NWA50AX / NWA210AX - questions
Dear Zyxel support,
I am a "curious" owner of both the APs in the topic title and I have some questions/things that are not clear.
Not sure how to start this, but here I go:
I did some test on both of these access points and I am finding some differences between the power levels at different settings.
All tests were done at 80Mhz, AX, Europe(country code: RO), base channels: 36, 52, 100.
NWA50AX – AX: max EIRP as per certification: 199.07 mW / 22.99 dBm(EU 5150-5350); 997.70 mW / 29.98 dBm(Max EIRP-5Ghz-EU 5740-5725); actual transmit power: 23 dBm / 23 dBm / 26 dBm - this looks ok.
NWA210AX – AX: max EIRP as per certification: 183.23 mW /22.629 dBm (Max EIRP-5Ghz-EU 5150-5350); 899.20 mW / 29.53 dBm (Max EIRP-5Ghz-EU 5740-5725); actual transmit power: 16 dBm / 16 dBm / 22 dBm. - this looks not ok.
So, I will try to ask my questions per device and as a general Zyxel device approach.
- Q01: I have 2 devices that are making a "hissing" noise when high speed transfers are taking place(cheap capacitors?); is this ok or not?
- Q02: Mesh feature: If I connect 2 APs(NWA50AX) to a switch and enable k/r/v, will the handover be done in a real mesh approach(seamless) or this "mesh" thing works only over wireless(WDS)?
- Q02-1: regarding the "mesh" question above, can I mix some NWA50AX with some NWA210AX and get the same functionality?
- Q03: what is the maximum speed I can obtain from this access point using an AX201 client/Win11; I was able to get ~60MB/s, which seems low, but fair; I would like to know the maximum speed in real life conditions. I am sure tests were done internally for this.
- Q05: it seems that the AP is allowed and able to transmit/emit higher that it actually does(at least compared with NWA50AX; is this a firmware issue or something else? Personally, if allowed, I want to be able to control the upper/lower limits as per EU regulations(please see the attached pictures). So, I want maximum power that the AP can provide in the EU, without artificial limitations(I guess 22dBm on on 5Ghz channels if I understand the wiki page right).
- Q06: POE:
I have used the following to power the AP:
https://shopdelta.eu/product_flypage_l2_p17194.html - limited power;
https://mikrotik.com/product/RB960PGS - 48V/2.5A adapter- normal power(if I recall right);
If I enable "Force override the power mode to full power" the AP works ok, so I am not sure if this is a firmware problem, or a POE adapter problem. The same POE adapters work ok on the NWA50AX.
-Q07: does the number of antennas influence the allowed power emission limit? In the sense that if I have more chains, then the power goes lower? NWA210AX has 2, NWA210AX has 4...so...the power limit is lower in the case of the NWA210AX?
-Q08: speed: - I did some tests with an AX201 Intel card(Dell laptop, Win 11), and I was able to get ~113 MB/s; is there a limit on the AP/uplink port? The uplink negotiated at 1000Mb/s; I would like to know the maximum speed in real life conditions. I am sure tests were done internally for this. I also know that there was a "bug" that limited the speed to ~1Gbit/ client. Was that fixed?
Common questions/comments (for both NWA50AX/NWA210AX):
- the default admin account cannot be disabled; this is..not recommended;
- the light on the NWA210AX is...well...big; you should have kept the size of the NWA50AX(personal opinion); It would be nice to be able to actually schedule the LED suppression;
- I do not need 8/16/whatever SSID profiles/ I need one profile for 2.4Ghz and 1 profile for 5Ghz; can I delete the rest? I mean...why should I have things that I am not using anyway? If I want new ones, fines, I can create;
- How can I change the country after the initial configuration?; I've managed to block my radios on the NWA210AX because the main SSID profile country was not matching the rest?(the main was CN, the rest were RO); this was doing some tests regarding emmision power;
- FTP/HTTP/telnet should be by default disabled on initial(out-of-the-box) start; if I want to enable then, fine, if not, they should be off;
- I really don't like that emails/SSID passwords are "plain text" in the diagnostic logs; it is not your problem what my passwords are; these should be "one-way" encrypted; I know there were discussions regarding this aspect, but still, those should be encrypted by default;
- I need to be able to set my uplink/other port speed manually; I know the standard says auto/auto, but most of the APs allow you to set 1000Mbit/full duplex or similar;
- It would have been wonderfull if the mounting plates were the same size, in the sense that I can just remove a NWA50AX and slip in a NWA210AX; cheaper for you and less stress/work for me on the long run(I assume it is simpler to just order 20 000 plates the same size, instead of 10 000 and 10 000;
For the positive things:
- power supply in the package;
- physical size;
- mounting plate(plastic, but I hope it will last for a lot of time; it seems fairly solid at least for now;
- screws in the package: well done;
- neutral package: well done; anyway it goes to the trash;
All the tests were done using the latest firmware for both APs:
I am not considering myself a wireless networking expert, but the above did "ring some bells". Please see the attached pictures, especially the excel screenshot and please consider the above as "positive suggestions".
My apologies if this message was too "rough". I have attached some relevant pictures. I can also provide some diagnostic logs that were taken shortly after the tests.
Thank you kindly for your time and support.
