ASUS Teases ZenWiFi PRO Router
ASUS earlier today teased its upcoming premium home networking product, the ZenWiFi PRO router. Designed in a vertical, cuboidal body with an acrylic top that shows off its MU-MIMO antennas, the ZenWiFi PRO is designed to be space-saving on your desk, while not compromising on range or bandwidth. As an ASUS Zen product, it's likely to be high on the aesthetics, with its matte black body that resembles a skyscraper. The "penthouse" (if you can call it that), features the antennas resembling pillars, as well as an RGB-illuminated ASUS logo that probably serves other functions. The teaser already reveals that the router is designed for 6 GHz Wi-Fi 6E. It's also possible that ASUS throws in goodies such as 2.5 GbE wired LAN and WAN ports, USB 3.x type-C and type-A ports to plug in the next crop of 5G dongles, DAS, and much more. It also wouldn't surprise us if ASUS designs mesh repeaters with the same design scheme as optional accessories, or part of whole-home mesh kits.

Honestly, I get it that you think teasing a router is absurd but I really couldn't manage to extract anything apart from that. Sorry, maybe I haz the dumb? :)
5Gbps is way more expensive compared to 2.5Gbps, as it's closer to 10Gbps when it comes to all the "bad" things involved in making a chip.
Intel's list price for a 2.5Gbps Ethernet controller is $2.40 and their chips have a TDP if less than 2W. Intel doesn't have a 5Gbps product, neither does RealTek, which leaves Marvell/Aquantia. They're not cheap, although I don't know what their third gen chips cost, their previous chips were in the $20 range. They also run hot and require passive cooling. Personally I believe 5Gbps will be a short lived niche, as there are no switches, whereas there are several of 2.5Gbps by now. The price difference between 5 and 10Gbps is also too small in most instances that it doesn't make sense investing in 5Gbps, as you need suitable switches/routers etc.
I have two Aquantia 10Gbps cards, one in my NAS and one in my PC. For large file transfers it's unbeatable. Bonding doesn't work between a single client and server and requires a managed switch. You need multiple clients to see any benefit from bonding on the "server" side and bonding on clients is pointless.
@Valantar I'm enthusiastic about routers :(
I understand why most people aren't though, as they barely understand what the box from their ISP does, nor how vital it is. If people did, they'd invest in better gear. If you truly think that's the BOM cost of a modern router, then you're really clueless.
Yes, your could make a MT7620 based router for $15, but it would be 2.4GHz only and have 100Mbps Ethernet.
The AC1750 router I was involved in making some 7-8 years ago had a BOM cost of around $100, although that was a bit special, as it had a 3.5" touch screen, ZigBee and Z-Wave, as well as a discrete USB 3.0 controller that increased the BOM cost. It was also the first consumer router to a heatpipe for cooling and possibly the first router with a mezzanine board.
My point here though is that now, we have routers with much more expensive SoCs, I know QCA charges $30+ for their higher-end router SoCs, more RAM, more flash, a third 5/6GHz radio and so on. Heatpipe cooling is not rare any more and multiple PCBs are also common. This is impossible to make for $35. Just look up the cost of a good power amplifier or LNA and you'll see that alone accounts for a minimum of $10-15 of the BOM cost in a higher-end router.
So that's $40-45 without the Wi-Fi chips, PCB, ports, housing, antennas, switch IC, etc. and doesn't even take packaging, production or certification costs into account. So yeah, you're way way off the target here.
Marketing a router is obvious and simple. Essentially "Hey, look at our cool new router. It's fast and covers your entire home. It's really gamery/Pro/[insert buzzword]." That makes sense when you're selling a borderline indistinguishable commodity infrastructure product. Teasing? No. I'm sure there are some of you out there! I've considered DIYing routers to get something better, but the cost and time investiture is always way beyond what's reasonable. (Not to mention the size, unless you go really expensive). And the few brands that seem to be actually good are either wildly expensive or impossible to get a hold of. Which leaves me (and most people) with a "pick what looks best of all the crap" situation.
It's based on QCA hardware, has third party firmware support thanks to Voxel and the only time I ever touch it, is when there's a firmware update. That last part is what I'm enthusiastic about, as it doesn't give me any hassle, it simply works. This is also why a lot of people forget they even have a router, as the ones that "just works" are often ignored, which means they are also not updated, which leads them to be potential targets for hackers...
This is why I want to see better support overall from all the router makers and there should be regulation that forces them to provide updates for a five year period, as that's an acceptable lifespan of a router. Many router manufacturers (TP-Link, D-Link and even Asus for a lot of models) issue a couple of updates and a year after they launch it, they drop it like a hot potato and makes revision 1.1 and repeat.
It's a really shitty market to be honest and consumers are either using unsecure hardware or are forced to buy new hardware every couple of years in a best case scenario to have a product that's at least somewhat secure.
This is why I only buy routers that are supported by the likes of Voxel and Merlin.
I'm not spreading FUD, as I have actually tested this, several times to see if anything has changed.
First time was well over a decade ago. If you don't have multiple clients, bonding of Ethernet links will not give you more throughput. Sorry, but it's a fact, a single client using the same speed interfaces can not gain additional network performance from the bonded link using industry standards.
There might be some workaround in Linux, but that's not following industry standards for bonding of Ethernet.
I don't know what experience you have but I claim it's highly limited. I'm using various aggregation standards both at home and in various professional VM and networking scenarios. Shocker, they all work as advertised.
Ok, so did you even read what I wrote?
Once again, bonding/LACP based on 802.3ad does not give you any performance improvements for a single client against a server using bonding.
This is per the standard. This is how Ethernet works.
Even if you perchance have bonding on the client, you will see ZERO performance improvements, as the Ethernet network flow can't be split over two bonded connections, following current standards. The client will only use one link in an instance like this.
However, if you have multiple clients, you will see more throughput on the server end, but you might need more than two clients, as the loads are rarely perfectly balanced a bonded connection, so instead of getting 2Gbps throughput, you might get 1.4 or 1.65Gbps or less/more, depending on the exact test, payload and how many clients you're using to test with.
This is partially because there's still a 50% two clients use the same network connection, since bonding is pretty dumb over Ethernet.
If you still don't believe me, please read this thread, as it shows multiple examples how it's not possible for a single client to go faster than its rated Ethernet speed for a single NIC.

As I said, I have tested this several times. The first time with a Thecus NAS over a decade ago, then with a Synology NAS, a managed switch and even bonding on the client as the system I had at the time had two identical Intel NICs and finally when I worked at QNAP where I had a discussion with some of the engineers there as to why it didn't work as one would think it should work.
And the next time you want to belittle people, maybe you should actually test what you have implemented first, to make sure it works the way you think it works.
No insults, just discussion of the topic, please.
Remember... discuss the topic and not the member.
Thank You!
