Quick Answer
You can connect a smart TV to Wi‑Fi without its remote by plugging in a USB keyboard or mouse to navigate settings, using the TV maker’s mobile app if it supports Bluetooth onboarding, temporarily connecting an Ethernet cable, or cloning your home Wi‑Fi name and password on a phone hotspot so the TV auto‑rejoins. Other options include using the TV’s physical buttons, a universal IR remote or IR‑blaster phone, and WPS if you can open the option on the TV with on‑device controls or a USB mouse.
What You’ll Need (Pick One or Two)
You don’t need everything here—choose what matches your TV and what you have available.
- A wired USB keyboard or mouse (or a 2.4 GHz wireless set with a USB dongle)
- Your smartphone with the correct brand app (SmartThings, LG ThinQ, Google TV, Roku, Vizio SmartCast, Hisense RemoteNOW, etc.)
- An Ethernet cable and access to your router or a nearby Ethernet jack
- A smartphone hotspot you can rename to match your home Wi‑Fi SSID and password
- A phone with an IR blaster or a low‑cost universal IR remote
- Access to the TV’s physical buttons or joystick control (often under the bezel)
Best Methods That Work On Most TVs
1) Plug in a USB keyboard or mouse
This is the most universal method because most smart TVs support USB‑HID input. A simple wired USB keyboard or mouse usually works immediately; 2.4 GHz wireless models with a USB receiver also work on many sets.
- Power on the TV and plug the keyboard or mouse into a USB port on the TV.
- Use the keyboard’s arrow keys and Enter, or move the mouse to bring up a cursor.
- Open Settings or Menu, then Network or Wi‑Fi.
- Select your Wi‑Fi network and enter the password using the keyboard, or click with the mouse.
If one USB port doesn’t detect input, try another. When an on‑screen keyboard appears, type directly on your physical keyboard to fill fields faster.
2) Use the TV maker’s mobile app (Bluetooth onboarding where supported)
Many brands let you discover and set up a TV over Bluetooth, then pass Wi‑Fi credentials from your phone—even if the TV isn’t on Wi‑Fi yet. Support varies by model and year; check your TV’s compatibility in the app store listing.
- Samsung: SmartThings can discover many 2016+ models via Bluetooth and guide Wi‑Fi setup.
- LG: LG ThinQ supports onboarding many webOS models using Bluetooth proximity, then Wi‑Fi configuration.
- Sony/Google TV and other Android TV sets: The Google TV app and “Set up a device” flow help during initial setup on supported models. For already‑configured sets that are offline, a USB keyboard is often faster.
- Vizio: SmartCast Mobile can pair to many SmartCast displays via Bluetooth LE and help complete Wi‑Fi configuration.
- Install the brand app and enable Bluetooth and Location services on your phone.
- Open the app, choose Add Device or TV Remote, and stand near the TV.
- Follow the prompts to pair and send Wi‑Fi credentials, or to control the TV long enough to open Network settings.
Note: Some brand apps only work once the TV is on the same Wi‑Fi. If your app never finds the TV, use a USB keyboard/mouse or temporarily connect Ethernet, then return to the app.
3) Temporary Ethernet, then switch to Wi‑Fi
If your TV has a LAN port, a short cable run to your router gets you online immediately. Once the TV is on the internet via Ethernet, most mobile remote apps will work because they’re on the same network. You can then switch the TV to Wi‑Fi in settings and unplug Ethernet afterward.
- Connect an Ethernet cable from the TV to a LAN port on your router.
- Wait 30–60 seconds for the TV to obtain an IP address.
- Use the brand app on your phone to control the TV, or use a USB keyboard/mouse to open Wi‑Fi settings.
- Connect to your wireless network, confirm “Connected,” then remove the Ethernet cable if you prefer Wi‑Fi.
4) Rename your phone’s hotspot to match your old Wi‑Fi
If the TV previously connected to your home Wi‑Fi and still has those credentials saved, you can “trick” it into reconnecting by cloning the same SSID and password on your phone’s hotspot. The TV will usually auto‑join if it sees an exact match.
- On your phone, create a hotspot named exactly the same as your regular Wi‑Fi SSID, with the identical password and security type (WPA2/WPA3).
- Turn on the hotspot and wait up to a minute for the TV to auto‑reconnect.
