HAP AX2 wifi speed too slow!

Hi, I’m AndyV.

I recently purchased a HAP AX2 (update to 7.14.3 + qcom done) to combine with my home modem to create a personal LAN / WAN.

I tried both with a “quick set” configuration and with a hand-made configuration, but I encounter the following problem: some devices are unable to reach the speed that they can achieve if connected to the home modem.
The speed between modem and AX2 via ethernet is 1Gbps (as it should be).

The home modem is a “Vodafone WIFI 6 Station” equipped with a 6E wifi card.
The specifications of the HAP AX2 are known.

I tested the following devices and got the following results (download/upload):

iPhone15 → Modem = about 700/550 Mbps
iPhone15 → AX2 = about 200/400 Mbps

iPhone15pro → Modem = about 700/550 Mbps
iPhone15pro → AX2 = about 700/550 Mbps

pc with RTL8852AE → Modem = about 700/550 Mbps
pc with RTL8852AE → AX2 = about 300/400 Mbps

pc with Intel AX200 → Modem = about 700/550 Mbps
pc with Intel AX200 → AX2 = about 300/400 Mbps

iPad5gen → Modem = about 550/400 Mbps
iPad5gen → AX2 = about 150/300 Mbps

I attach the hand-made configuration currently loaded on the AX2.

Can anyone explain why some devices manage to reach the correct speed, while others fail?
I have also done tests with other devices (not written above) that manage to reach the correct speed.
I don’t think it’s something related to the devices’ wifi cards, because connected to the modem they can perform correctly, while connected to the AX2 they don’t.
I’ve tried to provide as much data as I can.

Any help will be considered invaluable, I’m literally going crazy…

Thank you all!

The only way you can known for sure is of you do those tests with modem, then disable its wifi and reconduct those tests with AX2 using the EXACT same wifi settings (frequency, width, security, … everything the same).

The fact your iPhone15 pro does get full speed, indicates nothing is wrong with AX2.

Hi, thanks for the quick response.
How do I know what exact frequency my modem is using?
During the tests I checked that I was using the “5GHz network” both on the modem and on the AX2, but I didn’t know how to find the exact frequency.
Thanks so much, AndyV

I guess if you log in into that modem, you should be able to find it somewhere ?

On PC (e.g. Wifi Analyzer) and Android (same name Wifi Analyzer) I know the tools to retrieve that info, not on Apple-stuff.

Try this as well it will show frequency and powers etc on the AX2
