Hi,
it is advertised that the hAPax2 has 1GB RAM and 128MB storage size.
But some online shops say it has only 128MB RAM. This is confusing.
Are there really such different models of this hAPax2, or is rather the info at some shops/distributors simply incorrect?
Here's an example of an online shop (in German, see the row "Arbeitsspeicher (RAM) : 128 MB"):
Compare the above data to the info here at MikroTik:
https://mikrotik.com/product/hap_ax2

Online shops have wrong information. There is only one version with Storage 128MB and 1GB RAM.

Or difference between storage size vs ram got lost in translation ...

Always revert to original product pages in case of doubt.

Maybe an official answer by MikroTik would be good,
b/c I remember to have read some old postings here where similar happened in reality with some old/other models.
I rather would not like to experience such a nightmare situation...

If I recall, AC2 or cap AC had such an occurrence (128 vs 256 Mb RAM), no ?

Yes, I think this really happened
My ac2 has only 128 MB RAM.

A new problem: it seems ax2 does not have any USB port! Really? No mention of USB in the product specifications.
The older ac2 has USB.
I just wanted to "upgrade" my ac2 to this ax2.

Correct, no USB on AX2.
If you want USB and AX, then it's AX3. You'll also get the 'big ears' then.
In all honestly, design favor aside, AX3 is better then AX2.

I think in that case the website always said 128 MB RAM but some users found that they bought a device that in reality had 256 MB RAM, then they bought more and it had 128 MB RAM indeed, and then they started complaining loudly.
But as it says "128 MB RAM" on the website, there is little to complain about.

For the AX2, the website says 1GB RAM so when it comes with 128 MB RAM you can complain.

Too bad. I don't like the ax3, my ac2 is ideal for my needs, some more RAM and flash memory, as in ax2, would be perfect.
Then it seems for me "ac2 forever..."

AX3 is a really nice router with ears/antennas helping it to hear/listen it's client devices better, so better rates should be expected. Being wifiwave2-only device, it had serious issues with wifi couple of months ago, but they all are settled now and everything runs really stable.

I'm in the same boat. Now the issue with "ac2 forever" plan is it's 16MB flash, and newest V7's barely fit.

We use the ac2 with external LTE modems in tight spaces. So the ax3 is hardly a substitute since between the wider base & the "rabbit ears" it takes a lot of space. And even if one is willing to give up some performance/memory, and use the hAPaxLite... it also lacks "real" USB so also of no help. And the ac2's limited flash memory make it hard to be used for ROSE/containers/disks even though it has real USB.

(I don't know if it's appropriate to open an appropriate discussion to discuss this)

but I also agree with the users who were disappointed by the lack of USB on the AX2.
I love my current AC2 and have purchased about a dozen from family and friends as it is really small but very powerful.
I reported to Mikrotik before the final AX2 came out the possibility of adding USB and 2 nice front LEDs for the WLAN1 and WLAN2 interfaces but... all to no avail.

The small size of AX2 - AC2 is perfect and I hope that Mikrotik does not abandon this form factor by continuing to produce this line. I never considered AC3 - AX3 because I wouldn't know where to place it given the enormous size... I only have one case of an AX3 LTE but I was forced because there was no alternative before AX LITE LTE..

Please listen to this Mikrotik ! @normis

I think the availability of interfaces on the different MikroTik models mainly depends on the chips they use in them.
For each new model a chip (SoC) is selected and it offers some different types of interfaces. Adding a new interface type that is not directly supported by the SoC would mean extra support chips and thus increased cost.
So what you see is each model has some specific interfaces like USB, serial port, SD card, etc and it appears random what is available.
(more expensive models not necessarily having more interfaces either)

The only thing we can notice is that the situation is going downhill. 10 years ago MikroTik routers had a touch LCD screen, USB, serial port, LEDs, SD card slot etc and all of that has gone the way of the dodo.
Probably they have done customer satisfaction reviews and noticed that nobody wanted these things anymore.

Some of enumerated features were gone with some reasons. E.g. displays were soem times placed on top of unit ... which can be rack-mountable. In that case it was obscured by equipment, mounted above such unit ... and thus useless. In addition, display activity (refreshes) was frequently causing real performance problems on those devices.

But yes, some features are price driven ... I'm pretty sure most of use came to Mikrotik habitat (also ... or mostly) due to very good price/performance ratio. If we want to keep the ratio down, then we'll have to let go of some features which don't seem to cost much (e.g. including an USB port) but, as @pe1chl noted, rely on pricier support components.

In all honestly, design favor aside, AX3 is better then AX2.

On the specifics of ax2 and USB, Mikrotik has says that heat is the issue. Apparently those AX chips are really hot.

In terms of price/preformance, I would have preferred an "ac2++" with more flash... they could have skipped the potentially more costly AX chip IMO.

The rackmounted versions had the displays on the front. Sure, when you bought an RB2011 for desktop use it had the display on the top and that was inconvenient when you wanted to put it on a shelf in a rack, but the rackmounted RB2011 had no such issue. Same for the CCR devices from that time. Of course it was a problem when the desire to make half-height devices like the RB5009 arose.

What we see now is that several products in the line initially seem nice, until you notice (before or after buying) that they have a critical flaw. They are missing essential features.
That can be the extremely small flash size, it can be the lack of a USB port or other flash storage expansion capability, etc.

For example, I currently use the RB4011 which at the time I bought it was the "flagship home router". But it comes with only 512MB flash and no possibility to expand it (no USB port), and has 1GB of RAM mostly sitting useless.
At work I bought a CCR2004-16G-2S+ which even has 4GB of RAM but only 128MB Flash. In the brochure that was on the website at the time I compared it to other models, and also in the block diagram, it specified that it has a USB port. But it doesn't.
So both these models, which could conveniently run containers, in reality are not very suitable for that.

I think it's not fair, b/c a smiliar device (the "hEX") but w/o WiFi has 256MB RAM, that's the double of what hAPac2 has; that's unfair IMO as the hAPac2 deserves at least 256MB since it has more functionality (dual WiFi) than the hEX:

https://mikrotik.com/product/hap_ac2

Both have 5x Gigabit ports.

It doesn't really matter. To continue to work in the wifiwave2 era, the hAP ac2 would need to have more flash as well.
