Sony Bravia keeps disconnecting after software update — Wi-Fi, LAN, app and server issues

Technician avatar Technician
Hey! We’ll track down why your Sony Bravia is losing connection after an update and stop the Wi-Fi from dropping all the time. A few quick questions so we don’t guess:
• Exact Sony Bravia model (Android TV or Google TV) and roughly what year?
• Is the TV on Wi-Fi (2.4/5 GHz) or plugged in with an Ethernet (LAN) cable?
• What just updated — the Bravia system software, the router firmware, or both?
• Symptoms: “Wi-Fi disconnected”, “could not connect to the Internet”, “cannot connect to server”, apps like Netflix/YouTube saying “network error” or “TV offline”?
• When you run the TV’s Network Status / Network Diagnosis, which parts fail (TV to router, or router to Internet)?
The more detail we have, the easier it is to fix a Sony Bravia that keeps disconnecting after an update instead of just rebooting everything randomly.
Customer
It’s a Sony Bravia Android TV from 2021. After a software update last week, the TV keeps dropping Wi-Fi. Sometimes it shows the Wi-Fi icon with an exclamation mark, sometimes it says “could not connect to the Internet”. Netflix and YouTube report network errors and say the Bravia is offline, but my phone and laptop work fine on the same router.

Got it — very typical of a Sony Bravia losing connection after a system update.
What usually changes after a TV or router update:
• The TV’s network stack gets updated (new IPv6, DNS or Wi-Fi drivers) and doesn’t like some router settings.
• The router enables features like band steering, new security modes or new DNS, so the Bravia Wi-Fi connection becomes unstable while other devices are fine.
• Cached network info on the TV conflicts with new firmware, so it flips between “online” and “cannot connect to server”.

We’ll:
1) Power-reset the Bravia and router properly (not just standby).
2) Run the built-in Network Status / Network Diagnosis on the Sony TV to see exactly where the connection fails.
3) Cleanly reconnect Wi-Fi (or LAN) and, if needed, tweak advanced settings like IPv6 and DNS so the Sony Bravia network stays connected after updates.
Customer
I did a simple restart on both the TV and router but nothing fancy. When I run Network Status, sometimes I get OK, OK, Failed on the last step. Other times it just says “Wi-Fi connection failed”. The router is dual-band with one combined SSID. The TV is in the same room as the router, so the signal should be strong.
Technician avatar Technician
Perfect, the OK / OK / Failed pattern means the Sony Bravia talks to your router but the router/TV combo can’t reliably reach the Internet or DNS servers.
Step 1 — Do a proper Sony Bravia power reset
• With the TV on, unplug it from the wall for 2–3 minutes, then plug it back in and turn it on.
• Alternatively, hold the POWER button on the remote until “Power off” appears → wait → turn it back on.

Step 2 — Restart the router
• Turn the router off, wait 30 seconds, turn it back on and wait until all lights stabilise.

Step 3 — Run Network Status / Network Diagnosis again
On most Sony Bravia Android / Google TV models:
• Settings → Network & Internet → Network Status → Check Connection
Make a note of whether it fails at “TV to router” or “router to Internet”. That tells us if this is a local Wi-Fi problem or more of a DNS/IPv6 issue that often appears after a Bravia software update.
Customer
After doing the full power reset, the Network Status test now sometimes passes (OK, OK, OK), but a bit later Netflix still shows a network error and the TV drops back to “not connected”. The combined SSID is just my normal home Wi-Fi; I haven’t changed the name or password recently.
Technician avatar Technician
That points to the classic Sony Bravia Wi-Fi dropping after update problem where brief tests pass but streaming apps fail or time out.
Let’s refresh the TV’s Wi-Fi profile and stabilise the connection.
Step 4 — Forget and reconnect Wi-Fi on the Bravia
1) On the TV: Settings → Network & Internet.
2) Highlight your home network → choose Forget network (or Remove / Delete).
3) Turn Wi-Fi OFF, wait 10 seconds, then turn Wi-Fi ON again.
4) Select your network, re-enter the Wi-Fi password carefully (watch 0 vs O, 1 vs l/I).
5) If your router allows it, try connecting the TV to a dedicated 2.4 GHz SSID instead of an auto 5 GHz band. Many Bravia sets are more stable on 2.4 GHz for Wi-Fi range.