- With both devices on the hotspot, use the brand app or a USB keyboard/mouse to open Wi‑Fi settings and switch the TV back to your home network.
Mind mobile data limits. Streaming while connected to your hotspot will consume mobile data.
5) Use the TV’s physical buttons or joystick
Most TVs have a small joystick or a few buttons along the bottom edge, side panel, or behind the logo. You can usually open inputs and a basic settings menu from there.
- Feel under the bezel for a five‑way joystick or a cluster of buttons (Power, Volume, Input/Menu).
- Press or hold the Menu/Input button to open on‑screen options.
- Use short presses to move and long presses to select. Navigate to Network or Wi‑Fi and connect.
Controls are limited, so a USB keyboard or mouse can speed things up if the TV supports it.
Other Methods That Can Help
Try an IR‑blaster phone or a budget universal remote
Some phones (for example, select Xiaomi, Huawei, older Samsung, and a few mid‑range Android models) include IR hardware. With an IR remote app—or with a $10 universal IR remote—you can send arrow/OK commands to open the TV’s Wi‑Fi menu.
- Install a reputable IR remote app and select your TV brand, or program a universal remote with the brand code.
- Point at the TV’s IR receiver (usually bottom center) and use arrows/OK to reach Network/Wi‑Fi.
WPS push‑button (only if you can trigger it on the TV)
Some TVs support WPS. You must start WPS on the TV’s Wi‑Fi menu and press the WPS button on your router within two minutes. Without a remote, use a USB mouse or on‑TV buttons if they allow full menu access.
- Open Wi‑Fi settings on the TV and choose WPS (Push Button) or WPS (PBC).
- Press your router’s WPS button and wait for the TV to report “Connected.”
WPS may be disabled on some routers and isn’t available on every TV model.
HDMI‑CEC control from another device (limited)
Game consoles and streaming sticks can send basic Consumer Electronics Control (CEC) commands over HDMI. On some TVs, this lets you navigate limited on‑screen menus, but many sets restrict CEC to power/volume/input. If you already have a console or stick connected, try its remote. If navigation doesn’t work, switch to a USB keyboard or IR remote.

| WPS push‑button | No | Router with WPS and TV menu access | Medium | When you can open WPS on the TV without a remote |
Brand‑Specific Tips
Samsung Smart TV
Best bets: USB keyboard/mouse, the SmartThings app (Bluetooth onboarding on many 2016+ models), or Ethernet. Many Samsung sets have a tiny joystick under the logo—long‑press to open a simple menu, then step into Network. SmartThings typically discovers nearby TVs when Bluetooth and Location are enabled on your phone. If the app won’t pair, connect Wi‑Fi with a USB keyboard, then return to SmartThings for full control.
LG webOS TV
Best bets: USB keyboard/mouse, LG ThinQ with Bluetooth proximity onboarding, or Ethernet. Many LG sets have a bottom‑center joystick; long‑press to open settings. If the ThinQ app sees your TV but can’t control it yet, complete the Add TV flow with your phone near the set—or connect via USB keyboard first and then pair the app over your home network.
Sony Google TV / Android TV (and other Google TV brands)
Best bets: USB keyboard/mouse or Ethernet. The Google TV app remote works over the local network; some models support phone‑assisted setup via Bluetooth during the initial out‑of‑box flow. If the TV is already past initial setup and offline, a USB keyboard/mouse is the quickest path to Wi‑Fi. Once online, the Google TV app remote works smoothly.
Roku TV (TCL, Hisense, Sharp, Onn, etc.)
Best bets: Ethernet if your model includes a LAN port, the hotspot SSID/password trick, or an IR remote. Roku’s mobile app requires the TV and phone on the same network, and many Roku TVs do not support USB keyboards or mice. If there’s no Ethernet port, use the hotspot trick or a universal IR remote to reach Wi‑Fi settings.
Vizio SmartCast
Best bets: SmartCast Mobile with Bluetooth LE onboarding on supported models, USB keyboard/mouse, or Ethernet. Place your phone close to the TV and follow the SmartCast pairing flow. If pairing fails, connect a USB keyboard and finish Wi‑Fi from the TV’s network menu.
Hisense and TCL (non‑Roku variants)
These lines ship with different platforms (Google TV/Android TV, VIDAA, etc.). USB keyboard/mouse and Ethernet are the most consistent options. Some Hisense models support the RemoteNOW app over Wi‑Fi only; get the TV online with Ethernet or the hotspot trick, then use the app.
