What's the first thing you do when you get a new laptop or system?

You know when a $600 Dell gets better wifi performance than a $1700 gaming laptop that something's wrong

My first thing is usually feeling tremendously disappointed about it. Happening right now w/ the MSI Stealth Pro.
It seems to happen with most expensive laptops. They just aren't worth it.better to keep desktops for performance and laptops for mobility.

I did just play a Dota 2 match at 1440p w/ the highest possible settings and was able to multitask across 2 other 27" monitors during respawn lulls without the system slowing down. Though the fans are a'blarin. Not too shabby. Especially since it's over 2 mini display port cables, apparently my monitors support daisy chaining.
The biggest real dealbreaker so far is the keyboard. They completely removed the left Windows key, which is so, so vital for productivity. The keyboard also kind of sucks for typing quickly in general. Overall performance is great though, and I'm sure would be much better once I got a Samsung SSD or 3 into it, if I kept it.

Has anyone ever tried a workflow where you use separate Windows user accounts on the same machine for separate purposes?
I use one for administration and one for normal use. So always two.
Separate for work and play can work, but I think would generally be annoying.

Nuke / Pave to remove vendor crap & update drivers / bios
Definitely, first thing is always a fresh install before even looking at the system.

One of the advantages to enterprise engineering.

Although it does have a cool feature ( which may be available in enterprise too ) where it uses the wifi and lan simultaneously and does QoS to put the more important apps onto the lan. I had to enable it ( was after that post ).

I'm pretty sure the Intel Pro Drivers support this kind of stuff, though rarely would it be useful.

That's confusing terminology. When is a WiFi not a LAN?
That's sort of a cool feature, but when do you have your Ethernet saturated to a point where it would be beneficial?

Testing probably should be done in a VM to protect your machine in general, but two accounts, admin and standard for sure.

Yeah, LAN is what their interface calls it, I should've corrected it lol. Guessing "gamers" ( I'm not one so I can't speak to it ) call it the LAN because of "LAN parties" where everyone would wire up a long time ago. IDK.
I don't know about saturated, but I've noticed that when I'm downloading a file and do a speedtest.net test, my numbers are very tangibly degraded. So even if that's not supposed to happen, it's an observable phenomenon and makes me wonder if adding in a second connector simultaenously wouldn't protect against that somewhat. When I was putting this laptop through it's paces I was playing a 1440p game of Dota 2 on its highest settings and multi-tasking across 2 other monitors downloading apps, installing software, and doing general web browsing, I don't know how much of an advantage their was to using both wifi and lan, but it all felt surprisingly instant.

No, actually it would make it worse by adding unnecessary latency and a separation / recombination process onto the network. Minor, but definitely no way to improve but there is opportunity to degrade. The speed you are talking about with Speedtest.net is WAN speed, having lots of separate paths on the LAN won't affect that.

Just to be clear, it doesn't route the same traffic over both adapters, it divides the full workload by application / purpose and routes things discerningly.

Understood, it is a lot like NIC Teaming. Still requires an extra layer of overhead that, unless you are getting some benefit, is a negative. Since the WiFi connection will have extra latency of its own and more signal problems (if it doesn't you have other isues) and since you presumably are not saturating the main connection, it seems to be two negatives without a positive. The positive is only a theoretical one in a case where you are surpassing 1GigE of traffic. If you are actually doing that much, you need to upgrade your networking and this is, at best, a really poor bandaid.

Wouldn't it theoretically at a minimum reduce contention for latency on the adapter that it dedicates important traffic to? Which I think for gaming is the point. So if my Dota 2 match is the only thing running over the ethernet for example, it'll never have to execute the evaluation of whether to commandeer the adapter for each new packet from something else it might be doing, like downloading a file or serving a web page? In other words if the important stuff is in its own lane, wouldn't that exempt it from any kind of work to prioritize or rearrange traffic like it'd hit if it were sharing a connection?

How would it do that? The data is coming off of the same switch on the other end. Ethernet has not had contention since the introduction of switches.
Wifi, on the other hand, always has contention. So contention is what you are introducing where none existed.

Nope, doesn't change anything. The computer doesn't know that the traffic is prioritized. Basically you are attempting to do QoS without really doing it. The NIC is going to treat the traffic with the same overhead whether DOTA is the only thing talking on that channel or if other things are. The NIC is able to handle wire speed without additional latency, lowering the work it does does not free things up for other traffic realistically, but it does make everything else slower by sending it on the Wifi.

Maybe you can correct the issues w/ how I'm thinking about this:
- Information ( in the form of requests and responses in both directions ) needs transfer between the laptop and the router.
- Information is not transferred in its raw or natural form, it requires preparation, translation, and fragmenting into smaller chunks and reassembly from smaller chunks for incoming information.
- The laptop sends its various requests or responses to the router through an adapter, which intelligently handles the above tasks.
- Therefore, handling 4 separate applications' worth of information coordination is an amount of work, which consists of each application's information coordination workload. At any given moment, there may be requests currently being coordinated on adapter 1 w/ the router, and new requests coming into it.
- By removing say, one of the applications from this channel ( adapter 1 ) and moving it to its own channel ( adapter 2 ), it guarantees that at any given moment the new network adapter isn't spending its clock cycles handling other requests, receiving new ones from other applications, or having to mix in requests from the removed application into the packet batches.
- This has an effect similar to splitting a specific task off onto a dedicated second core in CPU processing, although the primary core has more than enough horsepower and capacity to handle all of the work of the computer, by isolating a task onto a separate core, the task switching penalties and "contention" for focus are removed, and the 2nd core will respond, even if only marginally or trivially, more quickly to any incoming tasks dedicated to it because its resources are guaranteed to not be doing anything else, even if we say that none of the other work at play will or should matter because the hardware can more than easily enough handle all of it.
I may totally misunderstand how packets and routers work and be missing how things you've already mention invalidate the summary above. If so I apologize and am definitely thinking about this from a programmer's perspective. But, I'm genuinely interested in understanding these networking concepts so your help is very much appreciated! I find this stuff ( networking, servers, general IT ) fascinating despite my limited exposure to and knowledge of it.

Maybe this part is the key. Are you saying that whatever handles the processing in the adapter is so fast that it's basically 0 ms? So that the embedded processor in the NIC, even when handling 5 separate applications' worth of information workload, say a large file transfer, a bunch of web pages, IMs, websocket data, etc, will always be 0 ms and that there's no subprocessing at all?
In my mind latency is a byproduct of a few different components, the network beyond the laptop, but internally on the laptop, the time it takes for the CPU to hand a request off to the NIC, and then the NIC to translate that request into appropriate formats and packets, and then the time for the NIC to intermingle that w/ the streaming it's already doing to the router. So by reducing the work in any one of those steps you're getting closer, even if only theoretically, to 0 ms.

I'll toss a small part into this mostly to see if Scott agrees more than anything...
Assuming the WAP is connected to the same switch that your PC is connected to, and that the router is also connected to that switch, you'll gain little to nothing because the switch will be mixing those packets together before sending them to the router assuming they are all on the same VLAN/router interface.
Also the use of the DOTA software is 'just one more thing' in the line up that that has to be processed before either NIC can do their job. In a situation where the gains by splitting traffic are trivial at best and non existent at worst, this additional layer does nothing but hurt performance, it could never help it.
Scott also mentioned that the WiFi connection will suffer the additional inefficiencies inherent of WiFi - latency and a contention based network. Now, if the LAN port is saturated, and you'd see actual gain from splitting of traffic over two network connections, then you can overcome these inefficiencies, but that doesn't seem to be the case.
