Hi folks,
I just met a new vendor in Ecuador, and they're selling these routers which look
promising for LibreMesh and inexpensive. Any opinions? Think it might work well with
LibreMesh? Datasheet attached as PDF in English. Description here in Spanish. For $23, I
might buy one just to experiment.

MT7620N is a bit outdated and not the greatest chip ever made, but also
very popular and quite easy to support. 8 MB flash and 64 MB RAM is
sufficient to do everything with it. The built-in Ethernet switch is a
stripped-down version of MT7530 which is also included in MT7621 SoC
and newer MediaTek chips, so we may even enjoy DSA support for that in
the near future (and hence get rid of legacy 'swconfig' and be able to
run vanilla Linux on it and at least enjoy transparent VLAN/bridge
offloading).
Also USB is known to work reliable on that platform (SDIO and NAND for
example are only usable through low-quality and partially buggy
drivers, but this device doesn't have any of that)
The WiFi driver (rt2x00) is still being constantly improved, and help
there would definitely be appreciated -- ralink's proprietary driver
and wive-ng hacked-up versions of mediatek's newer driver with support
for the chip are easy to find as a reference to bring better support
into the Linux rt2x00 driver which is based on mac80211. So in terms of
wireless you'd definitely be better off with more recent MediaTek chips
like MT76x8 family which is equipped with a more recent wireless core
with better driver (
https://github.com/openwrt/mt76 ). Using MT7620N
as a simple 2T2R 802.11bgn access-point should work pretty well by now
though, but don't expect the same performance as you'd see with ath9k
and don't expect the same level of interest within the global developer
community as you'd see with more recent chips.
So concluding:
What is really nice are the wide-range power input and PoE output on
the WAN port.
CPU: ok (MT7620N MIPS24Kc little-endian)
Flash: ok (8MiB SPI NOR)
RAM: ok (64MB SDRAM)
Ethernet: ok (10M/100M only)
WiFi: soso~ok
MT7620*N* should be the least problematic, MT7620*A* can have external
radio components which are sometimes tricky to detect and support, but
MT7620*N* is rather trivial and the chip-support in rt2x00 was made for
that variant -- but still, don't expect the performance of ath9k or
mt76; or bring the will to actively help improving things, there are
still things missing in the driver and I will help identifying and
re-implementing them in rt2x00.
Cheers
Daniel
