Roku TV losing connection after update — Wi-Fi keeps dropping and internet issues

Technician avatar Technician
Hey! We’ll track down why your Roku TV is losing connection after an update and get it to stay online without you constantly re-entering the Wi-Fi password.
A few quick questions so we know exactly what we’re fixing:
• Brand/model: TCL Roku TV, Hisense Roku TV, onn., Sharp, or another Roku TV brand?
• Are you using Wi-Fi or ethernet, and is it 2.4 GHz, 5 GHz, or a mesh/guest network?
• Did the Roku OS update just install recently and right after that the TV started disconnecting?
• When it drops, do you see a message like “Not connected to the internet”, “Unable to connect to wireless network”, or an error code 014.xx?
• Do other devices (phones, laptops, consoles) stay connected to Wi-Fi when the Roku TV disconnects, or do they also drop?
The more detail we have, the easier it is to fix a Roku TV that keeps disconnecting from Wi-Fi after an update instead of guessing and factory-resetting everything for nothing.
Customer
It’s a 55″ TCL Roku TV, a bit over 2 years old. The problem started right after a recent Roku software update. Almost every time I turn it on, it shows “Not connected to the internet” and sometimes an 014.30 code. I have to go back into Settings > Network and reconnect to my Wi-Fi. It will work for a while, then drop again in the middle of Netflix. All my other devices stay online, so it feels like the Roku TV keeps losing Wi-Fi after the update, not the router.
Technician avatar Technician
Thanks, that’s exactly the type of detail we need. This is a classic pattern: Roku TV losing connection after an OS update while everything else on Wi-Fi is fine.
Typical causes after an update:
• The update corrupted the saved network profile, so the Roku TV won’t stay connected to Wi-Fi and keeps dropping back to “wireless off”.
• The router and Roku disagree on band/channel, especially if you use 5 GHz or a combined SSID on a mesh system.
• Power-saving or “network standby” quirks introduced in the new firmware cause the Roku TV to disconnect from Wi-Fi when idle and not reconnect properly.
• Less often, DNS/DHCP glitches on the router affect only the Roku after its firmware changed.

We’ll go in this order so we don’t waste time:
1) Full restart of Roku TV and router, plus a connection test.
2) Forget and re-add the wireless network to clear bad settings.
3) Run a Network connection reset on the Roku TV (not a full factory reset).
4) Adjust Wi-Fi band/channel and check for extra Roku system updates.
5) Only if it still keeps dropping, we talk about factory reset or involving Roku/TV support.
Customer
Other devices never drop. My phone, laptop, and Xbox all stay connected to the same Wi-Fi network. The router is in the same room as the TV, signal is “Excellent” when I test it on the Roku. It’s just the TV that disconnects randomly, especially after it’s been in standby. Sometimes it shows full bars but apps won’t load and then it says there’s no internet. So yeah, it feels like a Roku TV Wi-Fi issue after the update.
Technician avatar Technician
Got it — strong signal and other devices stable means we can focus on the Roku side without chasing router ghosts first.
Step 1 — Do a true restart of Roku TV and router
1) On the Roku remote, press Home, then go to Settings > System > Power > System restart (or Settings > System > System restart on some TVs) and restart the TV.
2) Unplug your modem/router from power for 30–60 seconds, then plug it back in and wait until Wi-Fi is fully up again.
3) When the network is online, turn the Roku TV back on and let it sit on the Home screen for a minute.
4) Go to Settings > Network > Check connection and see if it passes both “Wireless” and “Internet” tests.

This alone can stabilize a Roku TV that keeps disconnecting from internet after an OS update. Let me know: does the connection test pass, and does it stay online for at least 10–15 minutes of streaming after you do this?
Customer
I restarted both the router and the Roku TV like you said. The network check passed and streaming worked fine for about an hour. But the next day when I turned the TV on, it was back to “Not connected to the internet” again. Sometimes the wireless test passes but the internet test fails. So the Roku TV connection keeps dropping, just not as often as before.
Technician avatar Technician
That tells us the Wi-Fi radio itself still works, but the saved network profile is flaky — very common when a Roku TV starts losing Wi-Fi after a firmware update.
Step 2 — Forget and re-add the Wi-Fi network
1) Go to Settings > Network > Set up connection > Wireless.
2) Highlight your current network name (SSID), press the * key on the remote if available, and choose Forget.
3) Back out, then go again to Set up connection > Wireless and connect fresh, carefully entering the password.

If your router broadcasts both 2.4 GHz and 5 GHz with the same name and you suspect interference, it’s worth briefly testing a different band:
• If you were on 5 GHz, try the 2.4 GHz SSID to see if it stops the Roku TV from dropping connection when you wake it from standby.
• Make sure security is set to WPA2/WPA3 and not some mixed or legacy mode your Roku doesn’t like.