Step 5 — Check IP settings, DNS and IPv6
• In Network & Internet → Advanced, ensure IP settings are Automatic (DHCP).
• If there’s an IPv6 toggle, try turning IPv6 OFF so the TV uses IPv4 only.
• Optionally set custom DNS (e.g. Google DNS 8.8.8.8 / 8.8.4.4) if your ISP DNS is flaky after the update.
These small tweaks often stop a Sony Bravia from losing connection after an Android / Google TV update.
Customer
I turned off IPv6 and rejoined Wi-Fi. It works better but I still get random disconnects, especially in Prime Video. I tried a LAN cable as a test and the Ethernet connection works for a while, then the TV shows “cannot connect to server” again even though Network Status says OK, OK, OK.
Technician avatar Technician
If both Wi-Fi and LAN show OK, OK, OK but apps still say “cannot connect to server”, we’re past raw connectivity. That’s more of an app / certificate / date & time issue that appears after updates.
Step 6 — Confirm date, time and app updates
• Go to Settings → System → Date & time and enable Automatic date & time from network.
• Open the Google Play Store on the TV → Manage apps & games → update streaming apps and system components.

Step 7 — Clear cache / data for a problem app
For Prime Video (repeat for any app that fails):
• Settings → Apps → See all apps → Prime Video → Force stop → Clear cache → Clear data → reopen the app and sign in again.

If multiple apps show similar network errors even though the network test passes, we may need to reset just the network settings on your Sony Bravia next.
Customer
Before the update everything was solid, so I’m worried this software version is just buggy. Is there any way to roll back the Sony Bravia firmware update, or should I just wait for another update to fix the Wi-Fi disconnects?
Technician avatar Technician
Sony generally doesn’t let you roll back a Bravia system update, so the trick is to stabilise this version and then keep an eye out for the next patch.
Before a full factory reset, try a network-only reset:
• On many models: Settings → System → About → Reset → Network settings reset (or similar wording).
• This wipes saved Wi-Fi/LAN profiles and returns network options to default, without touching your apps and accounts.

After the network reset:
• Reboot the TV.
• Reconnect to your main Wi-Fi (ideally 2.4 GHz) or LAN and run Network Status again.
• Make sure the router isn’t doing MAC filtering, parental controls or blocking the TV’s IP.

If the Sony Bravia still keeps losing connection after the network reset, the next step is a full factory reset of the TV itself.
Customer
If I do a full factory reset, do I lose all accounts and apps on the Bravia? And will that actually help with the TV disconnecting after updates, or is it more of a last resort?
Technician avatar Technician
Good question. A factory reset on a Sony Bravia is a bit of a nuclear option, but it can definitely fix weird network behaviour left over after big updates.
What a factory reset does
• Removes Google accounts and app logins from the TV.
• Clears cached data, old network configs and any corrupted settings that might cause Bravia Wi-Fi or LAN to drop.
• Keeps the current firmware version — it doesn’t downgrade, but it gives that version a clean slate.

When it’s worth doing
• You’ve tried power resets, network diagnosis, forget/reconnect Wi-Fi, IPv6 changes and network-only reset.
• Network Status keeps flipping between OK and Failed after an update, even on a wired connection.

If we go that route, I’ll walk you through prepping (noting your apps, logins) and the exact menu path for your Sony Bravia model so you don’t miss anything important.
Customer
I’ve also noticed the TV seems to lose connection mostly after it’s been idle or in standby for a while. When I turn it on, it takes a long time to reconnect or shows “Wi-Fi not available”. Could this be some power saving thing that changed with the update?
Technician avatar Technician
Yes, that fits. Some Bravia updates tweak power saving and Wi-Fi standby behaviour, so the TV disconnects too aggressively when it’s idle.
Step 8 — Check Eco / Power saving settings
• Go to Settings → Device Preferences / System → Power / Eco (exact names vary).
• Turn OFF overly aggressive options like “Wi-Fi power saving”, deep sleep, or quick-off modes that cut network in standby.

Step 9 — Enable “Keep Wi-Fi on in standby” / Remote start
• In Network & Internet or Power settings, look for options such as “Keep Wi-Fi on in standby” or “Remote start” and set them to ON or Auto.
• This lets the Sony Bravia stay connected to Wi-Fi so apps and updates don’t have to reconnect from scratch every time you wake the TV.