Step‑By‑Step: Keyboard/Mouse Method (Universal)
- Plug a wired USB keyboard or mouse into the TV. If the TV has multiple USB ports, try the one labeled USB 2.0 or USB‑HID if available.
- Press any key or move the mouse. If a cursor appears, continue with the mouse; otherwise, navigate with arrow keys and Enter.
- Open Settings > Network (or Connections) > Wi‑Fi.
- Select your SSID, type the password, and confirm. If the TV sees both 2.4 GHz and 5 GHz, choose the band with stronger signal in that room.
- After connecting, test with a built‑in app (for example, YouTube) or use your brand’s mobile app for remote control over Wi‑Fi.
Troubleshooting Tips
- Keyboard or mouse not detected: Try another USB port. Prefer a simple wired model. Avoid USB hubs; connect directly.
- No Wi‑Fi networks found: Move the router closer. Some older TVs only support 2.4 GHz; others cannot see DFS channels on 5 GHz. If possible, set your router to a non‑DFS 5 GHz channel or use 2.4 GHz.
- Connection fails on WPA3: Older TVs may not support WPA3. Enable WPA2/WPA3 mixed mode on your router or create a WPA2‑only guest network to connect the TV.
- Hotspot trick not working: Ensure the SSID, password, and security type exactly match the TV’s remembered network. If your TV is 2.4 GHz‑only, disable 5 GHz on the hotspot.
- Brand app cannot find TV: Enable Bluetooth and Location on your phone, turn off VPNs, and connect the phone to the same network. Disable “AP/client isolation” or “guest isolation” on the router, which can block device discovery.
- Ethernet link down: Confirm the router LAN port is active and the cable clicks in at both ends. Try a different cable or port.
- WPS fails: Verify WPS is enabled in your router’s admin panel. Start WPS on the TV first, then press the router’s WPS button within the time window. Consider turning WPS off again afterward for security.
- CEC control limited: If a console or streaming stick doesn’t navigate the TV menu, that’s expected—most TVs restrict CEC to power/volume/input. Use a USB keyboard or an IR remote instead.
- Still stuck offline: Power‑cycle the TV and router, then retry your chosen method. As a last resort, a cheap universal IR remote almost always enables basic navigation.

Safety, Privacy, and Practical Notes
If you use a phone hotspot, streaming can quickly consume mobile data. Turn the hotspot off once initial setup is complete and reconnect the TV to your regular Wi‑Fi. If you run a temporary Ethernet cable across a floor, tape it down to prevent trips. If you plan to rely on a phone app as your long‑term remote, set a TV PIN or account protection so only your household can control it.
Frequently Asked Questions
Can I use any USB keyboard with my TV?
Most wired USB keyboards work, and many 2.4 GHz wireless keyboards with a USB dongle do as well. Bluetooth keyboards usually require pairing in the TV’s settings, which is hard without a remote, so stick with USB when possible.
My phone’s remote app can’t find the TV. What should I try next?
Enable Bluetooth and Location on your phone and turn off any VPN. Connect the phone to the same network as the TV (or to the temporary Ethernet network if you used a cable). If discovery still fails, bring the TV online with a USB keyboard/mouse or the hotspot SSID match, then retry the app.
Will the hotspot SSID trick work if the TV never connected to my Wi‑Fi before?
No. The trick relies on the TV automatically joining a remembered network. If the TV has never seen your Wi‑Fi, use a USB keyboard/mouse, Ethernet, or a brand app that supports Bluetooth onboarding.
Is WPS safe and should I use it?
WPS is convenient but has known security weaknesses. If you use it, turn WPS off afterward in your router settings. When possible, connect by selecting your SSID and entering the password in the TV’s network menu.
Can I control the TV with a game console or streaming stick remote?
Sometimes. HDMI‑CEC may let another device send basic commands to the TV, but many sets limit this to power, volume, and input. It’s not a reliable way to complete Wi‑Fi setup—use a USB keyboard/mouse or an IR remote instead.
What if my TV doesn’t have an Ethernet port?
Many slim or budget models—especially some Roku TVs—omit Ethernet. In that case, your best options are a USB keyboard/mouse, the brand app if it supports Bluetooth onboarding, an IR remote, or the hotspot SSID trick if the TV remembers your network.