Also, in Settings > System > Power, turn off any “power saving” option that might aggressively put Wi-Fi to sleep. After you’ve forgotten and re-added the network, tell me if the TV connects faster and if it survives at least one power cycle without losing internet.
Customer
I forgot the network and reconnected. I also switched from my 5 GHz SSID to the 2.4 GHz one and disabled the Roku power saving option. It does seem a bit more stable now, but I still had it drop the Wi-Fi once when switching from YouTube to Netflix. It said the wireless connection was good but “no internet”. So the Roku TV still randomly loses internet after the update, just not as frequently.
Technician avatar Technician
Good, we’ve reduced how often it happens — now we go one level deeper and reset just the Roku network stack.
Step 3 — Run a Network connection reset on Roku TV
1) Press Home on the remote.
2) Go to Settings > System > Advanced system settings.
3) Choose Network connection reset (not “Factory reset”).
4) Confirm Reset connection and let the TV reboot.
5) When it starts back up, go to Settings > Network > Set up connection and reconnect to your preferred Wi-Fi again.

This clears hidden connection data and often fixes a Roku TV that keeps disconnecting from Wi-Fi after an OS update without erasing your apps/channels.

After the reset and reconnect, stream something for 20–30 minutes and then also test again after the TV wakes from standby. If it still drops, we’ll test with ethernet and look at router-side tweaks.
Customer
I did the Network connection reset and set the Wi-Fi back up. So far it’s better — I watched for about 45 minutes with no disconnects. But earlier today after the TV had been off for a few hours, it came back on with “Not connected to the internet” again until I hit Retry. It’s definitely improved, but the Roku TV still sometimes loses the Wi-Fi connection after the update.
Technician avatar Technician
Understood — we’ve ruled out a lot of software junk on the Roku itself. Now we want to see if this is strictly wireless behaviour.
Step 4 — Test with ethernet (if your Roku TV has a LAN port)
• Temporarily run an ethernet cable from the router to the Roku TV.
• Go to Settings > Network > Set up connection > Wired and let it connect.
• Stream for a bit and see if the TV still loses connection or if it’s rock solid over cable.

If ethernet is stable but Wi-Fi isn’t, that confirms the issue is the wireless link after the update, not your internet service as a whole.

On the router side, there are a few tweaks that often help when a Roku TV keeps dropping internet connection:
• Make sure the router firmware is up to date.
• For 2.4 GHz, set wireless mode to b/g/n or g/n only (not legacy mixed modes).
• If your router lets you pick a channel, try a less congested one like 1, 6, or 11 instead of “Auto”.
• Temporarily disable any VPN, parental controls, or MAC filtering rules to see if they’re interfering with the Roku after the update.

Let me know how the ethernet test behaves and if your router offers any of those settings.
Customer
I tried a long ethernet cable from the router to the TV and it was perfectly stable for several hours. No disconnects at all. So wired is fine, but I can’t leave the cable across the room permanently. I changed the 2.4 GHz mode to b/g/n and set the channel manually like you suggested. The Wi-Fi seems more reliable now, but I’m still nervous because this all started only after the Roku OS update.
Technician avatar Technician
The ethernet test is actually good news: it proves the TV and the Roku firmware can stay online, so we’re down to Wi-Fi behaviour plus that update.
A few more fine-tuning steps that help when a Roku TV keeps disconnecting from Wi-Fi after a software update:
• On the Roku TV, go to Settings > System > System update and run Check now — sometimes Roku pushes quiet patches after reporting Wi-Fi bugs.
• In Settings > Network > About, confirm signal strength shows “Good” or “Excellent” near 4–5 bars.
• If your mesh or router supports it, give the Roku TV its own SSID (or a dedicated 2.4 GHz network) so it’s not bouncing between nodes or bands.
• Move the router or a mesh node a little closer and avoid putting it behind the TV, inside a cabinet, or next to a microwave/cordless phone — those make Roku TVs drop Wi-Fi more often.

If after all of this the TV still occasionally loses connection, we’re left with two “last step” options: a factory reset, or opening a case with Roku/TCL about a Roku TV losing connection after update so they can log it as a firmware issue.
Customer
Would a factory reset actually help in this situation? I really don’t want to reinstall all my apps and log back into everything if it won’t change anything. Also, is there any way to go back to the previous Roku software version, or am I stuck with this one causing the Roku TV to lose Wi-Fi?
Technician avatar Technician
Great questions — you’re thinking about it exactly the right way.
When a factory reset is worth trying for Roku Wi-Fi issues
• You’ve already restarted the TV and router, forgotten/re-added Wi-Fi, run a Network connection reset, and installed any follow-up updates.
• The TV still loses connection after every update or power cycle, even with strong signal and stable router.

In that case, a factory reset can clear deeper config corruption:
• Go to Settings > System > Advanced system settings > Factory reset.
• Follow the on-screen steps to wipe the TV, then set it back up, connect to Wi-Fi, and test streaming before reinstalling a ton of channels.

As for rolling back a Roku TV update, there’s no official “go back” button. Roku usually fixes bad updates by pushing a newer build, not by letting users downgrade. That’s why it’s useful to document that your Roku TV started losing connection after a specific OS version and open a ticket with Roku or the TV manufacturer. They can sometimes push a patch or confirm it’s a known issue.

