Sony Bravia keeps disconnecting after system update — Wi-Fi, LAN and app issues explained
Technician
A few quick questions so we don’t guess:
• Which model/year is it (Bravia Android TV, Google TV, XR series like X90J/X90K, A80J, etc.)?
• Are you using Wi-Fi or wired LAN (Ethernet)? If Wi-Fi, how far is the router and are you on 2.4 GHz or 5 GHz?
• What was updated recently — the Bravia software/firmware, the router firmware, or both?
• What exactly do you see on screen: “Cannot connect to the Internet”, “Server not found”, network errors like 1107/2203/7003, or apps that say “Network connection lost” while streaming?
The more detail we have, the better we can fix a Sony Bravia that keeps disconnecting from Wi-Fi after an update instead of just factory-resetting everything blindly.
Technician
What usually changes in that situation:
• The router may change Wi-Fi channels, band-steering or security modes, so the Bravia Wi-Fi connection becomes unstable while phones still cope fine.
• The TV firmware update can corrupt the saved Wi-Fi profile or reset some IP/DNS settings, so the TV drops its IP address and can’t reach apps, even though it still shows as “connected”.
• In some cases you’ll see Sony network errors like 1107, 2203 or “Cannot connect to the server”, which basically mean the TV lost the internet link mid-stream.
We’ll:
1) Run the built-in network diagnosis on your Sony Bravia.
2) Reboot and refresh router + TV in the right order.
3) Forget and reconnect Wi-Fi with clean settings.
4) If needed, tweak channels, DNS and IPv6 so your Bravia smart TV stops disconnecting after updates and stays online for streaming.
Technician
Step 1 — Run Sony Bravia network diagnosis
1) On the TV remote, press HOME.
2) Go to Settings → Network & Internet (or Network on some models).
3) Choose Network diagnosis / Check connection and run the test.
4) Note what it says for “Wireless device”, “Local network” and “Internet” — which ones show a red X or failed status.
Step 2 — Power reset modem, router and Sony Bravia
• Unplug the modem and router from power for 30–60 seconds.
• While they’re off, unplug the Bravia TV from the wall (not just standby) for 30 seconds as well.
• Plug in the modem, wait for it to be fully online; then plug in the router; finally plug the TV back in and turn it on.
This sequence forces the TV to renegotiate its connection on a fresh, stable network and often clears Bravia Wi-Fi disconnect issues after an update. After that, we’ll refresh the Wi-Fi profile itself.
Technician
Step 3 — Forget and reconnect Wi-Fi on Sony Bravia
1) On the TV, go to Settings → Network & Internet.
2) Highlight your Wi-Fi network, press the OK / Enter button, then choose Forget network.
3) Turn the TV off and back on, then go to Network & Internet again and reconnect to the same Wi-Fi, carefully re-entering the password.
Step 4 — Check band (2.4 vs 5 GHz) and DNS
• If your router broadcasts 2.4 GHz and 5 GHz under different names, try connecting the Bravia to the band with the stronger signal in that room (often 5 GHz if the router is nearby, 2.4 GHz if it’s far or through walls).
• In Advanced network settings on the TV, set IP to Automatic (DHCP) and, if available, set DNS manually to a reliable public DNS (for example 8.8.8.8) — this sometimes stops “Cannot connect to server” errors on Sony smart TVs.
After reconnecting, use a couple of apps for 20–30 minutes and see whether the Bravia Wi-Fi still disconnects after the update.
Technician
Step 5 — Check router features that upset Bravia
• In the router admin page, look for options like Smart Connect, band steering, Airtime Fairness, AP isolation. Try turning Smart Connect/band steering off so the Bravia stays on one band instead of being bounced between 2.4 and 5 GHz.
• If there’s an option for IPv6, temporarily disable IPv6 on the router LAN side. Some Sony TVs behave better with IPv4-only home networks.
• Fix your Wi-Fi channel instead of “Auto” if you’re in a crowded area — channels 1, 6 or 11 on 2.4 GHz, and a clean channel on 5 GHz, often stabilise Bravia Wi-Fi that keeps dropping.
Step 6 — Correct date & time and reduce interference
• On the TV, set Date & Time to “Automatic via network”. Wrong time can sometimes break app certificates and cause “Cannot connect to server”.
• Make sure the router isn’t buried in a cabinet or right beside thick walls or microwaves — move it slightly higher or closer to the TV if possible.
After these tweaks, test live streaming again. If the Bravia still loses the internet connection while everything else is fine, we’ll look at software updates and, if needed, Ethernet.
Technician
Step 7 — Check for another firmware patch
1) Press HOME → Settings → System → About → System software update (exact names vary slightly).
2) Run “Check for update” and install anything pending. Sony sometimes pushes small patches after a major update that fixes Bravia Wi-Fi connection issues.
Step 8 — Clear streaming apps cache and reset network settings
• Go to Settings → Apps → See all apps, select heavy services like Netflix, YouTube, Disney+, Prime Video.
• For each one, choose Clear cache (avoid “Clear data” unless you’re OK signing in again).
• Then open Settings → System → Restart or simply power the TV off and back on.
• If drops persist, in some Bravia menus you’ll see Network reset or “Reset to factory settings (Network only)” — using that will wipe Wi-Fi/lan settings without erasing apps, which often stops network error 1107 / 2203 loops after updates.
Test again: if you can stream for an evening with no disconnects, your Sony Bravia losing internet after update problem is probably solved.

