The Wi-Fi list shows two names that differ by one letter, a digit, or a 5G tail. The phone offers both, and the laptop is already on the wrong one. The password from your router does not fit the second name, or it does fit, and then those are your own two bands, not a neighbor.
You should connect to the name on the router sticker, matching every letter. Signal level does not prove the network is yours. A neighbor behind the wall can be louder than your 5 GHz.

What is happening
A router often shows two networks: 2.4 GHz and 5 GHz. 2.4 GHz reaches farther and is slower. 5 GHz is faster and weaker through walls. The names can look alike on purpose: one with a tail, one without. Both are yours if you set them that way in the router or if the sticker says so. The TV often sees only 2.4 GHz. The laptop sees both.
A stranger’s name copies yours almost word for word. The difference is a digit, a hyphen, an extra letter. Your network password does not have to fit a stranger’s network. If the password fitted both, check whether this is your router with two bands. Open the router page at the address from the sticker and see which names it broadcasts. The address is often 192.168.0.1 or 192.168.1.1, but not every box uses the same one.
A sign-in page that pops up right after you connect is another sign. Your home router usually lets you onto the internet without an extra form. A stranger asks for a phone, a code, or a mail password. Do not give that. Forget this name and go back to the sticker.
Your router’s guest network also looks like the main one if the name was chosen without looking. A guest network is a separate name and a separate password. You must not mix it up with a neighbor’s: you see the guest one in your own router settings, and the neighbor’s is not there. The router administrator password does not belong in this choice. It is not typed into the phone as Wi-Fi.
Auto-connect locks the mistake in. You tapped an almost-yours name once, and the phone sits on it by the door every day. Clear auto-connect or forget the twin. On Android that is more often a long press on the name. On iPhone it is the details button and Forget This Network. I do not promise one gesture for both phones.
How to choose between two of your own
In the same room as the router, take 5 GHz if the device sees it. Through walls, and for the TV, leave 2.4 GHz. Do not turn 2.4 GHz off only because the laptop is faster nearby on the five. The TV can lose the network.
If the names are yours and the speed is still poor on both, the issue is no longer the choice of letter. Move closer to the router. A wall cuts 5 GHz harder. Do not turn on a stranger network at full signal “to test the speed”: the test goes through a stranger’s router.
The laptop and the phone remember the choice separately. You fixed the phone, and in the morning the laptop sat on the twin again because the tick stayed in its list of known networks. Open Wi-Fi settings on the computer and clear auto-connect on the extra name. The line is like Manage known networks. On some builds it is named a little differently. Look for the meaning. Do not install a utility that promises to pick the network for you.
One shared name without a 5G tail can also cover both bands: the router spreads devices itself. Then there is no twin in the phone list, and an article about two lines does not apply to you. Two lines are there – read them to the last letter, including an underscore and an apartment digit if a neighbor named the network in a similar way.
What to check, in order
- Read the name on the router sticker. Compare it with the two lines in the phone list, letter by letter, including digits and a tail like 5G.
- If the sticker has two names, both can be treated as yours. For the TV, leave the one it sees. More often that is 2.4 GHz. For the laptop in the same room, 5 GHz.
- Type the Wi-Fi password from the sticker only into the name written on it. Do not try it on a neighbor’s twin.
- Open the router settings at the address from the sticker, with the administrator password, not the Wi-Fi password. See which names are on. No second name in the router means the second one in the phone list is not yours.
- Forget the stranger’s name. On Android hold the line. On iPhone open details. Do not delete your own name.
- Close a page that asks for mail or a code after you join a network. A home router usually does not do that.
- Do not go by the number of bars. A loud stranger network is weaker in meaning, even if it has more bars.
- Turn the guest name on for guests. Keep the main one for yourself. Those are different passwords. Both can be on one router.

Where people usually go wrong
- They pick the top line of the list without reading the tail of the name.
- They type their password into every similar network in a row.
- They kill 2.4 GHz and are surprised the TV is no longer on the network.
- They mix up the Wi-Fi password and the password for the router page.
- They treat 192.168.1.1 as the only address in the world and do not look at the sticker.
Two similar names are not always a neighbor. Match the sticker: your 2.4 and 5 GHz also sound almost the same. Forget a stranger name that is not in the router settings, and do not feed it a password.

What to do today
Put the sticker next to the network list and connect to the exact name. Leave the second of yours for the TV if it is 2.4 GHz. Forget everything that is not in the router, on the phone and on the laptop. Do not type a mail password on a page that popped up. Do not declare 5 GHz the only network in the house until you have checked whether the TV sees it.
