Add support for TP-LINK AX23 V1

I have a brand new TP-Link AX23 Gigabit dual-band WiFi 6 router.
Some main features:

  • 802.11 b, g, n, ax.
  • 802.11 a, n, ac, ax.
  • Dual-core CPU.
  • 16 MiB flash (based on the size of OEM firmware)
  • four external antennas (2×5 Ghz and 2× 2.4 GHz)
  • Gigabit WAN (1×), and LAN (4x) ports.

US and EU versions, I have 1.00 EU. There is also a 1.20 version, but tha same FW.

Sadly, I do not have serial equipment for more info on hardware, or debugging. :frowning: What i can help with is testing if we have a working snapshot.

What is the possibility of getting this supported?

You might have gotten lucky, this looks like a supportable platform from what I can find:
MediaTek MT7621DAN + MT7905DAN + MT7975DN (2x 2x2).

Without serial or some other way to find out the exact internals, flash layout etc. you won't see support though.

your findings seem correct -

serial console's in the middle, between the two shielded chips.


You are so fast ! I'm examining the same document for the same info. :slight_smile:

DISTRIB_DESCRIPTION="OpenWrt Attitude Adjustment 12.09-rc1"

What should i look for more info in the FW file?

on 4pda you will find that MR70X is able to run firmware from AX23 so they should be similar. And the pull for MR70X (MR1800X) is here . At least flash layout should be the same . You might start there.


Just to be clear. I am NOT a developer, so I can not port openWRT to this device. I am just a user who has one, and can help with testing. So don't wait for me with development! :slight_smile:

Ah, so seems AX23 is "Next-Gen Platform – The Next-Gen High-Efficiency Qualcomm Chipset provides fast and stable Wi-Fi while saving more power consumption." as advertised, so there's the possibility of having sooner or later built for this TP-Link AX1800 AX23 thingie?

(as opposed to the dead end of Broadcom BCM6755 in AX20)

This thread clearly states its a Mediatek chipset, where did Qualcomm come from?

from their tp-link official intro

Archer AX23 Key Features:
Next-Gen Platform – The Next-Gen High-Efficiency Qualcomm Chipset provides fast and stable Wi-Fi while saving more power consumption.△

as in:

yet then, after press-release over the internet, they suppressed the word about Qualcomm and just "chipset" everywhere:

Then there might be a v2, or it's just clue less marketing, wouldn't be the 1st time.

If you want to be sure, open your unit.

clue less marketing

probably this is it.

Then, it's not Qualcomm but Mediatek, because seeing chip is more proof than telling in an advertisement post even by company :man_shrugging:

As far as I know, there is only V1.00 and V1.20, but no V2. No indication of other HW versions on TP-Link website. Topic title updated for V1.

come on, look here! some detail about AX23

thank for reposting what was posted mid '22 already.

How does that change what I wrote? FCC pictures are no straight path to support. If only it was that easy.

Like I said above MR70X can be base to support AX23 . PR #12104 add support for Mercusys MR70X)
here are tplink safeloader ID's i found in ax23 OEM firmware

"{product_name:Archer AX23,product_ver:1.20,special_id:45550000}\n"
"{product_name:Archer AX1800,product_ver:1.20,special_id:45550000}\n"
"{product_name:Archer AX23,product_ver:1.0,special_id:4A500000}\n"
"{product_name:Archer AX23,product_ver:1.20,special_id:4A500000}\n"
"{product_name:Archer AX23,product_ver:1.0,special_id:4B520000}\n"
"{product_name:Archer AX23,product_ver:1.20,special_id:4B520000}\n"
"{product_name:Archer AX23,product_ver:1.0,special_id:52550000}\n"
"{product_name:Archer AX1800,product_ver:1.20,special_id:52550000}\n"
"{product_name:Archer AX23,product_ver:1.20,special_id:52550000}\n"

why would you add the safeloader request to the MR70X PR ?
that's not even close to being on topic ...

Since support has been added for the v1 - do we have any info on the differences to the v1.20 and whether those would prevent usage as of now/warrant adding of support seperately?

in the case of tp-link, minor rev changes usually still use the same hw, and fw.