Combined with the earlier steps (IPv6 off, clean Wi-Fi profile, network diagnosis), this usually stops a Bravia that keeps losing connection after updates.
Customer
After turning off IPv6, forgetting and re-adding Wi-Fi, and changing the power saving settings, it’s been stable all day. Network Status is OK across the board and my Sony Bravia stays connected even after standby. Streaming apps work normally again. Thanks!

Summary: when a Sony Bravia keeps losing connection after an update, the winning combo is: proper power reset of TV and router, run the built-in Network Status / Network Diagnosis, forget and reconnect Wi-Fi (or LAN), then adjust IP, DNS and IPv6 options. If apps still show “cannot connect to server”, clear their cache or reset network settings, and only then consider a factory reset. Still stuck on a specific error code or menu path? Open the chat and an expert will walk through your Sony Bravia step by step.

Quick answer: the accepted fix

Accepted fix when a Sony Bravia loses connection after an update: perform a full power reset of the TV and router, then run Network Status / Network Diagnosis. Forget and reconnect your Wi-Fi (ideally 2.4 GHz) or LAN, disable IPv6 if available, and keep IP settings on Automatic. If Network Status shows OK but apps still say “cannot connect to server”, reset network settings and clear app cache until the TV stays online.

Why Sony Bravia disconnects after a firmware or router update

Most Sony Bravia connection problems after an update come down to three things: new TV firmware changing the network stack, router settings changing, or outdated app/certificate data. A software update can enable IPv6, new DNS or Wi-Fi drivers, while router updates may change security modes, DNS, or band steering. The result is a Bravia that drops Wi-Fi or LAN, shows “could not connect to the Internet” or “cannot connect to server”, or only passes part of the Network Status test. Cleaning up network profiles, disabling problematic options and re-running diagnosis usually reveals whether the failure is between TV and router or router and Internet.

How to test if your Sony Bravia connection is really fixed

After changing settings, leave your Sony Bravia on for a while and open multiple apps (YouTube, Netflix, Prime Video, Disney+). Run the Network Status / Network Diagnosis test and confirm it shows OK for TV, local network and Internet. Put the TV in standby for 10–15 minutes and wake it to see whether Wi-Fi reconnects instantly or still shows “Wi-Fi not available” or “network error”. If only one app fails while others work, it’s usually an app-specific or service issue. If many apps fail and the Bravia repeatedly loses Wi-Fi or LAN after an update, look again at router firmware, IPv6, DNS and power-saving settings.

Sony Bravia losing connection — quick troubleshooting tips

Most cases are fixed by running Network Status, refreshing Wi-Fi and adjusting IPv6/DNS.

Quick path: perform a full power reset on the TV and router, then run the built-in Network Status / Network Diagnosis. Forget and reconnect your Wi-Fi network, preferably on a stable 2.4 GHz band, or test with a wired LAN cable. Turn off IPv6 if the Bravia started disconnecting after an update, keep IP on DHCP, and set simple DNS if needed. Check date and time, update apps, and reset network settings if errors persist. If your Sony Bravia still keeps disconnecting from Wi-Fi or LAN, a guided factory reset with an expert is usually the fastest way to get back to a stable, always-online TV.

FAQ

Why did my Sony Bravia start losing connection right after an update?

Updates can change network drivers, IPv6 and DNS settings or reset Wi-Fi behaviour. Your Sony Bravia may then drop Wi-Fi, show “could not connect to the Internet” or “cannot connect to server” until you power-reset the TV and router, re-run Network Status, and refresh the Wi-Fi/LAN configuration.

Is Sony Bravia better on Wi-Fi or wired LAN?

Both work, but a wired LAN (Ethernet) connection is usually more stable for 4K streaming. If you must use Wi-Fi, a strong 2.4 GHz or 5 GHz signal with clear line-of-sight to the router and simple security (WPA2-PSK) helps prevent the TV from disconnecting after software updates.

How do I stop my Sony Bravia from disconnecting every day?

Run Network Status, power-reset your TV and router, then forget and reconnect Wi-Fi or LAN. Disable IPv6 if it started after an update, keep IP on Automatic, and turn off aggressive power-saving options that cut Wi-Fi in standby. Reset network settings if the TV still shows recurring network errors.

When should I factory-reset my Sony Bravia for connection issues?

If your Bravia still loses connection after power resets, network diagnosis, Wi-Fi/LAN refresh, IPv6 changes and a network-only reset, a full factory reset can clear corrupted settings from previous firmware. It removes accounts and app data but often fixes persistent Wi-Fi or LAN dropouts.
