Exact questions
Common questions about “LG TV will not connect to Wi-Fi”
Why won't the LG TV connect to Wi-Fi?+
The password, signal or a router setting can block it.
Should I try another band?+
Try 2.4 GHz for range.
Does the TV support both Wi-Fi bands?+
Many LG TVs do, but older ones may only support 2.4 GHz. Check your model's specification.
Should I update the TV?+
Yes. Firmware updates fix many Wi-Fi faults. If the TV cannot get online, use a USB update.
Could the router's security be an issue?+
Some older TVs struggle with newer security modes. Trying WPA2 on the router can help.
Should I try a wired connection?+
If your LG TV has an Ethernet port, plug in a cable to test. If it works wired, the Wi-Fi link or router settings are the cause and can be tuned.
What if the TV connects then drops?+
Drops usually point to signal strength or interference. Move the router closer, avoid placing it near a microwave or cordless phone and check for firmware updates on both the TV and the router.
Should I forget the network on the TV and rejoin it, rather than just retyping the password?+
Yes, if a straightforward retry has already failed once — a forgotten and rejoined network clears a stale saved profile that can keep failing even with a correct password typed again, which a simple retry does not touch.
