Wifi vs hardwired for streaming

To be honest, cat-8 is cat-8 is cat-8. 22 or 26ga. It’s a spec that all cables need to meet. Because of having over 2 dozen competing wireless systems around my house, I rewired my house to 16Gb using Phizli cat-8 cables of varying lengths (2-15m) all home run connected to a Dell 8024F switch using ipolex X001DGYAU7 RJ-45 SFP+s and have no problems streaming anything: audio, video, and video. I also use HP 1820 switches connected via fiber to my remote media closets. 
 

Of course, having a 5GB fios connection helps, too. 

Wifi when setup correctly can be rock solid. For example, turn down your radio transmission power (Tx) so you don’t have your neighbors clogging up your radio channels. Did you ever wonder why you see so many networks with funny names or the default provider ones that many people never change(SSID's) when you go to setup a new device in your place?

Distance will suffer but if in close proximity to your devices, not a problem. I run my Wifi at 50% (or 12 dBm of 24 dBm).

I wrote about this in another thread but the above is a summary and can be researched for more detail online.

@easystreamer Reducing your transmit power so you limit your Wifi to only your home/property is solid security advice, and it makes you a good neighbor.  Unfortunately it doesn't reduce your neighbor's transmit power so AFAIK you will see the same amount of channel congestion.

Implied in your approach is the use of a Wifi analyzer for your laptop or phone, which is also solid advice.  Knowing your signal strength and what channels are free is a great way to maximize your throughput. 

@erik_squires if your power is low so that your neighbors will not see your SSID, then they are not clogging up your radio channels.

If your neighbor has full transmit power such that you see their SSID, you are causing congestion on their network, even if not logged on. That is just how the Wifi protocol works. That is on them :)

When you see all your neighbor SSIDs, that is just a demonstration of how congested the Wifi landscape can be when everyone in your domain is on full throttle with their Tx.

@larseand The T8 has an SFP, use it. A long runs of optical is your best choice.
