Roku TV keeps disconnecting from Wi-Fi — signal, router, and software problems explained

Technician avatar Technician
Hey! We’ll track down why your Roku TV keeps disconnecting from Wi-Fi and get it to stay online. I just need a few details so we don’t guess:
• Exact model: TCL Roku TV, Hisense Roku TV, Onn, Roku Express/Stick/Ultra plugged into a TV?
• What does it say under Settings → Network when it drops — “not connected”, “excellent signal but no internet”, or specific error codes like 009, 014.40, 014.50?
• How often does the Roku TV lose connection — only after being idle, every few minutes while streaming, or only after power-cycling the TV or router?
• Other devices (phones, laptops, smart TVs) on the same network: do they stay connected, or do they also drop?
The more we know up front, the easier it is to fix a Roku TV that keeps dropping Wi-Fi instead of just rebooting everything over and over.
Customer
It’s a TCL Roku TV in the living room. For the last week the Roku TV keeps disconnecting from Wi-Fi. Netflix or YouTube will play for a bit, then freeze and show that it’s not connected to the internet. Network test sometimes says “wireless connection: good, internet connection: not connected”. My phone and laptop on the same Wi-Fi work fine.

Got it — classic case of a Roku TV randomly disconnecting from Wi-Fi while everything else is fine.
Typical causes:
• Weak or fluctuating wireless signal at the TV, even when the phone in the same room looks okay.
• Router and Roku fighting over 2.4 GHz vs 5 GHz bands, channels, or power-saving settings.
• The Roku TV’s network stack gets “stuck” after an update and needs a network connection reset instead of a simple restart.
• In a few cases, a flaky router feature (MAC filtering, parental controls, DNS) kicks the Roku off the internet but leaves other devices alone.

We’ll:
1) Check Wi-Fi strength and errors directly on the Roku TV.
2) Restart and, if needed, reset the Roku TV network connection so it negotiates cleanly with the router.
3) Adjust router and band settings so the Roku stops disconnecting every time the signal changes a bit.
If the TV is still dropping, we’ll look at power, cabling, and a backup plan using Ethernet where possible.
Customer
Signal strength usually shows “good” or “excellent”. I can reconnect and it works again for a while, then the Roku TV loses internet mid-movie. Sometimes it even kicks me back to the home screen saying “not connected” even though the router is only one room away.
Technician avatar Technician
Even with “good” signal, little drops can make a Roku TV disconnect from Wi-Fi repeatedly. Let’s stabilise the basics first — almost every Roku Wi-Fi issue starts here.
Step 1 — Run Roku’s own connection test
1) On the Roku TV, go to Settings → Network → Check connection.
2) Note: does it show problems on wireless, internet, or both?
3) If you see messages about poor wireless signal or “could not reach internet”, that points at signal or router issues rather than the apps themselves.

Step 2 — Restart router and Roku TV properly
• Unplug your modem and router from power for 30 seconds, then plug them back in and wait until Wi-Fi is back.
• On the Roku TV, go to Settings → System → Power → System restart (or just System restart on some models).

This alone stops random drops for many people whose Roku keeps disconnecting from Wi-Fi. If the TV keeps dropping after that, we’ll go deeper into network reset and band settings.
Customer
I’ve done simple restarts before and it always comes back, but the Roku TV keeps losing connection again later. I haven’t done a full network reset on the Roku yet or changed router settings. I’m not super technical so I don’t want to break anything.
Technician avatar Technician
Totally fair — we’ll use the safe options Roku and router makers actually recommend.
Step 3 — Use Roku’s Network connection reset
1) On the Roku TV, go to Settings → System → Advanced system settings → Network connection reset.
2) Choose Reset connection. The TV will restart and forget Wi-Fi details.
3) When it comes back, go to Settings → Network → Set up connection → Wireless and reconnect to your main Wi-Fi.

Step 4 — Try 2.4 GHz first for stability
• If your router shows both HomeWiFi_2G (2.4 GHz) and HomeWiFi_5G (5 GHz), connect the Roku TV to the 2.4 GHz network first — it usually penetrates walls better and is more stable for streaming.
• Avoid guest networks or hotspot names that may have extra restrictions.

