TP-LINK_Archer_A9_v6.x

I'm considering the TP-LINK_Archer_A9_v6.x.
It's not listed but everything (including 5Mhz wireless) should work?

I found this page:

It doesn't look like an attractive target. With the exception of the CPU that's marginally faster, it has the same small flash space as the years-old Archer C7 which can be bought used for a small fraction of the price, minus 1 USB port (and in fact several posts on the forum say that the C7 isn't considered a good investment, so I imagine that the same applies to the over-priced A9).

If it's not listed as supported, then it isn't supported at all[0], until someone gets it on their desk and tries working on it.

[0] and there currently isn't a single device with QCN5502 supported by OpenWrt. While it's reasonable to assume that it won't be that much different from its ath79 predecessors, no one knows for sure until someone tries to port it - and it very likely will need some SOC specific changes.

And at around $80 new, I don't see that happening in the new feature (I don't think it's worth even half this price), and by the time it's widely available used for cheap, the 16 MB flash space is already too small.

I thought the warning on the front page was not to but routers with 4mb flash so I thought 16mb should be ok.
Mmm.

The specs of this router (assuming that it gets supported one day) are good (including the flash size), but it's just too expensive for what it can offer (single core mips, 16 MB flash, 128 MB RAM). There are better devices around for just about the same or even slightly less money.

I have Archer C7, which has similar specs (although the processor is a bit slower), and after fresh insustituible of OpenWrt, there is only a few MBs of flash left. So if you happen to want to install something that requires rs python for example or some packages that have many or large dependencies, you could run or of space.

If, however, the specs are good for your requirements, then you could just get a used C7 for $20 or even less, and it's well supported.

Plus C7, for example, has 2 USB ports, which can be a lot more useful than just one.

But then again, as @slh says, there are much better devices in the range of $40 to $80, so if you outline your needs, people may be able to recommend some.

I bought the A9 in sweden last black friday, it was approx 40 usd with shipping.
But there is no custom rom/fw anywhere for it and the last update it got was sometime early 2019.
Is there something a total noob at this could do to port openwrt to it?

I think the hardware is

  • CPU: Qualcomm QCN5502 WiSoC (MIPS 74Kc)
  • WLAN: Qualcomm QCN5502/QCA9984
    802.11n 4T4R:3SS (600Mbps, 2.4GHz)
    802.11ac 4T4R:3SS (1300Mbps, 5GHz)
  • USB: 1x USB 2.0 ports

I was drawn to this router by the same review as OP.

Based on the firmware source on the TP-link support site, it appears that this router's firmware is openwrt.

So I guess the review site wasn't entirely wrong..

Hi Mbowie,

I also get this router based on one of the recommendation sites. But those seem to be completely fake.
Where did you see the information about the firmware being based on Openwrt? That would be very surprising.

Otherwise, does anyone know if someone is working on making openwrt work on this router?

Regards,

Bert

Wow, indeed, TP-link provides the whole openwrt source as in their GPL code package. Version 12.09 if I looked at it correctly.
Wonder if there is something useful to get out of it, or if all the required magic is in a binary blob.

Regards,

Bert

The readme states that on building the code from the zip file, OpenWrt binary images are generated.

Archer A9 is on sale in many countries in the third world, which is why I bought it, and some site recommended it as well for open source firmware. Infact many of my colleagues bought one to replace their wifi4 routers. I assume this is similar to the a7 in terms of source code

I hope a kind hearted dev reads this and tries their best on this.
