another gentle check: on the LG phone, is the hotspot set with a password (WPA2/WPA3)? If a hotspot is open (no password), many devices treat it as untrusted and label it as public automatically.
Technician
Here’s the “misleading” part: Windows often defaults unknown networks to public, even if they’re safe enough for normal browsing. That can block printer discovery, file sharing, and “see other devices.”
Trust moment: I don’t want you to force the laptop into sharing mode on a connection you don’t fully trust. Let’s confirm the hotspot is truly yours and stable first.
When you connect, does internet work normally (websites load), and do you ever see a sign-in page message like “Sign in to network”?
Technician
One safe thing to check on the phone (no changes required): are you using any VPN, “private DNS,” or security app that recently updated? Sometimes these don’t cause danger, but they can change how networks behave and how devices re-identify a connection.
Technician
A practical point (and this is why people search for “network marked public”): if your goal is printing, a phone hotspot usually won’t behave like your home router. Many printers are on the home Wi-Fi, and your laptop on the hotspot is on a different “island,” so it can’t see the printer anyway — even if the label were private.
Do you mean a printer connected to your home Wi-Fi, or a printer that connects directly to the laptop by cable/USB?
Technician
If the laptop is on the phone hotspot, it’s not on your home Wi-Fi network, so it usually can’t discover the printer that lives on the home router. The public label adds extra blocking, but the bigger issue is that they’re on different networks.
Trust moment: I’d rather you understand the layout than flip sharing switches that might expose your laptop on a connection you don’t control.
If you reconnect the laptop to your home Wi-Fi (even briefly), does the printer appear again?
Technician
The safe takeaway: you can still browse and do normal things on the laptop, but sharing/discovery features may be limited — and your home printer won’t be reachable because it’s on a different network.
If you still want to change that label later, do it only for your own hotspot and only if you’re comfortable — but you don’t need to change anything just to stay safe.
Quick answer: the accepted fix
Accepted first approach when your LG phone network is marked as public (usually on a connected laptop): treat “Public” as a safety label, then confirm what device is showing it and what feature is actually blocked.
What usually helps most (safe checks):
• Confirm where the label appears (phone vs Windows) and what stopped working (printing, sharing, streaming, sign-in).
• Make sure the hotspot/Wi-Fi is password-protected and you recognize the network name (avoid open networks).
• If the goal is a home printer or file sharing, reconnect the laptop to the same home Wi-Fi as the printer/device (hotspot is a separate network).
• Look for “sign in to network” or captive portal prompts; these can make a connection feel “public/untrusted.”
• Change one thing at a time, and avoid major resets just to change a label.
Why it shows “Public” (and why it can start after an update)
On many systems, “Public” is a protective profile used for networks the device doesn’t fully trust yet. After an update, reconnect, or hotspot change, a computer may treat the connection as new and apply the cautious profile again. This can block network discovery, printer sharing, and “find devices on this network,” even if normal browsing works. It’s also common on hotspots because they behave differently than a home router. The important question is what feature is blocked — not the word itself.
What to check first: hotspot vs home Wi-Fi, passwords, sign-in pages, and saved network details
Start by separating where the label appears and what you’re trying to do. If Windows labels your phone hotspot as public, that mainly affects sharing and discovery — and it won’t usually allow access to devices (like printers) that live on your home router. If the message appears on the phone while joining Wi-Fi, check whether it’s an open network, whether there’s a sign-in page, and whether the phone is re-identifying the network due to saved settings (like randomized MAC behavior). Keep changes minimal and reversible, and test after each small adjustment.
“Public network” on an LG hotspot — gentle, senior-friendly quick help
Most of the time this is a Windows safety profile, not a sign that your phone is unsafe.
Try to identify what stopped working: browsing, printer discovery, file sharing, or a network sign-in page. If you’re trying to print to a home Wi-Fi printer, your laptop usually must be on the same home Wi-Fi as the printer — a phone hotspot is a separate network. Keep the hotspot password on, avoid open networks, and change one setting at a time. If you see a specific warning message, write it down; the wording matters.

FAQ
Why did my LG hotspot suddenly show up as “Public” on my laptop?
Windows often labels unfamiliar networks as public by default, especially hotspots. This can happen after phone or Windows updates or after a reconnect that makes it look like a new network. It mainly affects sharing and discovery, not basic internet browsing. The safest first step is confirming the hotspot is password-protected and recognized.
Did this happen after an update, and should I worry about security?
It’s common after updates because devices re-check network profiles. “Public” is usually a cautious setting, not proof of a hack. Still, avoid open hotspots and keep a strong password on your phone hotspot. If you see a sign-in page or unexpected network name, disconnect and re-check.
Is “public network” a phone setting, or is it coming from Windows?
Most of the time, it’s a Windows network profile label. Android phones don’t usually have the same public/private profile switch that Windows does. Your LG hotspot can be secure while Windows still chooses the public profile. What changes is whether Windows allows discovery and sharing on that connection.
Can I check this safely at home without resetting anything?
Yes. Confirm where the label appears, ensure your hotspot/Wi-Fi has a password, and test what works (browsing vs printing vs sharing). If you need a home printer, connect the laptop to the same home Wi-Fi as the printer. Avoid factory resets just to change a label.