This network reset often fixes the “Roku TV immediately disconnects after connecting” problem and makes Wi-Fi drops a lot less frequent.
Customer
I did the network connection reset and put it on the 2.4 GHz SSID. It seems better, but I still had one disconnect tonight where the Roku TV dropped the internet and then reconnected by itself a minute later. Could that be something with the router or placement?
Technician avatar Technician
Yes, even with a good router, placement and interference can make a Roku TV keep dropping its Wi-Fi signal.
Step 5 — Improve router and Roku TV placement
• Put the router as high and as central as possible — not on the floor, not inside a metal cabinet.
• Avoid putting the Roku TV or router right next to thick walls, fridges, microwaves, or cordless phone bases.
• If possible, rotate the TV or router slightly — sometimes a few inches or a different angle gives the Roku a cleaner signal.

Step 6 — Check router wireless settings
• Log into the router and check the 2.4 GHz channel — channels 1, 6 or 11 are usually the most reliable.
• Make sure security is set to a standard mode like WPA2-PSK (AES).
• If MAC filtering or parental controls are on, confirm the Roku TV’s MAC address is allowed, or temporarily turn those features off to test.

After these tweaks, watch if the Roku TV keeps disconnecting at the same times of day or if the drops stop entirely.
Customer
Router is in the hallway, not too far. I can’t really move it much more, but I did change the channel to 1 and reboot everything. The TV stayed online longer, but I’ve also seen it disconnect overnight and show as “not connected” in the morning until I run the Roku network check again.
Technician avatar Technician
Understood. That pattern — Roku TV disconnecting when idle or overnight — can be a mix of power and software quirks.
Step 7 — Adjust Roku TV power settings
• Go to Settings → System → Power.
• If there’s an option like Auto power savings or “Turn off after 4 hours”, try turning it off temporarily.
• This stops the Roku from going into a deep sleep that sometimes leads to Wi-Fi failing to reconnect properly.

Step 8 — Consider Ethernet (if your Roku TV supports it)
• Some Roku TVs have an Ethernet port. If yours does and you can run a cable from the router, wired connection is the most reliable way to stop “Roku keeps disconnecting” problems.
• Go to Settings → Network → Set up connection → Wired and let it auto-detect.

If you can’t use Ethernet, we’ll lean on one more powerful option — a full network reset on the router and a firmware check on the Roku TV.
Customer
I don’t have Ethernet at the TV, so Wi-Fi is my only option. I can turn off auto power saving. If the Roku still keeps disconnecting after that, what’s next? Is a factory reset of the TV worth it or is that overkill?
Technician avatar Technician
Great question — we’ll try lighter fixes first, then talk about when a reset makes sense.
Step 9 — Check for Roku TV software updates
1) Go to Settings → System → System update → Check now.
2) Install any available Roku OS update, then restart the TV.
Many releases include fixes for Roku TVs losing Wi-Fi or showing error 009/014.xx.

When to consider a factory reset
• The Roku TV keeps disconnecting every day even after network reset, router tweaks, and updates.
• Other weird behaviour shows up — apps crashing, random restarts, menus freezing.
• You’ve had the same Wi-Fi issues across multiple routers or locations.

If we go that route we’d use Settings → System → Advanced system settings → Factory reset, then set up the Roku TV and Wi-Fi from scratch. It’s more work but can clear corrupted network data that nothing else fixes.
Customer
I updated the software and disabled auto power savings. So far the Roku TV is staying connected. If it starts dropping again, I might try the full reset, but at least now I understand what’s going on instead of just guessing.
Technician avatar Technician
That’s a win already. A couple of extra tips so your Roku TV doesn’t keep disconnecting from Wi-Fi in the future:
• If you have a mesh Wi-Fi system, try locking the Roku TV to the nearest node or turning off fancy roaming features that aggressively hand devices between access points.
• On some ISP-supplied routers, turning off “smart connect” and giving 2.4 GHz and 5 GHz separate names helps the Roku stay on the stronger band.
• Keep the router firmware updated — connectivity bugs are pretty common and newer versions often fix streaming devices dropping off the network.
If things get weird again (error codes, constant disconnects, only Roku affected), an expert can also walk you through DHCP reservation or DNS changes tailored to your exact router model.
Customer
After the network connection reset, channel change, and update, it’s been solid for a couple of days. No more buffering or “not connected” messages — the Roku TV finally stays connected to Wi-Fi. Thanks for breaking down all the steps.
Technician avatar Technician
Summary: when a Roku TV keeps disconnecting from Wi-Fi, start with Roku’s own tools — run a connection test, then restart the TV and router. If it still drops, use Network connection reset, reconnect on 2.4 GHz, and improve router placement and wireless channel. Update Roku OS and loosen any router filters that might be kicking the TV off. If drops continue, a full factory reset or Ethernet (if available) usually solves even stubborn cases.

