What's faster Lan or wifi N 5GHz?

Such a simple question is more to make sure: what will I have a higher transfer speed from the router to the TV, whether via a regular LAN cable or via wifi in the N 5GHz standard? The TV supports N, and the router N, and also AC. Stability, of course, I know that it will be better on the cable, but I'm not fully informed about the differences in speeds and Google confused me a bit.

The speed achieved by WiFi depends on many factors. LAN will usually be a better choice, especially if your TV and router support Gigabit Ethernet (1000Mbps ports).

There are different radios having different capabilities in the AC standard, so it is not known what even the maximum possible theoretical speed of the resulting connection is. Even if it were known, it is impossible to estimate what the losses will be due to the distance between devices and radio interference. There is no answer to the question of the speed you will get between the TV and the router.

Take into account that what is written on the card or the manual must be divided by two - the transmission speed, which is often not achieved anyway when there are disturbances or the signal level is not satisfactory (two-way communication).

And what is more certain: 300 Mb via wifi or 100 Mb via cable?

300Mb via wifi will not be achieved, on good equipment 100-150Mb. Better cable, it is "only" 100Mb, but sure.

Stowing with a cable will always be much more sure. Anyway, your TV would probably rarely, if ever, need higher speeds anyway.

100Mbps is not the capacity of the entire network. This is the speed of the connection between the device and the switch. A switch is usually not limited to a total of 100Mbps, even if it's a hundred. In general, data on the capabilities of a given switch should be available from its specifications.

ok, maybe I will formulate the question differently : to watch Netlix in 4k, better if I connect the TV via a cable to the router or a can via wifi in 5GHz in the N standard because I can't in AC (the router is half a meter from the TV); Oh, and are there lan cables with greater bandwidth or would I have to have a different plug in the TV and router for such a faster cable?

The speed of the 5GHz and 2.4GHz network has virtually no difference, even 2.4 I think it is faster, the 5GHz network is simply more stable, but for image transmission in 99% of cases the cable is always better ... The cable is best lan cat6 . In the router, it is also worth checking if and how which port is 1Gbit and connecting through this port.

and you do not know if there is a 1Gbit port in this newest white UPC router

What router is it?
Since the TV is half a meter from the router, do not even think about it, just connect it with a cable. Cable connections will not be replaced by any WiFi routers, even if they are gold.

And you want WiFi?

Only right answer.

So what if WiFi describes "more" how it will actually be divided into other devices, because probably some phone, laptop or other device will be used.

Every UPC modemorouter currently has 1 Gb LAN ports.

and does my TV support 1Gbit if the specification says Ethernet: RJ45, IEEE802.3 10BASE-T / 100BASE-TX? Because if I can see it correctly, it would only support 10 and 100, so is there any point in buying cat6 anyway?

No, only 100Mbps.

So it basically makes no sense for me to buy a cat.6 cable if the tv only supports 100Mb / s? (damn model Panasonic from 2017 with built-in Netflix and no 1Gbit wrrr).

But why do you need gigabit if Netflix to UHD (4k) requires 25Mbps?

Connect it with the most ordinary 5e or 6 meter patch-cord and it should work - there is no need to look for problems by force.

NetFlix on the TV will go well both on WiFi and on cable.
It's a fact that 4K TV content requires a lot of transfer, but is resistant to "slugging". I recently watched a movie on NetFlix and accidentally restarted my router. The TV (Samsung JU6510) continued to play the program for 25 seconds until the buffer was exhausted.

It can and is resistant. Ake, if the router is half a meter from the TV, why limit the ratio of a small and limited WiFi bandwidth if you can let the cable go?
You will watch 4K via WiFi, other devices working on WiFi will have worse access to the medium. In my opinion, only a cable.

I am not looking for problems by force, but for the optimal solution ; By the way, I don't see much difference whether I connect via cable or via wifi. Take into account that the router is very close to the tv, so at 5 Ghz GHz nothing from the neighbors to go disturbs interferes because everyone has 2.4 and it is very close, so it reaches the max signal in wifi, and theoretically I can get a slightly higher speed on N than on the cable and additionally get rid of the cable. Mi Netflix, after all, whether it is on this or that, it will sometimes hang slightly and on this and that on TV shows me a maximum speed of 15Mb / s; in addition, to jump to 1080 or 4k it takes about 1 minute or more, and sometimes almost immediately. And the internet with UPC is 120th.

On the operator's equipment for $ 20 - this is also worth recalling.

I will also remind my colleague that this Compal (ConnectBox) has big problems at UPC (and not only at UPC Polska) - please enter the phrase "PUMA6 test" in Google and read a bit about it.
And here is something from our backyard:

And if you cut the link bandwidth to 25Mbps, you won't see it either, so the optimal solution is either, since both work the same. If something is clipping and freezing, it does not have to be the fault of the router TV connection.

As your colleagues wrote above:
The cable is always a more stable solution and eliminates 90% of future problems. You are 50 cm, so it's easy. The bandwidth of the transmission channel is only one of the link parameters - usually not even the most important.
Anyway, you connect the TV via WiFi, you will cut the radio band that you can use for other mobile devices (retransmissions, variable delays for WhatsApp, damaged frames, etc.). You will gain nothing on TV and you can lose in another place.

In general, my question came from the fact that I had problems with Netflix, i.e. buffering a movie or series that was being started up to 25% and nothing. I thought that it may be a problem with the speed and stability of the connection, etc. or, as above, my colleague indicated a defect of the UPC router. But interestingly, none of these things. It turns out that on the UPC community forum and in accordance with UPC's recommendations, the remedy for this is to simply disable IPv6 on the router (in DHCP settings), and leave only IPv4 (by phone via a consultant or via chat). Well, it helped, everything is running smoothly now. It is said that it also helps with VPN problems, network games etc. I hope this post will help other users with a similar problem.

However, this does not change the fact that this equipment is very problematic and its disadvantages have not been eliminated to this day (and in my opinion they will not be, because it is a disadvantage of the chipset itself).
And new info - the need to restart Compal (and sometimes even reset with a button) which has been working non-stop for over 2 months.

you are right, it does not change the fact of its defectiveness and trashiness; when it comes to resetting, I do not have such a need, maybe because I always turn it off at night (because why should it pull electricity, disrupt other bands, emit waves that are probably harmful to humans overnight).

I do that too
As for the connection, all you need to do is connect the Connect Box to the TV with the cable attached to the Connect Box, or with another CAT5E cable.
There is no need to combine with WiFi because the cable will always have a more stable connection.

Compal is quite ok here - if you do not use it, it reduces power consumption to a minimum (turns off LAN ports, wifi and other services).
Its power consumption with full load is about 13W / h, on average about 10W / h, in "standby" it is about 3W / h.

To sum up, a cable always better than Wifi; Compal with UPC is said to have manufacturing defects; Netflix in UPC works better sometimes when it turns off on their IPv6 router. I close the topic.
