My TV doesn't know my router's wi-fi password.

My TV thinks it's January 1st 1970.

And so it thinks it is fairly new, then, and doesn't require any tubes replaced. Should that change, it will let you know.

My TV isn't even connected to power

Every time anything asks for a DOB or anything like that, I enter the earliest date their system allows. Been doing it for decades.

I guess that might make me more trackable?

Heh. Steam thinks I'm 126.

At least you could get some interesting ads. Do you want to participate in a longevity study?

I've said it before on HN a long time ago but I'll repeat myself, I have about a thousand times more confidence that Sony and/or Microsoft will keep their PS5 and Xbox operating systems secure and not crapped up with stuff like this, than I do that random TV manufacturers will not result in a cybersecurity or privacy disaster.

Yeah, the PS and Xbox OSes show you ads, and they have telemetry. But both companies also have an extremely important core functional need of keeping them secure, because possible fuckery with the OS could result in game piracy/DRM bypasses and a direct threat to their revenue models.

The gaming consoles aren't subsidized via the data collection like smart TVs are via content recognition (selling everything on your screen to advertisers).

Consoles are sometimes sold at a loss, but the revenue model is different. Playstation plus/game pass, a cut of game sales and microtransactions, exclusives, and accessories.

No one should ever connect their TV to the internet. There just isn't any reason to, get access to your streaming apps another way.

Hope you don't have any open WiFi networks nearby. IMO it's better to put it on one of your networks and isolate it from the internet and other devices.

Yes. I bought a Samsung TV and there isn’t a way to set up Art Mode without the internet. So first you have to get a raspberry pi, install pi hole, then switch your router’s DNS.

What a wild experience 2026 is. But I do feel like a wizard.

walrus01 3 hours ago | parent | next [-]

You don't need an actual physical raspberry pi to temporarily run pihole on your LAN, you can, for instance, install a barebones debian VM inside any common hypervisor on your laptop like virtualbox or qemu, then install pihole on that basic debian x86-64 system.

They might hardcode DNS. It's not certain that this will work.

slau 3 hours ago | parent | next [-]

This is why I’m a bit conflicted about DoH and ODoH. Firefox and Chrome have defaulted to DoH for years if I’m not mistaken (although I’m in Europe so I believe my FF still uses regular DNS instead of DoH by default).

This also means that DoH effectively sends all your queries to CloudFlare on FF. Chrome is slightly smarter and tries to map your DNS provider to a DoH implementation if known.

That's why I'm not a fan of DoH or certificate pinning. Those are tools of control.

tkel 3 hours ago | parent | prev [-]

I have my router set with iptables rules to block/redirect all port 53 and you can also add known DoH to a blocklist to try and force LAN devices to use your router DNS.

lodovic an hour ago | parent [-]

I have a separate lan for untrusted devices, I only use whitelisting. No public DNS for these devices.

Jnr 28 minutes ago | parent | prev | next [-]

I block known DoH servers on my lan and forward all dns requests to my dns server.

CyberDildonics 3 hours ago | parent | prev [-]

You can intercept normal DNS with iptables rules.

The best way to deal with a TV you don't trust is what no one wants to hear.

Open up the back and disconnect the wifi antenna. It is easy to open them up and everything is pretty simple and obvious once you do.

Upvoted. This is precisely the kind of thing I expect to read on HN.

This does not provide any meaningful protection against data exfiltration. The TV is very possibly using public DNS or outright phoning home through stable IPs.

If it connects to another network, it's somebody else's problem. Unless of course, it has a built in webcam or microphone.

stvltvs 3 hours ago | parent [-]

It does, at least for any media played through the device. Read up on automatic content recognition.

I haven't seen any open WiFi networks around me in years. I don't think it's a thing anymore; it's definitely not something a TV company can rely on.

baby_souffle 3 hours ago | parent [-]

They're not unheard of in cities. Hotels and shopping malls have them. Some residential ISPs will also broadcast a public access point using a slice of each customer's bandwidth allocation...

Another reason not to use ISP hardware. That's on top of a well-known backdoor (https://en.wikipedia.org/wiki/TR-069).

dhosek 3 hours ago | parent | prev | next [-]

When I had Comcast internet, I could get on those, but it required a network profile to actually connect to the internet. That said, I wouldn’t put it past TV makers and Comcast to collude on using this to allow backdoor network exfiltration.

They all have captive portal for regulatory reasons though.

Symbiote 11 minutes ago | parent [-]

Depends on the country.

The cafe I live above in Denmark just has an open network.

I have an open guest network with a captive portal, and not once have I seen my LG TV try to connect to it.

Pretty sure they can get internet through the HDMI cord from Roku or similar device

MrDrMcCoy 4 hours ago | parent | next [-]

Source? HDMI includes Ethernet in the spec, but I've never heard of any devices actually implementing it.

RiverCrochet 4 hours ago | parent | prev | next [-]

That would require the Roku to specifically be set up to act as a router. You can't just connect to a random device that's not specifically a router/AP and use its internet connection.

Since Roku like other smart TV companies makes money off of user data captur, it's not incentivized to enable those conditions for a downstream device, especially if not specifically advertised as a feature.

toast0 2 hours ago | parent [-]

If this was a feature they wanted to provide, it would simplest to set the Roku up as a bridge. No dhcp, no nat, just a virtual switch. Roku devices run on Linux, if their HDMI chip supports Ethernet and that's plumbed to a Linux supported MAC (probably not), it might take an hour to build and test the feature. Longer if the wifi interface doesn't like being bridged (I've seen that on some openwrt devices).

There's esp-idf examples from espressif for doing bridging on an esp32 if you have one with a MAC and a PHY and/or spi mac+phy.

Or for wired ethernet, they could include a three port switch IC.

mikestew 3 hours ago | parent | prev | next [-]

This again? Yes, it’s in the spec. No, no one has been shown to have actually implemented it. No streaming box is going to allow random devices to use their connection.

toast0 2 hours ago | parent | prev | next [-]

E-Arc uses the wires intended for Ethernet. Hook your Roku up to an earc port if you're seriously concerned about it.

walrus01 3 hours ago | parent | prev [-]

does a roku provide a dhcp server, issue a dhcp lease, do NAT and routing to things that are plugged into it over the 100M ethernet built into a current gen HDMI link?

This is the best approach
