Question corrupta filés in wi-fi download

[nnaear]

I only use Wi-Fi on my PC. Are downloads via Wi-Fi more likely to get corrupted? Does any download manager protect files from corruption during download?

No. Even if your WiFi connection drops, the download should continue (or restart) when connection is established.

Nope, and that's the beauty of the underlining TCP protocol that 99% of Internet downloads take place on. TCP is able to detect data packet corruption and loss at the client and thus is able to request the sending server to resend data if the need arises.

It's almost like the founding fathers of the Internet knew what hell they were doing when they designed the protocols that are still in use today. TCP can reliably send data across any medium be it WiFi, Ethernet, DOCSIS cable, DSL, fiber, cellular, and even satellite.

Device manufacturers do not recommend updating firmware via wifi. Is this related to data corruption due to wifi downloads?

Moreso it's related to connection failures causing the firmware update process to give the user an error. Manufacturers don't want users to see error messages so they recommend using ethernet as it is usually the more stable connection

Even if a firmware upgrade tool downloaded a corrupted/partial firmware file they usually have additional verification in place to ensure they don't flash anything broken onto your hardware.

The main concerns with WiFi compared to ethernet are connection consistency and speed, not data corruption. Ethernet is usually faster and more consistent since there's much less that can interfere with it.

In summation: WiFi is perfectly safe to use.

I don't have a house and I rent. If I move to another house, I'll need to drill holes in the wall for RJ45 cables. I've accumulated many meters of RJ45 cable. I decided to migrate to Wi-Fi. The installation is cleaner, fewer cables, but slower compared to cable.

What minimum speed (Mbps) do you consider good for general downloads and torrents?

My biggest concern was data corruption during the transfer. Fiber optic Wi-Fi download/modem/TPLink AX3000 Wi-Fi router/Dualband Wi-Fi5 1200Mbps RTL8811 USB 3.0 adapter with 4 antennas, AliExpress/PC.

What minimum speed (Mbps) do you consider good for general downloads and torrents?

That is REALLY hard to say without information on your WAN connection, your distance from the router, what is between you and your router, where you are downloading/torrenting from etc etc. A good rule of thumb is that you should be close to saturating your total download speed, eg: if your WAN (internet) connection is 100mbps download you should be getting 70-90mbps over WiFi. But again there's SO many things that can change that, most of which might be out of your control (eg: what if the server you're downloading from is slow? What if your ISP is having congestion that day?).

I think you may be overthinking this a touch? Data corruption over WiFi really isn't that common at all and I say this as someone with a very crappy WiFi setup at home. At worst you might have a non-torrent download fail and you'll just have to resume it or restart it. For torrents if it fails to download a chunk it'll just try again or pick a different source and at the end of the torrent download the file is hashed to make sure it is complete anyway so even if you do get corrupted data, it'll get repaired.

Modern internet/network software is pretty good at preventing corruption, so I really wouldn't worry too much. Like I said, the main thing you'll deal with over WiFi is less speed and consistency compared to ethernet. But if you can't run ethernet cable (same as me by the way!) WiFi will work just fine

Is there COAX wiring? There's a solution using that. If not that, there's always the use of the power wires and if you're going from one room to another and can guarantee they're all on the same circuit, it will definitely work.

Ummm, no. RJ45 is the nomenclature for the connectors used on Ethernet cable. The cable itself will be designated by a CAT number, typically CAT-5e, CAT-6, or more recently, CAT-7. These days, you don't want anything less than CAT-5e if already installed. If installing new, go for CAT-7.

Note there is CAT-8 but they are for data centers. CAT-8 supports a higher bandwidth but is limited to a maximum of 30 meters in length.

Files can get corrupted, and some servers dont allow to "continue" if the dl stops, but thats related to internet connection itself, not if you use wifi or ethernet.

just get a powerline adapter, you can add more, in case you want tv/console have a wired connection as well.

Unfortunately, packet loss is more common on Wi-Fi.

Loss is one thing, corruption another.
