How to Fix WiFi Issues on Android TV and Google TV Devices

Android TV and Google TV devices are some of the most popular streaming platforms around, but their WiFi implementations have quirks that trip up a lot of users. The TV might refuse to connect, drop the network every hour, or deliver a fraction of the speed your phone gets on the same couch. The cause is almost never the TV hardware itself — it’s usually a mismatch between the TV’s WiFi adapter and your router’s settings. Work through these fixes in order and you’ll resolve the problem without a factory reset in the vast majority of cases.

Step 1: Restart Both the TV and the Router

Half of all Android TV WiFi problems disappear after a proper power cycle. Do it in this order:

1. Unplug your router from the wall (not just the power button — pull the cord) and wait 30 seconds.
2. Turn off your TV and unplug it from the wall for 30 seconds.
3. Plug the router back in and wait for all its indicator lights to stabilize — usually 60–90 seconds.
4. Plug the TV back in and try reconnecting.

This clears stale DHCP leases on both ends and resets the WiFi driver on the TV, which gets stuck in a bad state more often than you’d expect.

Step 2: Check Signal Strength and Router Placement

Android TV adapters are less powerful than the one in your phone. A signal that looks fine on your smartphone may be marginal for the TV’s smaller antenna. On your TV, go to Settings → Network & Internet and check the signal strength indicator. Anything below “Good” or below −70 dBm will cause buffering and drops.

The router should be within clear line of sight if possible. Every wall adds attenuation — a single concrete or brick wall can cut signal by 15–20 dB. If the TV is far from the router, a WiFi extender or a mesh system node placed in the same room will make a dramatic difference. Keep the router and TV at least 1 meter (3 ft) apart even when they’re in the same room — too close can sometimes cause interference at the receiver.

Step 3: Switch WiFi Bands (2.4 GHz vs 5 GHz)

This is one of the most overlooked fixes. Older Android TV devices (pre-2020) have modest 5 GHz radios that struggle through walls, making 2.4 GHz the better choice at range. Newer Google TV devices handle 5 GHz well but may connect to the wrong band automatically if your router uses a combined SSID.

Try connecting to each band separately. In your router’s admin panel, give the 2.4 GHz and 5 GHz networks different names (e.g., “Home_2G” and “Home_5G”) so you can choose deliberately. If the TV is in the same room as the router, use 5 GHz. If it’s a room or two away, try 2.4 GHz and see if stability improves.

Also verify that your router hasn’t placed the TV on a DFS (Dynamic Frequency Selection) channel on the 5 GHz band — channels 52–144. Android TV adapters handle DFS channels poorly and may drop connection when the router does a radar scan. Switch to non-DFS channels (36, 40, 44, 48, 149, 153, 157, 161) in your router’s wireless settings. See our channel-changing guide for step-by-step instructions.

Step 4: Forget the Network and Reconnect

A corrupted saved network profile can cause the TV to fail authentication silently. The fix is to start fresh:

1. Go to Settings → Network & Internet on the TV.
2. Select your WiFi network, scroll down, and choose Forget.
3. Reconnect by selecting the network and entering the password manually.

On Google TV, the path is Settings → Network & Internet → [Network Name] → Forget. After forgetting, reboot the TV once before reconnecting — this ensures the old credentials are fully cleared from memory.

Step 5: Fix Router Security Mode Incompatibility

This is the single most common cause of Android TV WiFi failures that are hard to diagnose, because the TV connects briefly and then drops, or connects but shows “No Internet.” Android TV adapters have inconsistent WPA3 support. A router set to WPA3-only mode will either refuse the TV entirely or cause repeated disconnections.

In your router’s wireless security settings, change the security mode to WPA2-PSK (AES) or WPA2/WPA3 mixed mode. Avoid WPA3-only, WPA/WPA2 Enterprise, or TKIP encryption. This change affects all devices on the network but is backward-compatible — WPA3-capable devices will still connect securely in mixed mode.

Step 6: Set a Static DNS on the TV

If the TV connects successfully but streaming apps show errors or load slowly, the issue may be DNS resolution rather than bandwidth. Android TV devices occasionally get stuck using a slow or unresponsive DNS server assigned by the router.

Go to Settings → Network & Internet → [Your Network] → IP Settings and switch from DHCP to Static. Keep the same IP address and gateway, but change the DNS entries to:

• DNS 1: 8.8.8.8 (Google)
• DNS 2: 8.8.4.4 (Google)

Alternatively, use 1.1.1.1 and 1.0.0.1 (Cloudflare) for potentially faster resolution. Save the settings and relaunch a streaming app to test.

Step 7: Update the TV System Software

Manufacturers including Sony, Hisense, TCL, and Nvidia regularly push firmware updates that fix WiFi driver bugs. An unpatched TV running old firmware is a common source of mysterious drops and connection failures.

On Google TV: Settings → System → About → System Update. On Android TV: Settings → Device Preferences → About → System Update. If the TV can’t reach the update servers over WiFi (because WiFi isn’t working), connect it via Ethernet temporarily using a USB-C or USB-A to Ethernet adapter — most Android TV devices support wired connections through an OTG adapter.

Step 8: Reduce Wireless Interference

Microwaves, baby monitors, Zigbee smart home hubs, and neighboring WiFi networks all compete on the 2.4 GHz band. If your TV is in a kitchen or near a laundry room, microwave interference can directly cause buffering during cooking. Moving to 5 GHz or switching to a less-congested channel eliminates most interference-related problems. See our full guide on WiFi interference sources for a complete rundown.

Factory Reset (Last Resort)

If nothing else works, a factory reset clears all settings including corrupted network profiles and misconfigured app data. On Google TV: Settings → System → About → Reset → Factory Reset. On Android TV: Settings → Device Preferences → Reset. You’ll need to sign back in to all streaming services, so have your passwords ready. Factory resets fix WiFi issues in a small but real percentage of cases where the problem is a corrupted system partition rather than a configuration error.

Quick Diagnostic Checklist

1. Restart router and TV (unplugged from wall, 30 seconds).
2. Check signal strength in Settings → Network & Internet — move router or add extender if weak.
3. Separate 2.4 GHz and 5 GHz SSIDs; try each band independently.
4. Forget the network profile and reconnect.
5. Set router security to WPA2-PSK (AES) or WPA2/WPA3 mixed.
6. Switch to non-DFS 5 GHz channels (36–48 or 149–161).
7. Set static DNS to 8.8.8.8 / 8.8.4.4 on the TV.
8. Update TV system software via Settings → System Update.
9. Factory reset as a last resort.
