Compared to the Pi 4, this chip seems to support AES, which I believe its an issue for OpenWRT if is missing.
How can we get support for this chip and this device?
At that price, donating a couple is feasible.
Please use this topic only for recommendations.
For questions like "how do we get this device supported" please open a new topic.
Thanks!

Ive just setup a TP-link Archer A7 to my brother, seems like a cheap AP/router to me. I really liked that I could make a physical antenna port by myself so that he can use his old 2,4 GHz antenna 
Just had to buy an RP-SMA to uFL 20 cm cable and attach it to the "motherboard" and attach it to the case after using a small saw for plastic 
Next time I need a cheap AP/router device I will probably buy a TP-link Archer C7 due to the fact that it is cheaper and it has 2 USB-ports 
please, provide link.
TL-WR740 works on 19.07. See this forum thread (OpenWrt 19.07.1 ath79 tiny LuCI) for an unofficial build for many 4/32 devices. I'm personally using WR841 using this build for a week now.
Thank you for your recommendation. After reading the post related with aht79 tiny, it seems to be a good alternative to re-purpose unused old hardware for range extension (not routing).
If you plan to buy a new device, the wiki documentation discourages to buy 4/32MB devices (as @tmomas had already pointed out).
Someone else is looking for a replacement for those old and trusty tplink tl-wdr4300 tl-wdr3600 and tl-wdr3500 (this last one without gigabit ethernet ports)? For a small router, Netgear WNDR3700v4 (whenever a used unit it might be available) and TP-Link Archer C7 AC1750 seem to be valid alternatives, gigabit ethernet 1xWAN, 4xLAN, and decent amounts of memory for the firmware and RAM.
I've got microuter one. It has 18x firmware version but i dont know how to compile newer one. They don't support it, you have to compile your own software.
PL-WR300-H1 is cheap one.
it sold as bare board.

Seek keyword as 'openwrt flash 8MB ddr2 64MB mt7620N' in aliexpress
I'm running firmware bin [Zbtlink ZBT-WA05] OpenWrt 19.07.3 r11063-85e04e9f46

you can telnet login as :

As power supp. 5V is ok, from USB P.S.
I modified SPIROM to socket but its optional.
But considering the case and power supply, maybe something else is better... 
like [CHANEVE Wireless Repeater] or [CHANEVE 300Mbps Wireless Repeater Router MT7628KN]

Two points:
The MT7628KN System-on-Chip includes 8MB ram. The Mediatek MT7628 spec sheet indicates that a DDR(1) ram chip can optionally be added
https://www.mediatek.com/products/homeNetworking/mt7628k-n-a
Chaneve is a reseller. The CHANEVE 300Mbps Wireless Repeater Router MT7628KN is also sold as a Kuwifi and I believe is manufactured by ZBT. The same case can contain a Realtek based board.
I bought a Mediatek one and it did not contain a separate flash chip. The web interface is impressive from a minimalist standpoint. Only 2 options for wifi encryption - open vs WPA2(personal). It also is very energy efficient. The serial interface had a u-boot loader but did not run Linux.
Neither will ever run OpenWrt. The Mediatek one has 2mb flash/8ram and Realtek one is, well, Realtek.
In the Mediatek family, I use this one:
Works on a HLK-7688A wifi module and comes preloaded with OpenWrt 14.07 but it is easy to install version 19.07
Pro are:
- Ram DDR2 128 MB
- Flash 32 MB
- Cpu frequency 580 MHz
- 5 ethernet ports (wan + 4 lan)
- 2 serial ports
Con:
- wifi only 2,4 GHz
- ethernet only 10/100 Mbps
- no usb port
Very stable, I use it with a VPN and AdBlock for four months
If you add a plastic box, you would have a router with unique software and hardware for 15,50 + 4,45 €
The MT7688AN as 2 pins labeled USB_DP and USB_DM . Does any one know if it is possible to add a usb connector?

Hello,
If you check the alipage you will see the two USB-pins you mentioned.
But if you check usb-pinout specs, you will notice that USB has four pins. The two on the soc are the two data pins, the other two pins needed are +5V and GND. So you can feel free to take +5V and GND directly from the power supply/its connector afaik.

All WIFI products with only B/G/N not AC ( AX ) are obsolete

Thank you!
I have to find where to recover an old female connector (may be an old charger) and make the test.
Why would you do that?
You already have the device powered up and you can (and should) take the 5V directly from it instead of using a second charger. Or am I misunderstanding something here?
The idea of the old charger is only to unsolder and use the USB connector.
Well, this discussion gets of topics, but interests me. I will open a new one

New topic:
hmmm, it's been a while, but IIRC USB1 needs pulldowns too GND from Dp/Dm on the host side.
Also for USB2 hardwiring straight to 5V/GND from the powersupply is likely to break chirping - i.e. usb2 speed negotiation.
Define "best".
Keep up-to-date list of widely available devices which satisfy:
- ALL of the properties below:
- Available today in most parts of the world
- Fully supported by OpenWRT (working both 2.4 and 5 GHz WiFi, working NICs, working swconfig)
- Stable software for everyday use - can work for at least several months without restart
- More than 4/32
- Well defined support per hardware versions if there are more than one on the market
- As many as possible of the properties below:
- Easy initial flashing (software only). Mention other available options for those who are familiar with screwdriver/soldering/serial ports etc
- Relatively cheap - compared to similar devices
- Gigabit wired ports (although this is a dealbraker for me, some people might not require them)
- Working USB ports
- Working hardware offload
- Low power consumption
Such an example is good old Archer C7 v2, but it's getting a bit old.
