Priority

I have never really understood priority.

What I really want to do is set the priority of one pc that is connected to my router higher than the rest. I have a switch that will do this, but it doesn't really work for internet access ( which is the one thing I want it to work with). For example, if PC 2 is transferring a large file over the internet, the supposedly high priority PC is still suffering serious lag. My guess is that this is caused simply by the router bottle-necking. I mean I don't really know, but I can't see any other reason.
I can set a bandwidth allowance in the router but this seems silly. Why limit a PC if no other PC is using the internet?
I seem to have some kind of mental block about this, lol. Can anyone explain how I should do this?

What kind of router?

It's an Asus rt-ac88u.
The problem seems to be that data is coming down from the internet, triggered by one or two PC's on the network. This is consuming all of the download bandwidth causing delays for the other PC's. The issue is how to stop that flood of data. I don't really want to bandwidth limit the pcs responsible but I don't see any choice. I monitored the wan port and there is very little upload, just a ton of download. Its nowhere near saturating the router or the lan so neither care, but it is saturating the broadband connection itself. So it seems to me the only way to fix this is to bandwidth limit the offending pc's? I am reluctant to do that because of course it is maybe limiting the other pc's when there is no reason to do so.

What you are looking for is called Quality of Service (QoS) - so if you type ASUS RT-AC88U QOS setup into google you'll find what you're after.

I have always been scared off qos by all the settings. I will give it a try though, with no settings, and see what happens.

If you follow one of the YouTube videos it's pretty straightforward.

Cheers.

Oh, I suddenly realised I am being stupid. The other PC's are using site to site tunneling anyway. It seems that the tunneling priority is low. So QOS seems to be working as I wanted it to, without any configuration at all. Does that sound about right? I have no idea what the priority of tunneling messages is. Anyway, it does seem to work. The two busy PC's, no matter what they do, they are not slowing down my gaming PC. The switch of course takes care of any LAN traffic and all that's working just fine. Thank you for the help! It's all great now.
