Why is my LG TV not connecting to WiFi after a factory reset?

After a factory reset, the TV's saved network profile (SSID, password, security certificates) is completely erased. You must re-enter your WiFi password manually. Common post-reset failures occur when: (1) the password is entered incorrectly — use the 'show password' option to verify, (2) the router uses WPA3 which some webOS versions reject silently, or (3) the router has MAC filtering enabled and the TV's MAC address was removed from the whitelist during the reset. Navigate to Settings → Network → Wi-Fi Connection, select your SSID, and re-enter credentials. If that fails, try the WPA2-only router fix described above.

Why won't my 2022 LG TV connect to WiFi automatically?

LG TVs with webOS 22 (shipped with 2022 models) have a known bug where auto-reconnect fails after the TV enters deep standby mode. The workaround is: (1) Go to Settings → All Settings → General → Quickstart+ and disable it, which keeps the network stack active during standby. (2) Alternatively, enable Settings → All Settings → Network → Keep Network Connection Active During Power Off if available on your model. Also ensure your router's DHCP lease time is set to at least 24 hours so the TV's IP reservation does not expire overnight.

My LG TV connects to WiFi but shows 'No Internet' — what do I do?

This means the WiFi handshake succeeded (Layer 2 is fine) but the TV cannot route traffic to the internet (Layer 3 failure). Most common causes: (1) ISP outage — test with another device. (2) DNS failure — change TV DNS to 8.8.8.8 manually as described in Fix 4. (3) Router firewall blocking LG's servers — temporarily disable any content filtering or parental controls and retest. (4) Captive portal — if you're on a hotel or enterprise network, the TV's browser may need to authenticate. Open the LG browser app and navigate to any HTTP site to trigger the portal.

My LG TV is not finding my WiFi network in the list at all — what's wrong?

If the SSID doesn't appear in the scan list: (1) The TV may only support 2.4 GHz — check your model spec and ensure 2.4 GHz is enabled on the router. (2) Your router may be broadcasting on channels 12, 13, or 14 which are blocked in the US — switch to channels 1, 6, or 11. (3) The SSID may be hidden — use 'Other Network' to manually enter the network name. (4) There may be RF interference — temporarily move the router closer to the TV. (5) The TV's WiFi hardware may have failed — try an Ethernet connection to confirm.

Does LG TV WiFi not connecting after a firmware update have a fix?

Yes. Firmware updates occasionally overwrite network driver configurations. After an update that breaks WiFi: (1) Do a network-only reset: Settings → All Settings → General → Reset to Initial Settings → Network. (2) If the update introduced a WPA3 incompatibility, switch your router to WPA2. (3) Check LG's support site for a subsequent patch — LG often releases a hotfix within 4-6 weeks of a problematic OTA. You can download and apply the hotfix via USB as described in Fix 6. (4) As a last resort, if the update itself was corrupt, LG support can provide a recovery firmware image.

Key Takeaways

Root cause 1: Corrupted network cache or stale DHCP lease — the TV holds an old IP assignment that conflicts with the router, preventing a new handshake.
Root cause 2: Firmware bugs in 2022-era webOS builds (webOS 6.x/7.x) introduced a regression where WPA3-only networks and certain 5 GHz channels are silently rejected without an on-screen error.
Root cause 3: After a factory reset the TV loses all saved SSIDs and stored certificates, so it must re-authenticate from scratch — any mismatch in security protocol or hidden-SSID settings causes a silent fail.
Quick fix summary: (1) Power-cycle the TV and router, (2) forget and re-add the WiFi network, (3) change the router security mode to WPA2, (4) manually set DNS to 8.8.8.8, and (5) update LG firmware via USB if OTA fails.

Fix Approaches Compared
Method	When to Use	Time	Risk
Power-cycle TV + Router	First attempt for any WiFi failure	2 min	None
Forget & Reconnect WiFi	TV sees the network but fails to authenticate	3 min	None
Change Router to WPA2-AES	WPA3 or mixed-mode causing silent rejection	5 min	Low — may affect other devices briefly
Manual DNS (8.8.8.8 / 8.8.4.4)	TV connects but shows 'No Internet' or drops after seconds	2 min	None
Firmware Update via USB	Known webOS 6/7 bug; OTA update fails due to no connection	20 min	Low — do not power off during flash
Network Settings Reset (Menu)	After factory reset or persistent DHCP conflict	5 min	Clears all saved networks
Factory Reset (Full)	All else fails; TV won't retain any network config	15 min	Erases all user data and apps
Static IP Assignment	DHCP server not responding or assigning duplicate IPs	5 min	Low — must keep IP outside DHCP pool

Understanding Why LG TVs Fail to Connect to WiFi

LG smart TVs run webOS, a Linux-based operating system with a proprietary network stack. Unlike a laptop or phone, the TV's WiFi subsystem is tightly coupled to the webOS firmware version, meaning a bug in one release can silently break WiFi for an entire product line. The most common on-screen errors you'll see include:

"Cannot connect to the network" — generic DHCP or authentication failure
"Check your internet connection" — DNS resolution or gateway routing failure
"Unable to connect to the LG server" — network is up but LG's cloud endpoint is unreachable
"Password incorrect" — can appear even with the correct password when WPA3 is the culprit
"IP address conflict" — duplicate IP on the local network

Understanding which error you see narrows the fix dramatically.

