Key takeaways
- Diagnosis comes before fixes: one device failing = TV, all devices failing = network, empty Wi-Fi list = LG says contact support.
- The hotspot test is decisive — if the TV joins a phone hotspot, your TV's radio is healthy and the fault is the router or ISP.
- Menu paths changed three times by webOS year: 2021+ uses General > Network > Internet Connection; 2020 uses Connection > Network Connection Settings; 2019 and earlier uses Connection.
- Wi-Fi passwords are case-sensitive (LG's own note) — retype it if the first attempt fails.
- LG's modem restart sequence: unplug modem ~10 seconds, replug, then router ~10 seconds, replug.
Step 1 — Diagnose: TV or network?
What it means: Other devices connect fine, or only the TV fails — the split decides everything.
- Check whether a phone, tablet, or laptop can use the same Wi-Fi network.
- If none can connect: the problem is the router or your ISP — restart the modem and router, or call your ISP.
- If only the TV fails: turn on the phone's mobile hotspot and connect the TV to it.
- If the TV connects to the hotspot, the TV hardware is fine; work on the router, the Wi-Fi name/password, or the position of the TV.
Step 2 — Set up the wireless connection (exact path by year)
What it means: the Wi-Fi menu moved across webOS versions; using the wrong path wastes time.
- On the remote, press the Settings (gear) button and choose All Settings in the top-left.
- TVs from 2021 and newer (webOS 6.0+): General, then Network, then Internet Connection, then Wi-Fi Connection.
- 2020 models (webOS 5.0): Connection, then Network Connection Settings, then Wi-Fi Connection.
- 2019 and earlier (webOS 4.5): Connection, then Wi-Fi Connection.
- Select your network, enter the password (case-sensitive), and confirm the TV reports connected.
- Wired option: plug an Ethernet cable into the TV — it detects the network automatically.
Step 3 — Check status and restart the chain
What it means: TV connects to router but router doesn't reach the internet.
- Open the TV's network status; if TV-to-router shows failed, recheck the Wi-Fi name and password.
- If TV-to-router is fine but the internet isn't there, restart the chain in this order: unplug the modem, wait about 10 seconds, plug it back in; then unplug the router, wait about 10 seconds, plug it back in.
- Reconnect the TV and recheck.
Step 4 — When to stop and call LG
What it means: these two symptoms are documented as service situations.
- If no networks appear at all — not even a phone hotspot — LG's guide says contact support; continuing to restart won't help.
- If the Wi-Fi Connection menu is greyed out or missing, LG lists that as a service case too.