Quick answer: the accepted fix

Accepted fix when a Roku TV keeps disconnecting from Wi-Fi: on the TV, run Settings → Network → Check connection, then restart both the Roku and router. Use Settings → System → Advanced system settings → Network connection reset, reconnect to a stable 2.4 GHz network, and set a clear wireless channel (1, 6, or 11) on the router. Disable aggressive power saving on the Roku TV and install any Roku OS updates. If the TV still loses connection, consider Ethernet where possible or a full factory reset as a last resort.

Why Roku TV keeps disconnecting from Wi-Fi or internet

Most Roku TV Wi-Fi disconnect problems trace back to three things: marginal wireless signal, router configuration, or software glitches. If the Roku shows good signal but no internet, your router may be struggling with DNS, channel congestion, or advanced features such as MAC filtering and parental controls. When a TCL Roku TV or Hisense Roku TV keeps dropping Wi-Fi only while other devices stay online, it can be due to outdated Roku OS, power-saving modes that don’t wake the network correctly, or cached network data that needs a connection reset. Understanding which of these patterns you see on screen (error codes 009, 014.40, 014.50, “not connected”, “excellent signal but no internet”) helps you choose the most effective fix.

How to test if your Roku TV connection is really fixed

After you tweak the network, don’t just assume it’s fixed — test your Roku TV connection. Run the built-in check under Settings → Network → Check connection and confirm both wireless and internet show as “excellent” or “good”. Stream a show on Netflix or YouTube for at least 20–30 minutes, then pause and resume to see if the Roku TV stays connected. Turn the TV off for a while, then back on the next day and check whether it reconnects automatically without having to re-enter Wi-Fi details. If only the Roku TV loses Wi-Fi while your phone in the same room stays online, you still have a Roku-specific issue; if the whole network slows or drops, the router or ISP connection needs more attention.

Roku TV keeps disconnecting — quick troubleshooting tips

Most cases are solved by a network connection reset, better Wi-Fi channel, and a Roku OS update.

Quick path: start on the TV with Settings → Network → Check connection to see if the problem is wireless or internet. Restart both the router and Roku TV, then use Network connection reset so the Roku forgets old Wi-Fi settings. Reconnect to a 2.4 GHz network with a clear channel and keep the router in an open, central spot. Turn off aggressive power saving, install any pending updates, and watch whether the Roku TV still disconnects from Wi-Fi. If you continue to see error 009 or 014.xx, an expert can look at your exact router model, DNS and advanced settings to stabilise things.

FAQ

Why does my Roku TV keep disconnecting from Wi-Fi?

A Roku TV that keeps disconnecting from Wi-Fi usually has either a weak wireless signal, router settings that conflict with Roku, or a software glitch on the TV. Common triggers include crowded channels, 2.4/5 GHz band steering, outdated Roku OS, or cached network data. Running a network check, restarting the router and Roku, using network connection reset, and connecting to a stable 2.4 GHz network fixes most cases.

How do I stop my Roku TV from dropping internet during streaming?

If your Roku TV drops internet while streaming, first restart the router and TV, then use Settings → System → Advanced system settings → Network connection reset on the Roku. Reconnect to Wi-Fi, preferably on 2.4 GHz with a clear channel. Keep the router in an open area and update Roku OS. If possible, use Ethernet for a wired connection, which is far more stable for long streaming sessions.

What do Roku error codes 009 and 014.40 mean?

Error 009 on Roku usually means the TV is connected to your wireless network but cannot reach the internet. Error 014.40/014.50 generally indicates problems connecting to the wireless network itself, often due to password, security mode, or signal strength. Restarting the router, re-entering the Wi-Fi password, and using Roku’s network connection reset are common fixes.

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

Consider a Roku TV factory reset only after you’ve tried connection tests, network connection reset, router restarts, and Roku OS updates, and the TV still disconnects daily. A factory reset wipes channels and settings, but it can clear deeply corrupted network data. Use it as a last resort, and be prepared to sign back into your streaming apps afterward.