Step 1: Diagnose — Identify the Exact Failure Point

1.1 Check what the TV can see

Go to Settings → All Settings → Network → Wi-Fi Connection. If your SSID appears in the list, the 2.4/5 GHz radio is functional and the router is broadcasting. If it does not appear:

Move the TV closer to the router to rule out signal strength.
Ensure the router is broadcasting (not in stealth/hidden mode) or manually enter the SSID.
Check that the router's 2.4 GHz band is enabled — some LG models (especially 2019 and older) do not support 5 GHz.

1.2 Note the exact error message

Write down the exact text shown on screen. The error code (e.g., Error 106, Error 137) maps to specific failure modes:

Error 106 — Cannot reach LG content server (DNS or firewall issue)
Error 137 — Session timeout; re-authentication required

1.3 Test with a mobile hotspot

Create a personal hotspot on your phone using the exact same SSID and password as your home network (or a different one to isolate variables). If the TV connects to the hotspot but not your router, the problem is router-side (security mode, channel, band steering, or MAC filtering). If it fails on the hotspot too, the problem is TV-side.

1.4 Check router logs

On your router's admin panel (typically at 192.168.1.1 or 192.168.0.1), look at DHCP leases and the wireless association log. A failed WPA handshake will appear as a deauth or 4-way handshake timeout. A successful association followed by no traffic indicates a DNS or routing issue.

Step 2: Fix — Apply Solutions in Order

Fix 1: Power-Cycle Everything

This resolves roughly 30% of cases by clearing the DHCP lease cache and reinitializing the WiFi radio.

Turn off the LG TV and unplug it from the wall (not just standby — physically unplug).
Turn off your router and modem. Unplug both.
Wait 60 seconds.
Plug in the modem first, wait 30 seconds. Plug in the router, wait 30 seconds.
Plug the TV back in and attempt to connect.

Fix 2: Forget the Network and Reconnect

A corrupted stored network profile is a frequent culprit, especially after a firmware update.

Go to Settings → All Settings → Network → Wi-Fi Connection.
Select your network name.
Press the red button (or select "Forget") to remove the saved profile.
Re-select the network, re-enter the password carefully (passwords are case-sensitive).

Fix 3: Change Router Security Mode to WPA2-AES

webOS 6.x (shipped on 2021-2022 LG TVs) has a documented incompatibility with WPA3 and WPA2/WPA3 mixed mode. In your router admin panel:

Navigate to Wireless Security settings.
Change the authentication mode from WPA3 or WPA2/WPA3 Mixed to WPA2-Personal (AES/CCMP only).
Save and reboot the router.
Retry the connection on the TV.

If you cannot change your router settings (e.g., ISP-locked), try enabling a separate 2.4 GHz guest network with WPA2-only security and connect the TV to that.

Fix 4: Set Manual DNS Addresses

Some ISP-provided DNS servers block LG's CDN endpoints. Overriding with public DNS fixes both "No Internet" and LG app store errors.

Go to Settings → All Settings → Network → Wi-Fi Connection → Advanced Wi-Fi Settings.
Switch DNS Server from Automatic to Manual.
Enter 8.8.8.8 for Primary and 8.8.4.4 for Secondary.
Select Connect to apply.

Fix 5: Assign a Static IP to the TV

If the router's DHCP pool is exhausted or issuing duplicate addresses:

In Advanced Wi-Fi Settings on the TV, switch IP Address Setting to Manual.
Enter an IP address outside the router's DHCP range (e.g., if DHCP issues 192.168.1.100–200, use 192.168.1.250).
Set Subnet Mask to 255.255.255.0, Gateway to your router's IP (e.g., 192.168.1.1), and DNS as above.

Fix 6: Update LG Firmware via USB (Critical for 2022 Models)

If the TV cannot connect at all, OTA updates are impossible. LG provides firmware files downloadable from a computer.

Visit https://www.lg.com/us/support and enter your TV model number (found on a sticker on the back).
Download the latest firmware ZIP file.
Extract it to the root of a FAT32-formatted USB drive. The file structure must be: LG_DTV/[model]/[firmware].epk
Insert the USB into the TV while it is off, then power on.
Go to Settings → All Settings → General → About This TV → Check for Updates.
The TV will detect the USB firmware and prompt for installation. Do not unplug during this process.

Fix 7: Reset Network Settings Only

This is less destructive than a full factory reset — it only clears network data.

Go to Settings → All Settings → General → Reset to Initial Settings.
Select Network (not "All Settings").
Confirm and allow the TV to restart.
Reconnect to WiFi from scratch.

Fix 8: Full Factory Reset (Last Resort)

If nothing else works, a factory reset clears all corrupted system state.

Go to Settings → All Settings → General → Reset to Initial Settings.
Enter your PIN (default: 0000).
Confirm the reset and wait for the TV to reboot.
Complete initial setup and reconnect to WiFi.

Step 3: Post-Fix Verification

After reconnecting, verify full connectivity:

Settings → All Settings → Network → Network Connection Test — this runs a four-stage check (physical layer, router, internet, LG server).
Open the LG Content Store — if it loads, the connection is fully functional.
Stream a YouTube video to confirm sustained throughput.

If the TV connects but drops after a few minutes, disable band steering on your router and force the TV to the 2.4 GHz band. Band steering (where the router dynamically switches clients between 2.4 and 5 GHz) can cause webOS clients to lose their session.
