Determining slow network with Steam Link?

[4RmHalls]

The title spells it for for you in the form of a question. I have noticed that spikes in activity occur that which hinder gameplay via stuttering audio and visual. And at the same time yellow text appears that says "Slow Network" (this only happens for a few seconds and then it's gone) so it seems to be acute. This is all seen by turning on the option for "Display Performance Information"

How do you connect? If WLAN, then be glad the network is slow only occasionally and not all the time.

Yes sir, WLAN. could it possibly be something with Windows sending pings or anything of the sort?

[ReBoot]

No, it could be something with WLAN being unreliable by definition. Afterall, every single WLAN in vicinity can and in fact does interfere with your transfers. In theory, that's not an issue. The WLAN protocol is designed to handle such cases. In practice though, you'll get microlags. For stuff like file transfer or heck, online play, it doesn't matter. For something as sensitive as real-time game streaming, that's a huge issue. If you can't shield your place from all outside radio transfers (which I suppose you can't as hanging wallpapers containing metal in all of the flat is pretty ridiculous), you have several other alternatives.

First and foremost, make sure that the PC is connected to the router via Ethernet. If you have both the Steam link and the PC connected via WLAN, it's gonna suck big time as you now have two opportunities for the transmission to get interferred with.

Second, try another WLAN band. The Steam link supports the 5 GHz band which is dampened way harder, than the standard 2,4 GHz band. That dampens the interference from outside WLANs.

If that doesn't help, the ultimate solution is to switch to a medium reliable by definition, that's cable. Ethernet is of course the ultimate solution. If you can't or don't want to install Ethernet cables, PLC can work.

Still, you need to understand that WLAN is unreliable simply by the way it works. The (imaginary) aether is a shared medium. That means that if ANYONE in your vicinity is using their WLAN, it'll ♥♥♥♥ up your game streaming. The only way around that is either dampening all external signals or swich to cable.

I can imagine all the extra artifacts in a read-out of wifi compared to corded systems. This is unfortunate as I don't really have the option of running cables all throughout the house. The stuttering isn't unbearable, just an annoyance really.

As I said, PLC may be a valid option. Using it myself as I don't feel like having a 12m cable in my hallway.
Is the PC using Ethernet? Maybe you could move it closer to the router and drag a cable then.