My rule of thumb: if a network connection reset and router tweaks make it mostly stable, I avoid factory reset unless the disconnects are still happening daily.
Customer
After the network connection reset, changing the router channel, turning off power saving, and sticking to the 2.4 GHz network, it’s now been a few days with no drops. The Roku TV wakes up connected and streaming works normally again. If it starts losing the connection after another update, I’ll try a factory reset or contact Roku/TCL support with everything we did. Thanks for walking me through fixing my Roku TV losing connection after update issue.
Technician avatar Technician
Summary: when a Roku TV keeps disconnecting from Wi-Fi after an update, start with a proper restart of the TV and router, then forget and re-add the wireless network. Run a Network connection reset under Advanced system settings, switch bands if needed (2.4 vs 5 GHz), and tweak router settings so the signal is strong and stable. If ethernet is rock solid but Wi-Fi isn’t, that points to wireless config or firmware quirks rather than bad internet. Only if it still keeps losing connection do you move to a full factory reset or open a case with Roku/your TV brand. Want someone to walk through the exact menu path for your model and router?

Quick answer: the accepted fix

Accepted first fix when a Roku TV is losing connection after an update or keeps disconnecting from Wi-Fi: restart both the Roku TV and your modem/router, then go to Settings > Network > Check connection to verify wireless and internet status. Forget and reconnect to your Wi-Fi under Settings > Network > Set up connection, then run Settings > System > Advanced system settings > Network connection reset and reconnect again. Switch to a more stable band (often 2.4 GHz), update Roku software under Settings > System > System update, and adjust router channel/mode. In many cases this stops a Roku TV from dropping internet without needing a full factory reset.

Why Roku TV starts losing connection after an update

Most Roku TV losing connection after update cases come down to a handful of repeat problems. The update can corrupt the saved network profile, so the TV “forgets” how to reconnect and the Roku TV won’t stay connected to Wi-Fi. Router changes, band steering, or crowded 5 GHz channels can cause random drops even when signal looks “Excellent”. Power-saving tweaks in new firmware sometimes disconnect Wi-Fi in standby and fail to reconnect properly. Less often, DNS or DHCP issues on the router affect only the Roku after its OS changes. That’s why the best approach is to reset the Roku network stack, forget and reconnect Wi-Fi, and then tune router settings before assuming it’s a hardware failure.

How to test if your Roku TV connection is truly fixed

After you’ve applied the steps, don’t just check if it loads one app once. Properly test your Roku TV Wi-Fi connection. Run Settings > Network > Check connection and confirm both “Wireless” and “Internet” show as connected. Stream from at least two different channels (for example, Netflix and YouTube) for 20–30 minutes and see if the Roku TV keeps disconnecting from the internet. Then turn the TV off, leave it in standby for a few hours, power it back on, and check if it wakes up still online. If it survives streaming, app switches, and wake-from-sleep without errors like “Not connected” or 014 codes, you’ve likely solved the Roku TV losing connection after update issue. If the drops return, it’s time to look at ethernet, mesh placement, or contact Roku/TV support.

Roku TV losing connection after update — quick troubleshooting tips

Most cases are fixed by resetting the Roku network connection and tuning Wi-Fi settings.

Quick path: restart your Roku TV and router, then forget and reconnect to Wi-Fi. Run Network connection reset under Advanced system settings and set the TV back up on a stable 2.4 GHz or 5 GHz network. Update Roku software to the latest build, and adjust your router’s channel and wireless mode to reduce interference. Avoid random secret menus or third-party “Wi-Fi booster” tricks — they rarely fix a Roku TV that keeps dropping internet and can make things worse. If your TV still loses connection after every update, document the OS version, error messages, and what you’ve tried, then contact Roku or your TV manufacturer with those details.

FAQ

Why is my Roku TV losing connection after an update?

A Roku TV losing connection after an update is usually caused by corrupted network settings, band/channel changes that make Wi-Fi unstable, or new power-saving behaviour that disconnects wireless in standby. Sometimes DNS or DHCP issues between the router and Roku mean the TV shows full bars but no internet, so apps fail to load until you reconnect.

What is the first thing to try when Roku TV keeps disconnecting from Wi-Fi?

Restart both the Roku TV and your modem/router, then go to Settings > Network > Check connection. If it still keeps disconnecting from Wi-Fi, forget your wireless network, reconnect with the correct password, and run Settings > System > Advanced system settings > Network connection reset before setting the network up again.

How do I stop my Roku TV from dropping internet connection?

To stop a Roku TV from dropping internet connection, use a stable 2.4 GHz or 5 GHz network with good signal, update the Roku software, and set your router to b/g/n wireless modes with a clean channel. Move the router closer or use a mesh node, avoid VPNs or strict MAC filtering for the TV, and if problems persist, test ethernet to confirm it’s only Wi-Fi misbehaving.

When should I factory reset my Roku TV for Wi-Fi problems?

Consider a factory reset only after you’ve restarted the Roku TV and router, forgotten and re-added Wi-Fi, run a Network connection reset, and installed all available updates. If your Roku TV still loses connection after every update even with strong signal and router tweaks, a factory reset can clear deeper software issues. If that doesn’t help, contact Roku or your TV manufacturer to check for known firmware bugs or hardware faults.