Preventive tips so updates don’t break things
• Keep the Bravia on a stable main SSID that you rarely rename or change the password on.
• Once every week or two, restart the router and TV on your own schedule instead of waiting for them to misbehave during movie night.
• Leave automatic software updates on, but if you notice a specific update causes drops, you can temporarily turn auto-update off and wait for Sony to release a follow-up patch.
• Avoid too many VPNs or “optimizer” apps on the TV — they can interfere with network stability after firmware changes.
When to use Ethernet or factory reset
• If your layout allows it, a simple Ethernet cable or powerline adapter from router to TV is the most reliable way to stop Bravia Wi-Fi dropping during 4K streaming.
• Consider a full factory data reset if: you still see frequent network errors on a strong connection, apps crash often, and smaller steps (cache clear, network reset, updates) didn’t help. That gives your Sony smart TV a clean start with the latest firmware.
Technician
How to tell if it’s the Bravia vs router/ISP
• Next time the TV shows “Unable to connect to network”, immediately run a speed test on a phone or laptop on the same Wi-Fi.
• If everything else is online and fast, it’s likely a Bravia-specific Wi-Fi problem — then a factory reset can help.
• If phones and laptops also drop or slow down at the same time, it’s more likely the router or ISP (congestion, faulty firmware, signal issues). In that case, talk to your provider about their router or try another one if possible.
A factory reset mainly fixes corrupted settings on the Sony TV after an update. If only this Bravia keeps losing connection while every other device is rock solid, a reset plus a clean setup on a known-good network is often the quickest way to rule out TV-side bugs.
Technician
Quick answer: the accepted fix
Accepted fix when a Sony Bravia keeps losing connection after an update: run the built-in Network diagnosis, then power-reset modem, router and TV. Forget and reconnect your Wi-Fi network on the Bravia, using the most stable 2.4 or 5 GHz band and automatic IP with reliable DNS. Disable aggressive router features like Smart Connect, install any pending Sony firmware patches, and clear cache for streaming apps. If only the TV still drops while other devices are stable, reset network settings or connect the Bravia via Ethernet for a rock-solid link.
Why Sony Bravia disconnects after a firmware or router update
Most Sony Bravia connection problems after an update come down to a mix of router changes and TV software quirks. Router firmware updates can merge 2.4 and 5 GHz networks, change Wi-Fi channels, security modes or DHCP leases, and the TV’s wireless adapter reacts badly even while phones adapt. At the same time a Bravia Android/Google TV update may reset or corrupt saved Wi-Fi profiles, IP/DNS settings or app certificates. The result: the TV shows errors like 1107 or “Cannot connect to server”, or your Sony Bravia smart TV keeps disconnecting from Wi-Fi until you refresh both the network and TV settings.
How to test if your Sony Bravia connection is really fixed
After you’ve applied fixes, leave the Bravia streaming for at least an hour in apps like Netflix, YouTube and Disney+. Watch whether the top-right network icon stays solid and if any “Unable to connect to network” messages appear. When you see a drop, immediately test internet on a phone or laptop on the same Wi-Fi. If everything else is fine, the issue is still TV-side; if all devices slow down, it’s more likely a router or ISP problem. A stable Sony Bravia should play multiple episodes or a full movie without losing Wi-Fi, throwing server errors or kicking you back to the home screen.
Sony Bravia losing connection — quick troubleshooting tips
Most cases are fixed by refreshing the network, tuning router settings and updating the TV.
Quick path: run Network diagnosis on the Sony TV, power-reset modem, router and Bravia, then forget and reconnect your Wi-Fi network. Use the most stable 2.4 or 5 GHz band, set IP to automatic and DNS to a reliable server, and disable router features that bounce devices between bands. Install all available Sony firmware updates, clear cache for streaming apps, and consider Ethernet if Wi-Fi remains unstable. These steps solve the majority of Sony Bravia losing connection after update issues at home.

FAQ
Why did my Sony Bravia start losing connection right after an update?
Updates can change Wi-Fi settings on your router (channel, band steering, security) and reset network components inside the TV. When that happens together, the Sony Bravia may drop its IP address or fail to reach Sony/streaming servers even though Wi-Fi bars look fine. Running network diagnosis, power-resetting everything and reconnecting Wi-Fi with fresh settings usually clears these post-update glitches.
Is 2.4 GHz or 5 GHz better for Sony Bravia Wi-Fi?
Both work, but they’re good at different things. 2.4 GHz travels further and through walls, which can help if your router is far away. 5 GHz is faster and often less crowded, so it’s ideal when the router is in or near the same room. The best way to stop Bravia Wi-Fi disconnects is to connect the TV to whichever band gives you the strongest, most stable signal in network diagnosis.
How do I stop my Sony Bravia from disconnecting from Wi-Fi every day?
Restart your modem, router and TV, then forget and reconnect the Wi-Fi network on the Bravia. Turn off aggressive router features like Smart Connect, fix your Wi-Fi channel, set IP to automatic and DNS to a reliable server, and install all available Sony firmware updates. If the TV is still unstable on wireless, using an Ethernet cable or powerline adapter is the most reliable way to avoid daily disconnects.
When should I factory-reset my Sony Bravia because of connection issues?
Consider a factory reset if your Sony Bravia still loses connection frequently after power-resets, Wi-Fi reconnection, router tweaks, firmware updates and network resets on the TV. If only this TV has problems while every other device is solid, a full reset can clear corrupted settings left over from updates and give you a clean start on the latest software.
