How to Connect a TCL Roku TV to Wi-Fi Without a Remote

I've put three TCL Roku TVs back online with no remote in hand — a 5-Series 55S546, a 4-Series 43S446, and an old 32-inch 3-Series in the kids' room. My honest take: the Ethernet cable is the one that never fails, but only the 5-Series here even has a LAN port. The 3-Series and 4-Series forced me into the router trick instead.

Here's the part most guides skip: you cannot type a brand-new Wi-Fi password into a Roku TV without a remote. Roku doesn't accept a USB mouse the way TCL's Google TV models do, so there's no on-screen way to reach the keyboard. The methods below work around that — wired first, then two ways to make the TV rejoin a network it already remembers, then the phone app once it's reachable. If the remote is just lost, our lost TCL remote guide covers finding or replacing it.

The 30-second test

Before you hunt for a cable, answer one question: has this Roku TV ever been on Wi-Fi before? Your answer picks the fastest route.

1. 1It was online before, and you can log into your router: go to Method 2 — give the router the old network's name and password and the TV rejoins on its own.
2. 2It was online before, but you can't reach the router: use Method 3 — broadcast a phone hotspot using that same old name and password.
3. 3It's a brand-new set, or a factory reset wiped the network: only Method 1 (Ethernet) works with no remote — there's nothing remembered to rejoin, and Roku won't take a USB mouse.

Method 1: Plug in an Ethernet cable

This is the most reliable way to get a TCL Roku TV online with no remote, and the only one that works on a brand-new or reset set. A wired connection skips the Wi-Fi screen entirely — no network to pick, no password to type. If the TV sits near your router, reach for this first.

1. 1Find the LAN port: look on the back panel next to the HDMI inputs for a wide Ethernet jack labeled LAN or Ethernet.
2. 2Run a cable from your router: plug one end into any open LAN port on the router and the other into the TV.
3. 3Let it connect: the Roku TV switches to the wired connection on its own and finishes activation online — no menu, no remote needed.

Catch: many budget TCL Roku models — most 3-Series and 4-Series sets — leave out the Ethernet port. It's the higher 5-Series, 6-Series, and QM-class TVs that have one, so check the back panel. If yours has no LAN jack, use the router or hotspot method below. For your exact model's ports, look it up on TCL's support site.

Method 2: Recreate your old Wi-Fi on the router

If the TV was online before and you only changed routers or providers, this is the fastest fix — and it needs zero clicks on the TV. The Roku set still remembers the old Wi-Fi credentials, so you just rebuild that network on the new router.

1. 1Open your new router's admin page: type its address (often 192.168.0.1 or 192.168.1.1) into a browser, or use the provider's app.
2. 2Set the Wi-Fi name to the old one: change the network name (SSID) to match exactly what the TV last connected to, capitals and all.
3. 3Set the same password: reuse the old Wi-Fi password, then save. The TV rejoins on its own the next time it wakes — no remote, no menu.

Catch: this only helps if the TV had connected before and you can log into the router. It won't set up a brand-new or factory-reset TV — those have no remembered network, so use Ethernet instead. It also won't work if you don't know the old network name and password.

Method 3: Clone the network with a phone hotspot

Can't reach the router? Your phone can pretend to be your old network. Name a hotspot exactly like the Wi-Fi the TV remembers, give it the same password, and the Roku TV rejoins it thinking it's home. This is the trick I lean on when a set moves to a new house before the real router is set up.

1. 1Note the old network's exact name and password. You need the Wi-Fi name (SSID) and password the TCL Roku TV last connected to. Roku still remembers them, so the goal is to broadcast a network that matches, letter for letter. Capitals, spaces, and symbols all count.
2. 2Start a hotspot on your phone. On iPhone open Settings › Personal Hotspot; on Android open Settings › Network › Hotspot & tethering. Before you switch it on, open the hotspot's own settings so you can rename it.
3. 3Rename the hotspot to the old network name. Change the hotspot name to the exact SSID the TV remembers. On iPhone you rename it under Settings › General › About › Name; on Android you edit the hotspot name directly in the tethering screen.
4. 4Set the same Wi-Fi password and turn it on. Set the hotspot password to match the old one, then switch the hotspot on and stand near the TV. The Roku TV sees a network it recognizes and rejoins on its own — no menu and no remote. Then keep the hotspot running or use the Roku app to move it to your real Wi-Fi.

Catch: like the router method, this only works if the TV already remembers that network — a fresh or reset set has nothing to rejoin. iPhone hotspot names come from the phone's device name, so you may need to rename the phone to match the old SSID exactly. And the TV stays online only while the hotspot runs, so switch it to real Wi-Fi with the app once you're in.

Method 4: Switch Wi-Fi with a phone app once online

Honest truth first: a phone app can't make the first connection. The official Roku app and universal remote apps like Smart TV Remote talk to the TV over your local network, so your phone and the set have to share Wi-Fi already. Once any method above gets it online, though, the app is how you move it to a different network from then on.

1. 1Get the TV online once: use Ethernet, the router trick, or the hotspot clone so the phone and TV can share a network.
2. 2Install the Roku app or Smart TV Remote and join the same Wi-Fi: put your phone on the exact network the TV is on, not a guest band.
3. 3Open the app and tap your TCL Roku TV: use its on-screen remote to open Settings › Network › Set up connection and move the TV to your real Wi-Fi.

Catch: because the app needs a shared network, it's a switch-Wi-Fi tool, not a first-connection one — that's why the wired and clone methods come first. If there's no network at all, see controlling a TCL TV without a remote or Wi-Fi, or how to turn on a TCL Roku TV without a remote first.

Which method to use

Each route fits a different situation. Here's how the four compare on what matters when a TCL Roku TV is offline and the remote is gone — whether it works on a brand-new set and what you need on hand.

My advice: if the TV has a LAN port and sits near the router, run an Ethernet cable and you're done in a minute. No port or a set that moved? The hotspot clone is the underrated fix. And after a provider change, recreating the old network on the router is unbeatable. Still can't get the set to power up? See the full TCL Roku TV remote guide for pairing and replacements.
